Fabric windmill turbine blades could lower cost and weight
From
Technology Review – GE hopes to make wind turbines far cheaper, and open up new ways to design them, by ditching the stiff fiberglass blades it uses now in favor of turbine blades made out of fabric. GE says the project, which recently received nearly $4 million from the U.S. Advanced Research Projects Agency for Energy, could lower wind turbine blade costs by 40 percent.
This illustration shows what a cross section of GE’s fabric blades might look like. The fabric will be stretched over a composite frame (light gray) and central spar (yellow and green).
