http://www.homemadepowerplant.com/?hop=adonpub You can produce electric power from the sun with a solar powered sterling engine. Four times more efficient than conventional photovoltaics, PV or solar panels, and inexpensive to build, solar powered sterling engines are expected to be produced in large numbers in the near future. The small metal reflector focus the sun’s light energy on a special hydrogen filled tube. The resulting rapid heating and cooling of the gas taking place inside the tube runs the sterling engine which in turn can be connected to an electric generator to effectively produce electricity freely, cleanly and efficiently.
