better connection

I've made a better connection between the windmill and the generator.
It works much better.

We had some >20 mph winds today and I had to stop the windmill due to vibrations.
I need to figure out some strategy for reducing the vibrations at high wind speed.
That is the fun of this project - there is always something new to improve upon or invent.

Conneced up the generator

I've connected a steel cable between the generator and the windmill.

I've modified the central post of the VAWT to make it less susceptible to vibrations. The center steel pole now has a 1 inch diameter rather than 3/4 inch diameter.
