Details of how the unit generates power were quite interesting to me. I have always found the Sterling engines to be fascinating pieces, some of which are able to run solely on the difference between the heat from your hand and the surrounding air. By the way, if you have not already read the article or deduced from my comments thus far, the MCHP, as they are referring to it as, uses a Sterling external combustion engine for power generation. I don't see any reason the same type of technology couldn't be used to charge your electric car using your home furnace in the future. Supercharge your home furnace anybody?
