Title: "Perpetuum mobile" is "on air" !?...
Post by: iacob alex on September 29, 2019, 06:10:44 PM
.....starting with a mechano-electrical toy (battery "assisted"...), playing an erratical swinging motion , at :
https://www.theswingingsticks.com/how-the-swinging-sticks-works.php (https://www.theswingingsticks.com/how-the-swinging-sticks-works.php)
.....then with a mechanical toy , playing an erratical swinging also , at :
.....and a proposal to evolve the mechanical model into a gravity continuous unbalanced leverage ( continuous pulsatory rotation ) , at :

.....if we take into consideration : gravity free fall , rotational inertia and a single self-switching of the gravity unbalance ( torque differences the same side of the fulcrum ) on the top ( or bottom ) position...or an "inertia assisted" gravity free fall.
As a matter of fact we can perform a " minimum minimorum " design...

.....if you simplify the well known "swinging sticks game "(erratic swinging/pendular motion ).
So , you can :
-remove (take away,extract) the electric circuit (and battery...) as:
- https://youtu.be/RlAtXeDY7qs (https://youtu.be/RlAtXeDY7qs)
- https://youtu.be/PWg6TG2bkFU (https://youtu.be/PWg6TG2bkFU)
-place a magnet in every stick ( intended to repel one another...)
- add a "knee joint" (180* limiting rotation joint) for the small stick
Now , we have the possibility to play a "new game" ( regular rotating inverted pendulum motion ): "self" rotation due to a continuous gravity unbalance on the same side of the fulcrum and rotational inertia !?
Spare parts : fulcrum/support , two sticks ,two magnets , two joints...if you intend to build and test your own "toy".
Simply , we replace a battery assisted motion (swinging) with a moment of inertia asssisted motion ( rotation...or "self" rotation due to gravity fall and inertia ).
Inertia helps every turn ( or half turn...) to tumble the torque difference ( gravity unbalance ) on the same side of the fulcrum ...resulting a continuous pulsatory rotation.

.....maybe , not as a gravity "self "moving "" shape ", but as a big size. , at :
https://youtu.be/88Z2x1MEex8 (https://youtu.be/88Z2x1MEex8) ( a big wheel concept in France )
https://youtu.be/watch?v=qp5xqzGFcAQ (https://youtu.be/watch?v=qp5xqzGFcAQ) ( a big height leverage proposal )
.....if we take into consideration the real "source" ( gravity level potential ) , at :
https://theory.uwinnipeg.ca/mod_tech/node32.html
W   So , the main "factor" appears to be the velocity of the free "falling" unbalance , or the change of a high levei of PE into a greater KE.
.....but the "shape" remains to be tested !
