A Savonius wind turbine will be constructed to determine how generators create
electrical currents. Electrical currents are made by moving electrons. Wind turbines aren’t as efficient as other horizontal axis turbines.

Introduction: A turbine is an engine whose central driving shaft is fitted around the vanes whirled around by the pressure or water or hot gases. Wind turbines come in two general types, those whose main turning shaft is horizontal and points into the wind, and those with a vertical shaft that points up. The Savonius is an example of the vertical axis type. It consists of two simple scoops that catch the wind and cause the shaft to turn.
Horizontal axis turbines are by far the most common kind of wind turbine. These turbines feature wing-like blades that generate aerodynamic lift as the wind blows past them, causing the central shaft to turn. To operate at peak efficiency, this type of turbine must always face directly into the wind. Many horizontal turbines have a large wind vane that acts like a sail, helping them to stay pointed in the right direction.
We are surrounded by hundreds of appliances that use electricity to do work. But what is electricity? Basically, electricity is a flow of electrons in a metal wire, or some other conductor. Electrons are tiny particles found inside atoms, one of the basic building blocks of all matter. We call the flow of electrons through any conductor a "current of electricity."
Each electron carries a tiny negative charge. When they move through a conductor, they produce an invisible field of magnetic force, similar to that found around a magnet. The strength of that...
