Regarding The Ed Gray Motor

cool cant wait to see the video. awesome news. well done

Sounds great, Beshires!

Just one question at this point: do you have a diode between the coil and your CSET?

No, but I have the high voltage running thru a 400V 50 amp bridge rectifier. I have been thinking about running thru a rectifing diode as well, just haven't hooked one up yet. Here is a picture of the tube.

Right now I have it set-up with the high voltage (on right) going thru the carbon resistor, then to the low voltage electrode on the left. You can see the diode that allows the low voltage potential in to the tube. Set up this way all sparks that jump to the grid are off the low voltage electrode. I'm just trying it out this way.

Here is a video of the tube in action. Sorry again about the darkness, my camera seems to film things differently than they really are. I am actually in a brightly lit room.

great video thanks

[nat1971a]

the spark looks blue in the video or is that just the video....is it still yellow?

[Beshires1]

Yea its blue. I've tried all day to get the flaming effect back but to no avail. Here is a interesting bit. When I first turned it on this morning, it sorta poofed a very large blue flash, the instant I threw the switch on. Poof like a camera flash. But only that one time. Weird huh? I think it could have been a small amount of glue fumes may have collected inside over night. Anyway That could have been the cause of the yellowish sparks I got yesterday.

[Beshires1]

Can anyone tell me, if they are for sure that they are getting a capacitor discharge through the Ed Grey Tube? Not just shooting high voltage from a ignition coil through the tube but a actual thumping discharge? I am using a disposable camera capacitor, Hooking it up like the Grey diagram shows and I'm getting nothing. Sometimes when I tinker with the circuit The capacitor gets charged up but doesn't discharge.

[Beshires1]

I think the capacitors were discharged by the commutator, and I think he used a lot of them. Look at this drawing from his patent. I think with using the circuit only we can't get the results we want because the CSET Schematic is only half of the deck.

Commutator Arcing

I recently did a test with a small motor connected to my grid through an ignition coil. The coil was wired in reverse, with the HV side going to the grid. This was to see if stepping the voltage down would produce enough amps to turn the motor without a battery.

There wasn't any turning of the motor, but I did see some sparking at the commutator. I've since realized that the commutator segments were too close together, and were providing a short circuit pathway for the voltage.

The total arc gap length around the commutator, between the segments, might be a factor in what type of motor can be powered by a CSET. Unless this arcing doesn't conduct the low voltage when a battery is also used. Otherwise, a motor with a large diameter commutator might be needed, for the voltage levels we're testing.

[nat1971a]

i have been trialling various capacitors in series and it does change the spark in my system in various ways so i am assuming it is discharging as per the circuit. But i havent really been checking it that thoroughly.

having said that i just ordered a 2uf 3000volt cap to test out as well

[Beshires1]

Here is the deal I think I know what the reason for the lubriplate in the commutator was for. Watch this video, this sparking connection has to take place inside of the tube for the capacitor to discharge thru the coils.
Capacitor Discharge Popping Coil

[Electrotek]

This is an impressive demonstration. Have you tried hooking it up to your little motor? What will happen if you increase the voltage?

[Electrotek]

Beshires1: I think you're right about the CSET being used as a switch. Otherwise, the spark gaps errode too quickly. And an Ignitron could be used as the switch, similar to Gray's coil popping circuit. But don't expect to get any Over Unity from that tube. That circuit had a reported efficiency of 4.7%.

If I hooked the small test motor up Like I have the "popping Coil". It would, spin like hell, then probably burn up. This is 26 volts rectified DC from my 140V variac. As for the "popping coil", I gave It a 50V capacitor shot this morning, It pop like a firecracker, and the flash was near blinding. I think I might video another large shot later tonight. The thing is I can disconnect the power and using only the cap and discharge threw the coils. With my ignition coil, I cannot get a capacitor to charge at all. At least not with power that will magnetize the coils. I dont think Grey did either. After finding the description in the patent to this: http://www.energeticforum.com/attach...commutator.jpg
I think he used a large DC capacitor for each coil, pulsing the rotor coils and stator coils with a large capacitor discharge from his battery packs. Also I thing the Tube was high voltage, enough to charge another set of batteries. And the overvoltage device 42 may have been to dissipate the large DC blast from the capacitors, that is, what wasn't pumped back into the tube via the grid connection.
Just some of my thoughts.
