If you pumped water into the top of a water tower and vents were added to the top of the water tower to separate the tower reservoir from the pump to make two different but related systems. The tower would feed a tube of with internal turbines every few feet or less. the flow rate of the pump would have to be adjusted such that the rate of flow out of the turbine tube would be as close to as possible but slightly less than the the flow rate coming out of the pump so the tower would always be full and providing pressure to the turbine tube.
the reason that this would make energy is because the shier volume of water in the tower would provide potentially hundreds of times more the the pressure provided by the pump allowing the water to be pushed through potentially hundreds of turbines with the flow rate still being the same. this would create allot more power then is put in! Would this work? if not why not?
I also realize that at this point it wouldn't be much of a water tower but I thought it would make it easier to picture, my main question would be if you created one of these for purely generating power would it work?
