I have continued my tests over the MEG and I have not yet succeeded in a

COP greater than 1, it is less than 1, very less than 1. My las t

experiments have showed no overunity with frequency range from 17kHz to

50kHz with a MOV (see my last email), so I have tried with a Neon tube

in this frequency range, and I tried again with MOV at 2,7kHz (because

it was my best output power result last time, and I am now able to

measure simultaneously input signals too)

The MEG radiates powerfull electromagnetic waves, which I can't measure

because I have no device to do so, but I feel these radiations in my

body (on face, arms, etc) because it's very powerfull. This is, in my

sense, the way the missing Output power goes out (because a lot of power

is missing from expected at output!)

I have used 2 oscilloscopes to measure simultaneously input and output

(on one input coil, and one output coil). My experiments lead me to ask

wether to compute power and which one using to compute COP. In effect, I

read electronic litterature, and we have 3 power types:

P apparent power = Power calculated withe the product U(t) and I(t) [

see http://whatis.techtarget.com/definition/0,,sid9_gci213719,00.html%5d

P active power (or real power) = Power dissipated in Joule effect in a

resistor (Watts) [ see

http://whatis.techtarget.com/definition/0,,sid9_gci213720,00.html%5d

P reactive power = Power alternately stored and released by inductors

and/or capacitors [ see

http://whatis.techtarget.com/definition/0,,sid9_gci213721,00.html%5d

I consider the Output Coil as a power source and my dipole power

consumer is Neon+Resistor or MOV+Resistor

In my numeric computations, I compute:

P = (1/T) * Integral of (V(t)*I(t)*dt, from 0 to T) apparent average power

P = (1/T) * Integral of (R * I(t)², from 0 to T) = average active power

throw resistor R (the problem is that this value can't be computed

because I don't know and can't measure MOV resistor value or Neon

resistor value, because it changes with the applied voltage)

And what can I do with apparent power? Sometimes it goes negative, what

does it mean? I have not changed the way I measure currents, so why a

negative powe sometimes? What is the link with the powerfull radiated

electromagnétic waves? All this leads me to a more profond questionning

about power, its meaning and the way we compute power. What do you

consider as a correct power for COP computations? If you can help me

with your advices, i would be very happy.

Thank you in advance for you comments.

Mr Naudin, if you read this email, please help me: how do you manage

measuring sinusoidal phased signals? (with Neon tube experiment, you

have had this and not me). I really try to obtain something with my MEG,

but each time it doesn't work.

(en français: Mr Naudin, pourriez-vous s'il vous plaît aider un

constructeur de MEG qui essaie tant bien que mal de suivre vos traces et

souffre de ne pas être capable de reproduire un tant soit peu vos

résultats concernant les signaux sinusoïdaux en phase dans l'expérience

du tube au Néon (ou des varistances d'ailleurs) avec le MEG 3.1).

Sincerely,

Pascal DI SCALA

------------- Experiment Resume ----------------

Experiment number 1: operating frequency about 18Khz

I have experienced with Neon tube 4W+Resistor 12ohms on each Output

coil, instead of MOV or conditionned resistor (I have not built such a

device resistor) because I wanted to reproduce Naudin's experiment:

http://jnaudin.free.fr/images/meg32io.jpg

It's disappointing, because I have not at all the same signals than

Naudin (and the cause is not the conditionned resistor this time; I have

the same 3.1 MEG than Naudin's one, except for magnets). The operating

frequency is in the rspacified Naudin's range. But my COP is very poor

(problem with power computations used to compute the COP??)

Experiment number 2: operating frequency about 2,7 KHz

I have experienced with a MOV 840V(two MOV 420 serialized in

fact)+Resistor 12 ohms on each Output coil. I have tuned operating

frequency to maximise input current consumption by the MEG driver in the

2kHz to 5,5kHz range.

Disappointing too. COP very little.

I have also tried to link together output coils, and when doing so, I

managed to obtain approximate sinusoidal waves for output voltage (but

not for output current) at all frequencies, and for special

frequencies, approximate sinusoidal waves for output current and

voltage, with MOV loads. But it is not in ohase at all, dephasage is 60°

to 80°

You can see oscillo shots with voltage and current for these special

signals:

If I link output coils reversing one coil the output volatage is not

sinusoidal:
