As long as you have to get the energy into an EV via conductors and not some chemical reaction or swappable batteries, this is utopie.
I foretell you, your house mains will not provide the sufficient punch to charge your EV up in a reasonable amount of time. It´s 50kW max power draw
for a normal private house in Germany, for example. This theoreticaly could charge a tesla in about 2 hours. I´ve read about an article that said
there is a new accumulator type that would theoretically charge in 2.5seconds /80kw and praised the uprise of EV.
Let that settle a bit. What they did not tell the reader is, that you would have to drive up to a grid-switch station or power plant and plug cables
into your charger port that would be as thick as a 22" wheel.
Now what happens if your whole street comes home at 5:30pm to charge their EV?
1) Overall powerdraw will probably be to much for the local transformer station.
2) Even if the grid (meaning transformers, lines, switches) can take that,
3) Gas and coal plants need to ramp up then because the groundload that the bigger coal and nuclear plants provide will not be enough.
I´ve been on a trip with a friend of mine that owns a Tesla S. We have a good charging grid here in Germany. The trip took us 6 hours longer from
Munich to Berlin than with a normal car, driving the same speed.
Wasting precious time now and then to up the charge. Then you arrive there and every charger station is used already.
It´s all nice and cool until you actually have to use the car in a productive manner.
But I recognize we have to start somewhere...
