it would be interesting to know how that project is going. That one and was it whispergen? Made a lot of headline 3 or 4 years ago. So we are talking apples and apples the 35 percent number is supposed to be the amount of energy converted to electricity? Or the electricity plus recovered heat added together? I ask because you see the 80 percent claim sometimes and that is what they do and it kind of fudges the numbers. Complexity rears its head there again since those high temps would mean exotic materials, aerospace level machining, high cost etc. Those high temp stirlings were what I had in mind when I talked about cheap solar knocking a lot of wind out of the sails of competing technologies.

Check out this 1kw, 24kWHr per day stirling generator with 35% thermal efficiency. But that is with a 2000C/4000F flame.
