West Somerset Lagoon would harness renewable energy for UK’s AI boom – and create ‘iconic’ arc around Bristol Channel

The architect of the London Eye wants to build a vast tidal power station in a 14-mile arc off the coast of Somerset that could help Britain meet surging electricity demand to power artificial intelligence – and create a new race track to let cyclists skim over the Bristol Channel.

Julia Barfield, who designed the Eye and the i360 observation tower in Brighton, is part of a team that has drawn up the £11bn proposal. It would curve from Minehead to Watchet and use 125 underwater turbines to harness the power of the second-highest tidal range in the world.
