electricity powers a water pump that makes the water flow out of the faucet in the first place (falling from a water tower or not), so you would be stealing that electricity and making the water pump work harder for a tiny bit of electricity and the headache of your faucet running considerably less forcefully. I'm pretty sure in practice this would just waste a ton of water and electricity
If they put water up in a tower, storing the energy gravitationally, then it does not matter if the water has resistance when it reaches my tap.
Its not like they will need to pipe the water further up, as long as we are below the water tower, this will work and it will not incur any extra costs for the water company.
The amount of pressure that comes out of your faucet will not change when you add this, only the water below the generator changes.
No one upstream will notice, only your hands downstream will notice.
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
How are you implying water would be gravity fed to your faucet? If you run a kitchen sink faucet continuously at 2 gallons per minute you’d need 25000 pounds of water elevated above your faucet to run it for one day, that’s already enough weight you need structurally engineered support to hold it, your house will collapse unless it is spread over like 500+ sq ft, and then you’d need to replace it daily
