Encore’s proof-of-concept SideWinder wind-turbine demo unit develops tremendous torque at its central shaft even in low speed winds. The SideWinder is radically-different than any other wind turbine technology being offered today and targets the most lucrative and currently untapped market for wind power: the low wind-speed ROOFTOP WIND market -- harnessing clean wind energy on top of mini-malls and buildings around the world. As of yet, we don’t have every aspect of the system optimized (we still need to engineer a soft-landing pneumatic or hydraulic shock-absorber system for the wind-shutters/louvers when they open). The shutters/louvers are made out of high-strength low-weight carbon composites and right now, because of the varying wind speeds and wind gusts that will change the RPM of the power take-off shaft -- we plan to connect the SideWinder’s central rotating mast with gears to a DC generator whose DC output is then sent through a high-power DC-AC inverter to give the end-user the AC power it needs.
