With all due respect bro this doesnt add up. it sounds like any temp drop is coming from your cooler water supply(with a closed loop itll warm up and stop working). maybe you could make a "swamp cooler" (therye great but only work where there is no humidity) and use the water supply to cool you miners first and then come up with a less efficient swamp cooler(becauae the supply is warmer) and that trade off could work in certain situations... just saying it doesnt make sense. if you figured out how to make cold from hot this is bigger than mining bitcoin youve broken physics and can produce unlimited energy im a rougue engineer myself man and i know that failed experiments are actually progress so godspeed but i feel like youre trying to accomplish something impossible
