Tim Streater brought next idea :
Which you get from where? And when it comes to pumping it out, where
does the water go?

It would be pumped out to a lagoon, then allowed to flow back via the
generators.
A lagoon eh? And just how big would this lagoon be and where do you
suggest it is located?

and waht do you fill it with? Yes, water - but from where?
