Proposed Bristol channel tidal barrier 7GW

For how many hours a day?


Some power close to 24/7, reaching maximum power for at least
half that time.

and it would provide a new motorway (and or railway)
between England and Wales along the top of it

Or alternatively to cause less of an environmental impact, and better access
for shipping, a row of tidal underwater turbine towers across the Bristol
channel, producing around half that power

another tidal barrier across the Mersey could produce 1.5GW
