and lithium everywhere.  The burning lithium will not be able to put out
with water...

Hey cool, explosions!

Ja, what I meant was submerge the batteries for about an hour, then take
them out of the water.  I don't know how those things are packaged but I was
not aware the individual cells are impermeable.  I thought they had jillions
of 18650s which were exposed to air for cooling but inside a case which
itself isn't water tight.  Does anyone here know from Tesla batteries?
Guess I could research it, no worries.

Another possibility, just instrument some charged bare 18650s.  Then soak
them, see what they do over a coupla months.  The best we could get is a
small boom outta those.

Stuart here's where I am going with this experiment.  I went thru a
hurricane in Florida when I was age 5.  The streets flooded but most of the
houses didn't.  Ours didn't.  Our neighbors in back did.  What I remember is
when the water was the highest, some people had cars in their driveways.
The water partially submerged some cars, typically the back ends, but that
didn't wreck the cars.  You could replace the carpet and in most cases they
were still OK, but they would rust quickly if they had been partially
submerged.

When Hurricane Katrina hit LA in 2005, a lotta cars were completely
submerged.  It became profitable to find new salvageable cars, hire a bunch
of proles to replace the upholstery and seats, flush out the engine, detail
it carefully, then haul it to California where we don't really have floods
and sell it to some unsuspecting used car buyer with an investment of a few
thousand bucks labor.  High end cars were profitably salvageable, but
submerged cars tend to be problem children forever, because of hidden
corrosion.

OK what about a Tesla which has been partially submerged?  Now these Tesla
drivers cannot trust these cars to put the explosive bahstids in their
garages.  So... they haul them to California, where Telsas are popular,
charging stations are common, the air is dry so they seldom burst into
flames, unless... they were temporarily submerged in seawater during
Hurricane Ian?

What if they were?  Is a Telsa battery submerged for an hour in seawater
more likely to explode eventually?  Anyone here in the market for a used
Telsa?  Do you feel lucky?
