Feasibility Study
We must go through a basic feasibility study to understand the importance and potential of solar concentrator power. First, we are considering solar concentrators for solar electric power. While there are many solar electric system options available, from photovoltaics and stirling engines to Rankine cycle low temperature electrical generators, we believe that the boundary layer turbine with solar concentrators is the lowest cost, most ecological, and simplest to manufacture.
Consider these basic facts relevant to power output and cost:
- Solar insolation is about 1000 W/square meter
- Considering cloud cover and day/night cycles, a place like Missouri gets 6 kWhr/square meter/day of insolation throughout the year, on [average.http://rredc.nrel.gov/solar/old_data/nsrdb/redbook/sum2/03947.txt]

Stirling Energy Systems utility solar - 20-year purchase agreement between Southern California Edison and Stirling Energy Systems, Inc. will result in 20,000+ dish array covering 4,500 acres capable of generating 500 MW, at a cost competitive to grid power. 37 foot diameter dishes. Each dish yields 25 kW. Nice. pi*18^2= 1074 sq feet, or exactly 100 square meters. 25% efficiency for the most advanced Stirling engine.
This is 100 kW/acre. Our calculations indicate 4 mW/acre, at 5%, 200 kW/acre. 50% fill factor, 100 kW/acre.
