Abstract:
1. A method of generating electricity under a Rankine thermodynamic cycle, the method comprising: a) providing a solar concentrator electric plant; b) generating saturated water vapor at a pressure of at least 96 bar utilizing a two-dimensional solar concentrator from water; c) subsequent to step b) generating overheated water vapor utilizing a three-dimensional concentrator from the saturated water vapor; d) subsequent to step c) generating electricity using a steam turbine from the overheated water vapor; e) in a first operating condition, flowing the water in a continuous cycle through a piping system so as to flow in sequence through the two-dimensional solar concentrator, the three-dimensional solar concentrator, the turbine and back to the two-dimensional solar concentrator; and f) in a second operating condition, flowing the water in a continuous cycle through a piping system so as to flow in sequence through the two-dimensional solar concentrator, through a back up fossil fuel generator adapted to provide backup heat to the water, through the turbine, and back to the two-dimensional solar concentrator, bypassing the three-dimensional solar collector.
