COP 17 Heater | Rosemary Ainslie | Part 2

[ashtweth]

And more tests will be posted here soon with a good scope guys to back up the data from US Panacea, despite me saying previously that its a modified version of the circuit it IS the same circuit, and full credit to Rose, Glen and ALL for sticking to the "faith" and emulating what Rose has been trying to do.We have been through many ups and downs but we are still here doing the good work, and Rose is doing well, thanks to Bart and others for flowing with the goals.

There will be more data from Rose's contributions and the open source community posted here in a a month or so, our ROSE circuit goes in to supporting all in a few weeks, i am half way through a thank you and validation/ video production with all OUR themes.

Respect to ALL

next experiment results

Hi all and many thanks for your kind support !
i'm happy to announce a progress in the Ainslie circuit replication - not only finding more resonance frequencies (200/272/313 khz) but also some negative voltage across the shunt (for part of the time) ,which might indicate a COP >1, as Rose said before.
i have difficulties getting the load resistor to higher temperatures than 34 celcius, and also measuring the mean voltage (true RMS) across the shunt , but we'll manage these soon, i hope.

The attached images describe the shunt voltage (upper channel in the scope), and the load resistor voltage (lower channel). I got far as 700v on the load resistor (200v per div.) and the shunt got spikes of down to -3v (1v per div).
Note: the ground level of the shunt channel is the bottom line of the first square on the screen from the top of it.
But the temperature rise of the load resistor did not exceed 33-34 celsius at all times ! while the MOSFET (with my heatsink) rises upt to 47-49 celsius. I had air condition in the room , I think the air temp. was about 22-23 celsius.

SHUNT voltage - I also had 2 RMS voltage readings with a multimeter, but I'm not sure they are correct (since it is not designed to read at these frequencies): AC = 2.6mv avg., DC = 43 mv avg. so after my calcs. Of the current , I measure the wattage of the load resistor as 1.3 milliwatts (AC) or 0.3 watts (DC) accordingly.

All these results are for the image: "gad self oscillation #2- 700v, 200khz, shunt – zoom.jpg."
(But other images are close to these results also, of course)

Also, my IR thermometer (basic one, 50-70$ value) shows different readings of heat across the load resistor – between 27 and 33 Celsius. Is this right ? i consider to use a "water thermos" instead (as I told you before, but I started with a simple IR thermo reading)

My scope got broken in the middle of the experiment , so I switched to an older one (the image is from the older).

Very well done that you found these varied frequencies. It is a fact that this result is NOT dependent on any single frequency and I'm so glad you were able to show this. It certainly is in line with our own findings.

I have difficulties getting the load resistor to higher temperatures than 34 celcius, and also measuring the mean voltage (true RMS) across the shunt , but we'll manage these soon, i hope.

Gad, this is not significant. What is more important is to ensure that the energy loss at the battery is zero or thereby. Then the heat is 'jam' so to speak. But I suspect there are still more frequencies to explore.

But the temperature rise of the load resistor did not exceed 33-34 celsius at all times ! while the MOSFET (with my heatsink) rises up to 47-49 celsius. I had air condition in the room , I think the air temp. was about 22-23 celsius.

Again - subtle variations on each circuit can still make exponentially large changes in the results. But - technically - the heat over the FET is also a gain to the system and can be factored into the final calculations. If you can weigh the 'mass' of your sink and fet compared to the weight of your load resistor you'll get a 'ball park' number that would be roughly appropriate. I suspect that fine tuning will get you to higher 'heat' values. You may want to explore slower frequencies - but it's your choice. I have found that it's best to let the experimentalist follow their own intuition in these matters.

SHUNT voltage - I also had 2 RMS voltage readings with a multimeter, but I'm not sure they are correct (since it is not designed to read at these frequencies): AC = 2.6mv avg., DC = 43 mv avg. so after my calcs. Of the current , I measure the wattage of the load resistor as 1.3 milliwatts (AC) or 0.3 watts (DC) accordingly.

It would be wonderful if you can get the use or loan of a storage scopemeter with an appropriate bandwidth. Results would then be unarguable. But we're in your capable hands here Gad.

Just know how grateful I am that you're working on this and again, a real tribute to your own experimental skills. It's not an easy waveform and although - on the face of it - a very simple circuit - there are subtleties in measurement and skills in adjustment that really are not for the faint-hearted. You've done very well indeed. Congratulations Gad. As mentioned, if you can get hold of that scopemeter then you'll be in the happy position of confirming these measurements. Certainly on the face of you you're in positive territory.

Hi all.
finally i got the load resistor built and bought a high voltage probe (specs - as i wrote before).
Experiment description:
load resistor (see image) - NiCr 80/20 wire, gauge 20, spacing of 1-1.5mm between each wire. using teflon rod, diameter 34 mm - but with a carving of 1mm depth - so inner diameter is 32mm. 48 turns = 10.5 ohms resistance.
MOSFET - i glued a heatsink to it (not shown here) - taken from an old pc motherboard.
Wiring - Power circuit : 1.2m x2 between 24v batteries to load resistor and to the shunt, approx. 14 gauge wire, single copper thread (standard power electricity wire used for 220v in your house, i think). other wires are 10-35 cm (not shown in the images).
555 timer circuit: 24 gauge wire, single thread.

scope channels (see in the images):
ch 1 = MOSFET Drain leg (load resistor spikes).
ch 2 = gate pot. leg to 555 (the 555 output signal)

experiment process: first of all, in order to get the required 3.7% duty cycle with 2.4khz base frequency, we disconnected the power circuit from the 555 circuit. otherwise - we could not reach under 8% duty cycle !
after disconnecting , we managed to get about 3% duty cycle and 2.4 khz freq., using the following potentiometers values:
2k ohm pot. = 194.5 ohm (called the "duty cycle pot.")
10k ohm pot. = 9.87 kohm (called the "frequency pot.")
100 ohm pot. = (called the "gate pot.") - value does not matter at this stage (since the gate is not connected to the 555 timer circuit) ! we'll deal with it later on.

after getting the required freq. + duty cycle, we connected the power circuit to the 555 circuit, and adjusted the 100 ohm pot to its lowest value (almost 0 ohms). the spikes on the load resistor were the biggest. after tuning the gate pot. to 0.8 ohm, we got about 420 volts (see in images - ch 1) and we got an instant self oscillation of ~318 khz !! we also got a lower spike in the same freq. of about 150 volts (see in images - ch 1 too).
the 555 signal was distorted due to the oscillation - we think (see ch 2 in the images).
so thats it i think. but i did not get any "aperiodic oscillation" (to my knowledge...).
what is the next step in order to get ready for the energy measurement and expecting COP > 1 ?
how to get the aperiodic osc. ? is it needed or what we got is enough ?

thanks to you all for your kind support,
Gad

Hi Gadh,

How did you manage to have that resistance wire 'behaving' itself and keep it in place on your Teflon base cylinder? I'm planning to make a new resistor with a bigger coil diameter since I don't have the same results you have and I don't understand why not. I used tape to keep the wire in place but it seems to me you have a better way to do that.

Cheers,
B

[gadh]

Hi Bart.
i managed to keep the wire in place by doing carving/engraving of 1mm depth on the teflon rod by a machinist. the outer diameter is 34mm, inner diameter 32mm. see in my images of the load resistor

So the wire is actually not glued but pinched inside that engraving? I had the experience that this wire is very stiff and stubborn and will not stick in place just like that after being bended around the base cylinder. That’s why I used tape and others used liquid silicone and stuff.

Cheers,
B

[gadh]

yes, its piched inside. i myself failed to wound it around the rod so i payed to a machinist -its a cheap work (i think in your place too...)

[b4FreeEnergy]

@Gadh,

Nothing is cheap where I live but it's an excellent idea. See if I can find somebody who can do this for me.
Did you do some further measurements meanwhile? Any progress?

Cheers,
B

[gadh]

I started measuring the load resistor temperature but then my scope went broken. i'm now getting another one, will update then.

Bart, guys, all,

REALLY GOOD NEWS. There was a hiccup in our progress of the application at that aforementioned institution. ALL PROBLEMS HAVE BEEN RESOLVED ENTIRELY. Tests will now be scheduled and hopefully all will progress and that at speed. We are working on the resistor design and thereafter - God willing - it's all systems go.

It is to be hoped that there are NO FURTHER problems.

Bart, I'll contact you soon. Apologies for not doing so earlier but, frankly, I was too dejected to deal with things. Thank you Bart and thank you Gad for your wonderful work and your positive attitudes. Without that much I think I would have been feeling somewhat suicidal.

It seems that truth will always win even if one must fight for it. I take comfort in the fact.

[gadh]

Hi Rose.
can you elaborate on which problems were solved ? how much COP did you get in the latest experiments of the water heater ?

[b4FreeEnergy]

This is really good news! Apparently common sense took the overhand at last regarding your request to repeat the measurements in well defined circumstances and plenty of skilled people at hand …

I found it hard to believe anyway that the people at that university can be influenced so easily and don’t think, read and ‘measure’ for themselves. I’m convinced as well you did not let them ‘escape’ so easily Rosemary, you would attack a fully armed harbor on your own in a speedboat …

But hey keep us posted and all the best. Don’t come back with COP’s less than … well 100 will do!

Mazzeltov,
B
