Thermoelectric energy conversion is a solid-state technology that is environmentally friendly. One of the more promising ‘down-to-earth’ applications lies in waste-heat recovery in cars.”Tritt said more than 60 percent of the energy that goes into an automotive combustion cycle is lost, primarily to waste heat through the exhaust or radiator system.“Even at the current efficiencies of thermoelectric devices, 7 to 8 percent, more than 1.5 billion gallons of diesel could be saved each year

For this special report, PM crunched the numbers on the actual costs and performance of each major alternative fuel. Before we can debate national energy policy--or even decide which petroleum substitutes might make sense for our personal vehicles--we need to know how these things stack up in the real world.
