Double Pendulum Power

[nybtorque]

Vidar,
Thankyou for showing interest.  Well, at 3000 rpm it'll be a hell of a tickle for the kids...

I believe you are correct in some respects. At low RPMs the motor will rotate the "whole thing" since the centrifugal forces will not be big enough to overcome friction and bring the levers to oscillate. The same thing will happen if the pendulum mass are to low compared the the mass of the cogwheels, levers, etc.

To be clear; the output levers should not rotate but oscillate. According to my calculation an oscillating amplitude of about 40-50% of the pendulum radius is ideal (more or less as I've drawn the arrows in the pic).

If you short the generator the amplitude of oscillation will be really small generating little power. If there is no load, amplitude will be large, but of course; no power. So there is a maximum power somewhere in between depending on the design (masses, radius and frequency)

Physically there should be no delay (not exactly sure what you mean here); the forces are always what the are sort of... You say that the pendulum masses will not follow a circular path. This is correct. When the machine is oscillation I think they will move more or less horisontal depending on the amplitude, since upward acceleration is maximized when the position is at it's lowest point and vv.

So, there are some optimizing to be done with the different masses. Ideally the any mass that is not unbalanced  should be minimized and the pendulum mass should be maximized. That is what I mean by using lightweight cogwheels and levers. This enables the system to take more relative load from the generator. The double pendulum equations states that ideally m(load)+m(machine)=m(pendulum) is optimal.

But,that said. As soon as you get the system to oscillate from the centrifugal forces, you should be able to get "overunity". Allthough it is not overunity per se, since we are utilizing the "ground" as counterweight in the oscillations.

It will be really interesting to see a demo!

Hi again!


I've updated my report on a mechanical oscillator (double pendulum). In the previous version I made too many simplification and ignored the feedback momentum to the driving pendulum. I'm now using the Runge Kutta method to solve the equations numerically instead. By doing this it is possible to simulate all kind of setups. As an example I use the Milkovic Pendulum in the report. Please have a look. All possible feedback is appreciated!

Keep going....it is quite clear that more energy is produced in these systems than is necessary to keep them going.  An example:

Even the layman can see that, at least in the preceding example, much more energy is produced than is required to put the device back at the starting point/energy.

I think you are missing something. 

Sure energy is being transferred between the two pendulums and alternately causes one or the other to accelerate.  However I guarantee you the sum of all the potential and kinetic energies in the system remains constant. (or decreasing slowly due to friction).

As soon as you try to extract energy from one location the system will very quickly come to a stop as there is no excess being generated.

Nybtorque, they "guaranteed" the wright brothers never flew.  They "guaranteed" the atom would never be split....many of the "guarantees" of the high minded, are about as useful as a wet paper sack.

PHDs.....Piled Higher and Deeper.

And where is the pile sitting?

Squarely on top of the heads of those who blindly follow them.

That, I "guarantee".
