I watched the youtube video on that page, I can't pretend to understand the physics behind the theory but I sure hope it is real and some day achievable.
BTW you may find Project Orion interesting:

In theory we would be able to achieve 1/10 light speed by blowing up nukes behind a space ship, making it possible to reach Alpha Centauri in 44 years. Obviously not nearly as cool as a warp drive, but possible with today's technology.
That's pretty cool, so we could do the round trip in 88 years. Or maybe jsut stay on Alpha Centauri!
I don't understand the detailed physics either, i'm not sure that they even do.
There's a little corner of quantum physics that says we create what we believe is possible, including quantum physics ;+}
