Motion engineers are always on the lookout for new ways to capture natural sources of motion and convert then to electricity.  Wind turbines have been around for many years; some records show them being used by the Egyptians as early as 3000 BC.

Wind is made up of air, which is a gas. When air moves, it is called wind. Wind turbines work by placing propeller-like rotor blades on tall towers. As the air rushes by, its motion turns the blades. As they turn, the blade motion causes a rod called a shaft that is connected to an electric generator to turn. As electricity is generated, it goes into the electric grid and travels to wherever it is needed. This creation of electricity from moving air is an example of the transfer of energy from one source (moving air) to another (electricity).  READ MORE...
