Parametric Excitation

[Raui]

Just a little update, I have uploaded a paper by a man called Nicholas Minorsky to my google docs server. I encourage anyone interested to read it's a good summary of the 60 page report by Mandelstam.
Parametric Excitation

In the next few days I'm going to call up the local Aluminium specialists and get some sheets cut. I'm going to make a capacitive parametric machine. I'll post more on it when I collaborate my thoughts more Is anyone else in the process of making some sort of experimental setup?

Parametric Oscillator Experiment

IMHO there are interesting experiments in the link posted below. See the section on the self-tuning.

It's rather like creating a dam in etheric flow which normally is steady state flow.Opening and closing dam makes a waves in ether, that is radiant energy.

Thanks for starting this thread. It would be excellent if we can come up with a set of replicable experiments that provide anomalous results for us to think about. There is obviously something modern science does not know about electricity.

Given the difference between Transverse and Longitudinal waves, and my understanding of Tesla's Magnifying Transmitter, my intuition is that ordinary electrical devices operate using the principals of Light and Heat, and Tesla's Impulse Magnifying Transmitter operates using the principles of Pressure and Sound.

I have seen many independently invented "Free Energy" devices which look like the Magnifying Transmitter. The core parts are: Capacitor, Spark Gap, Resonantly Tuned Coils. The capacitor and spark gap together produce an Impulse discharge into one coil. The second coil is induced to oscillate, and if the impulses are timed such that the two waves are phase conjugate, the reverberations will reinforce each other and begin to amplify the voltage. This is just like an opera singer shattering a wine glass by finding the resonant frequency. The initial impulse is not strong enough, but when the reverberations are meeting in phase conjugation the power amplifies until the glass shatters.

It's crazy that people think the second law of thermodynamics applies to the entire universe. Any system which only used Entropy could never achieve dynamic equilibrium. It's obvious by looking at all of the "intelligent" or organizing processes everywhere around us in humans, plants and animals that syntropy is just as pervasive in the universe as entropy is.

I think it is important that we look at parametric excitation and harmonics together. Are they related and how ?

[boguslaw]

parametric resonance is a time machine, think about it

[SuperCaviTationIstic]

guaranteed they don't scale down if you keep the same symmetry as the large versions.

Bet you if you used asymmetrical capacitors, you could shape the dielectric field for added and focused intensity.

Everyone needs to stop thinking about symmetry and start thinking about complimentary ratios/geometry/function

STOP THINKING LINNEARLY
Experiment with curvature

[boguslaw]

I don't see the reason why they are not scalable down.Probably smaller device need just a regulation tool to limit power and prevent self-destruction.

Okay, since this is new ground i am wondering what would the resonant frequency of the circuit be if the capacitance changes over time.
I guess then the resonant frequency changes proportionally.

This is a result of the variation of capacitance (C in Farrads) with respect to time (T in seconds) which results in a negative conductance G (in Siemens). Hence the generation of electric energy.

Most are clueless about the importance of the Variation of Inductance and Capacitance with respect to time – and synchronous parameter variations.

So what about a variation of inductance?

A coil that mechanically alters the inductance could be realized to, maybe attached to the same motor altering the capacitance to ensure synchronicity and see what happens.

A bit discouraging is the statement by Eric :

Such devices tend to operate above 500 kva and are not scalable into smaller devices, and therefore are only appropriate for substations.

But if someone doesn´t try, then it will never be verified or proven possible.

[Raui]

This is exactly why we need to experiment. In my spare time (which isn't all that much at the moment ) I plan to make a spinning variable capacitor setup. Heres abit of maths about the possible capacitance changes in a device like this.

Say we have a capacitance, C, which is the capacitance of two semi-circle plates separated by 10mm of air with an area of 100mm^2. Now in the middle of these plates we have a rotating semi circle with the same area. Capacitance is proportional to area / distance. So with the second plate we have doubled the area and halved the distance, that is 2A/0.5D which works out to be 4 * A/D or 4C. Now say we have 19 rotating plates and 20 stationary. We now have 19C when the rotating plates aren't in the plane of the plates and then 76C when they are. A change of 19C -> 76C is quite a change especially if it's quick. You get the most energy out of the system when the change is at half the resonant frequency of the circuit.

Just a bit of food for thought.

-An effective way of capacitance changing can be by alternating between series and parallel configuration of a bank of capacitors.

That is true, but that is a pretty abrupt change and looking at the total capacitance of the circuit it is a variation, but not if you look at the individual capacitor. I wonder if it is more effective to vary the capacitance of an individual capacitor and if that should happen more in differentials of a sinusoid waveform.
The mechanical displacement of capacitor plates comes to mind.

[Raui]

-Here is where we will post our conclusions or interesting results from experiments-
-Inductance can change even when influencing magnetic fields are at 90 degrees to each other.
-An effective way of capacitance changing can be by alternating between series and parallel configuration of a bank of capacitors.

PS: I don't mean to spam I just want to keep the topic organised.

Coloured in red are writings that have been directly referenced by Eric Dollard at some point or another. I'll update as new documents, patents or papers surface. Some documents aren't hyperlinked because I can't find them or they're copyrighted. They are still worth getting a hold of.

[Raui]

I thought I'd take the current discussion from http://www.energeticforum.com/renewa...p-dollard.html and make it's own topic as it was creeping off topic. To sumarize for those who haven't read the thread, Eric Dollard came to the forum and posted two posts which are located here http://www.energeticforum.com/renewa...html#post90090 and here http://www.energeticforum.com/renewa...html#post90344

He pointed a group of us to research parametric excitation of an electrical circuit along with giving us more references to dig our teeth into. From my reading I have found;

A changing dielectric flux = displacement current or dielectric induction
A changing magnetic flux = magnetic induction

A change of capacitance (lower -> higher) = positive conductance
A change of capacitance (higher -> lower) = negative conductance

A change of inductance (lower -> higher) = positive resistance
A change of inductance (higher -> lower) = negative resistance

So the aim of our game is to change the parameters of our circuit as quickly as we can to create/cohere energy and if this energy gain is higher than the resistive losses plus the energy required to change the parameter we have excess energy we can use to power a load!

Time for experimentation, so who wants to play?
