Well, crude oil is just old algae anyway.
Oh, its real, and viable. I have been following algae biodiesel for at least 5 years now, and I whole-heartedly support it. It is the only “green” energy I support, not because I’m an econut, but because its a brilliant idea, I think its viable, can use existing technology and infrastructure, doesn’t need subsidies, and does not require either lots of land, nor crop land if you do it right. Plus, the waste can be either burnt in a coal plant, be used as fertilizer, or even used for feed. Its win, win, win.
