|The Rance tidal power station has recouped its development and building costs and is cheaper to run than nuclear. But how many other suitable sites are there?|
The Bay of Fundy is the obvious location. 53 foot tidal amplitude at the top of the bay. Largest in the world.
And if you constructed an enormous object with a total density of slightly less than water, you could extract E=mgh from that, but then your problem is you only get two high tides a day.
