Where on the equator? (Score 1)

There seems to be a lot of concern about the lack of a decent place on land to locate the tower, which the article suggested would be O(50km) tall. Why not build it starting on the ocean floor? Heck, the ocean is only about 5km deep in most places in the Indian ocean. I also recall a bunch of Ayn-Randy devotees discussing designs for the construction of artificial islands- build one around where the tower exits the ocean and you have simultaneously avoided the problem of soverignty. jay-
