Why is it unlikely that the vacuum could create static?
That is not a proper question, much like: "Why is it unlikely
that reading ComputerGuys-L could give you boils?" is not a
proper question.
If you know why moving air with a vacuum cleaner would cause
static, please let us know.
(IIRC - always a guess)
It's the movement of air molecules over some surfaces. Some
small number of electrons are left behind. But given that
you are sucking gobs of air throught the hose, it could be
quite a few electrons being left behind. Similiar to the
way that vanDeGraaf(?sp?) generators work. vanDeGraaf
generators can produce huge static charges, vacuums not so
much. If you have ever been flying and noticed those little
wick things on the trailing edges of airplane wings, those
are supposed to drain the static charge that accumulate on
airplane wings. I take the smart guys at their word and
believe it them without really understanding the details.
