Branson's billions putting brains to work for the earth

Richard Branson's investments in biofuels were welcome but not exciting, as biofuels are marginal at best (and environmental suicide via politics at worst).

With the Virgin Earth Challenge (and some instruction from Al Gore?), Branson's money is working smarter. Very very cool.

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.
