PhysicsProf Steven E. Jones circuit shows 8x overunity ?

@albertouno:
   
  As I follow various approaches/ attempts at OU, I'm finding that measuring Pout and Pin (to evaluate Pout/Pin = efficiency n)  accurately is difficult -- particularly measuring Pout.   

A few months back, on this thread, I recommended use of a capacitor and time measurement to evaluate Pinput -- still a solid method. 
Measuriing Pout has proven difficult here.  Like you, I tried charging a capacitor on the output leg -- but there is a problem (discussed in detail earlier and in nul-pts notes).  If you discharge a chap into another cap B (at 0 volts initially), you find that charge is conserved but ENERGY IS LOST -- to sparking, resistance etc.  Follows from basic physics and you can retrace on this thread if you wish.

SO -- I am currently using two batteries in series for the input, and two batteries (all rechargeable) in parallel for the output.   This may provide a solid test -- results noted in my post earlier:

[with] my revised circuit along and I'm getting some interesting results.  Just to mention one -- the supply batteries (2 AA rechargeables in series) maintain a constant 2.50 Volts (may vary in the mV range, but not measurable on my little DMM) while running an LED red, brightly -- and charging 2 AA rechargeables in parallel...  for over 24 hours.

  Note that I've removed the CSResistors.  Lo and Lb are 354 and 355 uH respectively, R is 51Kohms, Q is 2n2222.    Bifilar-wound toroid described in the first few posts of this thread.   

Before posting numbers on the recharge voltage rise, I want to repeat the experiment - this time with a control.

Gotta run -- on the road again.

Now I'm back and will be posting results -- whatever they turn out to be -- in the next several days.
Right now, I'm establishing a baseline for battery voltages... Batteries need to "sit" for some time to reach stable voltages.   Clearly we need to measure to the mV scale which I do easily with the older Keithley in my home lab.

The circuit I'm using is repeated below -- VERY simple, really. 
Can you duplicate this circuit, alberto?  If so, pls do.

I'm following the Thanes' transformer also...  I don't know if there is "real" OU here or not, but replications claiming OU are there (but few).  Would like to try a build, in parallel with my work on this blocking-oscillator circuit (attached).

Thanks for the response, glad you are back.  I will try testing your suggested circuit, but will be heading to Hawaii for a 2 wk vacation soon, so would like to finish before then.   I have  charged batteries before with the Bedini circuit.  I believe some batteries may have an equivalent circuit which includes a large capacitor (farads).  Noticed this when plotting the discharge curve of a battery to estimate the energy collected.  (like an exponential RC decay).  Not sure if this will complicate the test.

Have a great vacation, alberto.
Can you explain how your plotted "the discharge curve of a battery to estimate the energy collected"? == I'm interested.

(I can imagine draining a battery into a large cap and using E = 1/2 C V**2, except it may be difficult to calculate the loss of energy due to "leakage" from the cap...)

Here is your overunity: http://www.w8ji.com/vswr_reactive_power.htm
Apply reactive power to real power lenzless transformer like Thane kind or others.

hi Steven

welcome back!  i hope you had a productive trip and an enjoyable time with family & friends

can i add some battery charge test info, too?

when i was pulse charging NiMHs & NiCds with my switched-charge capacitor circuit a couple years back, i would 'characterise' the cells/batteries first: ie.

- give the cell(s)/battery under test a full charge from my commercial charger;
- then discharge them through a known resistive load (say approx C20 discharge) down to about 75% nominal voltage, datalogging the terminal voltage every few minutes;
- then import the data into Excel and get the total energy from  instantaneous power & time calcs.

then i would charge the test cells/battery with my circuit and repeat the data logging exercise

for comparison, choose a representative 'start' & 'end' voltage as the limits for the energy 'integration' calc

see example graph posted below

anyway, that's just one method - over to you Albertouno

thanks
