Comment on My apartment building gives me free water but I pay for electricity. What if I run the faucet nonstop and rig up a hydro turbine in my bathtub to generate my power from it?

  You’re thinking too small: water cool your apartment

    The water can even directly drive the fan!

  Evaporative air coolers only need enough power to run the fan.

    Unless you live in a desert, or some other area where added humidity is a bonus then “swap coolers” are doing more harm than good.

      That’s true. Humidity is a negative here in the summer, would like more in the winter.

      How about pumping really cold water through radiators? Not as much cooling as AC, but with free cold water…
