Pretty neat idea.

This reminds me of sun free photovoltaics. Somehow people managed to transform heat into coherent IR waves that could be converted by the usual PV cells.

Yes this. For a reason I remember an article "sun free photovoltaics" hence my comment. But I can't find it again on this page.. odd. https://en.wikipedia.org/wiki/Sun-free_photovoltaics
