On Seeking Consensus: A New Project on the Energy Collective

Robert a team from your university were amazed by the potential base load supply available from the ocean with OTEC. To some extent I agree that the current conventional approach, which relies on massive cold water pipes, is a technological dead end but that is not the only way. A deep water condenser, or heat pipe design would produce the same atmospheric warming hiatus as is currently being experienced due to increased trade winds, whether or not you used the system to produce power. Geoengineering if you like, but it also can produces between 14 and 30 TW of primary energy even as it mitigates damage from sea level rise and storm surge. Looking at the problem through the filter of an energy professional is not necessarlily the only, let alone the best, approach the problem.

On Seeking Consensus: A New Project on the Energy Collective

"Seeking Consensus", I hardly think that is the case when the third largest renewable energy option, the largest constant renewable option and the only one with the demonstrated capacity to make an impact on the global warming problem is not amongst the mix for consideration.

On Energy and the Environment

The ocean and the atmosphere will eventually equilbrate but the Levitus study makes clear this won't happen anytime soon otherwise we would be toast already. In the meantime it is better that .09C has been accumualting in the ocean rather than 36C in the atmosphere and the climate pause punctuates this point.

Your point on evaporation is also questionable. Kevin Trenberth points out that the water holding capacity of air increases by about 7% for every 1°C warming. This vapour is a strong greenhouse gas and produces strong preciptation events. Again this 1C at the surface would be better as .00somethnig between 500 and 1000 meters.

If we replace fossil fuels with OTEC power over the next century atmospheric CO2 levels will also have a chance to decline.

On Energy and the Environment

Rick all I can do is point you to the diagram that accompanied this article.

If the second law of thermodynamics in wrong, then I am as well. The oceans are the largest warm and cold heat sinks on the planet. The hot sink is causing no end of problems while the cold is available to us with little potential for damage in the movement of heat there. In that process however we can extract work.

I realize lots of us care about the problem. We just aren't getting very far with our efforts to do anything about it.

On The Burning Question: Who is Up to the Climate Challenge?

Alistair, the latest study suggests unusually strong trade winds have pushed surface ocean heat into deeper water leading to the perceived atmospheric warming pause of the past fifteen years. We can replicate this effect with OTEC meaning we can obtain the energy we need at the same time as we effectively geoengineer our way to an inhabitable planet.

I hope to have a new post along this line shortly.

I have no problem with anyone reordering the list, it is just what came to my mind.

I agree completely we need to be talking outside this forum but it is one of the few availabe to me. It drives me crazy that my government - Canada - is about to pay some ad agency $22 million dollars to promote the "benefits" of oilsands abroad.For those of us without that kind of money but who nevertheless believe there is a silver bullet, failing to do everything in our power to get the word out is to do the technology and mankind a disservice.

On Climatologist: When Souped-Up Ocean Warming Ends, Global Temperatures Look Set To Rise Rapidly

This study ought to be the blueprint for addressing climate change. You can produce as much renewable energy as we currently derive from fossil fuels by moving surface heat into deep water with ocean thermal energy conversion. The coefficient of expansion of ocean water is half that of the tropical surface at a depth of 1000 meters and you would be sapping the power of tropical storms that move heat towards the poles. The oceans have a tremendous capacity to absorb this heat as to a depth of 2000 meters they have only warmed.09C in half a century and they are on average close to twice that depth. It seems to me if we do not learn from natural analogies like this our climate/energy efforts will be costly and ultimately feckless.

On Limits to Growth: At Our Doorstep, But not Recognized

The problem is the connection with debt.

Michael Hudson's video may be instructive in this regard.

"The oligarchs would rather annul the bottom 90 percent's right to live than to annual the debts that are due to them."

It wasn't always that way and need not necessarily be that way in future.

"If you owe the bank $100 that's your problem. If you owe the bank $100 million, that's the bank's problem," J. Paul Getty.

If a 100 million owe the bank a dollar and can't pay the bank is in no less difficulty.

On What Wood Smoke has Taught Me About Fighting Climate Change

Severin, research is the answer and Nature is providing the analogies as to how the climate problem can be beaten. It takes time however for new technologies to be cost competitive and a great deal of capital to make a dint in the market. The innovation "Valley of Death" is a chasm which market forces alone don't appear to be sufficient to bridge?

On Germany's Energiewende Troubles Prove That Renewable Energy Has Failed. And Other Strange Ideas

Robert, Nature cannot be fooled but we are not paying attention to how she is reacting to climate change either.

From March 2010 to March 2011 NASA reports that sea levels declined by about 6 mm as water was transferred from the oceans to the land.

From 1998 to the present there was a perceived decline in the increase in recorded world temperatures compared to the 15 year period from 1990-2005, which was attributed mainly to an increase in uptake of heat by deeper ocean waters.

We can replicate both of these responses concurrently to producing significant quanties of renewable energy.

On A Forecast of Our Energy Future; Why Common Solutions Don’t Work

Rick, the last time it happened, parts of Canada turned to the Social Credit philosophy of  C. H. Douglas, whose policies were designed to disperse economic and political power to individuals. Oddly enough where this movement took strongest hold was in the provinces of Alberta and British Columbia, which today are betting it all on their fossil fuel reserves. Alberta went so far as to issue "Prosperity Certificates" to its citizens to try and get its economy moving but the Supreme Court of Canada squelched the move by claiming the federal government alone was authorized to issue currency.

Seems to me a climate currency would be difficult proposition to refute in the light of current circumstances.

On When Will the Obama Administration Possibly Approve the Keystone XL Pipeline?

John SAGD isn't any better considering the carbon emissions. I left Alberta in 79 for beautiful British Columbia to escape the petro lunacy but it turns out I didn't. Now they want to threaten our shoreline with spills and erosion from sea level rise and today they shut down our local ski hill due to lack of snow.

Not unrelated I think.

Believe me, more and more are becoming sick of this situation and a day of reckoning isn't that far off.

John, Canadians other options to placing their Oil Sands crudes into world markets face no less difficulties.
