A team from MIT is working on developing ionic wind thrusters as an energy-efficient, low-emission alternative to conventional propulsion technologies like jet engines. The new thrusters would use ionic energy, which is created when a current passes between two electrodes. If one electrode is thinner than the other, it creates an air current in the space between them – and if a substantial voltage is applied, the device could produce powerful thrust without the need for fuel or motors.
