The Energy Ball V100 is a spherical small wind turbine for small scale energy production, produced by Home Energy International. The annual yield is up to 15% of the energy demand of an average household.
The turbine is characterized by the 6 curved turbine blades which form a sphere.
The Energy Ball uses the venturi effect: due to the shape of the turbine blades the wind is accelerated creating a low pressure area within the sphere, thereby using a larger area of wind than wind turbines of comparable diameter.

“Innings and afternoons. Fly lost in sunset.
Throwing arm gone bad. There’s your old ball game.
Cool reek of the field. Reek of companions.”
