So how does it get there? How does it build up? Where is the spark arc
or sizzle?


This is a well known phenomenon in Arizona. What else, besides
charged dust particles, could cause arcing at coax connectors
on a perfectly clear windy day?

A large scale demo of this effect can be seen during volcanic
eruptions, when large amounts of dust are thrown into the atmosphere at
high speeds. Lightning happens.

It is not certainty, but particles rubbing against each other do a
pretty good job of building up static.

perfect example. a large scale dry example of colliding dust particles
building an electric field, without need for them hitting a metalic
conductor. dust particles pick up charge by bouncing off each other and the
ground, there can actually be quite a high electric field built up.

Is the charge on those dust particles electron based?
When cave men rubbed amber on wool to charge it up,
was that electrons?

One time at a hotel in Odessa, TX, I walked across a
wool carpet with leather shoes, went potty, and drew
a two inch arc. OUCH!
