Resonnant circuits in cascade.

Elvis:

You could just as well use an oscillator to power everything. I used to own a fat book
of Tesla's patents and notes, written in his own words. His circuits were "all wrong"
by today's standards. He used paired capacitive coupling a lot, with shorting inductors.
Turns out that corrects power factor. Everything modern engineers do waste power.
For example, did you ever look closely at a simple voltage doubler/clamper? Once you
see and understand what they do, why would you ever use conventional rectifiers?
Everyone is so used to taking a loss, we've become biased against receiving a gain.
Look at things fresh from how they're commonly used.

Have you heard about Marconi and other scientist running to South America?  Some say that is where the UFOs come from - some of them anyways.
Any thoughts on that?

In series inductive/capacitive circuits... When a state of resonance is reached (capacitive and inductive reactances equal), the two impedances cancel each other out and the total impedance drops to zero.

the reactance drops to zero, not the impedance since Z=sqrt(R^2 + X^2). So even in this case if a ideal oscillator, you would be left with the ohmic resistance.

The total impedance of a series LC circuit approaches zero as the power supply frequency approaches resonance.

a parallel circuit is sort of a closed loop series circuit; so in the PC circulate high currents at resonance, while the SC can pass through high currents at resonance. (BTW: I suggest you to use SPICE for evaluating the behaviour of them. It is a quite handy tool for evaluating circuit designs.) But even if the reactance of the L/C combination would go close to zero - what it hardly does - you are still left with the ohmic resistance  that burns your energy and damps the circuit - in addition to the energy that is lost and is radiated off the circuit. Even if you use a negative *differential* resistance element (tunnel diode, gas discharge) to undamp the circuit, the oscillation will only be sustained as long as you provide the supply voltage to it. Shut down the supply, and the oscillation will stop. If the circuit would draw energy from somewhere else - as OU circuits are supposed to do so - the oscillation would continue.

So the only way would be to get into resonance with a external, naturally occuring oscillating phenomenon of sufficient energy, i.e. natural occuring radiation. The problem is just, there are no such natural radiation sources that lie in the rage of <1000Mhz, so that a simple L/C circuit could draw energy from then. Some promising energy sources to me seem to be the conversion of radiation in and above the THz range we have not yet the technology for, or the conversion of radioactive decay.

Apply this to using an antenna that can receive 7.4Hz.  {or maybe any broadcast frequency} and wouldn't this set up multiply the power??

no, but in the proximity of a broadcast station you actually could power some lightbulbs this way. This has been done in the early days of radio by some allotment holders, until the radio company figured it out and prohibited it by a lawsuit. This was the end of their 'free energy'.

I once too was very enthusiastic about FE, but the more I learned and experimented, the more the mist lifted and the things got demystified. Even the 'cold current' phenomenon can be explained by simple thermoelectric effects (see the 'peltier element'). I've seen a lot of OU/FE websites, also from those who claim to be scientists, most of them can not even handle a simple camera to make images which are not blurred. Even the power estimations for effects which are well known - but which are unfamiliar to them - were wrong by orders of magnitude. Not just that; we also came around some 'promising technologies' which are even patented  and sound quite futuristic (no OU/FE related). We got a science project about it too - in the end it all turned out to be at least unusable. Even the in the patents claimed basic effects were wrong from the root on. So I'm very sceptic about anything.

I suggest reading the publications of the "G?DE Institut f?r Gravitationsforschung", though we have no affiliation with them. They even set of a prize of one million ? for the one who can prove antigravitation http://www.gravitation.org/Start_/Experimente/experimente.html . They also have conducted some OU/FE experiments. Obviously noone wants the million; maybe one million is not enough 

I don't think we already invented everything or discovered any possible energy source, it's just that if the person in question who claims to have build a OU device shows the lack of knowledge of the basic principles of physics, I have a hard time to take him for serious. (I don't think of anyone special with this).

Here is a link to SPICE simulations of series LC circuit.

Thanks for the link. With SPICE one must keep in mind, that all is based on models, and they do not necessarily reflect the reality to 100%. The inductor models for instance mainly lack core saturation. The simulation also calculates probably with zero resistance wires. In reality you have always resistance in the wires and pins. You have loss in the magnet core and in the capacitor, thus they heat up. This all is wasting your energy, but certainly not included in the SPICE models. So SPICE is a good design tool, but the final judge remains the experiment.

(One should not underestimate the importance of wire resistance in high current applications. Even 'fat' wires can show a serious voltage drop if they are supposed to carry several amps)

You may look at LCLR-Network based induction heating designs, like this one: http://www.richieburnett.co.uk/indheat.html
There is a good explanation of what is going on in resonant circuits.
