    ya know, a more efficient use of the heat would be a steam turbine generator.

    don't know what MPG is, probly low 20s

    The cool thing about thermopiles is that they can be used anywhere. I just wish they were more efficient. maybe i will just get a solar panel to trickle charge my batteries. Wont be able to run my house, but maybe a small heater for a day or two if power goes out in the winter. I still like thermocouples, you just have to remember that 5% is better than 0%

    Ever heard of a tri-generation plant?

    Trigeneration or combined cooling, heat and power (CCHP) refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a fuel or a solar heat collector.

    I have heard of methods of salvaging heat from waste water to heat water for bathing, using cross-flow heat exchangers and small heat pumps.

    Had wondered if the same thing might be done with the hot air exhausted from a clothes drier, preheating dry incoming air, and maybe use a heat pump to salvage even more heat. Sounds a bit complicated, but I wonder about the gains in efficiency.
