The details are complicated. For one, for an airship to fly at the edge of space it will need to be big. I mean really big, over a mile long. It would also need to be very light, a gossomer hypersonic airship. Such a vehicle is not suited for flight in the lower atmopshere. This and other factors create the need to a three stage approach.
“Hypersonic airship”, or even very fast airships, are not usual. Orbital airships could use solar panels 24 h/24.
Perhaps derived technologies could be suitable for some AWES to be defined.
