Futurology

Honestly, this is probably the best utility out of FCEB I've seen so far. It was always a dead-end for cars, but for short-term portable uses, this is great. There's actually a HUGE industry around portable butane that could be replaced with something like this.

Recreational, Construction, Culinary, Aviation...imagine replacing all of that with this as a solution, and you've got something. We'd obviously need to see some specs to see if it's possible. It's not going to make as much money as millions of cars on the road, but perhaps useful enough it will get uptake.
