How about re-inventing air travel why we’re at it: Airbus is working on a solar energy-powered plane that can stay airborne for up to 120 days. The Zephyr plane is not meant for transporting passengers, but actually weighs just about as much as an average person would, according to the BBC. Instead, the plane’s ability to say in the air for so long means it can be used as a communications platform that is even better and more accessible than satellite. “Zephyr will provide the potential to revolutionize disaster management, including monitoring the spread of wildfires or oil spills,” the head of the program at Airbus, Sophie Thomas, said (watch here, runtime: 1:07).
