Here is some of the technical info on how this new device would work:

Each element for the rocket — including boosters, engines, stages and Spacecraft and Payload Integration & Evolution (SPIE) — undergo their own reviews before this week’s kickoff of the integrated program review. Boosters, stages and engines have passed their critical design reviews, and the SPIE Office is in the process of completing its critical design review. SPIE is responsible for the design and development of several parts of the top of the rocket.

Now a lot of people have discussed the warp drive concepts from NASA but this is obviously a more practical iteration.  Could you imagine what this would be used for?  Possibly sending people to Mars in a few weeks?  Or something else?  Here is also a cool video enjoy!
