Solar-powered aircraft

Short description: Flying sun-powered vehicles

NASA's Pathfinder prototype

Solar-powered aircraft are electric aircraft that can be an airplane, blimp, or airship and use either a battery or hydrogen to store the energy produced by the solar cells and use that energy at night when the sun isn't shining. Conventional passenger or cargo aircraft aren't practical yet with modern technology, but high-altitude platform stations and long-endurance missions over a fixed location with unmanned aircraft or airships are feasible and could be beneficial for telecommunications, video/imagery, radar for flight control, weather radar, and other pseudo satellite[1] applications that transpond the data with ground stations. Solar powered aircraft do not require fuel, so they don't require oxygen, and they are able to operate at altitudes over 20 kilometres (12 mi) to 100 kilometres (62 mi) for months at a time.[2][3]

## Solar airships

Stratobus high altitude airship

Solar Airship One is being developed by Euro Airship and is planning to launch a would tour in 2026 and fly by 25 countries in 20 days as it travels around the world non-stop. It will be autonomous and use electrolysis to store hydrogen to keep moving at night when the sun isn't shining.[9]
