Precisely. This is an incredibly easy problem to solve. See all the Rutan projects, the model plane that crossed the atlantic, etc; most from over a decade or more ago.
They claim that solar efficiency is not there yet, but look at the NASA Helios. Yes, it's large, but such is life if you want solar. The math behind it is incredibly simple.
Yet, as usual, HN is foaming at the mouth because it has the word drone in the title.
Edit: this is just another MIT fluff piece. Watch the video, it's a carbon fiber tube filled with random COTS hobby grade components. With a hot wire and some composites knowledge you could make this in your garage.
