 Now, just as by way of comparison, there is currently a supercharger network that's run by Tesla, and that does about the same thing in 15 to 20 minutes, which is still quite quick. But to be able to do it in under five minutes is potentially a bit of a game changer, isn't it? Because it's bringing electric vehicle charging more in line time-wise with the amount of time you might perhaps expect to spend filling a traditional car with petrol or diesel. How soon will everybody have one of these?
