No, there is a govern that is connected to the pitch control of the blades. As the wind speed increases the blade pitch becomes courser. As the blades become more course there is less surface area presented to the wind so the blades slow down.
No it is powered by water. The flow of the water generates electricity. A wind turbine uses the wind to generate the electricity
yes
nothing wind turbines make the energy
No, wind energy refers to the kinetic energy generated by the movement of air, while a wind turbine is a device that converts this energy into usable electricity through the rotation of its blades. Wind energy is the source, and a wind turbine is the technology used to harness that energy.
Decreasing the blade length will increase the rotation speed, and thus the turbine speed ( for constant wind speed ).
A turbine blade slows down the speed of wind as it passes through, converting the kinetic energy of the wind into rotational energy to drive the turbine. The amount of speed reduction depends on the design and size of the turbine blade.
Wind power can not be made into direct weapon, however the electrical energy that wind power gives off can be used to power a weapon. An electric powered gun or military laser might powered by a wind turbine, just it might be powered by some other energy source; nuclear, solar, gas, oil, coal or hydroelectric
They both produce electricity
5mph
It depends on the manufacture and design of the wind turbine. Some small turbines can maximize power output with a wind speed of 10 mph. Larger turbines may be designed for higher wind speeds. Some won't even start spinning until the wind speed is over 10 mph.
A wind turbine is a form of electric generation. On top of a tall pole there is a turbine (fan thing) and the wind spins it around. The turbine is connected to a motor which generates an electromagnetic flow from the motion.
The wind turbine converts kinetic energy into wind, which then turns into wind and then mechanical energy. The energy is converted to an electrical generator through a shaft which turns it into electrical energy, or in other words, electricity.
