Electric land vehicles are becoming more and more common, and so could electric airplanes be in the future.
A team of researchers at the Institute of Technological Sciences have created a prototype of a completely electric turbojet engine. This engine compresses air and uses microwaves to ionize it into plasma. This plasma provide forward thrust to the airplane's engine.
The elimination of fossil fuel means that this kind of engine doesn't emit any carbon, and doesn't accelerate global warming.
The prototype they possess was capable of lifting a 1 kg steel ball over a 24 mm diameter quartz cube. This is a very promising start into reducing greenhouse gases emission, as planes are a big part of the problem.
