Hi all,
I started out my HHO project by building a 4-plate wet cell in a container with tap water and soda. That worked however the water became brown and green and I didn't install that in my car.
This time around, I made a proper 7-cell dry cell in +NNNNNN- configuration. Plates were made out of titanium, and covers are made from 1/2" acrylic glass, cell gap - 3mm, surface area of the cells (excluding gaskets) - approx. 27 sq. in. (5" * 5.5", subtract one corner for electrical contacts). I've got a very small leak of about 1 drop of water per half an hour which i think will be fixed by tightening the bolts by 1 or 2 mm. Plates were cleaned with Clorox bleach household cleaner to remove grease/dust/marks/etc.
The problem is this: it doesn't produce any gas. I used distilled water and baking soda (I know it's not ideal but it should work) and get no production at all. However, wires touching the plates produce sparks so there is a current. I'm going to buy an amp meter to measure the current and place an order for KOH to get rid of the soda, but in the mean time, could anyone tell what else I can do to start production?
Also, when disassembling the unit after the first failed attempt, I noticed that couple of plates became brown. That could've happened due to me trying to connect one of the wires to a neutral cell (basically, making it a +NNN- setup) in a bid to increase the voltage - at one point I connected the wires to 2 adjacent plates - could that have made the plates brown? For the record - increasing the voltage didn't start production.
I tried putting 2 plates connected straight to car battery (12V) into a bucket of tap water with soda and the reaction started immediately - I saw bubbles forming on the plates (acting on a suggestion from a friend to test if titanium is a good conductor).
Thanks.
