New production of solar thermal dishes: Phoenix-based Stirling Energy Systems Inc. and Schuff Steel Co. unveiled a prototype generator that could bring the cost of solar electricity down to 5 cents to 6 cents a kilowatt. .. Arizona Public Service Co., which is under an Arizona Corporation Commission mandate to generate 1.1 percent of its electricity through renewable resources by 2007, has agreed to buy 10 of the units next year. Southern Nevada Water Authority wants 40. " Sandia has ordered a number of them this year. They are 38-foot dishes with a Stirling engine, each generating 25 Kw.
"the Stirling units use no water, in contrast to so-called solar trough generators that use the sun's energy to produce steam to turn turbine generators. " Prototype units cost $300,000 each. "Stirling believes it can bring the cost down to about $25,000 per unit if they are mass-produced. That would make them competitive with conventional power plants, Liden said. " 9:38:17 AM
