Boulder City, Nevada - Wind Sail Receptor Inc. has reported "a major breakthrough" in developing a rotor blade design that could change how wind turbines harness power, the US company said 2 March.
Using Bayer MaterialScience's polyurethane raw materials, the company claims its Quad Blade Construction has increased durability and weatherability, while reducing blade weight but maintaining costs. "Our tests show that our product provides three times more efficiency than existing turbines," said Wind Sail Receptor ceo Richard Steinke.
Steinke, formerly chairman of Amerytire, has over 20 years of experience in the Urethanes business.
He explained that most standard rotor blades on the market are constructed from glass-fibre or carbon-fibre reinforced plastics and are vulnerable to cracking or drooping after prolonged exposure to the elements. Boulder City Nevada-based Wind Sail Receptor claims its blades can "generate power in winds of five miles per hour and continue generating at up to 50 miles per hour, depending on the size of a new technology for a variable generator."
According to the American Wind Energy Association, in the United States, wind power installations were expected to be 7500 megawatts in 2008 alone - enough power to generate electricity for 2.2 million homes, the statement said.
Steinke estimates that he'll have a market-ready product this year that could be distributed through utility companies, possibly via joint ventures. He anticipates being able to sell the design across three platforms-from smaller units targeted for home and commercial use to larger half-megawatt and one-megawatt units.
Steinke uses Bayer MaterialScience's MDI (methylene diphenyl diisocyanate) aromatic isocyanate prepolymer and a mix of two different polyols in the rotor blade construction.
"I've always used Bayer MaterialScience raw materials in my formulations because they have the highest quality controls," Steinke said. "The blades are the most important part, and with the high quality of Bayer MaterialScience materials, they will surely stand the test of time," he added.
Since its inception in 2002 Wind Sail Receptor Inc. has been working to invent a wind energy system that replaces conventional wisdom about wind capturing energy technology. (RD)
