I applaud your sentiment, viz: biological sequestration of carbon, but the reason we have an incredible excess of CO2 is that extant biological systems cannot absorb or sequester the Carbon emitted. To further exacerbate the problem, as the ocean warms it will not retain the CO2 it has sequestered. There is as much as 800 years in the lag. Then the CO2 comes out of the planet's oceans and into the air. I too favor biological sequestration but realistically see it as a futile hope without some serious bioengineering and serious gene modifications tailored to our situation, as well as preservation of the biomass doing the sequestering. What I really really favor is an economical and efficient means of splitting the O-C-O bond and the capture of the Carbon and its fixing into a pure form fixed and manageable form. Such Carbon forms as buckyballs, buckytubes, buckysheets, carbon fibers, graphite or soot or diamond to suggest some of the elemental forms) or perhaps sodium or calcium carbonates or other carbon solid compounds, even long lasting tree roots or trunks. The amount needing removal from the air is at least 80 ppm, though I would hope more would be extracted, since the IPCC and others are thinking of doubling the current volume in the air. (Imagine 760 ppm or more, say 1%, at 1000 ppm.) Surely you see that as a potential problem? Current ocean warming thwarts even the biological response of the ocean, since warm water will not hold as much CO2 as cold water, and in fact a possible additional 80+ ppm or more is likely to be reintroduced into the air as the air temp warms 4 C. or so. It takes time to warm the deeper waters -- at least 400 to 800 years. So, I think we will see CO2 levels rise greatly even after the use of fossil fuels stops, simply because of the warming our anthropogenic use of fossil fuels has already initiated. I have posted here on Xomba about these things -- even the fact that you and I exhale enough CO2 in a year to create a diamond of nearly one cubic foot size, each. As a rough yardstick, human exhalations produce carbon on the scale of roughly 6.x billion cubic feet per year. All from the Carbon in our food. So that said. We will have to build machines to suck the CO2 out of the air and sequester it. And we will have to build them and operate them using non fossil energy sources. Imagined making twinklies cup cakes and zwingers (yeah spelled different not to offend the mfgrs.) out of the huge amount of C we pull out of the air. It is not unreasonable to use deep, deep ocean sequestration of CO2, but it tales engineering on war-footing scale. As I have said, public hangings for politicians and corporate masters responsible might be the quickest way to reverse attitudes. Population control through engineered pandemics is also an attractive 'concept.' Sure, we might do it a better way. Suggestions? Time's running out for the population we have. On the burning of salt water! I like the idea and hope to see the various labs work out the physics. I remember Cold Fusion, not with too much disappointment, since I think and hope that and this process leads into new physics, and turns out to suck energy from places like the zero point or the vacuum of quantum physics. I also hope the inventor succeeds in his cancer treatment and own Cancer treatment application and that the trials at the Anderson Center in Houston demonstrates a successful outcome for the treatment -- no matter what "efficiency" is accomplished in the cancer treatment phase. Dr. Roy feel this is the real thing -- and I hope he is right and that oil and need of oil goes away. It is great to use oil for lubricants and food, but not to burn to CO2 and force the heating of the planet.

I understand the allusion. However, I am warped to think of it differently. Alchemy turned into the "science" of chemistry, and if you recall your lab manuals they had little secrets known since the days of the mystical chemist. Anyhows, the use of a similar approach with RF and Liquid CO2 doped with what, might yield a nice way to gather the carbon and prepare it for sequestration. What goes beyond the water idea? lots of different approaches: http://www.greencarcongress.com/2007/04/researchers_dev.html So we cool to liquid and use platinum or palladium in the RF excitement? Use alchemical allusions...
