Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

sexy!

energy ball

looks like aurora do a nice VAWT too
VAWT

2.25M high x 2.66 diameter = 6m capture area
perfectly reasonable for guys here, 2/1 belt drive cant help but think and F&P could do this.

Also think the PVC / Aluminium blades would be good for a similar VAWT as opposed to the Lenz type design.

Luck favours the well prepared

What do we make of it? Overrated turbines that bolt to your roof. Pretty much says it all. Nice engineering though.

I'm with you, John; is that the model they sell to deaf people? That roof has to be the sounding board from hell.

There's a video on You Tube somewhere showing this puppy spin (probably no load). I always wonder a little when there's a big "hidden" area at the base. My thoughts are it's hiding an electric motor that spins the thing for the camera.

I should talk; I'm currently building a VAWT, but mine will work or it'll become spare parts for the next project! My main shaft rides on upper and lower sealed ball bearings at least. It'll still make noise, but I intend mounting it atop a tower.

I've decided to build a proper AxFx three-phase alternator. It's twice the parts and my laziness isn't helping any in that arena, but I'm still pushing forward. It'll likely fly this weekend -- probably without the alternator, but that's in the works.!Edited by MacGyver 2010-01-16
