If radiative cooling technology, such as https://www.youtube.com/watch?v=caFzYvYAUo4 were coupled to thermoelectric materials or to a sterling engine then electricity could be generated. Harry On Tue, Jan 4, 2022 at 9:37 AM Jones Beene wrote: > The most interesting new - but actually old -

A diesel with double turbo loader is above 50% efficiency. You will never get there with a sterling motor in a reasonable temperature range. Key is to extract all kinetic energy in a gas explosion what cannot be done with a sterling motor. But you can run a sterling motor even with burning

The most interesting new - but actually old - engine development (esp. for those who think LENR has a future in transportation) is the re-emergence of the Stilrling design. This engine design and the Brayton cycle, in general, never made the grade for commercialization - before now, at least.

The changing dreamscape. We don't really know how steam engines would have evolved because they were out-competed by diesel engines. The steam engine really became obsolete because it was incapable of turning *particular* dreams into reality. Harry On Sun, Jan 2, 2022 at 9:08 PM William

I take it I'm the only Vort with first-hand experience with these old beasts. My grandfather was a brakeman on the Union Pacific railroad when I was a little boy. Back then, while all the passenger trains were diesel-electric, a lot of the freight haulers were still steam. Old Gramps would take

In this short clip Buster Keaton lights a cigarette by pressing it against the boiler of a steam locomotive. Would the surface of the boiler get hot enough to do that? https://www.youtube.com/watch?v=8AIyB_-HYcs Harry
