Free Energy | searching for free energy and discussing free energy

A third section to the presentation on Erfinders website has been posted.

This will show how to keep ressonant conditions through out a device, allowing propagating energy through the engineering of induction oscillating 90 degrees out of phase with conduction. This is what people mean when they say we should be enginnering around induction.

This concept is the father-mother of many free energy devices. 

@armagdn03,

Thankyou very, very much for your posting of this information,
This is precisely the information I happened to be looking for at the moment, Wireless transfer of energy through resonant LC coupling. Greatly appreciated!

Here is an excellent tool for preliminary calculations, if you are wanting to play around a bit.

If you start playing with series LC circuits the ressonant point will be the same, but the impedance function on this calc will not give an acurate awnser.

an R - L - C - f Nomogram as a PDF-File

This nomogram provides a quick graphical way to evaluate relations between R, L, C and f according to the corresponding formulas.

Its use should be obvious: Just look where the lines of the two given values (components or frequency) cross each other and follow the line of the value you're looking for.

I provided two nomograms: One is for the overview of several decades and with a second one with only one decade results of higher precision may be evaluated.

Should you often have to deal with the evaluation of passive components I recommend to hang these nomograms on the wall, just like I've done since my first steps in electronics. You will very soon get used to use them over and over and won't want to miss them. They are really convenient.

The power Tesla is referring to in almost all of those quotes on "http://www.forgotten-genius.com/" is referring to what I call Oscillation power (or Reactive power).  Here is an example of what he means:

You have a capacitor of 0.2 micro farads and a resistor of 20,000 ohms.  Lets assume we use a 10,000V source that can supply 1amps.  We have a spark gap so that when the capacitor reaches 10kV the spark gap discharges into a 4 micro henry inductor of very low resistance (i.e. large wires).  So, the capacitor and inductor make a tank circuit when the spark gap discharges.

The time it requires to charge the capacitor up to 10,000V is roughly 0.004 seconds.  Since the capacitor is discharged so rapidly when the gap fires, we can neglect the fall time of the capacitor.  This means that we can fire the gap at about 250 times in one second (250Hz).  How much energy is in the capacitor when it dumps into the inductor? 
E=0.5*C*V^2
So the there are 10 Joules in the capacitor when it fires.  We are inputting P=10/0.004, about 2500 Watts of power into the tank circuit.  HOWEVER! What is the power in the tank circuit - it is NOT 2500 Watts!  The resonant circuit oscillates at 177,940 Hz [ f = 1/(2*PI*sqrt(LC)) ].  The time constant of the tank circuit is 5.6 micro seconds!!!  The energy in the capacitor is still 10 Joules, so the power of the oscillation is 10/5.6micro which is equal to about 1.779 Mega Watts (1,779,406 Watts). 

Do we have over unity?  No we don't, that is because that 1.8 mega watts of power is all reactive.  This means that the 10 Joules of energy is only tossed back and forth between the capacitor and inductor 177,940 times in one second but the amount of energy in the system does not change (just 10 Watts and decreasing due to resistance).

How does this apply to anything useful?  Well, it allows us to take an oscillation and passively intensify it.  We can then use a resonant cavity (which is a device that increases the amplitude of a wave by bouncing smaller waves of the same frequency back and forth within it self many times, each small wave adds to the others before it dies giving you an over all wave of the same frequency but large amplitude) to amplify the oscillations and distribute them over greater distances. 

That's what a Tesla coil is suppose to do - not make sparks.  You transfer a slow vibration (DC or low frequency AC) to a very intense high frequency oscillation with a tank circuit.  The field of the primary inductor magnetically couples to the secondary (so the energy - 10 Joules using our last example - is input through the magnetic field).  The secondary acts as a resonant cavity for those waves (hence the quarter wavelength - just like a guitar or flute, all it does is amplify the vigorous oscillations of the tank circuit).  Whatever you connect to the ground terminal of the secondary, it will also begin to oscillate at whatever frequency the primary tank circuit is at.  Those vibrations can go for a very long distances assuming the ground plane will accept those frequencies.  The earth for example likes low frequencies, harmonics of 7.5Hz.  Telsa said not to use below 30kHz when using the earth.  You can definitely use higher than 30kHz but the oscillations will not traverse the planet, they will drop off as you get away from the transmitter. 

Those oscillations I'm talking about travel through the ground plane (whether its the earth or a wire), they do not travel in the air.  You can collect them using another Tesla coil whose secondary matches the same frequency as the oscillations. Basically you can transmit that 10 Joules of energy from one Tesla coil to the other using the ground connection - disconnect the ground and you stop transmission like cutting a wire.  However, if the two coils are close enough they can magnetically couple like transformers, which can go pretty far but not nearly the distance that the ground oscillations will cover. 

Unfortunately Tesla tried to tell people this, and no one understood it and they ignored him.  They still ignore it when he has patents and papers which tell you EXACTLY how to do it.  Read his Colorado spring notes - it even gives the capacitance, inductance, and voltages he used, shows pictures of lighting up bulbs in a field 100s of feet away (well past the magnetic field coupling range) and still no one uses this technique. 

Whats best is that they (Tesla coils) can pick up outside oscillation very well.  Mine is 15 feet tall and in the building its in it produces 15Volts at 60 Hertz and its resonance is 240kHz!  That would make it the 4000 Harmonic but 15 Volts for the 4000 Harmonic is amazing, just think if it was tuned to 60 Hertz haha!  I could draw all the power I wanted from the Grid!!!  But this opens the door to new ways of energy harvesting that a solar panel could never do. 

Once I can get a source that has enough UHMF, I plan to power a 25W light bulb from hopefully greater than 30 Meters, which should beat MIT's pathetic 3 foot display.  I think it can go farther than 30 meters but it really depends on the frequency and how much voltage my setup can withstand - distance for a ground oscillation at 250kHz is very dependent on the voltage and it should die off pretty quick because 250kHz is way too high for the earth - time will tell I suppose.

Hi armagdn03,

thank you for starting this very important Introduction to Resonance topic.

I have known for a while now that this is an area I need to better understand to further circuit effect quality. So you have my full interest and support to your topic.

I applaud your effort and am very grateful for you to take time to share your knowledge.

"Telsa said not to use below 30kHz when using the earth. "

Did you mean below or did you mean to say above.

When the Primary gets hit and transfers to the secondary, there is also the primary flyback that has to be considered and I am wondering if there is a way to calculate this in advance. What I mean is if the secondary winds up with 10 joules, the Primary would have spent the 10 joules less the flyback.

@armagdn03

"ah....now we walk into the world of transducers and how to sever ties to the source. "

I am right up to this point. lol

How to re-condense the explosion or expansion. Hmmm.

The only way I have figured so far is by using multiple capacitors that all charge up to a maximum voltage, then discharge the capacitors in multiple individual circuits. Then recombine those outputs. So one LC circuit could run 10 LC circuits that run 100 LC circuits then output.  The first LC would have its resonance, then the 10 LCs would be constructed for the resonance of the output of the first LC, then the 100 LCs would be constructed for the resonance of the output of the 10 LCs.

The thing is trying to do this through trial and error could take decades. Unless if there is a way to calculate the components, turns rations, etc., Hmmmm again.

But here is a concrete question.

Let's say a FG only had one frequency that was close to the resonance frequency required but not right on it. Is there a way to add a potentiometer to the LC circuit to then tune the circuit to the one frequency in order to achieve resonance.

You are making this to comlicated, its simpler than you think,

L and C dictate the resonant frequency, not R. A pot will vary resistance, and so will have no effect other than to make the waves decay more quickly.
An LC is a natural way to condense expansion, followed by expanding contraction, over and over. Think in cycles, the world is composed of them.

"Telsa said not to use below 30kHz when using the earth. "

Did you mean below or did you mean to say above.

Oops yea I meant that you shouldn't use waves above 30kHz for the earth - sorry. Again that is for a complete global transmission. 

For example, a person could create a motor that is based on an LC, the rotoverter is a good example, terribly constructed for its perpose, but thats because they are taking existing equipment built for one thing, and using it for another application. They are tuning the load, to the source. If you have a room full of tuning forks, you are multiplying your power through transfer from one system of resonance to another. Do you think that the adition 100 forks makes the origional die 100 times quicker? this doesnt match what you would intuitively think, or what you would find experimentally. The tuning forks can take on different forms, as long as they are tuned to one another.

Someone asked a while back on a thread here if turning on a huge ammountof radios would depleat the antenas power, great question, it applies.

One antenna will NEVER have the same amount of energy in it as what the radio transmitter is producing.  If you summed over all of them, and you had an infinite amount 360 degrees to catch all the RADIATED energy, then the sum of all of them would equal the energy the transmitter RADIATED out.  A tesla coil DOES NOT RADIATE the energy into space.  The energy from the transmitting tesla coil will be divided by number of receiving Tesla coils that are placed UNDER LOAD. 

In the case of your tuning forks, it depends on how you are driving them.  If you RADIATE the sound across the room, then it will be the exact same thing as the radio antenna.  The energy from the transducer is placed into the air and that energy spreads to every point, getting weaker due to its spread the farther distance you go.  100 million tuning forks placed around that transducer will collect a small amount of the energy emitted based on its distance from the transducer, but not one could ever have the same amount of energy that the transducer put out. 

HOWEVER, if you pass the sound waves through a table, they will not be radiated into the air.  They will reflect back and forth and stay within the boundaries of the table.  Now if you connect your 100 million tuning forks to the table, they will resonant each from the table oscillations - all with the same amplitude.  However, if you connect a load to each of those tuning forks, it will damp the table oscillations and the transducer will have to supply more energy to keep things going.  The resonant frequency of the table comes into play too since certain frequencies too high or too low might attenuate the sound waves traveling through it and make them not go as far - your hoping the table is relatively broad band if you want to use a wide range of frequencies.  This is how a Tesla coil is suppose to work.  If you have 1 receiver, that receiver can collect 100% of the energy that the transmitter sends out, regardless of distance.  You will not find that the case for a radio transmitter - since the energy is radiated away into space.

How you could power stuff with just the oscillations of each tuning fork without placing them under load I have no idea.  But you seem to allude to the possibility.  My ears are open, you can tell me any time.
