Hey Gyula

Try this code in the sim prog from Falstad.com   I know you have the sim but in case anyone else does not know of it.

It is the circuit I descibed above with the addition of another diode across the source to continue the loop after the source is disconnected. The diode does nothing until the source is cut off. Then it allows the coil to pump the caps charge from one side to the other as it winds down from the flywheel spin. 


Run the sim. The scope on the left is the source voltage and the one on the right is the cap voltage.
Hold the switch until the cap reaches 20v or so, then release and watch. When the switch is closed, the diode next to the source is inactive till the source is cut.   

I am going to put together a comparator circuit to compare the source and cap voltage to operate the switch when they are equal.  Even if we cut the switch when the cap is around or below the source voltage, the cap will still contain more energy than what came from the source.  I challenge anyone to test this theory.  TK ?  ;)

Hey Gyula
I would say that all of this is ON topic and it is to the point on the hows and whys of emf and bemf.
Everyone here should pay close attn to this info. Its truth and directly related to the actions of the coil.

When I was in electronics, I remember it just as close as Chris described. But it is not that way at all. I just didnt have a free energy thought about it back then.  They did tell us that the bemf energy wasnt worth saving and to kill it with the diode, in cases where the coils currents were being interupted.

Mags,
Over here post # 24 from allcanadian
http://www.overunityresearch.com/index.php?topic=261.msg6042;topicseen#msg6042

Interesting excerpt

" Now if as many believe, the input must be equal to the output then why do I get two equal outputs from only one input?"

------------------
Sounds like what you are saying?
 Their Trying to get a schem.
