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 past it, but other factors influence the rotational speed, including turbulence produced by the apparatus, increasing drag in opposition to the torque that is produced by the cups and support arms, and friction of the mount point. When Robinson first designed his anemometer, he asserted that the cups moved one-third of the speed of the wind, unaffected by the cup size or arm length. This was apparently confirmed by some early independent experiments, but it was incorrect. Instead, the ratio of the speed of the wind and that of the cups, the "anemometer factor", depends on the dimensions of the
