If the claims are true and we can make it cheap enough... Change all electronics. You know all the fans in your computer? That's because heat is radiating off the silicon causing wasted power and limiting the amount of transistors possible based on cooling available.

All of our power lines(especially the long distance ones) are high voltage because of power loss in the copper, that's why there are local transformers in your neighborhood (these failing are a common cause of neighborhood black outs).

Want a electric car with high efficiency? Alot of heat is wasted by the copper windings in the motor. That goes away and range would increase dramatically.

Again this is all assuming the claims are legit and we can manufacture it at a decent price.
