Hello to all for the past few years some of you know I have been building and selling small VAWT and learned from places like this Thank you all.
You have to really love this Green thing to keep at it witch I do.
I have learned the small VAWT .5Kwatt and up market is going to grow.

It is not just about the wings Push/Drag or lift design.
Not about the kind of PMA and can it make power with out stalling the turbine.
Most just charge batterys because it seam a lot easer to do.
But when you try to back feed the home with grid ties all hell break loose then and stuff just do,s not play well together.

I have learned about miss matching and the short coming of it and how it can doom a many turbines big or small.

I feel we have some thing that will help a lot of people with this miss matching problem.
Some will say what problem mine is working just fine.
I put together a VID on my products that helps show were some problem lay and how we over came them.

Good looking alternator Robert! 1kW @ 600 RPM out of that small an alternator is pretty decent. Looks like a Paykel & Fisher washing machine motor used as an alternator. Where do you get them?

Hello Rob I have a source here in the USA very low cost. I use the stock 60 Stator and build the Neo Magnet drum around it.
I have been asket to build a 2 ft VAWT for the home market here in the USA and abroud.
I will be using the stock F&P 60 drum and stator with the HD bearings and hub.

With a controller like the one in the VID it could be in the 200 to 300 watt range with some luck. one thing it will do is make useable power in the 10 MPH marker in dirty air at a supper low cost to cunsumers that are looking for some thing to off set there energy bill if the have wind.
