Stratsat had electric motors and a back up diesel. The new idea seems to be propulsion by climbing and gliding by varying buoyancy. How capable of handling strong winds this would be I would question. I can see that diurnal temperature changes could provide the main power source for propulsion during long flights but I can’t see high speeds being achieved like this.

At what levels do they think that thing would operate - and what would be the extent of its vertical meanderings? Would they be predictable?

Or here is a revolutionary thought! Rather use the power used for the air pumps to drive a propellor fitted on the nose. Steady state speed, so should be more efficient.
There is a whiff of “something for nothing” about this proposal. For example, air is being pumped ‘in’ when outside pressure is at its lowest and ‘out’ when at its highest.

Uses a similar principle to submarine autonomous 'gliders'

Weirdly a decade or so ago I met a couple of bods who were thinking of pitching a similar concept to MoD and DARPA, albeit with a few notable differences. As far as I know neither are involved in this company.

Lower limit = watch out for those cows!
Upper limit = did you just hear that loud pop?
