PM ? Buy or build it !

[iacob alex]

   Hi !
For people interested to play PM (perpetuum mobile/continuous motion ) principle (variable/oscillatory leverage ) , you can buy an "introductory" model , at :
    www.theswingingsticks.com
...or better , you can build your own construct , as :
    www.youtube.com/watch?v=BH8AKDhcSv4
To change the chaotically motion ( no regular  swinging and rotation ) , due to the input (electric battery...wind) , into a regular one (continuous swinging or uninterrupted rotation)...we can use an everlasting (gravity ) "battery" , changing a free joint (360*) into a "knee" joint one (180*).
A principle can be simpler than the sum of its parts...

Has anyone tried to draw energy off it?
