re: Could the data center boom revive the rooftop solar industry?

I don't know how you get cooling towers into a closed loop system. I suppose you could drill a few thousand holes in the ground, run the heated water through thousands of piping loops in these holes packed with sand and gravel. Maybe the Earth and miles of piping can perform enough heat transfer to the earth to cool the water enough to go back into the building to collect more heat. I doubt it or the big factories would be doing it. The cost savings in cooling water makeup alone would not be insignificant

Do you know of any large factories that use a closed loop cooling system? Could it possibly be scalled up for the magnidata centers. centers.
