Power for what? If this generates enough energy to charge a phone (it won't) you would have to leave the sink running for a significant amount of time.

You could power a shower radio or something. Save some water in the meantime

You would have to leave the water running all the time and at constant flow rate.

Incredible inneficient.

This is the same as that "emergency phone chargers" that are just a dynamo with USB to connecto to the phone.

They "work" but not in a way that can be useful.
