Hi Joe,
Postive results from the mixing of water and electricity can be found in
primitive desalinization techniques, and also as a means of generating
small quantities of hydrogen for laboratory use. Level detection in
water-containing vessels is another one as is the indirect heating of
water (as in an electric tea kettle).
Regards, Art Michael
