Ah, but does that include the equipment needed to synconize the turbine to the national grid? Otherwise you will not be able to sell the power, and only be able to use it locally. Besides which (in summer) there's not a lot of spare water - far too many boats using the locks (that doesn't matter for the water collection at Hurleston). I *just* got over the cill in the staircase 2 weeks ago - as it's a narrow staircase they have to keep reversing the boat "flow" every three boats, which uses more water.
