World's first real Free Energy Flashlight - no shaking - no batteries! No Solar

[gravityblock]

Below is an image for a memristor test circuit.  This test circuit should work with the coherers and with testing the ELFE flashlight.  When S1 is closed the LED shows the status of the memristor. If the memristor is in the low resistance (on) state the led will light. If the memristor is in the high resistance state (off) the led will not light. S2 turns the memristor on. S3 turns the memristor off.

The 3 volt battery and 1k pot supply just enough voltage to light the led without effecting the on off state of the memristor.

Coherer won't charge any batteries. You need to power the coherer that it can detect any impulses at all. In other words it consumes energy, it does not harvest it.

No, sorry Mark, not really. The wire wound around a cylinder is a simple coil. Coils with such small diameter are called "small loop antenna" or "magnetic loop". Small loop antennas do not couple with the electric field, they couple to the magnetic field, and as such the Faraday-cage effect is irrelevant. However, small loop antennas have extremely poor efficiency, but the main problem is that "the_big_m_in_ok" does not understand that the gain is definitely not at all proportional to the length of the wire used. It is a function of the geometry, the Q factor, the impendance, the inductive reactance, and the parallel capacitance that needs to tune the antenna to the required frequency. So no, more layers will not give more power.

Not sure if you understood. The Faradays Cage effect would prevent any signal reaching lower layers.

Of course I understand. But as I told, a small loop antenna couples directly to the magnetic field, while it is largely unaffected by the electric field (that's why it is also very well suited for electrically noisy environment, because it does not catch the parasitic electric field). And the Faraday cage shields only against the electric field, not against the magnetic field.

If you want to understand it better, imagine that the outer magnetic field interacts with the lines of force going through the axis of the coil, and around it - the deformation of that field caused by the interaction induces then the alternative current in the coil. It does not work like a mono-pole or a dipole antenna, where a static wave builds on the conductor. It is a completely different principle. Hence the shielding effect of the outer layers is irrelevant here.

Sorry to disappoint you, but there is no coherer in the ELFE flashlight. Besides it, coherers are terribly inefficient, and not usable for receiving AM or lower frequencies (they were originally invented for the detection of Morse pulses). And most importantly, as already shown before, the strength of the EM field is simply way too low to harvest this amount of energy with a device of the size of the flashlight, even if you had an antenna with 100% efficiency. Regardless if it is a coherer, small loop antenna, ferrite rod antenna, dipole, monopole, yagi, parabole, or whatever else.

Wrong!  A coherer simply acts as a switch that conducts current in the presence of radio waves, and thus does not have the capability to demodulate, or extract the audio signal from.  The ELFE flashlight doesn't need to extract the audio!

In regards to the strength of the EM field being way too low to harvest this amount of energy with a device the size of a flashlight is also wrong.  Imagine a body that moves at velocity v in a region where there exist an electric field E and a magnetic field B. Then an electric charge Q inside the body feels a force Q(E + v x B). Thus, inside the moving body, the v x B field acts like the electric field of a distributed source. We are concerned here with the conducting media that move in magnetic fields. We shall see that they carry electrostatic charges whose field is just as important as v x B.

It's well known that conductors do not support an electric space charge; any extra charge deposited inside moves out to the periphery almost instantaneously (Lorrain et al 1988, p 75). However, few physicists realise that conductors do carry an electric space charge when subjected to a v x B field whose divergence is not equal to zero. If the conductor is isolated, then it also carries a compensating surface charge.

In other-words, the presence of RF causes the batteries to micro-weld or cohere in the ELFE allowing current to flow through the device.  This causes the batteries inside the resonant chamber to feel a force Q(E + v x B) which causes the batteries to decohere.  This induces very tiny vibrations within the resonant chamber which has an effect that is similar to the "Shake" flashlights.
