Proteus is an underwater habitat with a greenhouse designed by Yves Behar

Swiss designer Yves Behar has unveiled his concept for an underwater pressurised research centre that will be "the ocean's equivalent to the International Space Station".
Named Proteus, the centre will have its own greenhouse to allow scientists to grow their own food 18 metres under the sea near Curaçao, an island in the Caribbean.
Up to 12 researchers and aquanauts – scientists who remain underwater breathing pressurised air for over 24 hours – will be able to live in Proteu
