I wonder if battery technology will ever reach the point where those able to charge at home (and there are many who cant) would be able to charge a home based storage battery 24/7 using solar panels . This battery could then charge the car without having to pay anything to windfall tax dodgers.
Or universal batteries where you literally plug in a new one at any filling station on an exchange basis, leaving one behind for recharging. Like a calor gas cylinder.
I did read a while ago of a portable battery that could give EV's a few extra miles of range. But IIRC it was only about 20 miles or so, and it was the size of a suitcase. And cost thousands - they were trying to market them on a leasing deal. . They did exist, but probably never a viable idea. At least with todays battery technology.
Lots of reasons why not. Perhaps I shall go and invent one, and let some of my wealth trickle down to the minions.
If I inspire you to make your fortune, remember you heard it from me first and I dont mind being generously trickled on.
