Thrusters powered by ionic wind may be 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.
These days, aerospace engineering is all about the light stuff: building airplanes with lighter wings, fuselage and landing gear in an effort to reduce fuel costs.
