IR is a very high entropy source of energy and useful energy can only be extracted from it as it flows into someplace cooler and you have a net increase in entropy. For example, one could use it to heat a boiler to generate steam to drive a turbine on its way to a cool condenser. Thought experiment: If their device could work one could transfer heat form one body to another even if both started out at the same temperature and both were in an insulated box. Just run the electric power extracted from the first through a heating element on the second. This can not happen in our universe. But it does not yet convert energy to electricity.

It technically would not be trying to transfer heat energy from a cooler object to a warmer one, i don't think. Still seems far-fetched, but amazing if true. :) I think the idea is that the antennas are still room temperature compared to the radiating heat, but instead of the heat transferring to the antennas entirely as heat energy to create equilibrium, it converts 80% of the energy to electrical?

If you can get diodes with such low forward voltage the thermal motion of the electrons would be sufficient to drive them through these magic one way valves. Maxwell's demons cannot function and never will. Perhaps if infrared black body radiation was low entropy coherent radiation like radio or microwave transmissions some form of this system might work. Otherwise, one cannot defy the 2nd law of thermodynamics. More thoughts: Why bother with the antennas?

More information is needed. Where is the increase in entropy? Do these things radiate even longer wavelength photons? It is implied that you could stick one in a beaker of water and the water would freeze while electric power is extracted. The universe does not work that way.

This report today asserts that the arrays can be made easily. The remaining issues are the collection of the arrays electrical output and converting the electricity to useful alternating current watts. What energy remains is yet to be seen, but any net efficiency over 50%, especially when the heat source has performed work would be a boon to energy consumers.
