Airbus has dreamed up a new line of eco-friendly planes called the "ZEROe.' The concepts are all powered by hydrogen, and all could start ferrying passengers by 2035 according to the company.
That could mean that, instead of greenhouse gases, the planes emit water vapor...
It's not the first such plane concept. Wright Electric unveiled plans in 2017 for a 150-passenger all-electric airplane that could fly 300 miles.
Airbus previously worked with Audi and Italdesign on the Pop.Up Next, a concept vehicle that could transform from airplane to car.
