Jacques Cousteau and his diving saucer
In this June 1963 photo, Jacques Cousteau is seen near his diving saucer in the Red Sea.
In the 1960s, Cousteau led a couple of experiments in undersea living known as Conshelf One, Two, and Three (short for Continental Shelf Station). In 1962, oceanauts Albert Falco and Claude Wesly lived underwater off Marseilles, France, for a week.
The following year, about a half dozen oceanauts lived and worked in an undersea colony in the Red Sea for 30 days, while a support team worked above the surface. The Oscar-winning film "World Without Sun" chronicled their time underwater during Conshelf Two.
Conshelf Three, in 1965, aimed for a more self-sufficient habitat. Oceanauts spent three weeks going deeper -- more than 100 meters down -- and working on a mock oil rig under the surface of the Mediterranean near Nice. Cousteau, however, soon after repudiated the idea of exploiting the ocean's resources.
