Aviation pioneer Bertrand Piccard is attempting to push the boundaries of sustainable flight again—this time with Climate Impulse, a liquid hydrogen-powered aircraft designed to fly non-stop around the world. Unlike his previous solar-powered project, this one could actually move the needle on commercial aviation’s carbon footprint.

Backed by Airbus and others, the mission faces massive technical hurdles, from maintaining hydrogen at -253°C to ensuring safe, efficient fuel consumption. But if successful, it could lay the groundwork for the future of zero-emission air travel.

Is this aviation’s "Tesla moment," or just another moonshot? Read the full analysis here.
