This thread has been created to discuss the DFEM-Simulation of a Zero-point-energy Converter as proposed by prof Turtur in following article:

There were some clear doubts whether the model is correct as presented by Turtur in his original article due to too low sample rates.
E.g. as indicated here: http://www.overunityresearch.com/index.php?topic=738.msg11732#msg11732

Looking into this potential flaw, I agree that the sample rate of the original simulation is quite poor.
Sample rate definitely influence the reslults of the original algoritm, so this should be kept in mind.
Attached the sample rate of the last few periods of the energy in the external load resistor.

In addition I performed a simulation where I increased the number of samples to 10 fold and at the same time decrease the initial rotation speed of the magnet.
The results are attached as third and fourth picture.

What can be observed from this initial experiment with increased sample rate is that power is increasing.
Due to the limit of the maximum allowed nr. of samples calculations stopped in the still increasing power period.
I've asked Haithar, who developed the software that includes Turtur's algorithm, whether it is possible to increase the max. nr. of samples.
He will have a look at this, but indicated this is not easy to implement.

Fascinating....

Correct or not I find his work intriguing. When I have some time I'll compile his program and post the file on this site for those willing to try it.

Yes it is!!

For the "mechanical" part of the circuit why not use a
loudspeaker?  The voice coil/magnet arrangement
would seem almost ideal.

Speakers do have a resonant frequency.

To reduce losses the speaker could be enclosed in
an air evacuated (semi-vacuum) enclosure.

I am also looking into a ball shaped magnet that just rotates freely on a hard surface within or near an air coil.
E.g. this guy is doing some nice experiments that way: http://www.youtube.com/user/jonnydavro#p/a/u/1/SmxlNkLQ-Ps
There is a discussion thread at OU on this: http://www.overunity.com/index.php?topic=7113.0

I like the idea of a loudspeaker though!
(I don't know about my neighbors.... )

I have working source code from Prof. Turtur and a compiled WindBlow$ console application running.

The attached file is the source code and the executable.

The source file (MCPE.dpr) is a simple text file. You may read it with any text viewer/editor.

Even if you aren't a programmer, how the good doctor calculates should be evident and helpful.

I'm thinking about making this a full-blown WindBlow$ app so I can vary the constants and the variables but too many more important projects are on the table, right now

an air evacuated (semi-vacuum) enclosure.

Air pumped at resonance will work, it is called a "Helmholtz Resonator"
but perhaps there are better ways to store cyclic energy to harvest back amplified by resonance.



A small full range high power speaker for a car door as example,
as they are inexpensive and readily available as a starting point.

It has the spider and cone to handle and guide the oversized voicecoil already made for you.

Epoxy a properly sized spring to the visible end of the voicecoil,
and bridge the speaker's frame to the center to hold the other end stationary.

This concept is currently used for linear motion spring resonance refrigeration compressors
to obtain considerable power savings during battery operation applications.

Another would be to use the linear stroke of a speaker to modulate a paddle.

Take a rectangular aquarium collecting dust in the garage,
straddle the narrow width aspect with a shaft in the middle,
fashion a paddle that leaves about 10% space both sides and bottom,
attached the linear motion motor to the paddle and fill halfway with water.

We have all seen recovery of ocean resonance (waves),
but have not "Made" the resonance in the first place
in order to optimize it by frequency and dwell of stroke.

Springs are awsome resonance items,
and water is powerfull but slower.



But I popped these in as reference to the linear concept,
here is a rotary idea.

Run two long large pieces of pipe up a steep incline side-by-side,
put a positive displacement rotary vane or gear pump at the bottom
with the pump's in and out connected to the two pipes ends respectively.

Attach a DC motor/generator unit like a golf cart motor, etc. to the pump.

half fill each of the two pipes with water and use the pump's motor
to pump all the water out of one of the pipes to fully fill the other.

As a defined amount of power is used to shift the water to the other pipe
energy is both used as momentum during the cycles to complete it,
and stored as gravitationally recoverable force at the end of the cycle.

Now use a circuit to alternate between powering the motor,
and using the motor to collect the energy back into the battery.

A cyclic resonance will get more out than put in,
even though it should not by current physics laws.

If a rotary coiled spring similar to a watches mainspring was added,
to go with this threads LCR/Spring resonance persuit it might yield more.

The speaker and spring moving notibly fast is easy for us to visualize,
but much slower resonances like ocean waves get overlooked often.

Larger/heavier mass at a slower resonant frequency should yield more to harvest.

Very nice read, explains many motor designs from Newman to the "window" motor.

Takes a couple of read-throughs to get it all. Thanks.
