Anything that uses an electric motor can use a smaller more efficient motor, id expect big changes in e.g. electric cars, but also probably things like robotic actuators getting smaller and more efficient. Also there are superconductor based batteries that are very efficient, would would become a thing, likely revolutionising batteries.
