Here, you'll find an article about what looks to me, the up and coming new energy source for the green people, and well, for all of us. It was on 60 minutes, you could probably youtube it if interested. But yeah, if I remember correctly, its a fuel cell. On one side, oxygen enters. On the other side, fuel enters. This, along with some other shit going on, creates an electrical charge. It needs a ridiculously less amount of fuel then standard fuel energy. So yeah, discuss.
