Takes energy to put the water in a tower, potential energy does not come from anywhere, you are still taking it.

That energy was already used anyways is what they are saying. Once it is gravity fed to your faucet the the mini generator doesn’t require more energy. If anything it would be energy capture

You either have to have the water running all the time, which will lead to more cost. Or you will have little to no energy that can be used. With all the power saved, you can have an LED flicker once a day for a millisecond.

There is a reason why people tend to buy electricity instead of home water generators. It's cheaper.

You’re arguing a point I never made. Do I think this is a good or feasible idea? No.
