Direct Conversion of Heat to Electricity 2008-21-0049
The prime candidate for direct conversion from heat to electricity has historically been thermoelectric energy conversion. More recently, advances in thermophotovoltaic systems render them potentially interesting. Neither class of systems is used in automobiles to any significant extent today, and neither class of systems is poised on the brink of a large-scale adoption. In this paper, the characteristics of these types of energy conversion are discussed, with special emphasis on their utility in automobiles.
