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.
Famous quotes containing the words energy and/or ball:
“After the planet becomes theirs, many millions of years will have to pass before a beetle particularly loved by God, at the end of its calculations will find written on a sheet of paper in letters of fire that energy is equal to the mass multiplied by the square of the velocity of light. The new kings of the world will live tranquilly for a long time, confining themselves to devouring each other and being parasites among each other on a cottage industry scale.”
—Primo Levi (1919–1987)
“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.”
—Robert Fitzgerald (1910–1985)
