PhysicsProf Steven E. Jones circuit shows 8x overunity ?

[nul-points]

NP -- I am studying your circuit with interest, and learning.

I agree with what you are doing here and look forward to your results.  Thanks for taking a close look at this, and for innovations in "harvesting and recycling the [output]" which is the most difficult part of the evaluation of the circuit. 

Best wishes for your success,
Steven

thanks for your encouragement, Steven, appreciated!

it seems that you're comfortable with the fact that i'm not attempting a replication here, merely looking at one possible approach for you to try, if you wish, when you feedback the o/p of your circuit to the supply

hence, i'm not (yet) listing component values and probe points, etc

i tried a few 'variations on a theme' with the feedback arrangement, before leaving the system to run overnight, so the battery depleted some more, as a result of these preliminary tests
(the new pulse width is approx 35uS, at 182Hz repetition)

i could see from the voltage decrease over just a few minutes, that there was little effect from the feedback with some configs, but one or two looked better than others, so i settled on one (as shown above, but with an additional schottky, D2, in reverse polarity across 0V and Vee) to leave for the overnight run

at 03:00:
Vbatt: 1.22V
Vcap: 2.39V

at 08:15:
Vbatt: 1.22V
Vcap:2.38V

i'm including a couple of photos just to give you a general idea of my setup - also to try & show a very general indication of the illumination (using a 'HiBrite' type LED, nothing particularly special)

difficult to catch on camera, the LED is actually red but in the photo it appears to have a pinkish colour  - however, the light level is about right for its visibility against the morning sun in the room

i'll leave the setup alone now, and just monitor the supply voltage trend, for a few days continuous operation


i hope you get some quality time on your trip - and plenty of opportunities to enjoy some of the good things we've been blessed with in this world around us!

all the best

Hi All,

Apologies, to conform to Dr Jones Circuit I have moved the Variable Resistor (in my case a Potentiometer) to the negative rail and not on the positive rail.

All the Best.

Prof. Jones,

"without success" -- do you mean it won't light up the LED, or what?

The transistor oscillates and the LED lights up but only when Ro is around 0 Ohm (very bright). The frequency and waveforms seems different than yours. Once i measured around 200KHz (visually in the scope). The frequency changes if i change RB (is that supposed to happen?) The circuit is very unstable.

I must buy some 2N2222, red leds and built an inductance meter to confirm the coil.

When you have a couple hours free, a thing you could do to help people replicate exactly your circuit is to create a "replication for dummies" video or document! Starting with an empty bread board and components and gradually mount them and measure the waveforms and do all kinds of checking. This seems to be a difficult circuit to replicate, the smallest detail probably changes the way it works.

Regards,
Jaime

I note that 5 or more entire pages have gone by in this thread and only a single person has said anything about measuring ENERGY in and out in your circuit.... besides me, that is.

TK,

I don't think anyone would disagree with your valid comments. The importance of measuring energy levels rather than power has been well driven home in the past, especially by Bedini. However, comparitive average power measurements are good enough IMO to show whether this circuit is working close to unity and as I see it, this is what people are doing in the first instance to 'get a feel for it'. I see no point in going further unless there is a clear indication of super efficiency. I'm now happy from my replication that this circuit is nowhere near unity, so will not be continuing. I do hope that others can satisfy you with their measuring techniques and validate Steven's claim of overunity with their replications.

Hi All,
I have some more results. I have rebuilt the circuit quite a few times and am getting good results on the measurements so far. I have improved my output readings so far as to say I believe I have replicated Dr Jones Circuit and results.

I have used a JFet, model J6910, from Fairchild. Its a salvage from an old TV. Any way, please point out any mistakes you can see and I will be happy to correct and remeasure. My Probe on voltage is set to DC. My Probe on Sense Resistor Current is set to AC and this is the same for both input and output measurements.



All the Best.
