Angular Momentum, Parametric Oscillator and Over Unity

Jovan Marjanovic -- Angular Momentum, Parametric Oscillator and Over Unity

The goal of this work is to present mathematical and experimental proof of getting energy surplus or over-unity energy out of gravitational field by using pendulum as parametric oscillator.
In this work author definitely proved that the law of conservation of energy is not valid where the law of conservation of angular momentum was valid.

In this work the author will discuss:

- the law of conservation of angular momentum,
- principle of getting energy surplus out of pendulum which works as parametric oscillator,
- angular momentum and conflict with the law of conservation of total energy in orbits  of central forces (gravitational, electrostatic, etc.),
- angular momentum and corruption of centrifugal force,
- experimental proof of increasing potential and kinetic energy in the same time when the law of conservation of angular momentum is valid.

Key words: angular momentum, total energy, over-unity, parametric oscillator.

In the paper the thetherball like experiment was used as "proof". He writes:

"As expected, the weight really went up and velocity was increased first slow than faster and faster."

This is a very subjective conclusion. Nowhere do I see velocity data to back up this conclusion. A rotating object might appear slow or fast depending on its radius while still having the same linear speed.If the speed near the pole can be measured then conclusions can be formed.

You have scientific formula for velocity V = (R0 / R1) V0.

It is obvious that velocity will be increased when weight come close to the stick.
The experiment was just to prove that kinetic energy increase wasn’t happen on account of potential energy.

I have done an analysis on paper and to my surprise the forces cause the velocity to reduce. Your formula is when you blindly assume conservation of angular momentum holds which can only be proven by experimental data to end discussion. There are 2 cases:

Angular momentum is conserved thus kinetic energy is gained
Angular momentum is not conserved, due to "outside" influence, but energy is conserved

I think you can agree that forming a conclusion on an unmeasured quantity is not very scientific.

Here is a device for modulating the magnetic permeability of the core. For your second type of parametric resonance.  :)
There is no inductive coupling between the windings.

Hi broli,


The conservation of angular momentum is a proven FACT.  I am not sure why you believe kinetic energy is gained.  I am sure you have seen this law at work many times.  If you have ever watched a figure skater do a spin, they start a slow spin and then pull their arms in tight to their body while also bringing their legs as close together as they can.  When they do this their rotational speed increases greatly.  You can try this for yourself.  Find an office chair or stool that spins easily.  Sit in it with your arms and legs spread out as far as you can get them.  Have someone give you a spin.  Now pull your arms and legs in as close to the center of rotation as you can.  You WILL feel your speed of rotation increase quite a bit.  When you extend your arms and legs you will also feel your speed slow down just like the figure skater at the end of her spin when she suddenly throws her arms and one leg out to stop her spin.  If you chair is very easy to turn you can repeat that process a few times before the spinning gets too low to feel the effect.
