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...
