There’s no way to synchronize traditional turbines, because they respond to the wind only. Below the roof, a short pipe leads to a fully enclosed turbine. Air rushes through a narrow channel between the two blades, creating a wind tunnel effect. To do this, they made pairs of blades that resemble airplane wings and stood them together in such a way that wind flows around and amplifies both airfoils.
So engineers at Sandia decided to change the paradigm for wind power in order to build something that is compatible with rooftops. How many turbines can do “jumping jacks” on this roof without hitting each other? Even if the turbines were safely spaced, their huge motions cause noise and vibration and require tons of maintenance. You'd run into the same problem trying to put wind-power turbines on a roof. Have you ever been part of or observed a gym class group doing jumping jacks? People start too close together and immediately spread way out so their arms can all clear each other. Instead, they’re using airfoil principles to essentially cover roofs in static chunks of airplane wings.
DIY HOME WIND TURBINE INSTALL
Researchers at Sandia National Laboratories have put aside infeasible almost-plans to install tiny wind turbines on homes, because they say the logistics just don’t work. Wind rushes between the airfoils and powers a smaller, more concentrated turbine below the surface.Ī new airplane-inspired solar technology could put wind power up on your roof.
