....or an easy way ,to find the exit, from a well known thinking "labyrinth"(I am reffering to the old perpetuum mobile problem),is to simplify,to start with a plain game,at:

You can see:a fulcrum,a bar and an acrobat,nothing more...
If we replace the acrobat with a self-moving "something",due to gravity and inertia...you have a real gravity powered device...

This is a good point for anybody to start with. It will teach more about balances than your typical PM device. There are several people including myself who works with this. It is very interesting and fun. ;D
.....topic is an allegory,a description of a possible PM/gravity power collector ,under the image of a circus "Wheel of Death".
As you can easy see,the wheel is in fact...a lever .
Here,I said : let's replace the acrobat with "something" equivalent,as simple as possible playing gravity "pressing" and inertia "storage".
From the long history of PM "folklore",we know the "classic" proposal:the hinged end of an arm...so anymore,"nothing to invent"?!
The feeling of wonder makes us to open "the eyes of knowledge'.
