Perhaps a metal type glass, which can withstand the carbon dioxide nano scientist who wished to design and build a US Navy fleet of submarines out of glass. I can remember some Sci-Fi writers discussing underwater villages of aliens under the sea with clear construction materials, fun stuff to think about indeed. Yet we are now entering a age of new matter which Colonies under the sea, you see?
Indeed, vortex creation would pull water away from the surface; movement may require at all the time to use this principle for submarines. And You could need to put put underwater colony in vortex creation apparatuses up wind of the structure to get the water swirling.
Perhaps adding a wave energy wave creation feature by using materials such as carbon nano-tubes might be used since I bet there are 20 ways to do this really? And so we need to invest more research monies in exploring the mastering of the seas. Think on this in 2006.
