Terrestrial solar power system based on Cs-Ba thermionic converter

A new concept of terrestrial, environmentally friendly solar cogeneration system is described. Power generation is accomplished by a cascaded system with the high temperature stage being a Cs-Ba thermionic converter. Its heating is accomplished by a two-stage solar concentrator with a mirror and focon. Thermal efficiency of such a system is close to 100% because all the heat supplied to the heat receiver is utilized.
