Are Tommey Reed´s pulse motor circuits overunity ?

Makes it harder now as in the realms of kitchen table builder where OU becomes smaller and smaller value. This is where bedini builders slip into non OU or barely OU and measurement errors are easy to debunk. Now with just 50 milliwatts spare OU builders see special battery conditioning and other excuses.

The pulsing of the Bedini coil is exactly the same so if you make a huge one very well built with 10 coils then OU becomes clearer as system losses get smaller versus OU gains.

So is this going to settle down to duty cycle factor mistakenly used twice in efficiency math?

Yes, I also mixed that up until Groundloop brought it up,so my former efficiency calculations were wrong.

The input current is already the AVERAGED CURRENT due to the duty cycle averaged into it !

So you really have to take the normal input voltage and multiply it with this averaged input
current of the meter to get the input power.

You can not calculate again the duty cycle into the input voltage, that would give wrong results !

I made this error myself at the beginning, so these OU statements were wrong.

I wonder, how his digital clampmeter measures the duty cycled input current pulses.

Can it really show an averaged input current via the right internal integration
or will it get jammed by the pulses ?

So for sure a
1. graphical measurement ofthe input current with shunts and scope shots
or
2. a lowpassfilter DC like input current measurement directly
at the battery before the lowpassfilter

would give much more accurate input current readings.

I really don´t trust his digital clampmeter being able to show the real
averaged input current , which is needed to calculate the correct
input power.

I think Tommy should just measure the input current with an old fashioned analog needle meter and that will show the current quite accurately. The output (motor) current is  capacitive DC current and those meters are probably OK. I sent Bolt's remarks to Tom. He has yet to respond.

Here in this video:

he has a COP of about 1.3

Output:
24Volts x 0.068 Amps= 1.632 Watts

Input:
12 Volts x 0.105 Amps= 1.26Watts

COP= 1.3

Here we have about 30 % overunity.

P.S. To calculate the duty cycle into the battery voltage is wrong, cause the measured input current has already the duty cycle averaged in.
