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?

We already have one and it's pretty big, it's called 'the sea'. ;-)

Cheers, T i m

Well some of our old coal mines are under the North Sea off the Durham
coast.
