So what are the technical advances? A new type of solar cell? A new type of battery? A new material used in the frame or covering of the aircraft?
The TV program I saw said it was a publicity stunt to promote solar cell useage. The big technical advance according to the TV was a seat with a built in toilet.
I thought we already had solar powered drones that could remain aloft for days.
Like that of the Wright brothers, the achievement of something that
hadn't been done before.
