It's certainly an interesting idea and plan.

I do find it interesting that the cost per MWh (~£90) for follow-up sites is pretty much bang on the same as people went mad about when it was agreed for new nuclear. Mind you, the intended lifetime is considerably longer than any conventional power station I can think of.

Its going to make a mess of Swansea bay by the look of it.

More reliable than wind at any rate.

How will we be able to tell?

It's awesome on many levels. And as for Swansea bay.. well, I lived there for three years. One time, I went in the waves wearing a pair of part-leather trainers and even though I dried & cleaned them properly afterwards the leather turned green and basically crumbled within a couple of weeks. I stayed out of the water after that.. While I was there Uni of Wales moved the marine biology department away from Swansea up further North because when the students went diving they couldn't see a damn thing.

I dunno if it's cleaner now (I assume it is, stricter regulations and all that ) and the Gower has some amazing surfing but the bay? Not really. Lovely beach opposite the Uni but not somewhere for swimming.
