So to alleviate the device's requiring prohibitive amounts of energy to operate, it just needs to be made out of particles that haven't even been encountered.

You don't have any unobtainium in your garage?

Seriously, the "original" Alcubierre drive also relies on exotic matter. The "breakthrough" that is claimed in this article is that modification of the geometry of the warp bubble reduces the energy requirement from "astronomical" to merely "large".

ZPE. Field theory to "flip" matter to anti-matter. Tap the quantum foam directly for power.

Energy may not be the tough part here.

Even an "exotic" material will need to interact with space/time in ways that nothing else has been able to do that we have found to date. I'm interested in seeing exactly what criteria they think will be required to get this perturbation of space/time to occur within their parameters.
