So, I was thinking about what to do with waste heat, and somehow got the idea of a still that runs off the heat generated from bitcoin hashing.
No idea if it's anything that would work in practice, but in theory it should be possible to generate enough heat to get some amount of mash to 78°C... but I don't have the knowledge to figure out what density of GPUs, and what mechanism of heat exchange (if any) would make this work in a useful way.
So, I'm throwing this idea out to here in case anyone with more engineering skills wants to play with it.
But, in case someone decides to try it practice... save one of the GPUs for a miner of mine?
