Hi Scott, Even though they use unheated noble gases circulated briskly through much larger geometry with less suppression you are correct their method exploits the same "environment" of
Rapid Variations in suppression levels. They accumulate energy with what they term a "lamb pinch" (rather than chemical reaction) which acts as the rectifier when the gas transitions between insulated and suppression zones. I communicated with Moddel at the time who had already satisfied himself mathematically that the back pressure hehad to pump against did not increase in proportion to the energy extracted. His main concern at the time was funding and trying to find a low cost alternative, like self assembly using nano powders, to side step the large cost of milling an array of .1u holes through a stack of alternating layers of Casimir and insulating plates. I guess we should add "Lamb Pinch" as another possible path to heat. BTW, I liked your letter to the editor in latest IE. Regards Fran
