Virgin announces new contest to combat greenhouse gases

Richard Brandon of the Virgin Group and Al Gore have announced a new challenge to scientists and inventors.
"The Virgin Earth Challenge is a prize of $25m for whoever can demonstrate to the judges' satisfaction a commercially viable design which results in the removal of anthropogenic, atmospheric greenhouse gases so as to contribute materially to the stability of Earth’s climate. "
Good to see that some people are putting up the money to encourage people to work on this serious problem. There's nothing like $25 million to make a lot of people try to accomplish something!
