Why AI water use? It looks like Zambia's problem is mostly having water that isn't potable. If it's too dirty for heat exchangers, wouldn't they use closed-loop heat pumps, maybe some exotic working fluid? I even see a few mentions elsewhere of distillation using waste heat (but you probably get sludge to scrub out and dump).
