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 get
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 needing
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.

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
Clever and interesting... But this device is not an acoustic analog of an
optical prism. It's much closer to an acoustic diffraction device.

It strikes me that this is essentially the mechanism that Neal Graneau
proposed to be responsible for the arc-liberated emission of energy in
papers such as
