wind power

From Scientific American: Daryoush Allaei thinks the wind power industry has it all wrong. Rather than turbines high in the sky, he says, it should bring wind to the ground, in concentrated form. “This is the right track. The industry has been on the wrong track.” Allaei’s Invelox “wind delivery system” is a big funnel that captures air at the top, and squeezes it through a turbine at the bottom. Wind entering at 10 MPH ends up as fast as 40 MPH, he says – meaning it’s no longer necessary to go to a hilltop for optimum conditions. According to SheerWind – the company Allaei heads – the funnel can produce 600% more power than a conventional wind device, and with lower installation and maintenance costs.
