Its great we are talking technology again instead of flame wars .I apologise for any small part I may have played in this , I usually pride myself on not rising to the bait .And thanks Rosemary for acknowledging that I was the first to suggest biasing the gate with a battery . I know that I walk among giants on here ,so its good to know I can make a small contribution .
           On a more serious note . Given the bias battery , the whole circuit is mega simple . Maybe we should now look at it as a simple radio frequency oscillator [with special effects] .An oscillator has been defined as an amplifier that feeds its own input .To work , an oscillator needs two things . An amplifying device [the mosfet] and a feedback path .We need to fully understand this feedback path/mechanism in order to make the oscillation controllable and reliable . As Rose suggests , the wiring may play a [huge] part in this . Since most RF oscillators are not overunity ,we need to identify what is different here . I think it may be the use of a power mosfet operating at higher voltages than would normally be used in an oscillator .Also looking at the photo of the latest apparatus in Hartiberlins post ,there appears to be only ONE mosfet . Rosemary , can you please confirm this ? A final thought .When the circuit oscillates at 1.5 Mhz you would hear it on a medium wave AM radio .Also , If I was building a RF oscillator for 1.5 Mhz , the coil would have probably 100 turns on a ferrite rod . MUCH more inducatance than Rosemarys heater .As the circuit stands , I would expect it to oscillate at about 100Mhz plus or minus 50% .

Sorry all - especially Feynman.  Those waveform downloads defeated me.  One of the team is sorting it out.  Hopefully I'll be able to post it across later tonight.

Neptune and Magluvin - there's nothing to apologise for.  Personally I'm delighted to see some kind of resistance.  I'm intrigued that this technology has been hounded at all.  And it seems that the latest affront is that I DARE to suggest any revision to the status quo.  Hamburger has gone on record as having coached Bill Gates in their formative years.  That was when his nascent genius was rampant.  Golly.  It seems one may not, under any circumstances, confront classical theory unless there's some evidence of this brilliance.  And therein lies the problem.  I have none.  That's the truth.  Very much your Mrs average.  So Neptune - if you're walking with Giants then I'm absolutely not in that party.  I'm only walking a few steps behind you.

It's a wonder that our quantum physicists ever survived their own attack in those early days.  It's some kind of vicarious comfort to know that even Heisenberg was laughed off the stage.  And also a comfort to know that he and Bohr had a hard time of it promoting quantum physics in the early days.  LOL.  Not that I'm in the same class.  My own proposals are WAY more revisionary.   :o

What really raises the smile is that Poynty has assured me that any reference to being an IDIOT SAVANT - has nothing to do with me.  In fact it appears that I'm rather presumptuous in assuming that my IQ could even be classed as IDIOT.  Golly.  I think the next step down is MORON - if I remember my phychology 1 lectures correctly.  It seems that I'm hopelessly dysfunctional as well as delusional.   What can I say?  And when I see how hopeless I am in finding my way around a computer - then I'm actually inclined to agree.

Anyway - onward and upward.  It's all in the public domain.  Not sure that the readership is quite as high as Cat's count - but it's robust.  Which means the news is spreading.  And that's all we care about - at this end of Africa.  Many thanks for the good wishes Cat.  I'm enjoying a rare sense of freedom from attack - but I'm still braced.  It's nowhere near finished yet.

Kindest regards,
Rosie

Guys - Here it is.  Thanks to Evan.  Not sure of the order of that upload.  I'll comment when I see if they've got up OK.  I've added some that aren't in the report. 

OK 1st 2nd 3rd and 4th.  All showing zero discharge from the battery and wattage dissipated at plus/minus 6 watts.  Did a whole lot to show that it's not frequency dependent.

5th and 6th - runaway temps - not less than 44 watts.

Channel 1 - shunt
channel 2 - battery
channel 3 - gate
channel 4 - drain

Math trace usually shown on D.

Just noticed that the math trace on those heavy duty numbers - are shown on B - I think.  Just keep in mind that the 'red' is calculated as the instantaneous product of the voltages across the shunt and the battery.

EDITED.

Another edit.  Apparently the video will be ready tomorrow.  I'll attend to Feynman's questions later tonight - else tomorrow after lunch. 

Thanks guys.

Just another question
can you describe the methodology in detail of calculating the heat generated. If I understand correct you use air rather than a fluid
Kind Regards
Mark

Hey Rose

Just something I had discovered a while back and wanted to know if you think on the same lines.

We hear a lot of talk on BEMF or Counter EMF.   
Well what I have seen is, if you apply current to an inductor then release the current, you can capture a continued current from the inductor before it goes bemf.  I call it FEMF. =]
In a lot of literature, it is said that the field collapse is what creates or generates bemf.
But from my experiments, I find that the collapse, from an induced field, produces current in the same direction as the current that induced the field initially. Only when the field collapses and then goes reverse, NS to SN, by bouncing off of the coils self capacitance, is a reversed voltage produced.
So I see the inductor as a flywheel (opposition to current change) of sorts. Add the self capacitance, and it becomes an off balance flywheel, or a tight springed pendulum.


Take for example a relay where a diode is used across the coil to prevent any self induced voltages from escaping from the coil into other circuitry, as said to eliminate"bemf"
The direction the diode is in, where it doesnt conduct input to the coil, when the current is released, the diode then conducts current that comes from the coil, in the same direction through the coil as the original current sent to the coil from the source. Flywheel.  =]

Just wanted your opinion on this, as I think there are many that have a misconception as to the hows and whys of BEMF.

Thanks for your time.  :-*

@ Magluvin. I think you could be right . Look at a diagram of a bipolarNPN transistor with a relay coil connected between its collector and the positive rail . There is only one way round you can connect the diode across the relay coil , and that is with its arrow pointing towards the pos rail . If you connected it the other way it would short out the relay coil preventing it operating . So as you say the "FEMF" from the coil when the transistor switches off , must be in the same direction as the current flow when the transistor is switched on . So in my opinion you are correct .
            A fact I have just learned .In the type of mosfet in this cicuit , as long as the gate is biased positive , conventional current can flow in either direction through the drain-source chanel . So when the circuit oscillates , current can flow from the load resitor through the mosfet and back to the load resistor in alternate directions . I had sort of assumed that the path through the mosfet was a one way path .We learn a little each day.

Thanks Neptune   ;]

That is a very interesting observation on the fets.

It seems as though many good things are coming out lately. I wonder if Japans situation is helping more to come out, before its all too late.

The bemf thing was a shock to my system 25 yrs after electronics school.

Hi Stefan,

A simple substitution of Caps for Batteries will conclusively show whether the anomaly is reliant on the chemical properties of the Battery Cells. We cannot know this until it has been evaluated, we can only assume that Caps will not work. I believe this would be an important simple test to confirm the anomaly is present only in chemical cells.

RM :)


yes, but I think also the batteries will discharge after some while.

But the important fact is, that only maybe 6 Watts or less are drawn from the battery,
but 40 Watts of heat are produced at the load resistor and due to the backEMF pulses the battery´s
ions are too slow to respond so it holds much longer and gets more capacity
as the backEMF pulses activate deeper lead layers and generate more
battery plate surface inside the battery.

Hitting some NiMh AA batteries with BackEMF pulses I was able to almost
tripple the capacity of my NiMH cells this way.

The same is true for the Bedini charger-energizers...


Regards, Stefan.

Hey Stefan

that is very interesting on the nimh batteries.  ;]

I have 3 electric bikes, 1 is a tidalforce m750 which uses 30 D nimh cells in the front wheel hub. 
They are ready for change. Do you think I can revive them this way? Or even better yet, get more than 20 mpc  miles per charge after treatment?

Sorry  to be off topic but this seems to be very important to anyone using these batteries, as they are $18 each, for the good ones. =]

Thanks for the info

Sure !

Just pulse them via a Joule Thief or use a transformer
coil with a relay for the make-break of the current.

The BackEMF pulses will revive them perfectly and also
put a great charge into them.

But only do this with Lead Acid and NiMH.

This will not work with Lithium batteries
as these are built different and
can NOT be charged like this.

But with NiMH batteries normal dc current chargers are a waste,
cause they always make the batteries after a while unusable.

Using BackEMF charging is a great way to always keep NiMH batteries
fresh and get them more capacity.

Regards, Stefan.

P.S: Yes you will get more than 20 Miles per charge,
if you charge them up with good BackEMF pulses.

YOu only have to watch the batteries, that they don´t get too hot
during charging, otherwise they dry out and this is the only way you can destroy them
this way.

So use BackEMF pulse charging this way, that they don´t get too hot to
hold in your hand, mildly warm is okay, but not too hot.

So reduce your pulse frequency, if they do get too hot or use a smaller coil
which stores less energy or use a different on/off setting ( PWM ratio for the input current
into the coil).

Thank you Stefan. =]

I have to take the hub apart to do this as there is extensive circuitry in both wheels.  I cant even fully drain them either because of this, as nimh do have a memory thing like nicad, just not as bad.

Very good, will try and report as to the outcome. ;]

Magluvin your are welcome.

Yes, take the NiMH batteries out and try to recharge them
with a bigger joule thief style BackEMF charger.
Instead of the LED you can connect your NiMH batteries.

The Voltage Spikes without the batteries should be at least 20 Volts Higher
than when the batteries are connected.
If you connect all NiMH in series to the output, that means, if you have for instance a 36 Volts
NiMH pack you should at least hit them with 60 to 100 Volts positive voltage spikes,
so this gets effective.

Please keep attention to the temperature of the battery pack
and only charge them this way, if you are near them and not let them
charge unattended.


Regards, Stefan.
