Re:I sent this off to the author (re ethanol) (Score 1)

I don't know much about this, but, I was wondering about a closed system, whereby, if you had a fuel cell in your laptop, and plugged it in, some electricity could be used to reverse the process. That is, take the water and break it back down to hydrogen and oxygen, much like a car battery, recharge to (somewhat) original charged state. That way, it would last even longer, refills would be a different sort, and as a business model, how about the car battery. Any thoughts on possible feasibility?
