The guy who invents a small LNG tank with a very small (car size) reliquefaction device will revolutionize the world. There are huge innovative hurdles to doing this. Currently, NG vehicles rely on CNG (commpressed) which ends up having the same problems of electric, although a little better,crappy range. LNG to NG ratio is 600:1. So a tank of LNG would last you a long time. The big hurdle is that it has to be stored at its boiling point, -260˚ and is constantly boiling off NG. So two issues to resolve, cryogenic storage (which exists in large scale already) and preventing the tank from exploding from overpressure.
