neutral dust can gain an electrical life (http://www.scientificamerican.com/article.cfm?id=swirling-dust-lightning&sc=DD_20100412#comments)
"But the mystery isn't entirely solved. For one thing, the team still hasn't explained the origin of the external electrical field needed to kick off the charging process. Shinbrot thinks it may be possible for moving clouds of dust or sand to self-generate fields. But Lacks suspects that unknown mechanisms may also be contributing. "Everything seems right," says Lacks, "but I don't think this is the final story."
So :)
Any ideas to how the mechanism(s)behind it might look?
