I’m no physicist, duh, but it sounds like thermal radiation is just waste radiation from heat when it is in excess of what can be used and these scientists have managed to figure out how to keep it from being wasted, resulting in a reduction or prevention of thermal radiation. It could be useful for maybe making cars more efficient, if it can be adapted.

It doesn’t sound like they broke any laws to me.

is the heat that is generated by a coal oil natural gas oven or aj nuclear reaction considered to be waste heat? If that heat could be turned directly into electricity —then it really is revolutionary.

The way I read it, the “waste” energy (e.g., infrared) is re-emitted at a different *angle* than the incoming energy (e.g., visible light). This means that whatever collects it needn’t block the incoming radiation. This could allow two-stage electricity generation using two different kinds of photocells (for the different wavelengths).

(I sort of remember reading about two-stage steam systems the used the low pressure steam that came out of the turbine to run the pumps or some such.)
