"A startup company based in Vancouver has developed a new kind of generator that could harvest much more energy from the wind. The design could not only lower the cost of wind turbines but increase their power output by 50 percent to as much as 100 percent, in some locations. Normally, when wind speeds drop, a turbine's engine becomes less efficient. The new engine, from ExRo Technologies, runs efficiently over a wider range of conditions. The design replaces a mechanical transmission with what amounts to an electronic one. Magnets attached to a rotating shaft create a current, but individual coils can be turned on and off electronically at different wind speeds." The company will begin field-testing a small, 5KW wind turbine by early next year.

Slashdot | New Generator Boosts Wind Turbine Efficiency 50%
Thank you Slashdot!!! News for Nerds!
This type of breakthrough is so crucial in these times of needed alternative energies. I hope these generators make their way into other facets of electrical usage, automobiles anyone?
