It is surely very nice work. The Atlantic Provinces have a soft spot for these verticals rotators, I see. Would be curious to know of what material the blades are made. Is that wood? The shape is quite carefully proportioned to within small tolerances. The theoretical Betz power limit for this size turbine in a 15 mph wind is just about 10 watts. See the IntegEner-W website (www.integener.com) for some views of a rotator that might be of interest and it explains the different blade shape.

It is clear that the "notch" has the purpose of assisting the unit to accelerate when moving slowly or stopped with a little bit of drag - a good idea. Maybe these can be produced in quantity for a market, they are so attractive.

The quote is interesting also. I would be happy to answer questions about making units that are a little larger in scale, despite being a little "dumber".

To Ed Lenz - if you have logged on to this thread, I ordered the small axial flux 3 phase generator kit on the WindStuffNow website just this morning with the PayPal button and think it might work fine with the projects underway here.

IntegEner,

Thanks for the reply and for pointing me in the direction of your site, there is a bunch of useful information there. Great job.

I will eventually be trying to market these as a small backpack/camping generator. I have been working on this design for quite some time, so hopefully it will pay off, although the fun in building is "almost" payment enough!

You are absolutly correct about the "notch" and how it works.

Thanks again for the comments!
