Looks great, I'm looking forward to the day when these will power electric cars :3 (I'm also just a bit biased towards these instead of batteries for refill/recharge ;) don't mind me)

I heard quite a long time ago that Mazda was working on a rotary engine that could burn either gasoline or hydrogen. I thought THAT was one cool concept. There are problems to overcome with storage, but I still think hydrogen is the answer, whether it drives a fuel cell like this or combusts in a mechanical engine. Existing gas stations could be upgraded to dispense hydrogen. So the infrastructure is nearly in place and the current fuel companies would feel less threatened. I dunno. I guess I'm a dreamer.
