Static electricity may cause an unpleasant, but otherwise harmless shock, when you touch a door handle or kiss another person, after you have walked just a few steps on a dry, insulative carpet. Static electricity can also cause the slip (or shirt) to cling to your body, computers to go down, fibers to filter, or tankers to explode. But it is also by use of static electric effects that we can clean the smoke from power plants, make photocopies or sandpaper, and separate iron ore and sand or rice and rodent excrements. Static electric processes have taken place on this planet as long as it has existed in its present form, with water vapor condensing to rain; with convective cloud systems developing huge electric dipoles, also known as thunderclouds, and with sand drifting across the desert.
