Envertech has entered into a license agreement with Wind Sail Receptor (WSR) to use its patented wind turbine blade technology for manufacturing wind turbines up to 50 kW. When compared with the established wind turbines, the WSR blade design develops higher torques at lower rotational speeds. This feature improves durability and reliability as well as it provides quieter operation. The patented blade design also enables it to operate the turbine over a much wider range of wind speeds.
Richard Steinke, CEO of WSR, remarked that the company is delighted to have Envertech as a licensee to manufacture smaller wind turbine systems as the large wind turbine systems are developed by WSR in the megawatt range. The licensing agreement will enable WSR to provide its blade technology to a much wider customer base.
Envertech, a producer of advanced energy conversion technologies, combines the unique blade technology with a new permanent magnet generator technology to develop wind turbine products that are capable of generating more energy under ambient wind conditions. This will result in a rapid payback of the original capital investment and reduced costs for per kilowatt-hour.
The high quality of the Envertech system has been proved by the testing conducted for a 68-inch diameter turbine system. The Envertech system produced more power of 31 percent to 91 percent when compared with other systems at rated speeds of 28 to 30 mph. Increased wind power is continuously generated by the Envertech system that is not limited by wind speed. Other competitive systems on the other hand do not possess this ability to generate more power at greater wind speeds. The Envertech system is thus capable of generating 56 percent to 173 percent of more power at 43 mph (19.2 m/s).
Dr. Gary N. Benninger, CEO of Envertech, remarked that the company’s new generator technology perfectly suits the capability of the WSR blade to produce high levels of torque at low rotational speeds while retaining the stability over a wide range of wind speeds.
