If you thought domination of the world's software market was cool, get a load of Bill Gates' next technological vision: giant ocean-going tubs that fight hurricanes by draining warm water from the surface to the depths, through a long tube.
A second tube could simultaneously suck cool water from the depths to the surface.
Microsoft founder Gates and a dozen other scientists and engineers have a patent pending for deploying such vessels, which they say would collect water through waves breaking over the walls of the tub. Some variations have the water moving through turbines on their way down, which would in turn generate electricity to suck up the cooler water. The article is here.
