mmm candy
wait, who said flying cars? how bout.. flying CARpets made of this stuff, and they're combined with the transparency/camoflauge camera/projectors, so you could be invisible in the sky from below.. The B-2 Stealth Carpet.
Or, you could sell advertising rights for the bottom of your carpet, it would be broadcast ad-space, a la the blimp in Bladerunner..
of course.. it only makes sense if these carpets are driven by giant sharks with lasers attached to their heads
