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.

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

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.

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
