Introducing the Energy Ball V100 and V200

This beautiful and low-noise turbine is characterized by the six curved rotor blades which are attached to the rotor hub at both ends. When the Energy Ball^® rotor turns it resembles an elongated sphere.  This unique feature causes the wind to move parallel to the rotor hub through the rotor. This wind flow direction (flow pattern) forms a key contrast with classic sphere shaped Darrieus turbines, whereby the wind hits the blades perpendicular to the rotor shaft or rotor hub.

Due to the unusual and exceptional aerodynamics characteristics of the Energy Ball^®, it creates a wind flow pattern that converges first and is then accelerated through the rotor, resembling the rapids in a river (the so-called Venturi effect). This translates into a higher aerodynamic efficiency compared to conventional wind turbine designs.  View videos of Energy Ball installations and exhibits.

The Energy Ball^® beginnings operating at very low wind speeds (2 m/s) and produces electricity at 3 m/s and therefore has a very low standstill time. The design makes the Energy Ball^®  transparent uniquely in the shape of a ball.  Select the link on the right panel to view the unit(s) specifications.  Please take note of the Energy Ball's light-weight design allowing for multiple residential  configurations.  The fact (as noted on the 'Sound Report' on the right panel) that the Energy Ball's noise level is not detectable above the background noise is a very favorable feature allowing for the placement in residential and commercial areas.  Power curves for the V100 and V200 are available on these links or on the right side of this page.  Reference the FAQs page for answers to frequent product questions.  Energy Ball product pricing is available.
