The issue with harvesting the waste heat is the temperature of it (low.) I commented about this recently: https://news.ycombinator.com/item?id=45007358

Totally. I'm imagining something like heating for residential or greenhouses. Or a preheated input to some other heating process. One could presumably also spend energy to concentrate it a bit, but it's never going to turn turbines.

Still, the mind wonders -- here's a pocket of relatively warm, surely we could do something with that waste?
