They're planning on carrying some sort of ballast, the video shows the
ballast to be h20. They could carry L02 as ballast instead and use it at
higher altitudes.

So it's a dirigible instead of a balloon, and you burn the hydrogen in the

Not much mention on how they deal with aero drag.

They also seem to be burning helium with atmospheric oxygen ... I didn't
know that worked well enough.
