Shorting coil gives back more power

[Feynman]

Hey guys, check out this thread, there might be a breakthrough with Thane Heins' device.  David has done his own toroidal replication which appears to be COP=8

P.S.  I started a new thread.

The Gabriel Device, possible COP=8

Does anybody have good and reliable circuit to dump cap at preset voltage to battery (at 100v dump cap to 36v battery bank)  ?

Hi joefr,

There is a patent application on just such a circuit you need, it is US20070222411 by Jean-Michel Cour.
(go here http://www.pat2pdf.org/ and copy and paste 20070222411 to freely download this patent).
The application text describes how the circuit works and includes component values too.  You can adjust the voltage divider resistors to choose the range for the comparator to fire a FET switch for discharging the capacitor as you need.

PS Would you tell what way you create the sine wave in your coil?
    And what happens to the sine wave when you short it out? Why does it flatten out between the spikes?

Hi Gyula

Thanks for patent

Would you tell what way you create the sine wave in your coil?
For creating sine wave I use this big bicycle wheel from my other previous project.
I connected your circuit to generator coil and to FWBR, then I charge a cap 680uF 200V and for now manualy dumping cap to battery when it reaches 100V.

And what happens to the sine wave when you short it out? Why does it flatten out between the spikes?
I got 2 day ago my first oscilloscope and I am not yet familiar with all the settings 
I will take more photos with different setting and see if I can find the shorted sine wave.

Hi joefr,

Very nicely built setup you have! 

Maybe it is not the scope settings but the ON time of the shorting switch?
First try to short only ,say, the positive peaks of the sinewave, for about 1-2 millisec duration. (In your scope shot you have nearly 10 millisec time for one full sinewave, and you wish to position the Hall sensor so that it would be ON for 1-2 msec at just at the positive peaks).

Later your manual damping of tha capacitor could be done by the circuit shown in the patent application (Unfortunately, Jean-Michel Cour died about 3 years ago, he was a very good engineer and experimenter.)

Hi Gyula and all others

I manage to record a short video of coil shorting. I tried many things but I always get flatten sine wave between the spikes.

I will make a new more powerful generator to take advantage of coil shorting.
I will design it in SketchUP and send the design to machine shop to do the laser cutting all the parts.
I am thinking a similar design as watson generator with heavy flywheel.
I will be using 8 coils but I need proposal what will be better to use 7 magnet or 9 magnets?

And what diameter size of bottom magnets would be fine for good power generation with coil shorting (charging caps and then dump to battery ):

I am open to suggestions and ideas before I start designing in SketchUP
