Reviewing the Bedini Circuit

I have an observation I would like to hear from others on.
I have been rereading the Bedini Beginners Handbook
It appears that the rotating magnets are not really needed in order to create the large voltage spikes, ie the "Radiant Energy" that occur from the collapsing magnetic field of the electromagnet which is powered by the "Run" battery, especially higher voltage ones. The rotating magnets are only for the Trigger coil.

Is this actually true?

The reason this is so important is because if the higher amount of radiant energy which Tesla talked about is to be achieved, then the frequency of the cycle has to be in the megahertz to nanohertz range (I think l I read this from The Free Energy Secrets of Cold Electricity, but I'm not sure) with a narrow "On Time," which doesn't seem possible with a simple rotating wheel with magnets attached, or using a Hall Effect sensor, etc. I wouldn't expect these rates to be accomplished without actually utilizing a solid state circuit controlled by a microprocessor, or other dedicated timing chip to generate the timing to the NPN transistor or other such device triggering the magnetic field activation and collapse.

And along these same lines, then it seems reasonable that an air core coil would be more useful because of its working in the higher frequency ranges.

I would appreciate any input from those more knowledgeable, both theoretically and experientially.


thank you,

nanohertz? Hey, why not. Tho it was kilo, mega, giga, tera. But Tesla had no gigahertz. not even megahertz. Back then they had mechanical oscillators that barely reached 20 kHz, just enough to do some archaic radio signals.

As for Bedini, what seems to pull energy from the hidden potential is the spike of the back Emf, that is the collapsing field of the coil. People argue there is no gain in the spike, but actually it is the amount of change in the magnetic field that defines the power output, therefor a short spike has more power potential that a long low dc pulse. For this reason people use interruptors to repeatedly collapse the field in quick series. Seeing this dense "fence" of spikes on the scope shows clearly a huge potential of excess energy.

The length of the Back-Emf depends on the coil. You may also try to let it ring and synch the pulse rate to resonate to the ringing, but it's also effective to simply grab the first spike and don't fiddle with resonance.

The supply pulses need to be perfectly square wave, cut off abruptly. Reed switches can do that, although they get fried soon. Also Sparkgaps and relays. Using Transistors and Fets is possible, but make sure the square wave is perfect and also prevent them from being damaged by the bemf spikes.

Hello TinselKoala and thanks for this. I know I've seen this link before and watched the video. It means more to me now as some things are sinking in and I not only have a little more experience, but have hundreds of pages of theory and watched tons of vids, plus wound some coils, both my air core Star-Challis counterwound, a bifilar with iron core, and my first 8 filar iron core.

I am definitely interested in pursuing the air core, high frequency route like Tesla seemed to be doing. I think with todays electronics this will be an aid.

Then you should be looking at Solid State Tesla Coil designs, and forget about Bedini-style pulse motors.

The very simplest SSTC designs are "Slayer Exciter" or "Kacher" circuits. But you can get a lot more power  and performance if you use Tesla's design principles and modern PLL circuits with full H-bridge driver for the primary.
