Longitudinal Wave Experiment to demonstrate Overunity

[d3x0r]

hi d3x0r,

I do ill-advise against putting a signal generator in the middle of the circuit.
Since we know longitudinal wave travels in a compress or  rarefaction manner in a medium in parallel formation.There are few youtube videos to shows this in the spring.

Imagine if you got a long spring as seen in youtube video where 2 end will be stretched a little.Then if you start from the middle by giving a quick to and fro ripple.The longitudinal wave would quickly travel on the left and right end of the spring and both waveform would return back to the center of the spring where you started and "completely cancel each other out if there is equilibrium achieved".

The waveform would be destroyed instantly and there is no chance for waveform to gain momentum from the "next input ripple" from the middle.

But.  I started with 4 in series (to the left) and it behaved as expected.... although I did still notice strange chirp signals (increasing frequency) on the collector itself.  When I added more modules to the right, the left was unaffected, but the chirp signals continued as extended to the right as more were added modules on the right.  (So the idea of plucking a spring in the middle is not a match for this)


THe transistors I was using were 2 17A 250V darlingtons in parallel... so it could drop 34A at a time... good for at least 300Khz
the coils are 4mH and the caps were 9nf; something like that... resonant frequency around 30kHz

Hi magpwr,

Please notice my answer on including capacitor losses for the simulation (Reply #25 in previous page).

PS: would you use DC coupled scope settings from now on...

Hmm maybe this time I'll work out an inductive driver for it instead and decouple the LMD network from the driver more

Hi everyone,

I have attached the waveform from my actual experiment which i took a few shots since there was a mirage of the actual waveform.

The actual circuit is running at estimate 2x of the input frequency.

Do you find it strange the waveform from my virtual experiment and actual experiment looks nearly the same.

I'm using small 474  250volt mica of course but lousy ESR since it's design for radio receiver likely.But produce cleaner signal compared to metalized capacitor.

Some lessons learned today 3" toroids isn't suitable for this job since few windings "9" to get nearly 1mH.But this translates to low voltage <30volts at output due to low winding count and "high" ESR for small capacitor which is designed for receiver.
nanocrystalline toroid produced even worst result at output stage due to lower winding needed to achieve 1mH compared to iron powder toroid.

Next stage waiting for ferrite rods to arrive to resume experiment.Since i would to wind more turns to achieve 1mH.In all case i'm sticking with 18AWG.

The capacitors at the top and bottom need to be paired and matched base on L/C meter reading to ensure longitudinal wave travels in parallel manner,just to be on the safe side before commencing experiment.

The higher ESR of the mica capacitor is damping ringing that you get with a low ESR plastic film capacitor.  That cleans up the waveforms nicely.  Depending on your point of view it may not be what you want.  If the idea is to maximize the ringing in hopes of OU, then the plastic film capacitor is better from an ESR standpoint.
