Waterpumping Windmill - Yggdrasil

Waterpumping windmill made of simple parts available almost anywhere. We used 200 L plastic barrel for rotor (savonius rotor), gear and brakes are made by old bicycle parts, and a diaphragm pump made of pvc pipe and old tire from a truck. The windmill is very mobile, and can be totatally dismounted in 2 hours for repairs etc. More specs available in video.
