Optical power or radiation transfers power at 10 to 100 times the power per area compared to conduction and convection of combustion and nuclear power plants. The 3000-5000K SunCell® plasma emits radiation at a power density of 4.6 to 35 MW/m2, corresponding to an extraordinary 150 kW to 1.14 MW, respectively, transmitted through an 8-inch diameter window. With light recycling, the transmitted radiation incident a CPV DRA can be converted from optical to electrical power at over 50% efficiency enabling extraordinary performance, logistics, low capital cost, and projected electricity costs of less than $0.001/kWh.
The thickness of the SunCell’s® refractory liner was increased to allow the internal temperature to reach 3000K in regions. The refractory lined reaction cell chamber serves as a blackbody cavity that equilibrates to reach a uniform temperature to serve as a blackbody radiator of a controlled temperature selected to maximize the conversion efficiency of the DRA that exploits light recycling to produce electricity at high efficiency.
*The camera attenuation was set at the maximum.
