Energy ball home wind turbine

Like the "loopwing", the "energy ball" is a small scale wind turbine designed for home and commercial use. The design is manufactured by the swedish company "Home energy". The design uses the venturi principle to funnel wind within the turbine's blades, allowing the machine to operate with high efficiency and low noise. the turbine uses a set of six curved blades that spin around the center axis to create a sphere. Because the blades are able to funnel a large amount of wind into a smaller area, the "energy ball" remains efficient in low wind scenarios.
