Reservoirs could give us cheap power

Norland View,
Sowerby Bridge
I AM not sure Matthew Ambler ("In power game nothing is free", Your say, April 29) followed the concept of my idea of using Baitings and similar dams for producing electric power ("Use dam water to generate power", April 21).
Water released from the base of the dam through pipes into the turbines could then go via a pipe-line back into the reservoir.
There would be nowhere for the water to go but up. The pressure and the weight from the volume of water above would push it straight back round; it shouldn't even need to be pumped back up. The dam could still function normally.
Using the Calder or any other river for hydro power would not be a good idea in my view. This would slow the flow of the river when swollen creating more flooding in the valley.

I hope this is a joke.

If it isn't back to school to learn some basic physics for you old boy. Your suggestion violates law of conservation of energy.

Doesn't this statement answer his question?

dear, oh dear, oh dear...........

i take it that alan never attended physic lessons whilst at school then, otherwise he would know all about how water pressures work. unfortunately, he is incorrect about what he thinks. for his sake, let me explain..........

if there was a pipe from the bottom of the dam to the top, even with being a lot more water in the dam than the pipe, the pressures concerned are in fact equal, and the water in the pipe would only reach at maximum to the exact same level as the water in the dam (and not 1 cm more). perhaps Adam should but an electric kettle that has the plastic tube water level indicator on it, and this will - quite clearly - show the error of his ideas...........

oh! Dear, oh! Dear,
They say what goes up must come down but it doesn't follow that what goes down the pipe will come back up again [at least not quite far enough to go around again]
'Laura Gravity' is on your side when its going down and against when its coming back up, I think, [not sure about law of conservation of energy]
