CWind Inc., a subsidiary of Owen Sound, Ontario-based New World Generation Inc., is developing a new design for wind turbines. The new design has no gearbox and involves using a friction drive power train to transmit the power from the wind turbine blades through a main shaft to a number of electrical generators.

The CWind friction drive is designed for managing torque excursions identified as causing damage to current wind turbine drivetrains. The damage is manifested as a failure in gearboxes. The CWind drive has an inherent slip feature that protects the power-generating components from torque overloading during a wind gust.

Field testing results of the friction drive (FD) 65 kW has confirmed that the friction drive is efficient and reliable in protecting the electrical power-generating components, according to the company. With a field-measured friction drive efficiency of 96.7% at relatively high slip rate of 3.5%, the CWind drives prove to be a viable solution to the failure prone gearbox.

Testing results for a single tire of the 2 MW indicate that the drive can be further optimized to achieve an even higher transmission efficiency of 98% at a 2% slip rate at normal operational conditions.

CWind turbines are three-bladed, horizontal axes, up-wind, variable speed units. In addition, they have distinct and exclusive characteristics. CWind’s technology features a friction flywheel driving multiple generators.

CWind is currently planning to move into the detailed design phase of its innovative FD 2 MW wind turbine and is actively seeking potential partners.

I am hoping that the price of oil actually rises in next few months. Why you ask would that crazy wind guy want the price of oil to rise when 99% of the world wants oil to drop???? Answer is that energy investments in renewables(wind) is dependent on oil pricing………..thus, OIL rising is good for Wind Energy investments!!!

And given the overall drop off a cliff of last 10 days in the stock market, anything UP will help my portfolio. APWR is the screaming buy of the century last 3 days. Thailand PR for 300 million DG Plant inside Thailand is going to PUMP the price in next 5 days!
