When most people think about erosion, they think about water, but wind can also be a significant erosive force. In most places wind acts in concert with water to produce erosion, but in many desert environments, wind is often the predominant erosive force sculpting rocks into amazing shapes. The erosion caused by wind is called “eolic erosion”.
Since ancient times human beings have recognized the power of wind, and they have learned to harness it constructing mills and water pumps driven by air currents. In present times we are using wind turbines to produce clean energy.
However, one of the least recognized uses of wind is in art. I have previously mentioned the use of vertical turbines in the sport of Wind Dancing. We are all also aware of wind chimes, but have you ever heard of whirligigs? See the video below.
These kinetic sculptures were made by artist Vollis Simpson. They are in the Vollis Simpson Whirligig Park in Wilson, North Carolina. The structures convert the kinetic energy supplied by the wind into mechanical energy used to produce movement in the sculptures.
