If, at minimum, every air conditioner in the world becomes 21% more efficient, then that's a bit of a dent in climate change.



I guess I was mostly thinking about the effect of reusing the IR beam. It gets a little confusing to me in that AC units move more energy than they expend. So for example a 10 EER means an AC unit moves 10x more energy than it takes to run. So if a 10 kW AC unit becomes 8 kW to run (~20% more efficient), a the same time the panel would beam out ~5% of 100 kW of moved energy? Or 5kw. If you reuse 5kW somewhere, then you lose ~70% of the potential climate change heat savings? 5/(5+2)?

I'd have to recheck al the assumptions here because I put high odds that I constructed this back of the envelope set of numbers with some mistake in it...


It also means that air conditioning may become accessible to some people for whom it wasn't before, e.g. because they rely on solar power, or because electricity is expensive.
