I'd like to point out at Tesla Coils. If you look at the discharges differently, you'll immediately start seeing that surrounding space is an ocean of electric energy and it has "ground" contacts everywhere. The energy emitted by Tesla Coil just vanishes into thin air!

Here's a bit of research on Tesla Coil in vacuum. Obviously, the energy "evaporates" into thin air despite there are no ions in the atmosphere: no ions - no charge carriers to accept the energy. Funny, isn't it? Except in deep vacuum it looks like a corona, not a discharge.

This device looks believable: https://www.youtube.com/watch?v=nnAE0hqgH6Y


While it's not about acoustics, I think the underlying principle of these devices is similar: creation of "sqeeze" by means of creating opposing forces of the motor and a flywheel.

Grebennikov is not well-known beyond Russia, but this scientist discovered the "secret" of gravity force. In some interviews, however, he admitted stopping research, because of unknown geopolitical complications of gravity devices. In light of my idea outlined above, a wing of an insect may represent the outlined device.

Very nice DIY device involving acoustical speaker. Reacts fluidly to bulb load meaning feedback aspect is in full effect. The construct has a pretty low "fake factor" in my opinion. Also, the device operates longer than what start-up battery may allow; visual rotation of the board rules out external powering via air.

This is my version.

Here's an overview of how such a system could work:

A piezoelectric material is placed inside an audio chamber or resonator, which is designed to amplify and sustain a specific frequency of sound wave. The size and shape of the chamber, as well as the material properties of the piezoelectric material, would be carefully chosen to maximize the acoustoelectric effect.

The electrical signal generated by the piezoelectric material is then used to trigger a back EMF coil loop,The feedback loop created by the back EMF coil loop will help sustain the sound wave within the chamber, and thus the acoustoelectric effect.

the system is first triggered by an external force, like a tap on the audio chamber or a burst of sound. This causes the audio chamber to resonate and the piezoelectric material to vibrate, generating a voltage spike that is fed into one of the coils (let's call it the "trigger coil") of the back EMF loop. The back EMF loop consists of two speaker coils, which are also used as part of the audio feedback loop. As the back EMF loop generates a voltage spike, it causes the speaker coils to vibrate, which in turn keeps the audio feedback amplitude strong in the audio chamber, sustaining the vibrations of the piezoelectric material.

The audio tone generated by the speaker is then fed back into the audio chamber, where it reinforces the original trigger, causing the speaker to continue vibrating and generating a sustained feedback loop. This sustained feedback loop keeps the back EMF and audio tone going, allowing the system to continue generating electricity.

So in summary, the speaker has two jobs in this system: (1) to generate the initial voltage spike and (2) to vibrate and generate an audio tone that sustains the feedback loop. By using the speaker in this way, we can create a self-sustaining system that generates electricity without the need for an external power source. The sustained sound wave within the chamber will continue to cause the piezoelectric material to vibrate and generate electrical signals, which can be used as triggers for the back EMF coil loop. As long as the feedback loop is maintained, the system should be able to sustain itself without any external power input. The output of the back EMF coil loop could be used to power a load, such as a battery or electronic device.

Overall, the key to making this system work would be careful design and optimization of the audio chamber, the piezoelectric material, and the back EMF coil loop. The system would also need to be carefully tuned to the resonant frequency of the audio chamber to maximize the acoustoelectric effect. The audio chamber needs to be designed to resonate at the same frequency as the speaker coils' optimal frequency, which is also the frequency of the audio tone that triggers the back EMF loop. This resonance will amplify the audio tone and maintain the feedback loop, which allows for the back EMF to bounce back and forth between the coils and generate power that can be tapped into. The resonance can be controlled and maintained by adjusting the size and shape of the audio chamber and the frequency of the audio tone.

One advantage of this approach is that it doesn't require any external power source or battery, making it self-sustaining. Another advantage is that it could potentially be made from low-cost materials, such as piezoelectric ceramics and simple audio speakers.Traditional loudspeakers can suffer from significant energy losses, and piezoelectric transducers can have relatively low efficiencies, the proposed system is not based solely on either of these components. Instead, it combines the unique properties of piezoelectric materials and audio chambers to create a system that is designed to maximize the acoustoelectric effect and minimize losses.

In addition, the system utilizes a back EMF feedback loop to sustain the sound wave within the audio chamber, which further increases efficiency. While it's true that no system can be 100% efficient, this approach has the potential to generate usable amounts of electricity without an external power source.
the self-sustaining loop is designed to have a net positive energy output, meaning that it produces more energy than it consumes. This excess energy can be used to sustain the system, even if there are inefficiencies in some parts of the loop. While it is ideal to have a self-sustaining loop running at maximum efficiency, it is not necessary for the system to sustain itself. The back EMF spike is just one part of the system, and there are other means by which the system can generate and replenish energy if you understand how this works.

Thanks for your presentation, Joel. I think it must be a lot simpler like placing two piezo-electric speakers very close to each other and adding some not very elaborate circuitry. The only thing that should matter is force created orthogonally to force that drives another speaker. From my experiment, the power surge happened outside all circuitries, so it's very possible that "energy from space" may appear/channel from a place that you may not expect it to appear at (back EMF in your explanation I assume). I even think that the whole system happened to raise to another voltage level, hence the surge happened (voltage relativity of some kind).

Having to refresh my memory of the exact definition of entropy I found this:
"a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system."


So it would seem 'no' is the answer unfortunately.  I could be wrong but that's the way I interpret it from the above definition.   It is certainly possible that this 'official' definition is something 'they' are using to hide from people the potential energy available there.
