The "BOYNTONPOT"

I have started using pot (New cell design I am working on)

All suggestions/comments welcome.

I am building a new cell using a 7" diameter x 4" high SS pot as the container.

(BTW 304 SS = 18-8 SS normally found in SS pots and flatware.)

I have collected several additional pots of smaller diameter and I am in the process of cutting 2.5" tall cylinders out of them.

The inner plate will be about 5" Dia x 2.5" high ~ 40 sq in.

It appears that the spacing between cylinders will be about 1/4".

My question is whether 1/4" with a high KOH % is equivalent to a tighter spacing?

Hopefully this pot won't boil!

Should heat become a problem, I have plans on how to cool it.

With 40 sq. in. as the minimum plate area, how many plates/wiring would you suggest for a single brute force cell?

Guesstimate the output using 25 Amp?

It is also possible to use a 2.5" wide strip of 304 and make cylinders of various sizes from it in order to make additional plates with tighter spacings.

I can visualize a method whereby no welding is required to make these cylinders. I would use a plastic spacer/connector to bring and hold the 2 edges together and against the adjacent cylinder.

I need a "pot" connection for at least 2 more.

Its been my experiance that more spacing requires more electrolyte, but not much. A single brute force cell will have a low concetration of electrolyte unless the voltage is very low. My double cell is two cells run in series with both being seperated by a nonconductive spacer. The Cell's config is +NN-NN+. I believe its actually 4 cells with ~3 volts on each one. In one gallon of water I have to use ~4 teaspoons of NaOH to achieve 10 amps. The spacing is 1/16"

Looks kind of large...is it just for the bench or is it battery tray mountable?

I have room for it between the radiator and the front bumper without blocking the air flow to the radiator.

Cooling fins possible.

It is 7 dia x 5 high.

Pot is ground.

I ran it dirty today at 10 amps and 9 volts just for fun and to see bubbles.

I expect to be able to easily pump 30 Amps though it if necessary.

My hope is to find enough pots to enable 1/16 or 1/8 spacing.

I have 40 sq in to play with as the minimum inner tube area.
