The only conclusion that's incorrect is if you think the current will "choose" one path over the other, as if it were a switch. It will divide among all possible paths, and I'll leave it to you to decide how much and where. Meanwhile, I'll watch, rather than getting into that pool. I must live in a unique town, if the comments (or lack) are any indication. The tap water here in S. California has a legendary amount of minerals dissolved in it, and conducts very well. So would any swimming pool, if they've thrown chemicals into it. I've owned at least two examples of a "vaporizer", sold in the local drugstore for very little money. It's a small water tank made completely o= f plastic, except for the two electrodes sticking down into the water. Attac= h to 110V mains, and wait 30 seconds. The advice is to add a pinch of salt i= f nothing happens after a minute. Using the water here, you will hear the water starting to heat after 10 seconds, no salt needed. The water boils, projecting steam into the air. It's an old-time remedy for congestion. Nowadays they make ones that ultrasonically disperse the water, so I don't know if these still exist. At their cost, I bet they do. Anyway, no significant amounts of O2 or H seem to be generated. There were no warnings to that effect on the box. A swimming pool, being located outdoors is rather ventilated compared to any gas you might generate there. And then they throw chlorine into the pool water which you can smell anyway. I once made a power resistor (DC) using a glass of salt water and two wires. Later, someone told me the reason the water was turning green was that I was generating chlorine! But I seem to have survived, despite doing this in a closed room. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
