You could, if the accelerations were slow enough, and you did not smack into the atmosphere like a brick wall,

Thats the idea behind zeropto,

Make a hole in front of you, and move that air behind you,

gettting both thrust, and a lack of friction based heating,

Absorbing friction and outputting energy would work as well,
as long as the craft was heavy enough to not slow down when smacking the atmosphere, (killing you with G forces)

So a HEAVY craft, with extreme cooling tech, would not need zeropto...
as long as it left the ground going fast enough (more the escape V, or had a engine to compensate for drag, it would do fine.

Heat shield that makes energy :D

You see, that's why you need to do the maths. You'll need one heck of a lot more energy to move air around a big heavy craft at supersonic speeds than this is going to provide.

Incidentally, I'm tempted to write a peer review for this "article" you linked to, because it badly needs one. They've formatted it sort of to look like a scientific article, but it's not nearly good enough for publication in any decent scientific journal. They're describing way too much in one go, references are missing everywhere, methods of the experiments performed are unclear, there's no discussion of the results, no clear embedding in the literature, the introduction is a big list of non sequiturs, and so on.
