ABSTRACT:
A practical solar-thermal-electric power plant can be built at a reasonable cost with available materials and conventional engineering design techniques. Fields of steerable mirrors concentrate the reflected sunlight on hot receptors behind heat-conserving windows on short towers. The

absorbed heat from the hot receptors is carried by heat exchange fluids through pipes to a central station power plant containing heat exchangers to preheat and boil water and to superheat steam, and a conventional turbine and electrical generator. A 100-megawatt power plant would be supplied from 1100 towers of 35 meters height, each tower receptor illuminated by a hexagonal field of 50 meters by 48 meters. Each field has 312 mirrors of 2 square meters surface each. The capital cost in dollars per megawatt-hour of annual production has been reduced by unique heliostat field geometry, mirror construction, high transmission window, high absorption cavity, and optimum utilization of available heat at different temperatures in the thermodynamic cycle.
