There was once a Navy Scientist who wished to design and build a US Navy fleet of submarines out of glass. Of course these subs would not be made of your typical household glass. Perhaps a metal type glass, which could withstand the pressure or carbon nano-tube sheets, which I have thought of myself. 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 materials which where it may actually be possible, even likely that humans will attempt to build such things. Colonies under the sea, you see?

Perhaps we could design vortex flows to keep the pressure off the surfaces of the hull of the sub or undersea colony. Indeed, vortex creation would pull water away from the surface; movement maybe required at all times to use this principle for submarines. And you would need to put the underwater colony in relative fast moving underwater flows with vortex creation apparatuses up wind of the structure to get the water swirling. A simple fixed formation could accomplish this.

For submarines the blowing of air bubbles out as it moves might also be incorporated into the process to decrease hull pressure, which would also increase speed. Perhaps adding a wave energy wave creation feature when using materials such as carbon nano-tubes might be used since making the surface electrified would be easy. If we used such a concept also special coatings, which provide a gel formation around the boundary layer could be used as well. 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.
