When wind strikes a flat building wall, it accelerates as it rushes up and over the obstacle. Catching these wind gusts through a small opening, the wind turbine then funnels the force towards an internal propeller at the bottom of the unit. Called Aeromine, the boxy turbines generate 50% more energy than a solar panel and 16-times more when the wind is right.
They are designed for small-scale, commercial use, as they’re noise-free and incapable of killing birds. Because they sit on the edge of roofs, they pair well with solar panels. If a building also has batteries to store the energy, it could be near to total self-sufficiency.
