Turbines are machines that convert energy from fluids, like air or water, into mechanical energy. They work by using the flow of these fluids to spin blades attached to a rotor. This spinning motion can then be used to generate electricity, power vehicles, or drive other machinery. Common types of turbines include wind turbines, which harness wind energy, and hydroelectric turbines, which use flowing water. In addition to generating power, turbines are also found in various applications, such as jet engines in airplanes and steam turbines in power plants. Their efficiency and ability to produce large amounts of energy make them essential in modern technology and energy production.
