It’s actually not quite as crazy as it sounds. OK, it is crazy, but hear me out. Some inventor (Wolf Hilbertz) tried to build an island in the middle of the the Mediterranean Sea through electrical mineral deposition on a metal frame. There’s a fascinating video essay on its attempted construction and failure on YouTube.

You could also destroy mountains and use the rubble to expand the coast.

It’s really fucking stupid, but it would technically work.

Technically you could dig a huge hole, that would work too lol
Wouldn’t there be a lot of displaced water that needs to go somewhere?
