Thrusters powered by ionic wind may be an efficient alternative to conventional atmospheric propulsion technologies. When a current passes between two electrodes -- one thinner than the other -- it creates a wind in the air between. If enough voltage is applied, the resulting wind can produce a thrust without the help of motors or fuel. Researchers have now found that ionic thrusters may be a far more efficient source of propulsion than conventional jet engines.
