You can tell a PhD in Engineering today from the soldering iron burns on
his hands -- they don't know which end gets hot.

Then they need to get those new "cool" soldering irons, they advertise on TV
all of the time.

I can't imagine how those would work worth a damn. What do they have in
them? My guess is a small, low mass filament, almost like a light bulb. I
would imagine that if the thing you were trying to solder was of any size
(mass), they would not make enough watts of heat to get it up to
temperature, within any reasonable time.

Anyone have one, or seen one in action?

Two electrodes. (You can't get much simpler than that) You short them
together with what every you want to melt. That's assuming what ever
it is melts at less than the electrodes and the really wild assumption
that it'd have enough power to do so. :-))
