New Generator Converts Heat and Solar Power Into Electricity

Through a process known as thermionic conversion, heat energy — such as light from the sun or heat from burned fossil fuels — can be converted into electricity with very high efficiency.

Because of its promise, researchers have been trying for more than half a century to develop a practical thermionic generator, with little luck. That luck may soon change, thanks to a new design — dubbed a thermoelectronic generator — described in AIP Publishing’s Journal of Renewable and Sustainable Energy (JRSE).
