$25M Bounty Offered for Global Warming Fix

SaDan writes "Richard Branson is offering $25M as a bounty for a fix to global warming. The person or organization that can devise a method to remove at least a billion tons of carbon dioxide a year from the atmosphere will be able to claim the bounty. There are a few catches, of course. There can't be any negative impact on the environment, and the payment will come in chunks. A 5 million dollar payout will be paid when the system is put into place with the remainder of the bounty to be paid after 10 years of continuous use."

    How much carbon dioxide does a single tree consume in a year of respiration and how many trees could be planted for $25 million?

    Either that or find a way to build large scale air scrubbers that simulate plant respiration (stripping the carbon atom off a CO2 molecule and releasing O2), then compress the pure carbon into bricks for use in industry. If it could be done cheaply enough it might not just be eco-friendly, but profitable as well, with the $25 million payment as a bonus.

      Trees alone won't solve the problem for the same reason they aren't solving the problem now: people keep cutting them down.

      We cannot possible reserve all of the arable land necessary to plant enough trees to scrub the carbon dioxide we are throwing into the atmosphere, because we need that land for other purposes. As the human population continues to grow, the need for developed land increases. This trend is not likely to reverse itself.

      A carbon scrubbing solution that would actually be workable would have to take up much less space than trees would to produce the same result.

      Warning: back-of-envelope calculations follow. The bond energy of the two carbon-oxygen double bonds in carbon dioxide is about 374 kilocalories per mole of carbon dioxide. At 44 grams CO2 to a mole, a billion tons of carbon dioxide (using 1000kg=ton) is on the order of 2x10^13 moles. This would require 3x10^13 megajoules of energy, which to provide in one year (31556926 seconds) would demand 950 gigawatts of power, which will undoubtedly require more than 25 million dollars to generate. This assumes perfect efficiency in the process, of course, and does not factor in any carbon dioxide released in the generation of that much power.

      The reason this process works so well in plants is that frankly, that's not how it works in plants at all. While photosynthesis involves the net breakdown of carbon dioxide and water to form oxygen and glucose, it's a complex set of separate, but connected reactions, rather than just using sunlight to blast oxygen atoms off carbon dioxide. For instance, the oxygen produced doesn't come from carbon dioxide- it comes from water split by sunlight, with the help of an enzyme. The carbon dioxide that enters plants is never actually split apart- it's simply fixed into an organic molecule, and used to generate a glucose precursor. Breaking down carbon dioxide to its component elements is simply too energy intensive.

      I suppose that's an idea though- if there were a catalyst that could fix carbon dioxide into an organic molecule, and do so at reasonable conditions of temperature and pressure, it might provide a useful way of recycling carbon. For example, if you could react carbon dioxide with methane to produce acetic acid, you could pull two greenhouse gases out of the atmosphere and use them to make an industrial product (and one which could be conceivably then be used as a feedstock for plastics and fuels). Currently, this process uses carbon monoxide and methanol (made from steam reforming of methane, actually), in the presence of a metal catalyst- it seems like it could be done with CO2 and methane instead. Even if the economics might not be as favorable, the benefit in sequestering greenhouse gases might be worth it.

This is assuming the current wasteful method of not reprocessing fuel. Waste reprocessing, which itself generates energy, would increase the fuel utility by a factor of 10, and would eliminate nuclear waste entirely. In short, we have enough fuel to run fission reactors in place of all the conventional CO2 generating power plants for over 1000 years. Fuel is not the problem. The problem is enviro/peacenik whackos who conflate nuclear weapons with nuclear power and tar them all with the same brush. People like that create a groundswell of popular ignorance that leads to things like Jimmy Carter signing an executive order banning the building of ALL breeder reactors. A particular type of breeder reactor is used to make weapons-grade plutonium. Fuel reprocessing breeder reactors, however, create an inseperable mix of plutonium that is utterly unusable as a weapon. Now why Carter, a trained nuclear engineer, would ban all breeder reactors is a question with only two possible answers: a) the man's an idiot and faked his way through school, or b) he was making a purely symbolic, political gesture. The issue of nuclear power has been thoroughly politicized, to the point where it's hardly about science anymore.

    The best things here would be a natural energy source. All energy sources are natural, from water running downhill, to hydrocarbons combusting, to atoms splitting. You can't apply a "back to nature" philosophy to the production of energy!
