what did you clean the plates with when you first started the vspb block and did you sand them at all?

Just a suggestion for the braces, use a pair of triangular pieces of plastic on the edges of the bottom braces to form an A bracket.

Great video ZeroFossilFuel!! I just know that plates edge will cause current leak!!
LOL!!
Thank for the information!!

Thank you for the details. I built my first cell out of enthusiasm, with fender washers, lock washers and 3 1/2 inch 5/16 bolt... and was not pleased with the results. Your style of design with neg.plates will be my next project. Keep posting-we will catch up soon. Denver395

EasyTBear is right, you need efficiency, not volume. If you are producing 1 LPM at 40 amps, you will be use lots of power to make 40 amps. I use 10 to 15 amps to produce 1 LPM. Multi cells run in series work the best to lower heat. Many cells are to complicated, make multi cell units with 2 to 3 volts per cell.
I like using baking soda, because it is not dangerous. Caustic soda is a much better electrolyte, much less is required and it doesn't gunk up your cells like baking soda.

I have an unfinshed design using an inverted
4" PVC wye. 2 3/4" x 7 1/4" plates, 12 or 14 cells divided into two groups wired in parallel. Neutral plates, edges sealed, etc. I have a construction issue with the electrodes having to be through the sides of the tube which lends itself to leaks. I may have to go to closer spacing and back to a straight tube like you did.

ETB - You clearly have a firm grasp on the HHO game. Have you built anything yet that you can show off here?
EasyTBear (November 30, 1999 at 12:00 am)
Use neutral plates and 1/4 - 1/2 amp per square inch current density (I calculated you are using 1.43 amps per square inch at 40 amps with the plate size you stated.) Also do something to limit current leakage such like what ZeroFossilFuel does or use shrink tubing. You are limited by the available power and size of generator you can install. You are producing a lot of steam.

EasyTBear, can you be more specific? I am running my unit with a 12V source ans 100x90mm plates. Playing about with no. of cells and also the gap. I want to get as much gas as possible to aid combustion so whilst efficiency is importany I need the gas!! How do you control heat to prevent the current?? I was pulling almoat 40A from my last cell but production was only approx 1LPM. Any comments would be gratefully received.
EasyTBear (November 30, 1999 at 12:00 am)
Design your unit to use the power available. The number of cells based on the voltage. The plate size based on current density. Then you have to control heat to prevent current runaway. Efficiency is more important than gross hydroxy production. |
