<title>The Tower Reflector As An Alternate To The Tower Boiler Concept For A Central Receiver Solar Thermal Electric Conversion Plant</title>

Abstract

We describe a second generation central receiver solar thermal power conversion system that may offer more cost effective plant operation than plants presently under study for early POCE development.It is, however, technologically more risky.Our concept uses formed focusing heliostats more extensively, secondary reflection to a boiler at ground level, a flux concentrator at the boiler entrance, transpiration cooling of the boiler heat exchanger, and high energy density storage devices to smooth plant output. We report tests of some of the critical subcomponents in an actual intense solar environment. Finally, we summarize the potential system advantages for each element of the second generation plant.
