What are biofuels and where do they come from? This video presents algae biodiesel as a possible future source of renewable carbon neutral energy. (Background info for the first two minutes) If you like, please hit the happy thumb! by Angus R. Chen Special thanks to the Oberlin College Biology Department and the Bonner Center for Service and Learning Also thanks to some of the pioneers for this type of video format, people like Jorge Cham and Henry Reich over at MinutePhysics who do this kind of thing far better than me. A couple of things I didn’t mention: the reason why biofuels are considered carbon neutral is because even though they release carbon dioxide back into the atmosphere when burned, they sequester it as biomass while they’re growing. So they’re not actually adding to the sum of atmospheric carbon – it all is supposed to come out close to zero.
