If you are a serious TPU builder, and follow these topics you may be interested in this proposal.
Let's have a TPU conference !!!
We can meet and show off our devices, have a few presentations, etc.. and who knows, I might be able to persuade a very special person to show up! ;)
Send me your email if your interested, or even if your're not, I would like to compile an updated list because I will be sharing my latest results through email only!
Sincerely,
EM
A conference by e-mail? Looks quite manipulative. This way only one guy or a group of manipulators decide whom to share, what and when to share any result. One can even steal someone else's ideas if not introduced to an open source on time.
I understand that there must be done something to change somehow the approach presented in this forum and invigorate ways to re-invent the TPU. But sorry, not this way. Beware inventors!
self-removed due to exasperated overuse of expletives...
No tickie,
no laundry.
Can't share,
take your ball and go home...
I would join your conference but I still doubts about it.
OOPS, I think I upset some of you.

Did you have contact to SM?
im in EM!
SKYPE?
works for me ..
if there any questions i could answer ... i most certainlly will do so!
and i would love to speek with sm ..
im pretty sure we spoke a time or 2 in the past ... unknowing on my part...
lol
set it up
w815!
sorry i'm afraid of massacre ;D ;D ;D ;D
Thank you for the many PM messages and the posts here. I understand the concerns some of you have, so we will video tape the conference and I'm sure it will be available online to those that can not or do not have the time to participate. This is all about open source, you can be sure about that.
Happy Holidays,
EM
Chainsaw ruleez.... Kill bill part 5... :P
Emdevice where are you located, I am in US I d'love to joint the group
I have been R&D TPUs for long time, but no OU on TPU yet, I have tryed a lots lots of design.
My most recent discovery is some mosfet with no dc input power can still conduct:
I have this very interesting circuit on mosfet that I have to share, I can't explain how its work!.
Circuit consist of 2x 10 T 22g coil on a 6" ferrite ring, one 2sk3565 mosfet, one cap, I feed the gate only with 100khz -400khz square sig at 3vpp 50% ratio.
I vary the freq and I got between the ground and the cap 12-25v! no DC use on the drain! the drain is connected to the coils and cap in series.
how can that be?is it free energy? is anyone want to take the challenge
BTW the coil does not have to be on a 6" ring a small torrid or even a rod will still create this phenomenon!.

Hi Erol,
MOSFETs can readily switch on between their drain-source electrodes without any voltage connected between their drain-source: they need only control voltage between their gate-source electrodes that is enough to defeat the so called threshold voltage.
So your 3V peak to peak signal gen can do this switch-on, because your FET type has a threshold between 2V to 4V, see data sheet here: http://www.toshiba.com/taec/components2/Datasheet_Sync//77/10779.pdf
I think the DC voltage in the 1uF cap is created mainly by the following process: the body diode (between the drain-source) rectifies the generator input which is able to couple through the 1 nanoFarad gate-drain interelectrode capacitance, (taken from data sheet) this diode is able to rectify whenever the FET is switched off, i.e. whenever the generator 3V AC is lower than the threshold voltage limit of the gate-source. Probably this would not give you as high DC as you found but once the capacitor has a few Volt DC in it then it serves for the FET as a supply voltage and current via the coil can flow as the FET gets on and off, hence some bemf can develope which may further increase the DC voltage in the cap.
So I do not think this circuit gives free energy... it is an unusual AC-DC converter, its energy input comes from your signal generator.

I have some experience using FETs and with a new device, I believe the gate leakage should be extremely low.
They do have a certain amount of capacitance on the gate, but actual leakage should be low. In fact it should be so low that just touching the gate can easily switch them on and they will stay on until you touch the gate again. It really depends on the exact time you let go of the gate due to the environmental AC in your body.
But just the static charge on the gate is enough to keep it turned on. That is where the name comes from "Field Effect".
If the gate voltage is exceeded, even by static charge (as mentioned above), then small holes can be punched through into the substrate and gate leakage will increase. (it's now damaged but still functional)
Hi Lumen,
Would like to understand what are you aiming at?
Could you explain how the DC voltage is created in the 1uF capacitor, please.
Thanks, Gyula

Guyla,
Well right now this particular setup (toroid and double coil winding) seems to be the interest of OU claims from many sources.
I was considering that if this was true then there should be a way to produce energy from nothing or what seems like nothing. In this case, one might think that a charge in the capacitor could be used to induce a field in the core where the back EMF of each coil would incite further charge in the capacitor and so becomes an endless loop. What may limit the charge is the fact that as the charge goes up, the frequency may need to change to follow the increasing saturation of the core. Yea, probably just dreaming, but since I have a setup very near this already, I will be trying this also.
Hi Lumen,
Ok, thanks, now I got it. Years ago I also tinkered with a similar circuit, though it had a 1.5V AA dry battery as the supply voltage, but I did not receive any extra output what was claimed, the circuit behaved as conventional EE theory describes it. I used exactly the same components he recommended. You can see the circuit here:
http://www.rexresearch.com/szili/szili.htm
His theory is this, quote from above link:
"When the electrical current increases, that made decrease inductance, and a reduction in inductance makes amplify the current… and so on. It is the effect of avalanche. This reduction in inductance has a certain limit determined by the electronic circuit. Once the stop of the avalanche, the process is reversed. Inductance increases and that made decrease the current… and so on. This return takes less time, because there is no extraction of electric output of the vacuum during this return. Normally, because of the electric losses, the avalanche does not start again without stimulation (ex: a pulse exceeding a certain value)."
In Aragox's schematic the gate of the MOSFET is floating, normally this is not recommended (a resistor is needed to place across the gate-source electrodes) but probably his pulse generator gives out a +/-1.5V AC pulse with respect to the gen ground or common output when it is set to 3V peak to peak output and with this condition the gate source capacitance can discharge and the switch off is ruled by the square wave and does not happen irregularly.
If Aragox tries to load the DC output with even as high loading resistor as 20-30 kOhm, he would find the 10-15V DC across the capacitor would go down significantly. Would be good to read his findings, including how sensitive the circuit to varying the input 3V peak to peak gen pulse amplitude.
Thanks, Gyula
@aragox
I think @gyulasun is very right. As a control, just put the square wave positive directly onto the first coil (no negative pulse) and measure at the output. High frequency pulsing is very tricky because you think everything on the circuit is causing the effect when in many cases, the same effect is available directly. Producing voltage is very easy in such cases.
@EM
Where the F have you been.
Hi All, Thanks for the reply.
I did try few suggestions, Gy, the DC straight to the coil did give me only 0.17 vdc at the out
same parameters input.
but at several hertz (low freq) the in= out.
I did two test at 0.4vpp Sq 50% ratio, and 1.5dc on top of the 0.4vac pp
Note on the Pictures I am taking the output at the Drain.
0.4 vpp should not conduct the mosfet!.especially passing the diac threshold :-\
maybe several of this circuit in cascade might increase the output.
an other thing I don't mention any current value. should be in the ma range.
I am going to invest more around various similar design.
I guess my test is to get a very low voltage at the input and get kw's at the output for self power gen.

Hi Erol,
I edited a little your previous schematic to show input waveforms and that no need for the input capacitor, you can directly connect the gate electrode to the output of the square wave generator. Both A and B waveform I drew are ok for driving directly the FET, the waveform B that has no negative portion would be good also for wattsup suggestion when you omit the FET and the generator output would go directly to the coil input where the drain electrode was earlier and the generator ground to the 1uF's cap negative point of course as earlier. Try to control the output voltage level of the generator, both in case with the FET and without the FET, to check how the DC output depends on the input AC amplitude.
With the FET in place, you may find a generator output amplitude beyond which the DC output would not increase any significantly but a little. IF your FET's gate-source threshold voltage, V
TH is around (say) 3V, then the optimal square wave amplitude may be between 3-3.5V maximum with respect to the zero line, waveform B in the drawing, and 6-7V peak to peak if you have waveform A coming from the generator.
In case you do not use the series capacitor between the generator output and the FET gate, then you drive the FET from the generator low impedance output, the FET self capacitances can charge up and discharge more rapidly, and when you use the series capacitor then you drive the FET with a higher impedance (the 180nF or the earlier 1uF coupling isolates a little) and the FET self capacitances can charge up or discharge slowerly, all this affects the output DC voltage.
Please check how much the DC output voltage across the 1uF capacitor is loadable: when you measure say 16-17V DC output, place say a 10kOhm resistor across the capacitor and watch the voltmeter, ok? This way you can judge how the output is loadable and how much hard work you need to do for getting higher output power.
rgds, Gyula
NOTICE 1: If you place the LED to the drain as you show, then keep in mind that it has a forward voltage drop of 3.2V if it a white or a 1.6-1.7V drop if it is a red LED, this means the DC voltage across the 1uF output cap cannot be higher than the forward voltage drop of the LED, ok?
NOTICE 2: what kind of diac do you speak of? In your schematic there is nowhere any diac... and if you mean it is in the FET, forget it and study the equivalent schematic of a power MOSFET.

I forgot to mention, if you pulse directly onto the coils that only has 10 turns and 10 turns, you then have to reduce the pulse width to around 10%. In many cases 50% pulse width will just kill the effect, but using the 50% on your present circuit may work because the device is absorbing some of the width. You are just using more input energy. Pulsing at only 50% duty width is like inspecting the ocean when you can only go knee deep in water. You have to be able to adjust that parameter otherwise you miss out on learning so much more about pulsing.
ok , did some measurements,I plugged the gen directly to the coil, now we have a regular LC Circuit.you think...
Step1: 3vpp SQ no DC components, 10% ratio, the output on the cap is :
-from 1hz to 10khz Out =in as an image of the input signal, but goes down in amplitude as we approach the 5-10khz
-and 10khz to 20khz the signal is reduced to zero!.
Step2: 3vpp SQ with 1.5vdc 10% ratio, the out is:
-below 10khz the out = in as above
-10khz and up we got a straight line at 1.5vdc
so if dc show up at the input it is transferred to out directly that's all
the mosfet configuration gives some realty different results!
BTW I did not see ANY resonance freq on the whole range!
I am back on the SM open frame configuration TPU, I did increase some number of loops coils, I got more currents on the output by cop2 when the out is in short cc. the input current does not change at all.
very promising!

I just noticed my last post I made a typo mistake the range is 10khz to 20Mhz not 20khz.
sorry
