Hi Jeff, This has been a good discussion with contributions coming from many corners. Thanks for the input and personal expertise.
What it all seems to boil down to is whether the Brady device can be shown to turn without any evidence of slowing down AND ALSO to power an external load like a generator - or does it eventually stop due to friction. The video is inconclusive on either points. The Brady device shown in the video was NOT connected to an external load like a generator. Regards, Steven Vincent Johnson www.OrionWorks.com
