Sure have - but lightweight, single seat vehicled with large, flat top surfaces covered with solar cells. Specially designed to race across Australia. Airplanes have already demonstrated powered flight with all power coming from solar panels. Yep, and one even flew round the world on solar power. But lets not forget that it was huge, a single seater, flew at 35-40 kts and took weeks to finish the journey. You're speaking of the Solar Impulse 2? Took a year and a half, a large support team of meteorologists, a cargo plane following them carrying a huge inflatable hangar, and lots of supplies. They fried their batteries and had to replace in the field. A noble experiment, proved it could be done, but also proved it's a hell of a long ways from being practical. https://www.youtube.com/watch?v=4qbROmxxIOU |
