<x-charset ISO-8859-1>A dish stirling solar system is similar. No exotic chemicals used in the manufacture as compared to PV, No thermal pollution (the sun is gonna shine anyway, so the same heat load has to go somewhere) They can be air cooled, or at least coolant in a sealed loop. Also solar thermal engine conversion efficiency is higher (not that any efficiency but watts/$ matters anyway) BSR, a german company, has a solar powered water pump with no PV and no tracking required.
