Just shuffle your feet on carpet... a LOT.
What's funny is that something like this happened at the gym I go to. It was a particularly good day for static, and I noticed when I got on a trampoline, I could feel an electrostatic field around me, on my arm, leg, and head hair. Then when I jumped in the air away from the trampoline bed, the feeling would go away, then come back as you neared the bed again. Needless to say, it was pretty weird. I can only imagine what it would be like on an industrial level. O.O
If we could scale this down (if only.), you'd be able to do everything from having energy shields to force pushing people! 8O
