This report was written by A. Der Minassians et. al. of UC Berkley. It measures the feasibility of solar thermal systems used for electric power generation, which could compete for price parity with other sources of electricity. The paper claims that when using only low-cost materials and manufacturing processes it is still possible to design a solar thermal electric system. The collectors should operate at a medium temperature of 125C to 150C. The design the researches focused on is a free-piston Stirling engine, which they determine has the best cost to efficiency and use ration for capital costs.
