Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A Johnson thermoelectric energy converter or JTEC is a type of solid-state heat engine that relies on the photodecomposition and recombination of hydrogen in a fuel cell using an approximate Ericsson cycle. It was invented by Lonnie Johnson and is under investigation as a viable alternative to conventional photovoltaic cells. Johnson claims the converter exhibits an energy conversion efficiency of as much as 60% compared to 30% efficiency typical of the best photovoltaic cells, although this is a theoretical level based on comparison with a Carnot cycle, and assuming a temperature gradient of 600C. It was originally proposed for funding to the Office of Naval Research, but was refused. Johnson obtained later funding by framing the engine as a hydrogen fuel cell. Currently Johnson is collaborating with PARC on development of the engine.
