World's first hybrid wind/current generator could generate double the power

TreeHugger has a post on a combined wind power and ocean energy device that is due to be trialed in Japan soon - World's first hybrid wind/current generator could generate double the power.
Combining a three-bladed Darrieus turbine on top, a Savonius turbine underneath, and a generator in between, the SKWID power generation concept is claimed to be the world's first hybrid system "capable of maximizing the harvesting of ocean energy from wind and current".The SKWID, from the Japanese company Mitsui Ocean Development & Engineering Company (MODEC), is designed to capitalize on the energy potential available both in the winds above the ocean, and in the currents flowing beneath the waves. The device uses an omnidirectional Darrieus wind turbine sitting 47 meters above the sea on one end of a vertical shaft, with a different type of omnidirectional turbine design, a 15 meter diameter Savonius, spinning at the other end under the surface.
