Ok Hydro, I've been thinking, and this is what I'm going to try next chance I get, and I'm also posting it here hoping someone else with a similar set up will try it too. (probably mid week I will get a chance)
Procedure:
1. Fill cell right to the top with water.
2. Siphon out 500 mL of water to create 500 mL cavity.
3. Start Cell, record psi after 1 minute. If cell maxes at 5 psi before 1 minute, then try 30 seconds...
4. Release gas pressure into inverted bottle full of water, let it rise up to release pressure, measure expanded volume now that psi is at 0.
This will provide a relationship between psi/min and cc/min. However we would not be considering the fact that hydrogen gas is less dense at atmospheric pressure, therefore in this test we will have some error that may or may not be significant, but it should still give a result that we can compare directly with Stan's result.
Stan says 7000 cc/min, my cell is 7% the size of his, assuming gas production is directly proportional to cell size, I might expect 490 cc/min.
I will perform this test with Rain Water. If I feel like it would be useful, I will repeat it again with Tap Water, Distilled Water, and maybe Well Water, and Salt Water...
