Interesting comment on the news this morning: sales of sodium
silicate
are up.
Announcer said car dealers use the chemical to 'kill' engines so
they
can never be repaired.
(Must be tied to the $4500 dollar rebates...) So, do you pour it in the
tank? Air cleaner? Why does it work?



Oil sump... The liquid has pretty high lubricity, and is easily pumped
around the lubrication system, until things start to get hot. Then,
sodium silicate in contact with hot metal forms metal silicates and
silicides that effectively glue the parts together. The more it
solidifies, the hotter the motor gets, accelerating the process. The
solidified materials are also hard enough to badly score any parts that
can be moved.

Sodium silicate is the adhesive in "muffler patch" paste and muffler
wrap bandages.

This destruction of a valuable resource just hurts my mind. OK... DON'T
re-sell the gas-guzzlers. But for heaven's sake, part them out! There
are plenty of ongoing applications for those bigger motors where they're
necessary, and high-compression, higher-efficiency baby 4- bangers won't
do the job.

Or they could DONATE the cars to folks who cannot work because they
don't have reliable transportation.

I hate government waste, but hate even more being forced to waste by the
government.

Helping the economy by destroying valuable property, helping the
environment by forcing the (energy intensive) manufacturing of a bunch of
cars.

There's no better tasting mint than a gov'mint.
