and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Now lets consider an inside out speaker.
Meaning a stationary cone-coil and the magnet instead moves.
Now invert an opposite (generating) cone on the other side.
If fired with 1/2 wave pulses - i would expect generation at both coils.
One for half cyle (off duty), and the other a full wave.
I'll add that my proposed "energy system" is a direct "energy generation opposing spending" since all speakers are spending energy, but at the same time are opposed by each other and also partially turn into generators. A "sqeeze" happens. If speakers are placed sequentially as you propose, the system may also be turned into opposition, but sinewaves are probably better. The problem with sequential arrangement is that acoustic waves of the first speaker won't reach the second cone much - they will be reflected by the magnet on the back of the cone. If I understand your proposal correctly. I do not really see how to make things better by anything else than opposing cones, with the frequency and distances tuned to create at least 90 degrees phase difference between generating and spending energy waves.


Audience amplification and thermo-acoustic fireplace examples have too much diffusion happening. My proposal requires exact resonant frequencies and high-enough energy (at least several watts on a SINGLE frequency). As far as I remember I've played them pretty loud, close to the level of obnoxious (loud acoustic sound is a problem of the system, but it can be minimized if enclosed in an insulating box).

I would not underestimate the fact speakers in my test were all connected to the same energy source, even if this may sound unimportant. We are in the field of loosely explored.


Here's why:

A "wave field" of sorts may be created by acoustic waves, so it's possible when a simple soundwave meets an opposing force, it works like a spring, affecting preceding fronts. A continuous soundwave basically looks like a train of compressed matter. More importantly, as the inspirational video above shows, the fronts "stay in place" like bricks, they do not propagate like a bullet. This is a bit another way to look at what happens in acoustics. It's "worm crawling" and not a "flight".

What i was interested in is pinging an object, record the soundwave then wire the object with laminated copperwire and pulse that waveform trough the copperwire.. would it fly? Break? Sound can break glas but what about copper wire on an object? Maybe on wood steel aluminium etc :P ???

Haha, sounds like sound-fiction. :-) But yeah, I get the idea like making a feedback of its atomic structure's sound. Electricity is not acoustics, there's no immediate coupling for any interaction to take place.

Yes there is a sound wave you can record with cooledit, you can see the ac waveform, put that into the wire
