Is anybody working on using all this waste heat for desalination?
I think cold seawater can be used for the external loop, through a heat exchanger where it would meet the heated pure water from the internal cooling loops. This would cause evaporation of the salt water which could be captured.

- imglorp 1mo agoI see, good point. One page over, there does appear to be a low temperature process which specifically calls out using waste heat. https://www.sciencedirect.com/science/article/abs/pii/S0011916499000454 https://www.sciencedirect.com/science/article/abs/pii/S00119...
