It’s open access. The problem is in defining the system, with the further
difficulty that
you cannot apply equilibrium thermodynamics to the the planet and its spatial
environment.

I had an Intel student work this out in 2001, he actually won a price for it.
The basic idea is the same, if you transmit infrared radiation to the sky the
radiator cools and you can run a heat engine against ambient conditions.

The Second Law of Thermodynamics means you can't solely operate a heat
engine from a cold bath to a warm bath -- whether the cold bath is the
troposphere, or the ocean. But, as Michael Hayes mentioned, you *can*
run a heat engine between the troposphere (or surface) and space. But

Hi Folks,
In this overall category of tech,
Emissive Energy Harvesting is about 4-5 years old now:

The mid-infrared energy can be converted to energy that can be either used as
electrical energy or simply beamed off the planet without affecting the
It depends where in the IR you are talking about. There is solar flux incoming
in the near IR about 1-4 microns, nett outgoing beyond about 4 microns. The
outgoing is the planet’s dissipation, the entropic price paid for the
organisation resulting from the atmospheric and oceanic circulation, th
