"The Stirling engine makes solar power so much more efficiently than photovoltaic solar cells can," said Robert Liden, chief administrative officer at Stirling Energy Systems Inc. (Phoenix).
If the project succeeds, the DOE predicts that by 2011, Stirling solar-dish farms could be delivering electricity to the grid at costs comparable to traditional electricity sources, thereby reducing the U.S. need for foreign sources of fossil fuels.
Right now about 20 EEs, including more than a dozen from Stirling Energy Systems, are working full time at Sandia to create the electrical-control systems to manage these sunshine stations.
Power Chips will deliver up to 70-80% of the maximum (Carnot) theoretical efficiency for heat pumps (conventional power generation equipment operates at up to 40% Carnot efficiency).
This tiny MEMS thermoacoustic generator converts heat into electricity. The source of heat can be solar radiation, combustible fuel, even body heat. It requires no maintenance and is cost competitive with all existing power generation equipment. (< $0.10/Watt)
same or less than the peak rates paid today — or "about 6.5 cents per kilowatt-hour during peak periods,

there may be a 1kw ZPE device by the end of next year, operating on principles not completely understood.

Exactly. correct me if I'm wrong, but nuclear waste is "recycled" into nuclear warheads, right?
But, nuclear waste is just that: nuclear waste. Nobody wants it in their back yard. Look at the nuclear waste spread out over south western Russia at Chernobyl, and the rest of the world for that matter.
