The wrong kind of tide.

No; wrong kind of management.

In the 1970's Rolls having given Stanley Hooker the elbow found itself bankrupt after all it's high bypass engines failed the frozen chicken test for carbon bladed turbines.

When the government bought out the blighters and reinstalled god's gift to the jet-set, he redesigned them in titanium and found them much better mincers.

Several frozen freezerfests later the Rolls Royce jet engine is worth millions.

The reason the river barrages are not viable is that they have to be closed to shipping. There is no accord in the world that will save the environnment from rich people and money. It wasn't even mentioned past a few editions of the News Chronical when the people who made the Conwy Tunnel decided to create a marina from the tidal flats that used to house most of the waterbirds in North Wales.

However if they dig a tunnel to direct a tidal range into a reservoir separate from the rivers then they can use any amount of wilderness that the government are willing to steal from the locals for their not using it properly.
