MIT proof-of-concept demo of ionic wind propulsion for aircraft

Green Car Congress

MIT researchers have demonstrated that an aircraft with a 5-meter wingspan can sustain steady-level flight using ionic-wind propulsion. The MIT team’s final design resembles a large, lightweight glider. In this way, the batteries supply electricity at 40,000 volts to positively charge the wires via a lightweight power converter.
