Wild west windvane
This gives you a feel for the Wild West. The windvane is a variant on the ones seen in countless western films. It is a wind-operated pump that brings water from the well when it’s windy.
It is a wind-powered water pump that functions in almost the same way as a common farmyard pump. The average windspeed at the location of the windvane is 4 m/s, according to the Swedish Meteorological and Hydrological Institute, SMHI. The optimal windspeed for our windvane is 10-15 m/s. When the windspeed exceeds 15-20 m/s, the vane folds and the system is braked. The windvane is nearly silent.
