Some information....
http://en.wikipedia.org/wiki/Naoh
"Sodium hydroxide does not attack iron or copper, but other metals such as aluminium, zinc and titanium are attacked rapidly."
Saw somewhere a pic of someone soldering copper wire to an ss plate...solder was then covered with something like Goop?
They do make ss pop rivets. Copper ring connx riveted to an ss plate?

http://en.wikipedia.org/wiki/Solder
"Hard solder
As used for brazing, is generally a copper/zinc or
copper/silver alloy, and melts at higher temperatures."
I was also wondering as to how much current was wasted getting to the functioning part of the ss plate.
I want better mpg....
