This could see electric vehicles (EV) of the near future undertaking cross-state or even cross-country journeys without needing to stop at a supercharger for a quick top-up.

It's a particularly appealing prospect for long-hauling cargo movers looking to cut emissions (and costs), as trucks could be fitted with a smaller battery pack that's topped up as they roll. The system could also benefit regular e-drivers, package delivery operators and public transport concerns.
