Very high temperature is not the only condition that is conducive to plasma formation. Plasma can also be formed when an exterior source of energy, like an electromagnetic field, is so strong that it tears electrons free from originally neutral atoms. The conversion of a neutral gas into a plasma can occur extremely quickly. There are numerous everyday uses for plasmas. For example, fluorescent lights and neon signs work because of plasma.
Circuit features on microprocessor chips in computers also contain plasma.
Even the exhaust that is emitted during rocket launches is actually plasma, not gas. Plasma is also used to manufacture industrial diamonds and superconducting films. It may be the solution to our energy problems. While the Earth's natural supplies of coal, oil, and natural gas are being depleted, and the burning of fossil fuels creates harmful pollution, fusion is raising the hopes of many scientists. After all, the deuterium in the Earth's oceans is sufficient, through fusion, to energize the world for millions of years at little or no cost to our environment.
