Hello All:
I am in the process of designing my own VAWT and was just looking at the posts searched by VAWT in the "wind" cat.. I ended up designing my own gen, PM disk type 3 phase. It is going to be a bear to build, but I wanted something that could be direct drive and produce good power at even 1 RPS. I was looking at Ed's stuff, interesting but tailored for higher RPS's, not efficient enough, but good to re-engineer from.
I live in a low wind spot... Don't see much over 10 MPH most of the time, so I need to take advantage of the 5 to 8 MPH market. Basically, the helix will be 4' in "diameter" and 16' tall, on top of my new barn roof starting 20' off the ground, top of helix at 40' from ground zero. I am going to use three baffles at 120 degrees to intensify the wind a bit, but the main "edge" I hope will be in the gen design..
I am just starting so I am going to build a small 32" high model first to experiment with the baffles, a "thin" airfoil design.
