Will production aircraft have a different propeller design?
Lots of concept aircraft with revolutionary designs have come and gone over the years, only a very few have gone into production.

Peter Garrison has a good article. It is a positive maybe!

"Well, I thought, the magic number must be 65,000 feet. Sure enough, here, 500 hp yields 430 ktas—at 120 kias—and 17 nmpg. A more realistic cruising power of 400 hp yields, well, nothing, because the minimum power required to sustain flight at this altitude, at 325 ktas, is 425 hp.
We seem to be in the ballpark, but the Celera may encounter several difficulties on its way to FL 650."
