Rosemary Ainslie circuit demonstration on Saturday March 12th 2011

[Rosemary Ainslie]

Hi Neptune - this is 3rd time I've tried to answer here and keep getting called away.  Hopefully this time I'll finish this post.

Hi Rosemary on this beautiful spring day in the UK .I am a little bit confused here due to info overload .
1 . In the photo you show of the custom made element that fits in the canister , there appears to be only one Mosfet .Is this correct and does the circuit show overunity with only one mosfet?

We started with 1 MOSFET.  We only got the typical transitional spike.  But we were well able to get INFINITE COP - here defined as MORE energy returned to the supply than delivered.  We also got some impressive heat values dissipated.  But at 100 degrees and upwards we stessed the MOSFET.  I had nowhere to report all this because I was banned here.  I kept trying to hint at this on Poynty's forum but got a broadside missile attack from Pickle - and gave up there altogether.  Deregistration was urgently required as Poynty advised me he was NOT prepared to moderate this.   I only mention this because there was never sufficient reporting about all this.  And why I'm mentioning it at all - is that I really need you guys to understand this. THERE IS ABSOLUTELY ALWAYS THE POTENTIAL TO GET that resonating frequency and it can ALWAYS be optimised to MORE RETURNED THAN DELIVERED which is - by definition - COP infinity.  Unfortunately to prove this you'd do better with those zut oscilloscopes.  I've been hopelessly spoiled.  I've also learned that a functions generator is JUST FINE.  Was not sure about this.  But they keep a really clean waveform.  The 555's tend to lose that clean resonating frequency - by comparison.   

2 Are you saying that the circuit works best with 5 Mosfets in parallel , 4 of which have their source and drain connections reversed , or all 5 have these connections reversed .

On our circuit we have 4 reversed 1 not reversed.  But NOTA BENE Neptune - or we'll be back into really confused territory.  It is the gate and the Source that were transposed.  Not the gate and drain.  That's possibly important.  I've never reversed the gate and drain. 

Perhaps when you have time , you could show a revised diagram showing the optimum arrangement

I'll ask one of the guys to do this.  But they're all working.  So give me a few days.  But - effectively - it's exactly as you see it on that report.  Just with the transposition of 4 MOSFETs in parallel.

And thanks for the good wishes.  I must say - I'm glad it seems that I'm forgiven for withholding all this.   I really didn't want to bring it to focus until we'd had the results accepted as anomalous.  That waveform - regardless of it's efficiencies which are considerable - just SHOULD NOT be possible.  Certainly NOT within classical paradigms.

Kindest regards,
Rosie

Thanks rosemary for making time to answer my questions . These answers pave the way for more successful replications . And in the interest of politeness and good manners , thanks to Point99 for the diagram .

Rosemary, I'm following along quietly, have some stuff ordered but my main 'must-have' is still a decent function generator.  I really envy those guys States-side as there is tons of kit available on eBay with dirt-cheap shipping.  But it looks like I'm going to have to order one from China, but with a few 100 $ of stuff already in transit from there, I'm waiting to see if Customs here will be out to screw me financially.

Anyway, main purpose of post, a few questions that I am confused over.

1:  If as now seems to be the case the mosfets are not in parallel, how exactly are they configured?  This is kinda important!

Hi Sprocket.  I think this is answered above.  Four in parallel with that transposition of the Gate and the drain.

2:  When you blew the 2 mosfets, you admitted that you had a problem reproducing the 'effect'.  With some effort you got it going but didn't explain what the difficulty was.  If you have problems getting it to operate, what about the rest of us!

LOL.  No.  That was just my own idiocy.  It was just a question of pulling out the 'off set' button on the oscilloscope.  It's just that the guys who tried to resolve this never saw the circuit with the functions generator.  Their trouble shooting was on the circuit itself.  I'm absolutely satisfied that if I can do anything then - good gracious - JUST ABOUT ANYONE can do it.  LOL.  And tuning those circuits to get those delicious resonances.  That's really easy.  And it's fun.

3:  How much heat is generated by the mosfets?  Those are pretty hefty heat-sinks you are using, if you don't have an accurate way of measuring the temperature, could you at least estimate their running-temperature.

They don't get too hot.  Just I blew a couple when we inadvertently got into those heavy duty cycle modes - and then the voltages spiked.  But they handle 800 volts comfortably.  In fact I think those IRFPG50's can go as high as 1200 volts.  I'm open to correction.

4:  Have you since tried adding additional external shunt-diodes to protect the mosfets - presuming it was over-voltage that took out your 2 mosfets?

No.  Not yet.  I've just run a few tests to get the thing back up and running.  But I'm getting some new functions generators.  Still something wrong with this latest one as we can't get back that 3 minute interval between switching.  Apparently they're finding something even more sophisticated.  But I'll know more tomorrow or thereby.

Always a pleasure Sprocket.  And good luck with sourcing that functions generator.  I'm not sure why you guys don't perhaps try and get something from your technical colleges.  It's a way of 'spreading the word' so to speak.  And you'd be pleasantly surprised at how accommodating they are.  Anyway.  Good luck with your tests.  And PLEASE.  THINK APPLICATIONS.  There's really no need to keep trying replicate any of this.  The results are just so conclusive and so repeatable.

Kindest regards,
Rosemary

B is common ground.
positive Voltage of Function Generator Q1 switches ON Q2-Q5 swtiches off , because GS signal there is negative

negative Voltage of Function Generator Q1 switches OFF Q2-Q5 switches ON.
Now Function Generator is able to feed energy into the system during the off-phase !! . No  , this diagram should not be like that.Therefore no decay

[teslaalset]

So, if Q2-Q5 are 'on' the battery voltage (approx. 70V) is connected to the 0.5 ohm restricted input of the signal generator with just the heating element in series?
Must be quite a robust signal generator.....
