Strange how he thinks a negative charge on the water will result from connection to battery positive. From what I know about electronics (I have a degree and have been around it for decades) the battery positive will pull the electrons from the water, leaving it positively charged.
But really I don't care. If it works then that's all that counts.
But its nice to have a good working knowledge of why.
I want to try some charged water soon.
After reading this forum I pulled out my water magnetizer to use it. Unfortunately I didn't have anything but contaminated faucet water to use, so I took the risk. MAN, did I ever regret that! Worst nightmare I've had in probably a year! arghh! Now I need to try it with clean spring water and see how my night goes. wish me luck!
