Wind Powering America engineering, into the curriculum. Supported by local businesses and utilities, small wind turbines at rural schools also introduce the concept of energy and the need for national strategic thinking on energy issues to the communities that participate in the program. To help states and Native American communities understand their wind resources, WPA created an anemometer loan program. Participants borrow anemometers and installation equipment to measure wind resources. Anemometer data can be used to help businesses, developers, farmers, ranchers, and homeowners determine wind potential in selected areas. Each anemometer collects wind speed data in 10-minute intervals. The data aid wind farm
Anemometer cups and arms, and may have a value between two and a little over three. Every previous experiment involving an anemometer had to be repeated after the error was discovered. The three-cup anemometer developed by the Canadian John Patterson in 1926 and subsequent cup improvements by Brevoort & Joiner of the United States in 1935 led to a cupwheel design with a nearly linear response and had an error of less than 3% up to . Patterson found that each cup produced maximum torque when it was at 45° to the wind flow. The three-cup anemometer also had a more
