Bloom Energy looks to be a very interesting company. They make natural gas powered fuel cells based on a solid oxide electrolyte. The website has a datasheet that shows the output capability of 100 kW. This unit seems to be for commercial application. It would be interesting to see a residential unit provide heat, hot water, and electricity as a replacement for present heating (HVAC)systems. Does anyone know if this is particle with this type of technology? I would love to outfit my home with a 3-5 kW unit as a backup power system.
