I'm another who fails to understand why we do not more widely use flowing water to generate electricity. Water, as rain, is taken up into the clouds without cost or man made energy. Everywhere it falls it contains the potential to liberate gravitational energy into something useful.
There are many small rivers in the south of England that have year round flows that could have a relatively simple flow turbine. Yes, they do need servicing, but that is not an insurmountable problem.

I have friends that have tried to arrange to generate energy from the flow of the river that passes through their farm. But it seems that although they own the land and the fishing rights they don't have a right to install a "mill", that rests with the local Bishop as the medieval laws that were used to control the building of mills to grind corn and other cereals still apply.

This is insane, but to change the law is probably unachievable: too many vested interests and an in built resistance to change.
