Move over electric cars, here come electric planes:

Luckily, electrification isn't always an all-or-nothing proposition, especially in a plane with several engines. A new partnership from Airbus, Rolls-Royce and Siemens appears to take advantage of this fact. Dubbed the E-Fan X, this will be a demonstration hybrid aircraft which—initially—will have one of four gas turbine engines replaced by a two megawatt electric motor. But as the system matures, is demonstrated to be safe and, presumably, as battery costs come down, provisions will be made toward replacing a second turbine with another 2MW motor.

A big part of the motivation for projects like this is, apparently, the European Commission's Flightpath 2050 Vision for Aviation, which includes a reduction of CO2 by 75%, reduction of NOx by 90% and noise reduction by 65%. The happy side effect, presumably, will be cleaner air, lower dependence on fossil fuels, and cheaper flights too.

If they put solar panels on top and wind turbines on the wings, they can recharge while they fly.
