An electric one

Ok, so yet gonna be a smart ass.. that's fine.. then I will just say that solar isn't the end game solution that some seem to think it might be.

Solar is the equivalent of a "trickle charger" and I would be surprised if it didn't require three or four days at a minimum to get a decent charge that would allow you to travel fifty miles.

Maybe try again...

Which solar powered ev do you have?
