I have to say, I am not impressed with the article... "Perpetual Flight?" I say yes you can probably fly this airplane forever until a motor breaks or something BUT there is a big difference between a single pilot airplane that takes a team of people to ensure it does not have the wings scratched and a commercial airliner that runs on solar. While the airliner is awesome if we can pull it off, I would not be surprised if we were 20-50 years away from that.
