Wind turbines in buildings – Is venturi the answer?
I’m a big fan of treehugger for digging out new technologies, social movements and a general bit of tree hugging. And then working out how some of the ideas could be integrated into the built environment.
How about this one – Sheerwind a new wind power start up from Minnesota have come up with a way of accelerating the background wind before it enters the turbine. The quadrupling of wind speed creates an 85% smaller turbine size for the same power generation.
The Invelox system funnels the air into venturi which then accelerates the wind into the turbine before it exits the funnel.
So the interesting bit is could this be applied to a building? Could the Invelox be on top of a high ride residential or office building, with the turbine at a low or mid point of the building with a reverse Invelox behind the turbine such that the air is sucked out by the wind pressures of the building itself?
Wind turbines on the top of buildings have been shown to not perform as intended, but could this be a better alternative? Could the Invelox generate more power in our already built up urban environments rather than putting wind turbines in our pristine natural habitats? Could the Invelox solve the problem of turbluence of wind which is bad for horizontal axis turbines?
One to keep an eye on I think.
