My rotating model
Hi all,
Could you look at my model in
https://www.youtube.com/watch?v=GQUPaHE0vCg
with description below and give me feedback of how to improve so that it can spin longer? Thanks

No, energy conservation isn't violated, it NEVER is. Im not even going to give reasons, just google, im sure there are a ton of people explaining why
perpetual motion machines aren't possible.

The use of electric motors has long been seen as a good way to keep things spinning

Q) How to improve the run time ?
A) reduce losses !
in this case mainly
. friction with the air
. the 'wobbling' of the cylinders
in a similar vein:
I am fairly certain that most members here, myself included,
believe in conservation of energy, the laws of thermodynamics etc.
Yet many of us (myself included) hope for a new/unknown source of usable energy,
and keep investigating free energy claims in the irrational hope of a breakthrough,
WHY ?
P.S. it took years of my childhood to realise that a 12 Vdc motor used as a dynamo could not electrically power the 6 Vdc motor driving it

@Sulaiman
The 6v DC motor didn't like it cos the 12v dynamo was chucking out AC.
If you'd solved it back then, the world's power requirements would have been satisfied forever
Perpetual motion is always an illusion, as the energy needs to come from somewhere.
So, if you start with that premise, all you have to do is conceal a motor-driven set of magnets behind the backdrop and the jars will seem to go on
spinning forever.
Tricks like this can be used to relieve stupid people of surprisingly large amounts of money.

It is never going to spin indefinitely -- there will always be energy losses. But it is not a bad chaotic motion device -- similar in principle to a
chaotic pendulum. https://youtu.be/AwT0k09w-jw?t=52s

Those are those turbine topped lamp covers that rotate from the heat of the bulb under them. Are you planning to fake success in your next video by
putting a hot plate or some other heat source under them?
Or is that just a coincidence?
