Well, it's always been the suggestion that it's the *moving air* that generates static electricity, with the velocity being the major factor. The direction shouldn't really matter, though I was pointing out that you generally have more force with an airstream that blows rather than sucks. One only has to have a cleaner with both inlets and outlets attachable to the same hose to be able to notice the difference (expelled air having significant force a few feet away, yet a sucking hose having almost no power a few inches away). Service shops used to use air compressors (as used for power tools, and inflating vehicle tires) to blast muck out of electronic devices. And, in doing so, would often cause static electricity damage. No vacuum cleaner there, and a similar plastic hose, metal nozzle, issue. I'd be more concerned about vacuum cleaners with: Getting the nozzle too close, suddenly sucking itself into direct contact, and smacking into delicate parts. Than with a static charge that they might generate. -- [tim@localhost ~]$ uname -r 2.6.27.25-78.2.56.fc9.i686 Don't send private replies to my address, the mailbox is ignored.
