Unless FF is over unity, it is using more energy than it produces, and is just a complicated resistance heater. Who needs it? If it is over unity, see above. The cost of installing and operating any added heat recovery gear must work out to be equal to or less than using power from another FF to generate the heat. No such technology exists, which is why FF is such an economic breakthrough.

I’d assumed overunity… else what’s the point? 🙂

You’re assuming that the onion works and is more efficient than any current thermoelectric options, right?

And Aeronaut’s meme, last I checked, was that an overunity FF has potential as an industrial heat source even without direct or thermoelectric conversion…

… as to what you two are going on about now I’m not exactly sure but it seems rather circular in outline 🙂
