spinning wind turbine blades.

Could purple
wind turbines decrease the carnage wreaked in the night by looming towers with
spinning blades on Halloween's iconic flying mammals?
It can also throw off the balance of a
wind turbine's
spinning blades, putting tremendous forces on shafts and machinery, leading to failures or shut - downs.
Under normal circumstances,
wind turbine blades are left to turn slowly in the
wind until they reach «cut - in speed,» the point at which they're
spinning fast enough to begin generating power.
The groups — the American Bird Conservancy and the Biodiversity Conservation Alliance — told the U.S. Fish and Wildlife Service in a 15 - page letter released Wednesday that between 46 and 64 golden eagles would likely be killed every year by the
spinning blades of 1,000
wind turbines planned by the Power Company of Wyoming.»
As the
wind blows, it flows over the airfoil - shaped
blades of
wind turbines, causing the
turbine blades to
spin.
The

wind turbine can
spin at speeds of up to 80 meters per second, or about 180 miles per hour.

spinning blades of huge
wind turbines have an effect on their surroundings, and it goes beyond aesthetics.

spinning the
turbines»
blades slow the
winds and diminish the hurricane, or would the hurricane destroy the
turbines?
It's actually pretty simple: The energy in
wind turns the
turbine's
blades around a rotor that is connected to the main shaft, which itself
spins a generator to create electricity.
The Vortex
wind generator represents a fairly radical break with conventional
wind turbine design, in that it has no
spinning blades (or any moving parts to wear out at all), and looks like nothing more than a giant straw that oscillates in the
wind.
Because the
wind turbines would require a modest amount of spacing between them to allow room for the
blades to
spin,
wind farms would occupy about 0.5 percent of all U.S. land, but this amount is more than 30 times less than that required for growing corn or grasses for ethanol.
Yvonne Wilke, Volkmar Stenzel and Manfred Peschka of the Fraunhofer Institute have developed a paint based on the textured skin of sharks that will help make the
blades of
wind turbines spin more effectively.
As the
wind speed increases, the efficiency decreases further as the
wind turbine feathers its
blades or even brakes them to prevent
spinning too fast.
