    DIY Wind-Powered Water Pump

    This is a pretty interesting project, but a poor instructable. There are not enough measurements, and the instructions are somewhat unclear. How long should the PVC be? What was the diameter of the metal washer? Which PVC did you use? Different PVCs will have the same outer diameter, but different inner diameter.I wanted to use this instructable for my engineering class, but it is difficult to recreate, causing me to purchase extra materials.
