Nasa has awarded $100-000 in funding for the Supersonic Plane Concept which claims a flight time between New York and Los Angles of two hours

got the cash to refine the design, run simulations and do some wind tunnel testing, with the potential for more funding in the future. Unfortunately, the concept is, at best, decades from becoming a reality,

Amazing Concept will it ever fly

Concepts are "a dime a dozen" and nothing more than an initial ideas phase of any design, and as has been pointed out $100k is barely enough to rough out a rational concept - deciding if it feasible will cost multiples of that - way back "in hte day" Boeing wrote off a lot more than that on the SST-2707 for example.

Off the top of my head - folding wingtips were proposed for the 777 - but that was for ground use & with a substantial weight penalty - no-one bought them. Making them fold, in flight, for a supersonic a/c is going to be tricky.

Pivoting engines? A tough act to get right - e.g. the V-22 - pivoting intake & exhaust might be more feasible.

Supersonic flight over mainland USA wasn't allowed for Concorde due to the sonic boom - will this design get past that barrier(sic)?
