Windrotator™, a highly efficient wind energy generator, has been
developed to mimick the way sailboats adjust their sail to optimize
their speed in line with their angle on the wind.
Similarly, Windrotator™ adjusts the position of its tall vertical
rectangular airfoils to optimize the speed at which it rotates and
thus generates electricity.
Invented by Dr. Jacques Mettes, Windrotator™ can achieve efficiencies
as high as 28.3%. Capacity factors around 60% can be achieved by
stacking basic airfoils up to 50-100 m.
Since wind speed increases logarithmically with height, conventional
wind turbines aren't very suitable for use in backyards, where height
is typically restricted by council regulations.
Because of its low cost and high efficiency, Windrotator™ can generate
significant amounts of electricity even at low heights and at low wind
velocity, making it very suitable for use in backyards.
