Hydrogen Fuel Cell

[BrianG]

While it is kinda neat, I think I will wait a while before I even think about trying it. It's kinda hefty for the power you get. I would rather just use a lipo sized for what I need; would be cheaper, lighter, and simpler.

kraegar, might look neat at first sight, but fuel cells make no sense what so ever. Hydrogen production is a loss through and through, the fuel cells are heavy and the more power you want to extract from them, the less efficiency they are, hydrogen storage is very problematic, the atoms literally go straight through the storage medium. There is more hydrogen in a mass of gasoline than liquid hydrogen, it is safer, and is more economical, both cost and environmentally.

I can see hydrogen being a big plus if we had a more efficient electrolysis method (although there are many scientists that claim order of magnitude more efficient process, high frequencies, high voltages, that's another story), couple that to a mini bloom box, which are small already, find a good storage material to prevent leaking, then throw in a small 50+C lipo power pack.
