Wind Machines

 · A 25-kW, horizontal-axis wind turbine with two blades and a diameter of 10 m has been operated for almost 3 years. This system is unusual in that both the spar and the blades are fiberglass. The unit unloads in high winds due to the flexibility of the spar ( 3 ).

Windmill

Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be a wind-driven wheel to power a machine. His description of a wind-powered organ is not a practical windmill, but was either an early wind-powered toy, or a design concept for a wind-powered machine that may or may not have been a working device, as there is ambiguity in the text and issues with the design.

Windmill vs. Wind Turbine

The windmill is a much shorter machine then that of a Wind Turbine. The Wind Mill uses more blades to catch more wind power thus causing more physical work to be produced. The blades are generally connected to an axle and then lead to the gears of a pump or that of a grinding wheel to help generate erigation for crop production.
