Hubbard coil

[innovation_station]

Heydude, the diagram attached is the source of this speculation (which is what that was). I was trying imagine the method of stimulation Hubbard used.

IF (big if) it was an eight cylinder distributor, which normally distributes a (35 to 50kv dc) spark working from the center plug  to the 8 spark plug wire terminals around the circumference of the cap (by way of the rotor inside), then one could maybe imagine that he wired the eight plug wires common to the high voltage source and shot the spark out the center plug wire, giving him 8 sparks per distributor shaft rotation.

The claim is that there are only 4 wires to his coil setup. Two wires were presumably for the load, and two were for the stimulation and maybe feedback for the 8 coils. This one wire from the center plug wire of the distributor could have been connected to one of the 8 coils wires, with the other 8 coil wire returning to the high voltage supply return.

Hubbard had mentioned that his coil builders couldn't energize the coils, only he could.

So it seems to me that he probably delivered a constant high voltage (11.25 Kv), as very fast pulses, which he varied the timing of, by controlling the speed of the distributor shaft.

I could be totally out to lunch on this. I was seeing the variac as a potential speed control device for the motor spinning the distributor shaft.

It's also possible that the distributor rotor may have been modified to change the spark's duration or strength.

I apologize if I have misled anyone! I have no idea at all on how Hubbard did what he did. It just seems that it might be a Tesla-esque method: hit the coils with high voltage pulses at a speed that promotes self resonance (maybe)?

that may well be the case..... 

ist 

i bet 2 wires are to start it and   then become antennas.....

Epiphany

Thanks for your explanation. I first saw that photo you posted (Hubbard2.gif) in a book of  attempted free energy devices back in the mid to late 80's. As I recall, it was an attempted replication based on someones idea of how it might be done, not an actual Hubbard device.

Some of the meters and other parts are modern types and not available in Hubbards time period.

I will try to determine who the builders were if I can locate the book.

Thanks again

The center coil could also be in series, between the ignition coil and the distributor, causing a pair to be fired, the center one and one of the eight in a circular sequence.

All of the articles I read mentioned only 4 wires exposed though. I can't see how a single coil out of eight could be selected to fire with the center coil. Not saying that it couldn't be redesigned of course, but just staying with the original story...

IMHO exactly the same principle was used in Tesla device powering his Pierce Arrow model car.
