A moveable VAWT test rig incorporating 8 elements made from old drums, plywood , electrical conduit , a tirfor , etc .I made it on this old trailer chassis so it could be dragged around to the garage when lowered for construction and modification . the stabiliser bars can be removed when in transit. It could of course just be mounted in a solid concrete base without the need for guy wires.The top element has a shading vane to increase its effeciency & with a bit of modification this could be extended to all the elements .
