Subject: Re: [Homebrew_PCBs] Preventing oxidation of copper outdoors

What I like about this group is I regularly learn something new, or something more about something I knew a little of..

To be fair to Mr. Midgley Jr., at least he did not
use arsenic instead

of lead, which according to his experiments also worked to
eliminate

knocking. ;-)



On a more serious note, you have to look at his inventions
while

keeping in mind what was known at the time. He was one of
those people

that just got the job done, even if the task was
considered

impossible, and no matter how many skills he had to learn in
the

process.



He invented leaded petrol to give the allied war planes an
edge, by

allowing more compression and more power. That was his task,
he

delivered a solution in time for WW2. Don't forget
nobody considered

lead dangerous then.



As for CFCs, he was faced with the task of finding a safer
refrigerant

that wouldn't kill everyone in the house if the freezer
leaked, again

he delivered. Nobody knew about this ozone layer thing back
then.



Read Charles Kettering's memoir and tell me you
wouldn't have loved to

work with the guy. One time, when he got metal splinters in
his eye

from an exploding tank, and the doctor couldn't get them
out, he

successfully dissolved them by bathing his eye in mercury. I
mean who

has an idea like that?



But there must have been a darker side to the man, one
Kettering

didn't touch on. When the workers got ill at the TEL
plant and he held

that stunt press conference, he must have known this was
unsafe. He

sure knew afterwards since he was sick as a dog from the
lead

poisoning, but I don't think he did anything to set the
record

straight.



I've always been suspicious about his accidental death.
A smart man,

getting tangled up in his own ropes like that, not sure if I
buy it.

Perhaps he was just tired of it all.
