Duration: 40 sec

I couldn’t find video on how correctly functioning brakes work on large commercial windmills, but here is an example of a homebrew windmill furling in high wind.

A bit of video of otherpower.coms homemade 20′ diameter wind turbine on a breezy day. During this video you can just see it starting to furl – it’s generating between 2 – 3KW most of the time. This is the machine that powers our off-grid home and shop.
