Virgin Atlantic unveiled plans Monday to try to make its commercial flights more eco-friendly. In a partnership with Boeing and GE Aviation, Virgin Atlantic will attempt to be the first airline to fly a commercial jet on biofuel. The company's jumbo jet -- a Boeing 747 -- will take off in London and land in Amsterdam, making the 20 minute flight on an experimental fuel that is 20% biofuel and 80% conventional.

Sources at Virgin won't reveal which company is supplying the fuel, or just exactly how it's made. A spokesperson for the airline did say that it's definitely not made from palm oil, but instead from a "very sustainable source." Whatever it is, jet engines won't have to be modified to burn it -- which ought to make it pretty marketable.

Owner of the Virgin empire, Richard Branson, announced back in 2006 that his company would donate $3 billion in profits to fight global warming over the next 10 years. Not only that, but he's offering $25 million to someone who can create a commercially viable method to remove anthropogenic CO2 from the atmosphere. That reminds me, I need to get back to work on that carbon vacuum.
