TMA's vertical axis wind turbine introduces competitive advantage
Design creates pull on the back side, contributing to 40%+ wind conversion efficiencies; doesn't kill birds; runs more quietly; and doesn't need to be installed as high, blending better with landscape. Generating costs estimated at 3.5 cents per kilowatt-hour, surpassing conventional energy sources.
It’s not much more than a nice press release, but the story says that the researchers estimate it’s cost per kW hour is about half of 2.5 – 3.5 cents. Or about half of what conventional energy production is at.
