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?

  Nice to know that someone already did the math (the monster math!)

  That’s a really stupid way to do it, you connect the water turbine directly to the faucet. Why water all the tap water pressure.

    You didn’t read past the first paragraph.

    you can just hook the faucet up to your device, and let the water pressure drive the generator directly. In either case, for a bathtub faucet, this works out to almost 200 watts, or $25 per month

      Though what you could do is place small turbines in your piping so that any time you use your water for normal uses, it would generate some electricity at the cost of a loss of pressure once it passes through. Though it would be more efficient to just turn down the pumps generating that pressure to the new pressure setting and using the electricity saved there (if you are the one running the pump, water included in rent would transfer some energy to you but lose some overall).
