I just got my vawt up and moving. Thought some of you could advice me on the number of wing-sets I should put on top of eachother? Other comments? http://www.energy.ca.gov/2005publications/CEC-500-2005-084/C EC-500-2005-084.PDF

Looks impressive. The more the better, but it really depends on keeping the balance in check. The higher you go the more strain on that bottom bearing. But if you can mount a bearing at the top, then you can go much higher. Glenn The best time to plant a tree was twenty years ago, the second best time is right now. JAQ |

Glenn, I was hoping to put two supports from ground to lower bearing, thus avoiding a top bearing. The lower bearing is really strong, with double roller bearings. From a farm wagon, old, heavy. Also I should like a way to calc theoretic power from this, any suggestions? Thanks. cheers, J |
