Double Pendulum Power

[nybtorque]

Hi all!

I've put together a report where I try to show how Euler Lagrange and classic Newtonian physics of a double pendulum can explain why certain mechanical and gravitational systems produce "excess" power.  The key is that we are dealing with an open system. The machine have to by firmly attached to the ground, or something heavy enough, to work and the other side of the Newtonian equilibrium is the minute movements of this heavy object.

By rotating a pendulum/unbalanced wheel we create vibrations originating from the centrifugal force.  By tuning the damping mechanism for example by an AC generator we can extract AC power directly from these mechanical vibrations. The interesting part is that it does not take any more power to keep this unbalanced wheel rotating except to initially set it in motion and to overcome friction. The vibrations however create power and the amount can be derived from Newtonian physics.

There are of course issues of construction and material strength.   

All feedback is greatly appreciated, please read the full report here:

@nybtorque:


That's an interesting concept you have developed. Have you built any proof-of-concept models in your research? Any photos you care to post here?

No, unfortunately not. I dont have the skills and resources to make a prototype myself. But an easy experiment to verify the effect is to put a bicycle upsidedown and safely fasten a heavy tool of sorts inside the wheel, which then becomes seriously unbalanced. Then pedal by hand, try to keep one point fixed and measure amplitude and weight at another point.

The interesting part is that you do not need to pedal any harder with the tool fastened inside the wheel than without. And you can certainly feel (and measure) the output difference. This is the power of vibrations. And it becomes greater with increased frequency of rotation by a power of three.

Hi nybtorque,

I have a problem to fully understand your setup shown in Figure 2 of your report file at scribd.com. I edited your Figure and uploaded below to refer to the parts.
I assume for simplicity the gear has a 1:1:1 ratio, okay? Now I also assume wheels B and C have to be able to rotate around their own shafts (see axle B and axle C) so that the pendulum weights could exert their force, okay?
Now my question is why arm D (which holds the wheels B and C) should rotate in accordance with wheel A?  I mean what force rotates arm D? because wheel A can rotate wheels B and C and maybe arm D will turn a little but why it should transfer useful torque towards the generator shaft?

To understand my question better, let us examine the setup from the generator side: suppose you switch off the prime mover (input motor) in your setup, everything is at standstill  and you grab arm D with your hand where the generator axle connects to arm D and you start to rotate arm D, okay?  I ask: will wheel A start rotating?   I am afraid wheels B and C will "circle" around wheel A as if they were planetary wheels and the rotation of wheel A remains casual, without transferring any significant torque. And this is what I think may happen when the input motor starts wheel A rotating.

What I am missing?  please comment.

One more thing: you wrote in the Figure: fixed axis on the right side of the generator. What does it mean? Is it a theoritical reference axis of the setup, maybe the axis of symmetry for the setup?

Thanks, Gyula
