We talk a lot about electric cars, and it’s evident that engineers are working toward fossil fuel alternatives for our land-based travel. But what about airplanes? In 2019, 18.27 billion gallons of fuel were used by planes. That’s far from carbon-neutral.
Soon though, we could feel less guilty about flying. A team of researchers has created a prototype jet engine that’s able to propel itself forward using only electricity. Their study was published in AIP Advances in May 2020.
