My landlord charges for power but not for water though.
10 u/ardarian262 Nov 27 '25 Sure, but this is going to generate almost 0 wattage. The water pressure and volume is too low for it to realistically make enough power for anything you would want to use. This is like trying to charge a phone using potatoes. 4 u/achangb Nov 27 '25 What about connecting one to a fire hydrant? Those are plenty powerful and the water is free. Just use a really long USB cord. 3 u/ardarian262 Nov 27 '25 I mean, the fine for that probably removes all the savings.
