My induction coil keeps smoking!
« on: June 23, 2008, 06:31:40 am »
I just finished my 21 tube fuel cell (only 11 tubes installed currently) and it is shorting out when dunked in the tap water resevoir but not shorting when dry on the counter, outside of the tap water tank?

I keep cooking my 100 bifilar wound inductors when i connect them between the D14 circuit and the WFC, however, I can connect the D14 circuit with inductor to a thermal peltier device or a 12V light bulb without any ill effect or overheating (light bulb shows the pulsing effect quite nicely).

If I then remove the D14 circuit and connect an automotive battery DIRECTLY to the WFC's"+" and "-" leads, Electrolysis happens instantly and vigorously, BUT the positive and negative connections from the battery cables touching the WFC leads start turning red hot from short circuiting!

Take the WFC back out of the water, let it dry, and viola....no shorting??? Why is the water shorting it out?

Any suggestions as to what may be wrong?

The tubes look good. The metal plate and metal rods you used to divide and keep them in place needs to be made of a non-conductive material.
Keeping the water insulated helps tube cells limit their losses. $.02

Thanks Carbed,

The stainless rods are not support rods.

The SHORT stainless threaded rod is my positive lug, and the LONG threaded rod, running the length of the cell,  THROUGH the NYLON insulator on the top plate, connected to the bottom plate, is my negative lug. I don't want any holes in the bottom of my cell when it is complete. All hardware will exit through the top....no leak points.

The lower plate is my negative plate and is connected only to the inner tubes. I have a Parker hydraulic hose crimper and crimped 1/4 316 stainless nuts into the ends of my 5/8 ID .065 inner tubes  so they could thread onto the bottom plate.

The O.D. of the outer tube is press fitted into the top stainless plate making the unit very stable and electrically connected at the same time.


The inner/outer tubes are isolated from one another by 8 nylon rivets. 4 at the top and bottom of the inner tube. The outer tube is a tight slip fit over these nylon spacer rivets. (1.52mm)


The inner and outer tubes are completely isolated from one another when on the counter. I could take 120V and touch the the 2 threaded rods and see no grounding

BUT

as soon as it touches water....I get shorting?

Hi,

nice build cell!

do you know ohms law?
The more tubes you have, the lower the overall  resistance. Its is possible that your resistance with too many tubes is too low.
In that case, you have to split connections and you have to use 2 or 3 drivercircuits.

Stan's were 18"

Trying distilled water next.

Good suggestion.
Try destilled and see what it does.
Another thing...
If you still keep this problem, then you better try tube by tube.
See which tube is giving your problems....
I had to do that once.......

Are you using only tap water and what is the spacing between the inner tube and the outer tube? your using 11 sets of  tubes it draw so much power over 30amps the size of your bifilar magnet wire limits current and my get so hot and smoke, use distiller water what stevie1001 and other suggested to you. Nice work…
