I cant answer for Yonuh but the nice thing about a VAWT design is doing away the need for a slip ring, the little device that allows the windmill to rotate and not twist up the power cable. The basic speed control idea on most small wind turbines is to dead short the alternator and that has enough force to bring it to almost a complete stop. I have dabbled in this stuff too and currently use a 60watt solar pannel that I made myself to power all the lights in my garage.

Yes, that is one reason as well as the space constraint. I live in town so a 75 foot tall tower with a HAWT is a bit outside the building code in town. However, a VAWT up on my garage roof with a ten foot tower is fine.

I also plan to build a solar panel to supplement my VAWT. After all, even in the desert, the wind don't blow all the time though it does seem like it. Grin

And yes, a dummy load and I am also going to rig a switch that will short the alternator for my braking system.

It is made from two inch PVC pipe for the center shaft and spokes, the blades themselves are made from a section of 15 inch PVC that I found on the side of the road one day on my way home from work. The center PVC shaft has a steel pipe running through it on bearings.

Got the magnets I ordered in today and made sure the family knows that the box they are in should not come anywhere near anything that has a circuit board just to be safe.

There is 20 1 inch by 1/4 inch round magnets that each have a pulling strength of 24+ pounds.

Now I need the magnet wire, steel disks, and the resin to cast my stator in.

Think all the spools were about 10 lbs. Would fit in a $10 usps box.

Of course after I build the axial flux alternator, I will still need several other items the most expensive of which will be a battery bank consisting of several deep cycle batteries, bridge rectifiers, heat sinks, inverter, cables to hook the battery bank batts together, charge controller, terminal blocks, cut off switches, and enough cable and wiring to hook everything together properly. There are a few other things as well that I haven't put on this list but know I will need to acquire.

No I don't have a Delorean, wish I did though. Wink

I need to make five more coils and I do believe I have enough wire for that. I'll post a video of the coil winding process when I turn my last test coil.
