Hey all,
It's been a while since I posted. I've been mostly lurking, reading up on Painless' experiments and learning from other people's trials and triumphs. That being said, I think I've stumbled upon something that may or may not be important. Or I'm just being paranoid. Also, I haven't seen this mentioned anywhere else.
Ok, so, we're all in agreement that the amount of wattage to put into your system (for most efficiency) is directly relative to the total active surface area (4:1 ratio), correct?
Keeping that in mind, I used that to calculate the total wattage I should be pumping into my dry cell (once it's built) to be at approximately 261.324 Watts. My design has a total active surface area for the entire dry cell is approximately 1045.296 square inches.
I have a total of 25 plates. Two sides per plate is 50, subtract 2 to get a total of 48 active sides (since those two sides from the end plates wont be used for HHO generation). My total active surface area per side of each plate is 21.777 square inches (1045.296 / 48). This is after taking into account the amount of holes (two 1/4" holes at the bottom for electrolyte flow). Keep that number in mind.
So, for bench testing, I have a 12v power supply (yes, I used a PC power supply). It can handle a total of 35 amps on the main 12v line, but that is not important. What IS important is how many amps I need to use to get 261.324 W with 12v. Let's do the math:
261.324 / 12 = 21.777
Cool, so in order to get my target wattage, I need to pump in...hey...waitaminute! 21.777 is EXACTLY the active surface area for one side of a plate! CRAZY!
Has anybody else noticed this? Like I said, I haven't seen it mentioned before (and I've been reading these forums everyday for the last few months). Try it out yourselves. I want to know what I've stumbled upon. Am I crazy?
