Yesterday, I asked a leading question on Twitter about the #NBN and it's negative impact on #globalwarming.
I got a response. There is only so much you can say in 140 characters on the run.
Here is the stream and some notes I've added.
gnoll110 Given that high speed comms is one of the two drivers of globalisation. Is the #NBN, a bad move from a fighting global warming perspective.
djackmanson @gnoll110Absolutely not. The research into new energy production required to reduce global warming can only benefit from faster info tfr.
gnoll110 @djackmanson Miss my point. Localisation is a big factor in reducing fossil fuel use. High speed comm hinders localization.
gnoll110 @djackmanson #NBN is only a tool. Really depends how we use it. Helps R&D but also enabler for distributed manufacturing & outsourcing.
djackmanson @gnoll110 Not so much miss your point as disagree with its underlying philosophy. Don't think localism is the answer. Globalism...
djackmanson @gnoll110 ...with clean energy is what I prefer.
gnoll110 @djackmanson Think you're being techno-utopian. Costs of clean energy will drive re-localisation in part. Solution will have many parents.
gnoll110 @djackmanson In part, high speed comms got us from where we were in 1950 to here. Two edged sword, that one.
djackmanson @gnoll110 No good reason why cheap clean energy won't be distributed over wide-energy grids.
djackmanson @gnoll110 er, wide-*area* grids.
gnoll110 @djackmanson Clean energy will always be dearer. Fossil fuels are a once off free kick. Collecting/concentrating renewable means it's more $
gnoll110 @djackmanson It's a good place to go. But it can never be yesterday, just cleaned up.
I think the improvement to research from the #NBN would be marginal at best. Is this an opertunity cost question? You could do a lot with $40+ billion dollar if applied directly to the problem.
It isn't a philosophical question (localisation vs clean smart grids) for me. It's a question of available energy and what we choose to maintain. It's a continuum, we are replacing cheap energy with more expense energy. Some things won't be viable any more. This has hidden consequences. As something become unviable, other activities to produced inputs for it lose their economies of scale too (increasing unit cost), thus becoming less viable too. A downward spiral to a new status quo. How much we can reduce the reduction in energy yield per energy invested (money is only an easily handled proxy), the less we will have to give up in any new status quo.
I will retract my use of 'techno-utopian', that infers finding new tech that enables grow to go on regardless. It's not where Jack is really coming from. I do think changing the energy base of our society while maintaining the basically unchanged status quo where it is, is unrealistic.
Basically we differ on where we think the new status quo is likely to be. Preferences don't come into it. I would like to be wrong, I like my weekend trips interstate to #railscamp.

Coalless steel
Over on ABC's Unleashed there is a article called 'A renewable reality: don't let politics get in the way'.
http://www.abc.net.au/unleashed/stories/s2932909.htm
In it I got onto the energy needed to make steel. I said steel could be made and was challenged on that point. I knew that steel had been made with charcoal pre early 18th century. What I didn't realise is that do to its total lack of coal, Sweden currently has at least some charcoal based production! ;)

Global Warming: Why 'Go Veg' and cattle miss the point!
Yesterday, Cameron Reilly (@cameronreilly) posted a 'Go Veg' link on twitter. John Johnston (@jjprojects) and I commented on it. This is a topic where 140 character just isn't enough. Here are the relevant parts of the Twitter stream and me considered ramblings about the topic.
The stream
@cameronreilly: "Eat less meat and dairy: official recipe to help health of consumers – and the planet" ( http://bit.ly/68BdWt )
Me: @cameronreilly "Eat less meat" http://bit.ly/68BdWt still misses the point. Use no fossil fuel, end of cheap fuel will fix any meat problems
@jjprojects: @cameronreilly In Tim Flannery's latest essay, Now or Never, he calls for farming practices to change dramatically, rather than going veg...
@jjprojects: @cameronreilly There seems to be a bit of a debate about what is sustainable in terms of eating meat or veg and how it's grown.
@jjprojects: @cameronreilly Great essay btw, if you haven't read. He got my attention, that's for sure.
@jjprojects: @cameronreilly That would be good. There's also a great chapter about his vision for Oz cleantech, including a new, sustainable city.
@jjprojects: @cameronreilly ...for Oz to lead cleantech on R&D and innovation and export the results. Bold vision. Well worth reading.
Me: @cameronreilly re cattle. The real issues is the source of the flow. 'Cattle carbon' is part of C cycle, in one end out the other.
Me: @cameronreilly natural flows of carbon dwarf the added fossil fuel flows, in size. But the 'new' carbon throws the whole system out of wack
Me: @cameronreilly Cattle don't eat fossil fuel and are natural. But cheap fossil fuel has lead to greatly increase number.
Me: @cameronreilly So cutting cattle numbers is treating a symptom of cheap fossil fuels, not the cause.
@cameronreilly: @gnoll110 so you're saying if we make transport more expensive, people will eat less meat?
Me: @cameronreilly There are lots of fossil fuel input in beef. Transport is one, think about input to grain used in lot feeding...
Me: @cameronreilly ... and in supermarkets, in the home. Increased energy cost ripple across the whole economy...
Me: @cameronreilly ...everyone changes their ways, that how carbon taxes work too. Expect dearer beef that grass fed and produced closer to home
My ramblings
There are so many angle to this. Think I'll try a top down one.
People are talking about 'what the atmosphere sees' in regard to greenhouse gases. I think this is way to simplistic, where a holistic system view is what is really required.
Why is this too simplistic?
Firstly, the interchange between the atmosphere and the other major components (the oceans, soil and biomass) of the bioshere is both dynamic and large, to just measure and pay attention to the atmosphere alone. Of the extra carbon added to the atmosphere by fossil fuel burning each year, about half has moved to other components within a year.
Secondly, all the carbon is being treated the same regardless of whether it's part of a natural or artificial flows.
How can we view it more holistically?
I'm going for borrow an analogue from peak-oiler Richard Heinberg: a bottle of wine. How do you make wine. You put yeast in sugary water (grape juice) and let them do what come naturally. Reproduce, consuming their wonderful abundant source of easy energy. In the process, they produce a toxic pollutant, alcohol. What you end up with is water with most of the sugar gone, lots of alcohol and the detritus of the yeast population collapse at the bottom.
Lets do some substitution.
yeast = humans
sugary water = fossil fuels (both coal & oil)
alcohol = greenhouse gases
Now lets generalise in terms of the universal ecological dilemma.
Humans are population pressure
Fossil fuels use is resource depletion
Greenhouse gases are habitat destruction
We, as a species, have used the last 250 years of fossil fuel to grow our population, both in shear size and in consumption per capita. It looks like habitat destruction is going to be an issue before resource depletion, just.
How do we undo this habitat destruction,
Remove the input of 'new' fossil fuel carbon! That by itself is likely to be enough. Just hope we haven't triggered for run away feedback in the mean time.
Why is cutting cattle number just fiddling? There is an annual photosynthesis cycle. In the spring & summer plants remove net CO2 from the atmosphere and in the autumn & winter it's released back to the atmosphere in net term. Because most land is in the northern hemisphere, this annual cycle clearly shows up in atmospheric CO2 graphs. In the graph, note how the annual peak to trough movement is considerably larger that the annual peak to peak change of the underlying trend. This shows that the natural seasonal carbon flows are larger that the 'new' artificial flow that is the result of fossil fuel burning, as I noted in my twitter update above. Cattle carbon is part of this flow of carbon from biomass back to the atmosphere.
Cut cattle number and what happens? The vegetation will be eaten by other domestic animals (and back to the atmosphere), lamb anyone? In places where there is no domestic animal, a combination of two things can happen. It will be eaten be native and feral animal or it won't be. If it's eaten, back to the atmosphere. What happens to uneaten vegetation? In temperate climate it rots in a year or two, releasing the carbon back to the atmosphere. In dry climate, in a health ecology, its gets eaten (and back to the atmosphere). If the ecology is unhealthy (near death) and thus lacks the grazers, is just sits there. Occasionally fire might burn it (again releasing carbon back to the atmosphere), but without the stomach of the grazers to fore fill the role played be temperate rains, the ecology remains near death. Imagine the great savannahs of Africa without their great herds.
So in any healthy ecology, the grazers do their thing. Remove cattle and the carbon just flows back to the atmosphere via other species (or maybe fire).
Cattle are problematic for two reasons. Their emit a higher ratio of their carbon as methane, a shorter livid, but a 'hotter' gas. Modern cattle production has become fossil fuel intense, by maximising cheap inputs (fossil fuel) & minimising expensive inputs, especially labour. I haven't read Tim Flannery's latest essay, Now or Never. I suspect his call for farming practices to change dramatically will match mine.
I'm sure big oil & coal are delighted be this simplistic push to 'go veg'. Like simplistic carbon accounting, it's a distraction from the underlying fossil fuel cause.
I've already said the real solution is cutting fossil fuel use, preferably to only non energy uses like plastics. That means the end of cheap energy, that's a fundamental change to the whole economy. Doing it would create an inflationary period like that of the 1970's. That inflationary period was partly caused by the first oil shock. This inflation would not be constant across the economy, high energy application would be worst hit. This inflation would change how business is done and what people consume.
How to cause this inflation? An emission trading system (ETS) is just shifting deck chairs. A carbon tax would have an effect, but doesn't target fossil fuel specifically. I would incrementally raise petroleum fuel (liquid & gas) excises and coal royalties based on carbon content. That is what helps bank rolls the required restructuring both domestic & internationally.
Cattle production would move back to traditional grass feed systems and shirk as people cut their consumption to meet their reduced buying power. Transport & refrigeration costs would change the way beef is consumed. More local, less big box, more eat-the-day-you-buy for most of our food stuffs. Not just 'make transport more expensive, people will eat less meat?'. A fundamental change to business as usual.

Why Co Gen is not just distraction
Yesterday, I tweeted about an Insider Business story on Co Generation (Co Gen). Co Gen is where in a power generation process, you also harvest heat as stream or hot water. @Olga_Galacho and I had a bit a a dialogue about it. This is a topic where 140 character just isn't enough.
The conversation:
Me: #insidebusiness Looking at BlueGen co gen box. Still trying to think of ways to get cattle to shit in the one spot! http://bit.ly/3gNWIl
Me: @Olga_Galacho did you see #insidebusiness today. Had story about co gen box & it's Aussie manufacturer. http://bit.ly/3gNWIl
@Olga_Galacho RT @gnoll110 did you see #insidebusiness today. Had story about co gen box & it's Aussie manufacturer. http://bit.ly/3gNWIl
@Olga_Galacho @gnoll110 co gen is a distraction from the main game. it helps a little, but we should be putting our energies/money into pure renewables
Me: @Olga_Galacho I was looking at using methane, not petroleum gas. Co gen as part of a integrated distributed power grid http://bit.ly/1SeIPS
Me: @Olga_Galacho Always take systems apart. CoGen is abt combustion to generate power, while harvesting useful heat. Then question what to burn
Me: @Olga_Galacho the point is that the methane in cow shit was in the atmosphere a year ago, it's bioshere carbon, not fossil #carbonaudit
@Olga_Galacho @gnoll110 either way, you burn something, you produce GHG- all cogen does is partly filter the crap - still get crap, just less
@Olga_Galacho @gnoll110 cogen really just serves to justify continuing to validate ff sector - a stepping stone to avoid methinks
Me: @Olga_Galacho If you think co gen is to be avoided then you need to understand the carbon cycle. My view on Algae http://bit.ly/1WDcJq
Me: @Olga_Galacho correct to 2 tweets back 'the methane in cow shit' should bave read 'the carbon in methane in cow shit'
Expanding of my tweets (aka why 140 character is never enough)
In the Inside Business story they talked about burning petroleum gas. I'll agree with Olga here. It's just burning fossil fuel more efficiently. This isn't an affective global warming strategy.
But to use gas powered Co Gen to simple dismiss Co Gen misses the full implications of the technology, particularly in a distributed electricity grid context.
It really does come down to what you burn and where's it comes from.
What you burn? I would think you could burn methane with little modification in the BlueGen box. The Americans, British and Europeans have a tradition of heating using domestic furnaces. I've only seen this kind of heating used in a small number of schools in Australia. Co gen is one step up from this, generation high grade electricity from the combustion, before it is dispersed as low grade heat. The Austrians are using wood pallet powered co gen in some their apartment block sized heating systems. Clearly, wood pallet isn't a fossil fuel. Therefore, if the production is done correctly, it is a sustainable fuel.
Where's it from? I've said before that "Carbon accounting strike me as simplistic, quantitative (at the expense of qualitative) and proven to creative accounting. Very spinable". Accounting methane is an good example of where you need to be qualitative. Methane can come from any number of sources. For simplicity, I'm just going to use two in this accounting. Coal seam methane and cow shed methane.
Coal seam methane is clearly a fossil fuel, even if the Federal Govt. has included it in the Renewable Energy Target. *poke*
Cow shed methane is part of the ongoing carbon cycle. The carbon in methane came from the grass the cow eat. That grass photosynthesised that carbon out of the air over that last year. A year ago it was most likely in the atmosphere. Don't count this carbon!
Cattle methane has subtle complex. Remember we have far more cattle now than we did 250 years ago, at the start of the Industrial Revolution. The reason we have so many cattle is that we used that wealth of energy from coal and oil to improve production and lifestyle, including increases in meat and milk consumption. Even the quantity of cattle methane is fossil fuel related.
I don't think it should be accounted in Carbon budgets. Why. Because the number of cattle is tied to fossil fuel, as we wean ourselves off fossil fuels, the increased cost of meat and milks production will reduce the numbers of cattle. For example, in Australia, is means that the least viable farm lands with go back to scrub and forest. This both improves local rainfall and increases timber yield. What happens to total yields. How knows? Improved rainfall, changes in technology and practices, and more people involved in agriculture due to less fossil fuel; all effect yield in unforeseeable ways.
The carbon in cattle shit is part of the back ground 250ppm of CO2 in the atmosphere. Part of the seasonal ebb and flow in the atmospheric carbon level.
Stop introducing fossil fuels into the biosphere and the carbon cycle will rebalance itself if we let it.
Harvesting an in balance local system means taking yield where ever one can. Be it vegetable, meat or fibre.
Going veg is a poor substitute for the hard job of going cold turkey on fossil fuels and living locally.
Update:
After I posted this post, the conversation re-continued on twitter. I've added some notes in italics.
@Olga_Galacho @gnoll110 have to fess i didnt read the link...will do and revisit my tweets @gnoll Had story about co gen box & it's Aussie manufacturer
Me: Yesterday, @Olga_Galacho & I tweeted abt Co Generation (Co gen). One of us thinks it's a distraction, the other doesn't http://bit.ly/1cMMwJ
@Olga_Galacho @gnoll110 You want to harvest cow shed methane? Like battery cows as opposed to free range cows? #Co-Generation
Me: @Olga_Galacho lol No. People harvest methane from dairies at milking time. Cattle shit any where. Imagine if toilet trained like cats!
Me: @Olga_Galacho by the way, they do have battery cattle, it's called feed lotting.
@Olga_Galacho RT @gnoll110 Cattle shit any where. Imagine if toilet trained like cats!
@Olga_Galacho @gnoll110 we cld train em to tweet too, so we learn what they think of this http://www.animalaid.org.uk...
Just great, feed lotting in the dark!
Me: @Olga_Galacho Feed lotting is not a sustainable practice. To much oil needed and don't like the practice from welfare point of view.
@Olga_Galacho @gnoll110 Im sticking to my guns...u cant right a wrong with another wrong ...#co generation doesnt impress me enough
@Olga_Galacho @gnoll110 dont be selective & forget to add ALL my tweets in this #co gen dialog with u to your blog http://bit.ly/1cMMwJ :)
Done, too much cut & paste :P
Me: @Olga_Galacho Yer, will add the new tweets. Complete when I started writing. I still say co gen has place in an integrated local environment
Me: @Olga_Galacho "cant right a wrong with another wrong" What are the two wrong? Just see co gen as tech. Pick what you need for your situation
@Olga_Galacho @gnoll110 Ok, we'll have to agree to disagree. When I get my blog started, I'll tell u why in more than 140 characters :)
Me: @Olga_Galacho Just a high tech pot belly stove. You choose where to put it and what to fuel it with.
Me: @Olga_Galacho Real problem is that we've become addicted to the vast amounts of energy that fossil fuel produces. Need to cut the habit!
@Olga_Galacho @gnoll110 wrong 1. methane. wrong 2. burning methane. & yes i know methane is more wicked than co2
@Olga_Galacho @gnoll110 it follows that if u encourage All #co-gen then u encourage greater harvesting of fossil fuels for combustion.
Missed this post in the stream. The key word in All. I'm talking about using biomass. Carbon that's already in the carbon cycle.
@Olga_Galacho @gnoll110 including methane in RET was immoral
That depends on the methane's source, coal seam is a big no. Cow shed/Dariy methane is fine for RET.
Me: @Olga_Galacho Fine, ignore methane. Use wood pallet from forestry by cuts & coppicing. It's small scale, ideal for integrated local economy.
Me: @Olga_Galacho as long as the ash ends up back in the forest/wood lot, system is still sustainable. Sun light in > electricity out.
@Olga_Galacho nope - fewer cows, fewer felled trees. Like I said, dont feed a bad habit RT @gnoll110 @Olga_Galacho Fine, ignore methane. Use wood pallet
Think we well end up with fewer cattle, as meat & milk become more of a luxury. Without fossil fuels, the landscape need to be work again for energy as well as food. See more tree felling, Ben Law style, not less in a post fossil fuel world.
Me: @Olga_Galacho If you drop fossil fuels then you're back to solar, wind, hyrdo, bio mass etc. Like we did before 1750AD, but with more tech.
Me: @Olga_Galacho For me its not weather a particular substance is good or bad. Its the system that produced it.
@Olga_Galacho @gnoll110 Now you're talkin my lingo RT @gnoll110 @Olga_Galacho If you drop fossil fuels then you're back to solar, wind, hyrdo, bio mass
Me: @Olga_Galacho Coal seam methane = bad. Open grazed dairy = good. Remember that scale of these things will reduce greatly if no fossil fuels.
Me: @Olga_Galacho I think you'll find these co gen systems are efficient in the bio mass to energy stakes.
Think our main source of difference is our different professional backgrounds. Olga as the story telling Journo versus my take it apart and flog the useful bits Analyst/Programmer outlook.
Update, the second
@Olga_Galacho RT @gnoll110 http://bit.ly/1cMMwJ Olga as the story telling Journo versus my take it apart and flog useful bits Analyst/Programmer outlook.
@Olga_Galacho @gnoll110 Im going to take offence at being called a story teller ... where do you get off, Mr Analyst/Programmer
@Olga_Galacho @gnoll110 analyse this: Im not telling a story. Im telling the facts. Facts are too much energy time money being spent on distractions
@Olga_Galacho @gnoll110 Cut the middle man (technology) out and go straight to main game (centralised & distributed renewables) then cows can fart away
@Olga_Galacho @gnoll110 I object to your last word on http://bit.ly/1cMMwJ I challenge you to add my tweets from this evening
Me: @Olga_Galacho Story teller is good, it a skill I wish I had. Look at #4corners this week.
Me: @Olga_Galacho Facts are generally boring, pgs & pgs of boring. It taking all that facts & building story for the street that's media's job
Me: @Olga_Galacho If you read again, I said we use to much energy now, that's what 'scaling down' is all about.
I'm serous Olga, from my point of view, media's main job is collecting facts and sub stories, then analysing them and building new interesting holistic stories that the street can understand and be educated by. Given how tabloid media uses its story telling skill, I can understand why the term 'story telling' is one you don't want used. If you don't tell a story at all, then your article would be dry proses with lists of references to relevant books, papers and other sources. The stuff of scientific & industry journals. Something that would be read be others already interested in the topic, but not by the street.
Your holistic story (top down) and my reductionist pulling it apart (bottom up) are both of use here. I was just saying we started looking at this from different angles.
I apology for any hurt using the term 'story telling' may have caused, none was intended.
I do understand that we need to use far less energy to fit back into the Earth's 'annual solar energy budget'. That is why I said we need to harvest all renewable sources. It's a rather large turkey we need to go cold on.
Cattle methane is a renewable. They don't eat coal & petroleum. They eat grass that is partly carbon photosynthesised out of the air over the last year, generally. By definition this makes it a renewable too. I'm serous here too. I said it's all about analysing the cycles of nature, particularly energy and carbon. Nitrogen is an interesting cycle to follow too, but that's another story. To not include cattle methane as a bio mass renewable show this analysis of the carbon cycle wasn't done. You may think it too small scale to be useful, but it is still a renewable.
True, the main game for big cities is likely to be is centralised long distance renewables (note I use 'long distance' instead of 'distributed'). I think for towns, rural & remote, the future is many distributed small local energy sources.
Personally I think 'private wire' systems (local unconnected wire systems owned by local co-ops) are a good thing for rebuilding local economies. Exactly because they cut out the middlemen. I'm also sure big business will fight to keep them illegal and unviable using lobbyists, the law, red tape and all the games (near) monopolies play.
System leakage in moving food and power over distance when combined with the steeply increasing value of the energy being lost has implication. I think that ultimately this factor will halt to the growth and then shrink large cities in the long term.
Olga, I'm sticking to me gun here. I do think it's our difference professional outlooks that is the difference. I think you see it as a distraction because you're looking at the short term, big picture story of big fossil fuel using co gen as a stop gap, that in turns delays renewables take up. I see it as a useful bit of new tech in a small package that can harvest energy from environmental energy/carbon flows in well managed post fossil fuel farming & forestry. If me view of your objections to co gen is difference, please say.

@Olga_Galacho @gnoll110 Repeating I don't disagree with all you say-just don't want to be distracted from, dare I say the dirty word, BASELOAD, renewables
Methane and wood pallet are both baseload renewables. Both can be stored and then burnt when the energy is needed. I understand Austrian companies routinely remote monitor and control apartment size co gen systems across Europe.
There are many battery systems that can be used for storing energy from wind and photo voltaic solar.
As you may have guessed, my favourite technology is the Molten salt thermal system. Like the idea of using for a material that's common and some times a problem.
It this point I'll remind people that there are Solar thermal systems that like methane and wood pallet, include storage/battery function in their design.
I don't think baseload wind and photo voltaic solar is a technical question. It's primaryly a political question.
While Renewable Energy Targets (RET) are low and can include fossil fuel sources like coal seam methane & petroleum gas, there is not reason to add batteries to grid connected wind and photo voltaic solar systems. Why add the expense of batteries while coal and petroleum gas can still be used. You only need to start adding batteried wind and photo voltaic solar when the peak output from these systems gets to a size that it matches total demand in the lowest demand periods. Until this happen there is no reason to 'time shift' energy using batteries.
The refinement of these battery technologies won't happen until governments raise their RET targets to a point where batteried systems must be used. I don't see that happening until a working global agreement on global warming is reached. China & India ain't ready to deal, so I see battery improvement research remaining in limbo with only token green wash money being spent.
Olga, I agree, these methane & wood pallet are generally not applicable in metro area. That's a problem for metro areas, not these systems. Because these systems use trees or grasses and animals to concentrate sunlight as bio mass, they have a natural head start on wind and photo voltaic solar. It remains to be seen if vested interests and economies of scale will produce an energy economy with one or two 'main games'. Pre 1750AD, the landscape was a mosaic of overlapping small systems. The mix determined by the geography, climate, biology and tech at that place and time. Both 'main game' & mosaic are possible, time will tell.

The conversation:
Me: #insidebusiness Looking at BlueGen co gen box. Still trying to think of ways to get cattle to shit in the one spot! http://bit.ly/3gNWIl
Me: @Olga_Galacho did you see #insidebusiness today. Had story about co gen box & it's Aussie manufacturer. http://bit.ly/3gNWIl
@Olga_Galacho RT @gnoll110 did you see #insidebusiness today. Had story about co gen box & it's Aussie manufacturer. http://bit.ly/3gNWIl
@Olga_Galacho @gnoll110 co gen is a distraction from the main game. it helps a little, but we should be putting our energies/money into pure renewables
Me: @Olga_Galacho I was looking at using methane, not petroleum gas. Co gen as part of a integrated distributed power grid http://bit.ly/1SeIPS
Me: @Olga_Galacho Always take systems apart. CoGen is abt combustion to generate power, while harvesting useful heat. Then question what to burn
Me: @Olga_Galacho the point is that the methane in cow shit was in the atmosphere a year ago, it's bioshere carbon, not fossil #carbonaudit
@Olga_Galacho @gnoll110 either way, you burn something, you produce GHG- all cogen does is partly filter the crap - still get crap, just less
@Olga_Galacho @gnoll110 cogen really just serves to justify continuing to validate ff sector - a stepping stone to avoid methinks
Me: @Olga_Galacho If you think co gen is to be avoided then you need to understand the carbon cycle. My view on Algae http://bit.ly/1WDcJq
Me: @Olga_Galacho correct to 2 tweets back 'the methane in cow shit' should bave read 'the carbon in methane in cow shit'
Expanding of my tweets (aka why 140 character is never enough)
In the Inside Business story they talked about burning petroleum gas. I'll agree with Olga here. It's just burning fossil fuel more efficiently. This isn't an affective global warming strategy.
But to use gas powered Co Gen to simple dismiss Co Gen misses the full implications of the technology, particularly in a distributed electricity grid context.
It really does come down to what you burn and where's it comes from.
What you burn? I would think you could burn methane with little modification in the BlueGen box. The Americans, British and Europeans have a tradition of heating using domestic furnaces. I've only seen this kind of heating used in a small number of schools in Australia. Co gen is one step up from this, generation high grade electricity from the combustion, before it is dispersed as low grade heat. The Austrians are using wood pallet powered co gen in some their apartment block sized heating systems. Clearly, wood pallet isn't a fossil fuel. Therefore, if the production is done correctly, it is a sustainable fuel.
Where's it from? I've said before that "Carbon accounting strike me as simplistic, quantitative (at the expense of qualitative) and proven to creative accounting. Very spinable". Accounting methane is an good example of where you need to be qualitative. Methane can come from any number of sources. For simplicity, I'm just going to use two in this accounting. Coal seam methane and cow shed methane.
Coal seam methane is clearly a fossil fuel, even if the Federal Govt. has included it in the Renewable Energy Target. *poke*
Cow shed methane is part of the ongoing carbon cycle. The carbon in methane came from the grass the cow eat. That grass photosynthesised that carbon out of the air over that last year. A year ago it was most likely in the atmosphere. Don't count this carbon!
Cattle methane has subtle complex. Remember we have far more cattle now than we did 250 years ago, at the start of the Industrial Revolution. The reason we have so many cattle is that we used that wealth of energy from coal and oil to improve production and lifestyle, including increases in meat and milk consumption. Even the quantity of cattle methane is fossil fuel related.
I don't think it should be accounted in Carbon budgets. Why. Because the number of cattle is tied to fossil fuel, as we wean ourselves off fossil fuels, the increased cost of meat and milks production will reduce the numbers of cattle. For example, in Australia, is means that the least viable farm lands with go back to scrub and forest. This both improves local rainfall and increases timber yield. What happens to total yields. How knows? Improved rainfall, changes in technology and practices, and more people involved in agriculture due to less fossil fuel; all effect yield in unforeseeable ways.
The carbon in cattle shit is part of the back ground 250ppm of CO2 in the atmosphere. Part of the seasonal ebb and flow in the atmospheric carbon level.
Stop introducing fossil fuels into the biosphere and the carbon cycle will rebalance itself if we let it.
Harvesting an in balance local system means taking yield where ever one can. Be it vegetable, meat or fibre.
Going veg is a poor substitute for the hard job of going cold turkey on fossil fuels and living locally.
Update:
After I posted this post, the conversation re-continued on twitter. I've added some notes in italics.
@Olga_Galacho @gnoll110 have to fess i didnt read the link...will do and revisit my tweets @gnoll Had story about co gen box & it's Aussie manufacturer
Me: Yesterday, @Olga_Galacho & I tweeted abt Co Generation (Co gen). One of us thinks it's a distraction, the other doesn't http://bit.ly/1cMMwJ
@Olga_Galacho @gnoll110 You want to harvest cow shed methane? Like battery cows as opposed to free range cows? #Co-Generation
Me: @Olga_Galacho lol No. People harvest methane from dairies at milking time. Cattle shit any where. Imagine if toilet trained like cats!
Me: @Olga_Galacho by the way, they do have battery cattle, it's called feed lotting.
@Olga_Galacho RT @gnoll110 Cattle shit any where. Imagine if toilet trained like cats!
@Olga_Galacho @gnoll110 we cld train em to tweet too, so we learn what they think of this http://www.animalaid.org.uk...
Just great, feed lotting in the dark!
Me: @Olga_Galacho Feed lotting is not a sustainable practice. To much oil needed and don't like the practice from welfare point of view.
@Olga_Galacho @gnoll110 Im sticking to my guns...u cant right a wrong with another wrong ...#co generation doesnt impress me enough
@Olga_Galacho @gnoll110 dont be selective & forget to add ALL my tweets in this #co gen dialog with u to your blog http://bit.ly/1cMMwJ :)
Done, too much cut & paste :P
Me: @Olga_Galacho Yer, will add the new tweets. Complete when I started writing. I still say co gen has place in an integrated local environment
Me: @Olga_Galacho "cant right a wrong with another wrong" What are the two wrong? Just see co gen as tech. Pick what you need for your situation
@Olga_Galacho @gnoll110 Ok, we'll have to agree to disagree. When I get my blog started, I'll tell u why in more than 140 characters :)
Me: @Olga_Galacho Just a high tech pot belly stove. You choose where to put it and what to fuel it with.
Me: @Olga_Galacho Real problem is that we've become addicted to the vast amounts of energy that fossil fuel produces. Need to cut the habit!
@Olga_Galacho @gnoll110 wrong 1. methane. wrong 2. burning methane. & yes i know methane is more wicked than co2
@Olga_Galacho @gnoll110 it follows that if u encourage All #co-gen then u encourage greater harvesting of fossil fuels for combustion.
Missed this post in the stream. The key word in All. I'm talking about using biomass. Carbon that's already in the carbon cycle.
@Olga_Galacho @gnoll110 including methane in RET was immoral
That depends on the methane's source, coal seam is a big no. Cow shed/Dariy methane is fine for RET.
Me: @Olga_Galacho Fine, ignore methane. Use wood pallet from forestry by cuts & coppicing. It's small scale, ideal for integrated local economy.
Me: @Olga_Galacho as long as the ash ends up back in the forest/wood lot, system is still sustainable. Sun light in > electricity out.
@Olga_Galacho nope - fewer cows, fewer felled trees. Like I said, dont feed a bad habit RT @gnoll110 @Olga_Galacho Fine, ignore methane. Use wood pallet
Think we well end up with fewer cattle, as meat & milk become more of a luxury. Without fossil fuels, the landscape need to be work again for energy as well as food. See more tree felling, Ben Law style, not less in a post fossil fuel world.
Me: @Olga_Galacho If you drop fossil fuels then you're back to solar, wind, hyrdo, bio mass etc. Like we did before 1750AD, but with more tech.
Me: @Olga_Galacho For me its not weather a particular substance is good or bad. Its the system that produced it.
@Olga_Galacho @gnoll110 Now you're talkin my lingo RT @gnoll110 @Olga_Galacho If you drop fossil fuels then you're back to solar, wind, hyrdo, bio mass
Me: @Olga_Galacho Coal seam methane = bad. Open grazed dairy = good. Remember that scale of these things will reduce greatly if no fossil fuels.
Me: @Olga_Galacho I think you'll find these co gen systems are efficient in the bio mass to energy stakes.
Think our main source of difference is our different professional backgrounds. Olga as the story telling Journo versus my take it apart and flog the useful bits Analyst/Programmer outlook.
Update, the second
@Olga_Galacho RT @gnoll110 http://bit.ly/1cMMwJ Olga as the story telling Journo versus my take it apart and flog useful bits Analyst/Programmer outlook.
@Olga_Galacho @gnoll110 Im going to take offence at being called a story teller ... where do you get off, Mr Analyst/Programmer
@Olga_Galacho @gnoll110 analyse this: Im not telling a story. Im telling the facts. Facts are too much energy time money being spent on distractions
@Olga_Galacho @gnoll110 Cut the middle man (technology) out and go straight to main game (centralised & distributed renewables) then cows can fart away
@Olga_Galacho @gnoll110 I object to your last word on http://bit.ly/1cMMwJ I challenge you to add my tweets from this evening
Me: @Olga_Galacho Story teller is good, it a skill I wish I had. Look at #4corners this week.
Me: @Olga_Galacho Facts are generally boring, pgs & pgs of boring. It taking all that facts & building story for the street that's media's job
Me: @Olga_Galacho If you read again, I said we use to much energy now, that's what 'scaling down' is all about.
I'm serous Olga, from my point of view, media's main job is collecting facts and sub stories, then analysing them and building new interesting holistic stories that the street can understand and be educated by. Given how tabloid media uses its story telling skill, I can understand why the term 'story telling' is one you don't want used. If you don't tell a story at all, then your article would be dry proses with lists of references to relevant books, papers and other sources. The stuff of scientific & industry journals. Something that would be read be others already interested in the topic, but not by the street.
Your holistic story (top down) and my reductionist pulling it apart (bottom up) are both of use here. I was just saying we started looking at this from different angles.
I apology for any hurt using the term 'story telling' may have caused, none was intended.
I do understand that we need to use far less energy to fit back into the Earth's 'annual solar energy budget'. That is why I said we need to harvest all renewable sources. It's a rather large turkey we need to go cold on.
Cattle methane is a renewable. They don't eat coal & petroleum. They eat grass that is partly carbon photosynthesised out of the air over the last year, generally. By definition this makes it a renewable too. I'm serous here too. I said it's all about analysing the cycles of nature, particularly energy and carbon. Nitrogen is an interesting cycle to follow too, but that's another story. To not include cattle methane as a bio mass renewable show this analysis of the carbon cycle wasn't done. You may think it too small scale to be useful, but it is still a renewable.
True, the main game for big cities is likely to be is centralised long distance renewables (note I use 'long distance' instead of 'distributed'). I think for towns, rural & remote, the future is many distributed small local energy sources.
Personally I think 'private wire' systems (local unconnected wire systems owned by local co-ops) are a good thing for rebuilding local economies. Exactly because they cut out the middlemen. I'm also sure big business will fight to keep them illegal and unviable using lobbyists, the law, red tape and all the games (near) monopolies play.
System leakage in moving food and power over distance when combined with the steeply increasing value of the energy being lost has implication. I think that ultimately this factor will halt to the growth and then shrink large cities in the long term.
Olga, I'm sticking to me gun here. I do think it's our difference professional outlooks that is the difference. I think you see it as a distraction because you're looking at the short term, big picture story of big fossil fuel using co gen as a stop gap, that in turns delays renewables take up. I see it as a useful bit of new tech in a small package that can harvest energy from environmental energy/carbon flows in well managed post fossil fuel farming & forestry.

Why Kyoto mean nothing, personally what to do next?
During the Internet chatter about the recent Eastern Australia Dust Storm. Some overseas people quipped about Australia not being a signatory to the Kyoto Protocol. Others returned fire, saying that Australia had (two years ago). Some even then went on to figure point at the US.
Here is my thoughts about why Kyoto was always irrelevant.
Most countries that 'signed up' don't have any commitments (that was the only way to get them to sign). Most (All?) of those that did sign with commitments look like they won't meet their commitments.
The nature of the problem class (Tragedy of the Commons) means that everyone need to sign up to an agreed system of determining commitments. So they know what level of development will trigger commitments and what those commitments will be. The nature of the problem also meaning any action now (before global agreement) is only political manoeuvring and tokenism, and has no effect on the actual atmospheric carbon levels & climate. For every 'cow' you take off the commons, someone else will putting another 'cow' on (in China and India most likely).
As I've always said, there is no chance of global agreement until China & India fear civil unrest due to global warming (famine etc) more that they fear civil unrest due to poverty (staving because you're jobless). Don't think they are there yet, so I don't think anything will come from Copenhagen. Mind you the rhetoric from India in New York this last week in encouraging.
How best to spend your limited resources?
Building low carbon systems and building for resilience. What kinda low carbon systems to build now?
Resilience simply mean to do things to lessen the effect of global warning on you. Learn to grow you own food, add a rain water tank, renovate your house to be more solar passive, that kinda thing.
By all means build low carbon power sources, but remember what is important is only emissions during operations. You can emit all the carbon you want building it, you're only replacing coal fired power station carbon, in the race to get to China & India's climate pain threshold. Who know where the actual thresholds are? Guess we'll only know after we get there and everyone comes to a meaningful agreement!

Algae Farming and it's Carbon
A few days ago, David Rush, @EcoEngineering over at Twitter, tweeted about Aquentium buying a New Mexico site for an Algae farm.
I responded with a comment about one line in the press release that looked funny to me. Here our conversation.
@EcoEngineering: Aquentium Announces 475 Acre Algae BioFuel Production Project - World Stock Wire (press release) http://bit.ly/mQWf1
Me: @EcoEngineering "Aquentium’s algae-based fuels will emit approximately two-thirds less CO2..." ??? shouldn't an algae system be GHG neutral?
Me: @EcoEngineering CO2 in at pond = CO2 out when it's burnt to product power/motion?
@EcoEngineering: Thx @gnoll110 So your saying more efficient algea system=more fuels to burn=more GHG. Good point!
Me: @EcoEngineering No, that if they don't feed the algae with coal/oil & make the setup using algae fuel, how can it not be GHG neutral?
Me: @EcoEngineering that is, as long as the setup is made using algae fuel, how could if be GHG positive? (all C from the air to start with)
Me: @EcoEngineering isn't the Atlantic Conveyor sinking and depositing huge amount of C (dead algae) of ocean floor how bioshere get ride of C?
Me: Carbon accounting strike me as simplistic, quantitative (at the expense of qualitative) and proven to creative accounting. Very spinable.
@EcoEngineering: Sorry @gnoll110 I think we're on different pages.
@EcoEngineering: @gnoll110 Send me a little more info so I can formulate a response please.
The above comments where made in reference to on-going operations. In a reply I've included the 'build' carbon too. I think a working Algae farm should be greenhouse gas (GHG) negative to start with and over time become slightly GHG positive once all fossils fuel usage (as a fuel) is replaced.
My reply to David and anyone who's interested.
Second attempt at a response. First one was turning into Ben-Hur.
Here is how I see it.
All the carbon in algae come from the atmosphere in the first place, so any burning process no matter how efficient or inefficient should be neutral at worst. Indeed an inefficient burn that produced an algae-char replacement for bio-char (charcoal) could make the process helpfully GHG negative.
Now lets switch to the energy front.
I going to assume that the total energy production over the life of the algae farm & associated processing chain is greater than the total energy consumption involved in building and operation said algae farm & processing chain. (if this is not true what we really got is most likely a coal to oil plant, and a different ball game).
Given the algae farm is a net energy producer, I'm going to assume these guys eat their own dog food and this means:
* they built the farm & chain using energy from the last one they built and
* that operational energy will be drawn from the farm & chain's previous operations
If the above is true, the carbon footprint is the physical carbon embedded in making the steel and other manufactures (ie coking coal needed to make the steel).
In reality this is likely not to be true. I.e. the bio-mass oil produced is likely to be used for transport, while the chain is operated by gas fired electricity (or some other non transport grade energy source). I'm not including this in my logic because this factor is highly situational.
Back to the carbon front.
Assuming that the net energy produced is going to replace the 'worst carbon energy source'. Isn't this what emission trading systems (ETSs) do? Act as a pricing mechanism to transfer resources between players. (I'm not including net changes to total human energy demand, that shouldn't effect the carbon & energy budget of individual artefacts).
Shouldn't any carbon cost of building and operating the farm & chain be far less than the carbon cost of building/continued operation of the low cost 'worst carbon energy source' that it replaces.
Granted the shut down of the low cost 'worst carbon energy source' won't happen on the day the algae farm & processing chain go operational. But the low cost high carbon alternative won't start either. Over time (and assuming governments don't corrupt the working of an international ETS system that includes an escalating carbon cost) the 'worst carbon energy source' will get replaced.
*** A working International Climate Change Agreement that a working International ETS system would be based on is a PRE-CONDITION to successfully fighting Global Warming (what the Australian Labor Party (ALP) is pushing atm does not meet these conditions and thus is a waste of current effort and may have big opportunity costs) ***
If the above happens, isn't an algae farm going to be GHG negative. The better the gross energy production:gross energy cost ratio (for the total life cycle), the more GHG negative the algae farm should be.
At some future date.
Repeating the no build/closures of 'worst carbon energy source' cycle over time would get you to the situation where the next algae farm itself becomes a 'worst carbon energy source'. One would hope that the base carbon cost is building an algae farm without the 'worst carbon energy source' offsets (offset = 0), is low enough that at that mythical future date when the human world as run by algae farm, the carbon load will be well within the Earth's ability to absorb (on an annual basis).
Update: If you get metal recycle percentages increasing, the net energy production would drop. but fossil fuel usage (as a feed stock, not a fuel) would drop too. This would close the introduction of fossil fuel (new) carbon into the carbon cycle down even more. More new carbon now (before the peak carbon), less new carbon later (at and after peak carbon): a good thing.
The end.
David, peer review to you hearts content. This in just a thought experiment on my part. Hope people find it helpful.

*** A working International Climate Change Agreement that a working International ETS system would be based on is a PRE-CONDITION to successfully fighting Global Warming (what the Australian Labor Party (ALP) is pushing atm does not meet these conditions and thus is a waste of current effort and may have big opportunity costs) ***
If the above happens, isn't an algae farm going to be GHG negative. The better the gross energy production:gross energy cost ratio (for the total life cycle), the more GHG negative the algae farm should be.
At some future date.
Repeating the no build/closures of 'worst carbon energy source' cycle over time would get you to the situation where the next algae farm itself becomes a 'worst carbon energy source'. One would hope that the base carbon cost is building an algae farm without the 'worst carbon energy source' offsets (offset = 0), is low enough that at that mythical future date when the human world as run by algae farm, the carbon load will be well within the Earth's ability to absorb (on an annual basis).
Update: If you get metal recycle percentages increasing, the net energy production would drop. but fossil fuel usage (as a feed stock, not a fuel) would drop too. This would close the introduction of fossil fuel (new) carbon into the carbon cycle down even more. More new carbon now (before the peak carbon), less new carbon later (at and after peak carbon): a good thing.
The end.
David, peer review to you hearts content. This in just a thought experiment on my part. Hope people find it helpful.

World's Greenest Homes: just a Coffee Table Book
Over the last two Thursday, first two episodes of World's Greenest Homes has gone to air on ABC1.
It does not stand up well against Grand Designs.
This tweet about sums it up: #worldsgreenesthomes is a glossy coffee table to #granddesigns DIY manual, comparatively. Good for a few ideas, no detail.
Im going to tweet the good points of each hone as I watch each program. You can search for them with this Twitter Search.

Doing a toaster from scratch
Found this hand made toaster url in my twitter stream. Love New Scientist, had to have a look.
An £5 manufactured artifact cost £1200 to put together from scratch. How far we have come in 250 years. Glad I don't have to be a Shepard because we hadn't got around to inventing fencing wire!
Now to figure out what I can do without to fit back into a 'Annual Solar Input' budget. You know the amount of energy get without burning fossil fuels!

Batteries and Oil to Solar
Talk on twitter last night got on to the topic 'oil to solar'. I think the topic needs a post about batteries just to make things more informed and complex.
The are 3 battery types I wish to expend on. What I call electrochemical, potential energy and thermal.
Electrochemical
These are what we normally think of as batteries. It covers many chemical reaction the produce electrical current. They are all example of Galvanic cells. The two most common are the Lead-acid battery used in cars and the ubiquitous Alkaline battery of screaming children on Christmas day fame. Some are rechargeable, some aren't.
In some application, like electric cars, where size and weight is an issue there a many exotic reactions under consideration. Being exotic, cost and rarity become an issue for wide spread application becomes.
At the other end of the scale is the Nickel-iron battery. An old, bulky and relatively benign chemistry that uses cheaper common materials.
Potential Energy
This type of battery system is not common, but where the situation is right, it can be very large store of energy. It involves two bodies of water at different heights (the bigger the difference, the better). Water is pumped from the low storage to the high storage when excess power of available. When power is needed the water is allowed to return to the lower storage, generating hydroelectric power in the process.
Thermal
These are systems where energy is store at heat. The simplest example is a well design fireplace. A single evenings fire can stores enough heat is the mass of the fire place to keep a well insulated rooms temperate elevated for 48 hours.
I divide these systems into Low temperature differential (LTD) and High temperature differential (HTD). LTD is where the store's temperature is less than 100C above ambient and HTD is where it's greater than 100C above.
A example of a LTD system is a Solar pond. An idea battery for providing heat to industrial processes like desalination. Electricity can also be generated using LTD heat engines.
A example of a HTD system is a Molten salt thermal system (not to be confused with Molten salt electrochemical batteries). There are many salts and these many temperature ranges to play with here. Right up to like 1600C, which start to made designs trickier/more expense, since common materials like iron & steel also melt at these higher temperatures.
Hope this gives people an idea of the range and have exotic battery systems can get.

Can Capitalism save the Rain forests?
Tonight, ABC’s Foreign Correspondent is showing a programs entitled 'Amazon Rainforest - Can Money Grow on Trees?'. Without see the program, I going to say yes.
Why? For me it’s a matter of first principles of economics and ecology. The very words themselves point to the way forward. Both are derived from the Greek ‘eco’ (oikos), meaning 'house'.
I will argue the economics is the ecology of human societies. Money is a token measure of energy and materiel. Ecology is a study of the measure and flows of energy and materiel in the wider biosphere. Classical economics is the study competition between individual and organisation. There is cooperation and other behaviors that are seen in ecology. Lots of strategies and tactics are displayed by organisms. Taking these and applying them to economics problems and situation should be the main source for developing viable global warning measures.

DNC, Biden and The Oil Drum on Trains and Peak Oil
It Democratic Nation Convention time in the US at the moment. I'm going to pull a few thread together and point at some goodness that could follow.
The Democratic VP candidate Joe Biden is a well know rail champion. He could be a major factor in taking some major peak oil/global warming action in the US (if elected).
Last year I blog on what we should be doing in Queensland and Australia generally.
Last month, TheOilDrum a peak oil site, ran a great article about railway electrification in the US. Lots of debate and chatter persued, all good value :)
Here are wikipedia's notes on railway electrification (root page), and pages related to the UK and the US.
If Joe Biden does choose to pursue this and succeeds, it will likely be his greatest contribution to his country. It would be what he's remembered for, short of getting himself enpeached. So Joe, no late night expedition to the Republican Party Nation Headquarters!

Been reading Alternative Technology Association's (ATA) ReNew magazine. The current edition (#104, July-Sept 2008).
It has a great article entitle Guerrilla solar in the Aussie 'burbs. It's sub headed Installing grid-connect solar can be a frustrating process. Some people just give up and do it their own way, writes Avery 'Sonny' Daze and Jenny Rait.
It talks about putting a small system together. The dirty games that utilities play and getting a systems connected.

We hold these truths to be self-evident that all energy is freely and democratically provided by Nature, that utilities both public & private have no monopoly on the production and distribution of energy, that this century's monopolisation of energy by utilities threatens the health of our environment and the very life of our planet.
I. We, the Solar Guerrillas of this planet, therefore resolve to place energy made from sunshine, wind, and falling water on this planet's utility grids with or without permission from utilities or governments.
II. We resolve to share this energy with our neighbours without regard for financial compensation.
III. We further resolve that our renewable energy systems will be safe and will not harm utility workers, our neighbours, or our environment.

Tale of Three Cities
Last week a bit of publicly funded propaganda arrived in my mail box.
The one thing struck me in the ‘Budget Highlights 2008-2009’ was that the ACT Labor government is fond of trees. Indeed is seems to be the only tool in their climate change toolbox.
Here are the climate change dot points by town area.
Belconnen:
Additional tree plantings – Lake Ginninderra.
Canberra Central:
$0.267 million for Tree Replacement Program – Inner South and Inner North.
$0.250 million for Additional Tree Plantings at Lake Burley Griffin.
Gungahlin:
Additional tree plantings at Gungahlin.
Tuggeranong:
Additional tree plantings at Lake Tuggeranong.
Woden, Weston Creek and Molonglo:
$10.6 million for One Million Trees Initiative – Canberra International Arboretum and Gardens.
I’ve always said that renewable energy programs are a far better investment, than the knee jerk ‘plant trees’ response, for building a sustainable climate future.
Given the twists and turns in the Tuggeranong Power Station project, maybe it’s time for another approach.
Canberra hosts the Australian Federal Parliament. Lets look at the city that hosts the mother parliament; London.
The last Lord Mayor of London, Ken Livingston, set in motion a plan to make the city far most sustainable. The new Lord Mayor has undertaken to continue this drive.
What was the first thing that London did, it poached the guy that had the most foresight and experience with this kind of infrastructure redevelopment. They made Allan Jones, the energy services manager for Woking, an offer he couldn’t refuse. Over the last 20 years, he has nudged and lead the development and integration of Combined Heat and Power (CHP) systems and other efficient decentralized developments into the infrastructure of the English city.
Stuff about Woking and London.
Woking is a city of 60,000, a good match for the basic units of Canberra’s development, the towns.
This work doesn’t come cheap. Anyone who says fixing climate change will cost a household $200 a years in extra costs is dreaming, deluded or a con man.

Cycle, it's all cycles!
We’ve all seen the Atmospherics CO2 graph for the last few decades. It’s an upward trending line with an annual fluctuation. The uptrend is largely the result of the burning of coal & petroleum over the last 250 years. The annual fluctuation is caused by the photosynthesis/respiration/decay cycle of vegetation, the bulk of which is in the northern hemisphere.
Mauna Loa Carbon Dioxide
Ok, to stop the up trend, it pretty obvious what we need to do. Stop burn coal & petroleum! We need to shoehorn ourselves back into the annuals solar/geothermal energy budgets of the planet.
For some reason that’s beyond me, the knee jerk reaction seem to be to try to ‘freeze’ carbon out of the atmosphere using whatever mean is available. To shoehorn ourselves back into the annuals energy budgets of the planet we need to work with the carbom cycle, even accelerate it, not freeze within parts of it. This topic will be an assay in its own right, for the future. Stay tuned.

> One issue is how much GH gases you release, but more important is where the carbon (including embody energy) came from in the first place. Is a fire better that an electric light? Would the depend of if the electricity is solar or gas or oil or coal fired. Is the fire a wood fire or brickettes?

> I always ask, "where was that energy a year ago, 10 years ago, a hundred years and a thousand years ago?" Ultimately you're going to end up in one of four places. The sun, heat in the crust or below, the moon (tidal) or in a since mined crust deposit (I use this wording to cover exhaustible fossil fuels & radioactives).
>
> I'll leave you to work out witch 3 are exceptable and witch one isn't!
The initial response.
Hi there I'm still a newbie with lots to learn. So correct me if I am wrong you are saying condensed burning a 10 year old tree is more acceptable than condensed burning a 10 million year old tree and of the same ammount ?
I think the question was is the release greater at the power station than if every household was burning ?. There is simply no space on standard household blocks to have a huge array to produce their own solar energy to meet the same loads, that would also be the argument that appliances not just lights are just as inefficient as current solar technology :)
My reply, on why I think carbon is not all equal. History (source) counts.
The carbon in the tree is carbon that is in the carbon cycle. It moves through different parts of the biosphere over time. Moving between plants, animals, the atmosphere, the oceans and soils. Each of these five can be though of as a 'pool'. This carbon is constantly on the move. Part of the ongoing cycle of the biosphere and life. This carbon has fuelled human societies since we could rub two sticks together and this movement is generally fuelled by the sun.
Fossil carbon has been out of the above pools for ten if not hundreds of millions of years. When you burn fossil fuel you’re releasing 'new' carbon on the biosphere, and it usually ends up in the atmospheric or oceanic pools.
So when you burn carbon to make light (or movement or heat etc), it’s the history of that carbon that is important.
When it comes to removing carbon, it don't matter which carbon you remove.
How we farm, graze, forest and fish is important, but to a lesser degree. These processes determine how carbon is distributed between the five 'pools'. We need to move carbon to the plants, animals and the soils 'pools' from the atmospheric and oceanic 'pools'. The atmosphere and the oceans are so closely coupled in some ways they are just one 'pool'.
When I use the term solar, I'm referring to all sun powered systems, photovoltaic, thermal (dish & rheostat systems), biomass, wind and waves. Remember waves are driven by the wind. Wind in turn is driven by differential heating of the earth by the sun. You’re right, photovoltaic are still so poor on a system lifetime basis, that they are still effectively at the research & prototype stage. We got to start somewhere. Edison is said to have tested 10,000 configurations to get an appreciable one.
The reply about my thoughts
Thanks knoll. I never saw it that way, but oil has been referred to as
ancient sun energy or something like that. I would see it worse off
though if everyone started mass polluting from their homes don't you
think ? Thats why incinerators were banned, wasn't it. If incinerators
were banned that is a double standard for the industries then heh :)
Sorry i send this offlist so I don't bore the list with my ranting so
people don't get the wrong idea of me as i'm new :\
My second reply. Here I try to tease carbon out of other pollution issues. This case local ones.
Yep, oil has been referred to as ancient sun energy (coal too), the operative word is ancient. What this means is that the carbon is not in one of the biospheric carbon ‘pools’, but is in the geologic carbon ‘pool’.
There is normally very little movement between the biospheric carbon ‘pools’ and the geologic carbon ‘pool’. Some oil tars seeps to the surface here, some dead vegetation and animals sink to the bottom of a swamp, lake or sea and is buried there. The last 250 years ain’t normal.
The bans on incinerators, leaf burning etc are spot bans to stop local pollution hot spots. As with any activity, there are likely to be GH effects. There are two ways to look at leaf burning. You’re just releasing back to the air, carbon that was taken out last spring & summer. The other was is that you’re diverting carbon. You’re releasing carbon back to the air via near instant combustion instead of via slow decay, absorption into plants etc. You’re changing the distribution between the ‘pools’, at least in the short term.
I posted the comment, hoping they help people understand the cycle of life (particularly carbon) better.

Global Warming: the biggest event of the year?
From a Global warming prospective, I think the biggest event of the year has just occurred.
What is it, you may ask. The 17th National Congress of the Communist Party of China. Why do I think this?
Basically, the two lynch pins on turning Global warning around is China & India. There are other important players, like Russia, US, Australia, Canada, Brazil etc. But China & India are special. They are both huge emerging economies and members of the ‘Big Five’ coal nations.
The worst didn’t happen. The worst is that the ‘economics development at any cost’ faction could have gain complete ascendancy. There are socially conscience (anti-poverty) and environmental conscience factions that still hold some power in terms of numbers & positions held.
Basically I think emission global, can only start to decrease once BOTH Chinese and Indian governments think the likelihood of civil unrest & revolt caused climate chance are more likely than civil unrest & revolt caused by economic instability & poverty. Everyone else’s decreases in emissions will just be eaten up by China & India until this happens!

House locations are on the site, grouped by state.
This Ainslie house look very interesting. The TV grab says it’s water independent and grid connected. It aims to be energy positive in the summer and have some energy drawdown in the winter.
In Canberra, the open houses are on Sunday. On Saturday, there will be open days at several schools and an office building.

Permaculture: Doing things with feeling
Been reading the current edition of E. F. Schumacher’s 1973 classic “Small Is Beautiful”.
In chapter 3, “Resources for Industry”, I’ve just found the provoking paragraph.
I think this is the beat argument I ever seen for doing things with/by feeling and being entrepreneurial.
It’s interesting to read a pre global warning environmental book. One of the core factors in the current debate just isn’t there. Yet the core logic and directing is as current today as it was then, during the first oil shock.
Well worth the read.

In chapter 3, “Resources for Industry”, I’ve just found the provoking paragraph.
It is fashionable today to assume that any figures about the future are better than none. To produce figures about the unknown, the current method is to make a guess about something or other – called an “assumption” – and to derive an estimate from it by subtle calculation. The estimate is the presented as the result of scientific reasoning, something far superior to mere guesswork. This is a pernicious practice which can only lead to the most colossal planning errors, because it offers a bogus answer where, in fact, an entrepreneurial judgement is required.

Carbon: is Algae a solution?
Yesterday, there was a post on the treehugger site.
Its title is ‘Seambiotic: Algae That Clean Up and Put Out’.
I think this is the core statement of the article. It’s a great concept. In deed, it’s very close to how the biosphere disposes of carbon, via the death of phytoplankton as the Oceanic conveyor plunges down to the abyssal plain in the North Atlantic.
But it not a solution to carbon from coal fired power stations. We are still burning fossil carbon and releasing it into the carbon cycle.
When running the ruler over any solution, my rule of thumb is ‘follow the carbon’!

Trains and peak oil
A few weeks ago, at the start of the Difference of Opinion program titled 'Are We Running On Empty?', one of the panelist Professor Peter Newman commented about rural rail line closures.
Here is the whole transcript
PROFESSOR PETER NEWMAN:
My family have always tried to use rail first. It safer. Less people die in rail related accidents the road accidents. The big trucks used to carry wheat are dangerous and they damage the roads far more that cars.
These line closures are an ongoing process. At home they have been fighting a local closure since the Goss labor government.
Labor just don’t seem to understand that the last section of a rail line will generate the least money. That the freight carried will generate usage and money for all sections of line between there and its destination (usually Brisbane). The removal of a tributary means less flow at the mouth of a river.
So with peak oil and global warming, I think we need to go a step further. Once you decide to not close a line, you should be thinking of electofication. Current most country trains still use fossil fuels (diesel). We are still omitting new fossil carbon into the carbon cycle. With electricity, currently, you would still be powering trains with fossil fuels, either coal or petroleum gas. But, electricity is an energy transportation system, not an energy generation system. You can always convert the ultimate power sources over to alternative energy sources on an incremental basis.
An electrified rail system can ultimately be turned into a non fossil carbon emitting system!

PROFESSOR PETER NEWMAN:
…But we are still building suburbs as though cheap oil is going to be around for the next 50 years. We're still - we're about to close down the wheat lines, the rail lines that go out to our wheat-belt areas, as though trucking will be able to use fuel that's as cheap as it was in the last 50 years. These stupid things have got to stop. We have to face up to a future that is much more constrained. It's not going to run out, right, but it will be seriously more expensive and we're not all going to be able to have access to it. A lot of poorer people will really suffer.

These line closures are an ongoing process. At home they have been fighting a local closure since the Goss labor government.
Labor just don’t seem to understand that the last section of a rail line will generate the least money. That the freight carried will generate usage and money for all sections of line between there and its destination (usually Brisbane). The removal of a tributary means less flow at the mouth of a river.
So with peak oil and global warming, I think we need to go a step further. Once you decide to not close a line, you should be thinking of electofication. Current most country trains still use fossil fuels (diesel). We are still omitting new fossil carbon into the carbon cycle. With electricity, currently, you would still be powering trains with fossil fuels, either coal or petroleum gas. But, electricity is an energy transportation system, not an energy generation system. You can always convert the ultimate power sources over to alternative energy sources on an incremental basis.
An electrified rail system can ultimately be turned into a non fossil carbon emitting system!
