If, Instead of digging a channel tunnel, we had put a dam across with a motorway and railway on top, the tidal surge would provide enough electricity for the whole of Europe, without CO2 emissions ( if's not one of mine, it's an article that I read abour 30 years ago by a Frenchman whose name I've forgotten).


The thing that always worries me about tidal power is the environmental impact, it could be absolutely huge, and it'll affect ecosystems that we know bugger all about.
