After reading the thread about the windmill in some foreign land I got to
wondering.
How would you build the cheapest and/or easiest to get up and running
windmill?
Let's try not to get bogged down in how efficient the system is. IOW, even
if we only get 1% of the energy from the wind out of the system let's say
that's enough.
I'm thinking more of how you would work the breaking, gearing, and the like.

Cheapest and easiest would be direct drive with no breakage.

Maybe I should also have put something about it being able to keep a battery
charged w/o damaging anything.

A savonius turbine made from corrugated plastic spinning a
permanent magnet axial flux generator. They have plans for
a 250W version.

If you want to build anything bigger, better, longer lasting
then the plans from this site are probably what you're looking
for.

Don't worry about breaking. Just leave it out in the wind. It will
break. What? You mean brake? Oh.... never mind.
