Wind Machines

Wind machines are the devices that can use renewable wind energy and generate wind power. Wind machines capture the renewable wind energy and convert the energy present in it to mechanical or electrical energy called wind renewable power.

Wind machines have rotors or blades that capture the kinetic energy of the wind and these are turned by the force of the wind. The blades are connected to the shafts of a turbine which is rotated by renewable wind energy to generate electricity. This electricity can be used as an alternative power source called wind power.

Two types of wind machines are available on the basis of the direction of the rotating shaft. Horizontal axis wind machines have blades like that of an airplane propeller. These wind machines are very tall and have three long blades to capture more renewable wind energy and therefore generate more wind renewable power. The other type of wind machines called the vertical axis wind machines are not much in use and not very popular. They have blades that go from top to bottom and these account for a very small amount of wind power generated.

A Wind Amplifier Rotor Platform can also be used to generate wind renewable power. In such systems modules are stacked on one another where each module has a pair of high capacity turbines and a wind amplifier. The wind amplifier increases the speed of the renewable wind energy that is directed towards the turbines to rotate them and the turbines then generate electricity.
