Having read all of this and watched the video.
There is a person who posted on here in the U.K. "Stop4Stuff" who built a clockworks item too, except he used a pull-chain, it's in the older files around here somewhere.
My thoughts are that he's not really claiming over unity, even though the website has that in it.
The idea of using cows is not really a bad idea. Back home, we typically make the cows move throughout the field to thin out any unnecessary fat.
So getting the cows to move the gears would help them burn up some of the fat, allowing them to have leaner meat, which is tastier and healthier for us omnivores
In Fact I can think of more than one couch potato who should be on one of these devices
.
IF people would STOP using free energy label it would be more acceptable to those who know Thermodynamics .
