bring the link to the website so we can see what it can doJohn and Cecil wrote: ↑Apr 02 2021 12:29pmHmm. I think I just figured out why you asked this question. I searched online and I found a prototype of a small turbine that produces electricity from pressurized tap water. I wonder how many gallons of pressurized tap water it takes to produce 1 kwh of electricity? They do not have an answer for that question on their website. Perhaps it can be tweaked so that it makes even more power by reducing the water pressure even more, and a large tank can be slowly filled all night up on a hill above the house and then the house can use that water the next day by means of a gravity feed.
i dont know how your country does its water supply systems but here the city pressure is anywhere from 80psi to 100 psi
the house water main supply from the city is 3/4"
as soon as the pipe enters the house theres a shut-off valve and then a pressure reducing valve to bring the pressure down to around 60 psi.
if you tapped into the house water main in between the pressure reducing valve and main shut off valve with a tee to power a micro hydro. you could turn it off and on with a ball valve whenever you want electricity
find out city water pressure, see the size of pipe feeding your house and do some math
house main will do 1000 watts easy
