One way to use the wind!

Water-pumpers convert wind force into mechanical energy to make a water pump work. The rotating blades of the water-pumpers create a vertical movement of the pump in the water, thus activating the suction mechanism. Water can be pumped when the wind blows at 11km/h. In such a dry and windy region, no wonder that farmers of the Luberon wanted to take advantage of the Mistral and its average speed of 50km/h to irrigate their farmland!
