We have an operating Stirling engine at 2kW, intended for solar thermal and waste heat thermal inputs. We have hit 16.5% thermal to electrical conversion efficiency at 220C hot side temperature, 10C cold side. We are finalizing our 2.5kW unit design, and hope to have 10 pilot units beginning installation by early 2011.

Pricing is to be determined, based on the final 2.5kW design and contract manufacturer bids.

For point of reference, I was quoted a price of $40,000 for the ST-5 unit from their supplier in Japan, which is the only source into the US. for roughly 3 kW output, this is rather pricy.

Infinity turbine organic rankine cycle units rated at 10 kW are billed at $20,000, although you need heat exchangers to heat a fluid.

for larger capacity systems, the Turboden units from Italy may offer some advantage…

You should be able to buy the WhisperGen through http://www.whispergen.com, and ask for a dealer nearest you.

I don’t know that it can be easily modified for solar, as that would probably involve a different heater design; something that can receive incoming solar radiation in an efficient way. But I’m sure there is a way to do it, starting with a different heater design, probably similar to Stirling Energy Systems design (http://www.stirlingenergy.com)
