I like the sound of this plan- creating tidal lagoons to generate electricity. Previous tidal power proposals included stringing a barrier all the way across the Severn, which was just too big and destructive a plan to be taken seriously (which is probably why it appealed to politicians desperate to pretend they were serious about renewable power).

There are six lagoons planned, including one in West Cumbria, but I don’t remember the coastline of my youth well enough to guess where they’d put it.
