MagniX, based in Washington State, is developing not one but three alternative energy aircraft, with battery electric, hybrid electric and hydrogen electric offerings. Back in 2020, its modified Cessna became the world's largest all-electric plane to take flight.
Two years later, it flew its first all-electric helicopter and its Eviation Alice aircraft (pictured) took to the skies in a world first for an electric commuter plane. Most recently, in 2023, MagniX broke records when its DHC8-Q300 became the world's largest flight-tested hydrogen electric plane.
