Corkscrew wind turbine shows promise in Ohio
A corkscrew design affixed with wind turbines that a Cleveland State University professor patented is generating 4.5 times more energy from its perch atop Progressive Field than standalone turbines would, the Cleveland Plain Dealer reports.
The university has been collecting data on the design since it was mounted on the southeast corner of the ballpark on March 28, the newspaper reports. It is 40 feet tall and includes four turbines attached around the corkscrew.
CSU Professor Majid Rashidi found 11 mph wind can generate 1,288 watts of energy through his structure compared with 200 watts of energy if the turbines stood alone, the newspaper reports. The spiral design funnels more air to the small turbines.
