Anyone watch Glenn Beck?
Last night he had Richard Branson on for an interview. At one point, the discussion turned to global warming/climate change and the need to replace fossil fuels with something less polluting. Branson said that by the end of next year, 2008, he and his partners (Boeing, GE turbine engines, others) will fly a jet aircraft that produces zero carbon dioxide emissions.
He didn't mention the type of fuel that will be used, but he alluded to a sugar/corn ethanol type fuel.
