$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."
If you plated the entire US with solar panels, using the most efficient panels we currently know how to make, and you assume that there is no cloud cover or other weather obscuring the sun at any point during the year... you still wouldn't have a significant fraction of the power used by the entire US.
Unless you have some calculations to back that up, I call BS. According to http://rredc.nrel.gov/tidbits.html, "Every day, more energy falls on the U.S. than we use in an entire year." Since solar panels are more than 3% efficient (quick googling tells us the most advanced ones are over 35%), you fail it. Saying this is not possible is simply foolish, and it undermines your larger argument of whether it is advisable.
