General relativity has given us the GPS, and QFT has provided a big amount of useful technology, from medical treatments to advances in condensed matter. Can QFT in curved space lead to similar advances in technology/engineering/condensed matter? Is there any pratical device or technology at least inspired in QFT in curved space?

It seems rather implausible that results from quantum field theory in curved spacetimes will lead to any technological innovations in the foreseeable future. This is mainly due to the fact that the length scales at which QFT in curved spacetimes starts to significantly differ from ''regular old'' QFT is much, much larger than our Earth.

Hence, it seems unreasonable to try to build any devices which relies on predictions that can only be made using QFT in curved spacetimes. That being said, never say never...
