Recording the sound of a Windspire Energy Model 800080 vertical axis wind turbine, built in 2010, with a pair of contact microphones in Northfield, Ohio on January 5, 2022. The manufacturer states on the bottom of the unit that there are “no user serviceable parts inside,” which in this case is clearly too bad, as this unit is incredibly squeaky, like fingers raking across a chalkboard, and a bit wobbly as well.
