Great Possibility for Energy - Ocean Currents

If interested in new potential energy sources, check out the Scientific American article on a new turbine design that rides deep ocean currents like a kite rides air currents. If we were to put R&D funds into such technologies, imagine what we can do. For instance, I can imagine using something like this not only to power shoreline towns, but also other facilities such as desalination plants (which are presently expensive because of their energy costs). Like any new technology, once resources are put into research and development, more often than not I like our chances of figuring out how to raise efficiencies and lower costs.
