@jmmac, @gyulasun,

My understanding of Russian is limited, self-taught.
jmmac, you are correct in understanding the video. The experiment has it's own thread. It starts somewhere here: http://www.001-lab.com/001lab/index.php?topic=1056.2800  , unfortunately it is in Russian. You will notice there that the schematic was updated with the capacitor in parallel with the collector coil. This tunes the ringing of the oscillator to the natural frequency of the ferrite. Somewhere in the thread he, Tiger2007, explains how to identify this natural frequency: a coil is wound on the ferrite and driven with the square-wave, the ringing occurring during the transitions of the waveform is at the natural frequency of the ferrite.

Best regards,

yfree

Hi yfree,

Thanks and unfortunately my Russian is rather rusty and miserable so if sometimes I catch one or two words it is a success... 

It is interesting that Tiger2007 tunes the coil hence the oscillator to the natural frequency of the ferrite and I assume when he shows the blown-up scope shot in the video on the ringing he just mentiones that. Maybe a magnetostrictive movement of the core material is achieved here (like in transducer used in an ultrasonic cleaner, not in a piezo but in a magnetic type) and this might give some extra juice. If this is so and this process is involved in the extended running time, then maybe it is worth experimenting with it further on. It would be good to read Tiger2007's findings on this circuit with respect to the longest runtime.

Here is some more info about this: http://freeenergylt.narod2.ru/vladimir_pantiuhov/

Thanks for this link too and if you happen to figure out info on the runtime, please mention it here.

  I'm back from the trip to California where I spoke to colleagues.  A brief summary of where we stand on the blocking oscillator OU? device seems in order.

1.  After months of development and learning, the initial device was tested by me using a Tektronix 3032 scope to measure  I(t) as voltage drop across a 1-ohm resistor and V(t) and the instantaneous Power was displayed as the product:  P(t) = V(t) * I(t).  Then the Tek3032 was used to calculate the MEAN power from this waveform, over numerous cycles.  Finally, I calculated n = Poutput / Pinput and found n ~ 8 for this circuit, by this method.
My early measurements involved hand-integration of the energy of the power waveforms for Pin and Pout, P(t) = V(t) * I(t), for one cycle, and these integrations yielding Ein and Eout also showed n>1 (back in the Feb-March 2011 time frame).

2.  The same procedure using the Tek3032 was followed for an "exact-as-possible" replication of the circuit by Les Kraut, which showed again n ~ 8.  At this point, I noted that we had "evidence for" (NOT "proof of") OU and shared the straightforward circuit design publicly, inviting any who wanted to test/develop the circuit to do so.  It was the success of the replication and pushing by Sterling Allan that induced me to release the development publicly -- to those willing to build and test the device.  I am a strong supporter of open source development of alternate-energy devices.

3.  In both cases, mine and Les', the input power was tuned (using especially the variable resistors in the circuit) to be close to zero.

4.  The low value of the input power  was checked using the input-capacitor + stop-watch method, Ein = 1/2 CV**2 and Pin = Ein /time, and the values came out:  0.23 mW for my initial circuit and 1.1 mW for Les Kraut's replication, with the output LED dimly but visibly lit in both cases.

5.  I urged replicators to assure that the Pinput was in this low range with the output LED lit, as a first test of whether the replication was in the same ballpark as our DUT's.

6.  Chris built a replication then several versions, measuring n>1 but by a different method which was challenged...  Chris found that sometimes the circuit would stop producing n>1 (by his measurement), and he worked on the stability of the circuit.  He is attempting to build a self-running version as am I.

7.  A few others built or are building replications, but again the power-measurement is a difficult issue, especially for the output power. 

8.  We discussed various power or energy measurement methods to check/complement the math-mean method using an advanced scope to evaluate power, including use of capacitors and use of a calorimeter.  But the self-running system would be the most compelling (in my opinion and that of others).

9.   It was noted that Russian work shows an apparently similar long-running blocking-oscillator circuit, again all solid state, but the Russian is hard to read and how long it runs is not yet understood.

Thanks for this link too and if you happen to figure out info on the runtime, please mention it here.

Agreed -- again the link to the Russian blocking oscillator is here:  http://freeenergylt.narod2.ru/vladimir_pantiuhov/   I have been to Russia for conferences on fusion energy a couple of times, but I do not read enough Russian to be of help in understanding Pantiuhov's work.  If someone could post the "best" schematic from this Russian research, it would be appreciated.

10.  As for myself, I'm planning to work on the circuit using first the method of capacitor-in and output-capacitors -- in order to better understand energy-flow in this circuit.  Then I will proceed with an effort to build a self-runner.  This may take several days or even weeks -- patience requested.

welcome back Steven, i hope your trip was successful and enjoyable (as much as a several hundred mile road trip allows!)

i too have doubts now, as expressed by some with their own readings, as to the validity of my DVM measurements - even when filtered

in one test where readings suggested a value for n > 1,  i checked by observing the load value just sustained by the o/p cap

my system was able to sustain a load of approx 82K ohms, equivalent to an o/p DC power of approx 18uW, but the filtered i/p DC power (according to DVM) was approx 50uW

however, in another experiment (detailed above) i noted that the DC power equivalent o/p from the LED was approx 80uW, which approached that of the measured DC power i/p from an external cell - whilst in addition to the LED o/p it appeared that the o/p feedback was also contributing a similar level of mutual input to the oscillator

further investigation definitely needed!


i am presently testing another variation to see if it's possible for the system to feedback any excess charge into its own supply, using a diode in place of the LED

this new setup also adds an extra transistor to connect the battery only when the o/p oscillation stops

the o/p is fed back both to the oscillator (with buffer capacitor), so that it can sustain a certain amount of operation from an intermittent connection to the cell, and also to the cell

in practice, the operation is such that around 6 short bursts of oscillation occur per second, each burst lasting approx 400us

the cell voltage is certainly rising, but this kind of test is notorious for producing 'false positives' due to cell 'recovery' after previous loading, so it will be necessary to give this particular test a good long run to establish if it can continue to sustain or increase cell voltage

i'll report back as appropriate


good luck with your ongoing investigations, Steven, Chris & any other replicators

thanks

Very interesting approach, np. 
I really like this community of EXPERIMENTERS.  That's the way to get answers, by experiments.  You guys have jumped in and made the measurements, and reported results and its so refreshing!   

I also wish success to ongoing investigations, including the Muller/Romero and other approaches.  The solid state approach under discussion here has advantages of ease of build and testing, and I'm learning a lot from this experiment.

Thanks again,
Steven
