For all the advantages of electric cars, there is one big disadvantage. If you want to go further than, say, London to Durham, you have to factor in spending 45 minutes at a motorway service station to recharge.
A new technology based on research into nuclear fusion may have found a way to cut that recharging time by two thirds, meaning that electric car users will barely have time to enjoy the facilities at a Welcome Break before they are back on the move.
The British engineers behind the innovation believe that they can achieve this because they have found a way to solve the chief bottleneck on speedy charging. Batteries take a long time to be replenished not because it is hard to get
