Double Pendulum Power

[TechStuf]

The physics simulation "Phun" or "Algodoo" even comes with a couple of Chaotic Pendulums as example scenes. If you think that the chaotic pendulum cannot be modeled mathematically... how does Phun do it, by smoke and mirrors?

Umm...actually......yes.  (It's ok.  The little things are easy to miss.)

Smoke and mirrors are a part of the process.  I assumed you knew?

But then, you know what they say about assumption....

Or maybe not.

P.S.  Math is rather like the Heavens.  Only the fool thinks he knows any one part of it completely.  But one of many cases in point:

@nybtorque

it works. see this french guy nicbordeaux. His channel:

I had a few mail-exchanges in the last year. This time he does not react for some reason..I do not know

What you and most other seems to miss is that the pendulums actually performs real work constantly; accelerating/decelerating mass; i.e. E(work)= m * a  * s. This is the work/power I calculate in the report, and propose might be partially productive (by replacing the mass by a resistive load or pumping water). And this does not violate the energy equilibrium.

I disagree. The system is given a certain amount of energy to start. After that this energy oscillates between kinetic and potential. With no friction it would continue forever. As such it acts as an energy STORE, but it is not GENERATING an excess of energy. If you bleed of the stored energy either by friction or using a generator, it will stop. The total amount of energy dissipated or generated will exactly equal the amount to energy given to it at the start.

Your proposal violates conservation of energy principles. Sorry, it just doesn't happen.

Your math is guilty of the same double counting error that Wayne Travis makes with his non working device, except your analysis is rather more complex.

Good find Kator.  There are numerous videos which point out the hilarity of hiding one's head in numbers.

The possibilities of resetting the device in that humble video demonstration alone, are numerous.

That is the funny thing about chaos.  It doesn't take much to cause many men's emotions to push their heads back under the comfy blanket of numbers. 

Another funny thing about chaos.  There are hidden within, many, many forms of order.  Order which man is neither capable nor worthy enough to experience, for long.

Chaos that's consistently repeatable, is no longer chaos.

And our "chaos" is, to those who've gone before (way before), is among the simpler forms of Order.

Of course, once all is said and done, there is lower order and then there's Higher Order.

Anybody curious? I was.
