The purpose of sorting "hot bits" from "cold bits" is to create a temperature difference. I am assuming a temperature difference is already given, for example like the difference in temperature between the interior and exterior sides of a window pane in winter. Harry On Tue, Nov 3, 2020 at 10:55

So you want to build a demon. That proverbial creature that can sort hot and cold bits. New research has created a wonderful Graphene energy harvester you might be interested in. I guess you could attempt to use minor spatial perturbations an use that. but for any real energy, ya just can't

The propane fridge would be consistent with a prequel book entitled: Ice from Fire. In your example the propane supplies the fire or high temperature reservoir. An engine requires a temperature _difference_ between a reservoir and the ambient environment. Typically we think of an engine as

Make that “propane fridge” … Einstein’s first patent IIRC This challenge is inspired by the title of Gene Mallove`s book "Fire From Ice"….Has this already been done? Yes. At least in the sense of a propane fringe,

The challenge should be more symmetrical then I just described. Rather than boil water, the challenge should be to melt ice with a very cold reservoir where the ambient temperature is low enough such that the normal state of water is ice. Harry On Tue., Nov. 3, 2020, 4:04 p.m. H LV, wrote: >

This challenge is inspired by the title of Gene Mallove`s book "Fire From Ice". A major engineering goal in the past was to make ice from fire. That is given a very hot reservoir and ambient temperature, build a machine which will cause water to freeze. Can a complementary machine be built which
