Many thermal energy conversion devices, such as thermoelectric, AMTEC and Stirling converters developed for space applications, also have terrestrial uses. Rather than use radioisotopes as a heat, a combustion flame can be used. Con sider a converter producing 100 W(e) with a 15% thermal to electric conversion efficiency designed to produce power continuously for one year.
