Re: Fuel cells
The residential unit looks very promising--an alternative to noisy backup generators for homes with access to natural gas pipelines. In severe situations, like earthquakes, when gas lines might fail, an auxiliary tank might be an accessory. I wonder what the consumption rate is?
Of course, one would need something bigger than 1 kilowatt for a house, and smaller than the 250 kilowatt generator they also mention. Maybe 20 to 30 kilowatts?
I also see a future for computer APUs based on this technology. Judging from the picture on Ballard's site, this has occurred to them as well.
