Shorting generator-coils

[nilrehob]

This is so interesting i figure it needs a thread of its own!

By shorting a generator-coil you get nice spikes that can be captured (or just light a neon-bulb as below).
This is also reported in another thread:
http://www.energeticforum.com/renewa...ow-motion.html

Its the third circuit in this picture:


I really think there is a great gain in this.
The coil can be shorted at least two times per passing magnet.

If anyone has a generator-setup where this can be tested and compared to when not shorting the coil,
i would be very interested in hearing the results of the comparison.

I will try and find movies I made about 2 or 3 years ago. Basically it was a permanent magnets generator and I was using MOSFETs and function generator signal source triggered by opto-reflective switch to get about 2000 cycles when one magnet would pass the coil. I didn't see any gain in that- just additional losses in MOSFETs.

However I think I still have those movies somewhere. If I find them I will send them to you if you think that would help you.

The output of the spikes depend alot on the voltage of the battery you are trying to charge with the system. If the battery voltage is below the peak output from the generator then the coil will have drag on it. if the voltage is above the output of the generator in standard mode. the only drags on th system is what is inherent in the generator ie coils attraction/ friction and the brief period while the coil is shorted. In the same thought if the generator can put any current to the battery without the monentary short then the voltage of the spike will be lower because the magnetic field created by the flow of current could not fully collapse. Air coils are good generators to test the theories since they already eliminate coil attraction of the magnets.

Does anyone know *exactly* when it is that the spike occurs? Does it happen just as the reed switch closes (make), or when it re-opens (break)? I suspect the latter, but I have no way to test for sure.

[lighty]

Voltage "spike" occurs when switch opens.

Spark

Do you know if your reed switch is sparking when it opens?

I posted this info in another thread but it got dropped so ill put it back up again. A few observations i made while experimenting with this are the following:
The coil behaves exactly like pulsing a bedini coil, you need to adjust pulse duration to hit the resonant impedance points in the coil. When you do this, you get more output and less drag on the prime mover. You can also use a variable capacitor in series with the short to hit the sweet spot. Or just adjust your rotor speed. You will need something to turn your generator wheel at a constant speed to play with these variables and notice the effects, and it may be hard to adjust pulse duration with reed switches, but you could do it with 2 of them.

In EVGRAY group, there have been a extensive talking about this procedure at obtaining serious power.

user KoneHeadx, has bult and suggests the building of such machine. He has not clarify if it is OU, but he says a lot of gain.

He has been answered many questions of mine and suggests that the best way to harvest the resulting spike from passive generating coils is as following:

At the peak of voltage build-up on the coil (unshorted) there is a shorting circuit usind SPDT switches. The short is very brief, otherwise if considerable currrent runs LENZ drag kicks in.

The sensing of the voltage peak could be achieved by stationary ways, as a reed switch or a neon sensing circuit via a voltage divider. The latter aproach offer lots of advantages since rotors with speed tend to alter the voltage peak possition due to magnetic field distortion effect (see wikipedia), unless adjustable reed switch is applied, but again its difficult to say how the short should endure.

....
KoneHeadx, supports that caps could be charged this way, and by suitable uf value of caps voltage stored via a single pulse could be x20 than coils voltage.

concluding i have not built this kind of device and is on my do-to-it list.

Yes, that would be interesting.
Do you have the schematics too?

I have not seen any sparks on the reed-switch.

You're right, there is a lot to experiment with this simple circuit.

This is exactly where i got it from, KoneHeadx is very kind and informative.

I would have to look it up but it's rather simple so I guess I can draw it for you again. It does use reflective opto-switch and MOSFET drivers though. They are not hard to get on Digikey (if you're from the US) or from Farnell (if you're in Europe).
