Question: Is it possible to make solar-powered airplanes?

Martin McMahon answered on 24 Mar 2025:

Yes it is, and in fact this has already been achieved by Solar Impulse, and this year marked the 10th anniversary of that success. On 9 March 2015, the pioneering aircraft took off on its record-breaking journey, proving the potential of solar energy. The record-breaking flight was made by the Solar Impulse 2 airplane.
