A New Atlantis

Dogger Bank has a perimeter of 720 km and area of 17,600 km2, compared to Wales’ 20,600km2. It’s almost entirely within Britain’s territorial waters (sorry Germany). And it’s only 15-40 m below sea level to boot – so at depths humanity has constructed large engineering projects before.
Headline results: we estimate raising Dogger Bank would cost £97.5bn, but would bring present value benefits of £622 bn. Under the government’s standard method of cost-benefit analysis, this project would get a go-ahead, with a cost-benefit ratio of 6.2.
This would be way cool.
