The Power of Bubbles
Ever wonder why submarines travel so slow under water? No? Me neither. But there's nothing wrong with learning something new. Water pressure creates drag slowing almost any fast moving object underwater. In fact the faster a sub moves, the greater the drag.
So scientists searched high and low for something that could travel thru water will little to no friction and they found it; the bubble. Working with the Pentagon, they created a prototype sub that encases itself in a self-sustaining bubble. The bubble moves thru water quickly with no drag to the sub itself allowing it to attain greater speeds with greater fuel savings. The actual process of encasing an object in a bubble is called super-cavitation.
I wonder if this technology can be applied to divers.

Actually this was first invented by the Russians in the 1960s.

Never quote wikipedia as a source for anything. On another note, it's not about who invents something first. It's about who executes better. The Russians got to space first too, but we know how that turned out.
