Solar Dish Engine
Sunlight is concentrated through the use of a sun-tracking parabolic dish,(similar to a satelite dish),and focused into an aperture to generate electricity. SDE's are currently the most efficient sunlight to electricity technology. (approx.31%) Utilizing a Sterling engine,SES, Lockheed-Martin and the D.O.E. are currently testing these for use in utility-scale solar farms,but I envision single,stand-alone,25KW units meeting many rural and urban applications very nicely, (and lucridably.)
