I am working on a new toy just because VAWT's are kool
? and they work well in trashy air.

so far I have a 10" PVC pipe 5'2" long. the pipe is class 200 pipe
? and is heavy, about 50 lbs.
I am planing on using one of my amatek 50 vdc motors with a gear ratio
of 1 to 5 or something in that neighborhood.

this is all i have done so far but i though i would see if anyone has
any good ideas on the blade configuration.

Wind Turbines are a lot funner to watch than solar panels

Hi Bryan

I toyed with a VAWT a few years ago. It is a lot of fun on the ground i did notice they seem to take more air movement to start. In my setup I had the blades on 3' arms the idea to give more leverage. I found the unit required more wind to start. If you keep the blades close together and offset as you have them resting in the pics you should get reasonable performance. The idea the the exhaust of the leward blade exits via the opposing blade and thus capturing as much energy as you can. For some other ideas on the VAWTs take a look at the web site www.solener.com it is the sit of a Spanish manufacturer with some interesting designs that are in use. Have you been able to do anything with the VAWT your grandfather built? That one just spikes my interest ever time I look at those pics.

Hey Mike
thanks for the link. looking at wind turbines never gets old to me.

I have not been able to get to La Junta to see what I can do to get the big VAWT up and going. I hope to soon before it get cold.

Hey Bryan

I found a site I will attach the link: http://www.windstuffnow.com/main/darrieus_type.htm

It has a 2 bladed Darrius with a vane on top to adjust the tac of the blades into the wind for startup. With modest modification a 3 bladed unit could be built up.

Hi Bryan

VAWT's are simple. And Big. Rrember they like the wind too.
Get it in the air like a Regular turbine. Not on the ground. out of the good winds...
