Whoever comes up with a FAST rechargeable battery that doesn’t deteriorate and has enough energy storage capacity for a car to go 200-300 miles on a charge will be a gazillionaire..................
About 4 decades ago I built an electric motorcycle. But the lead/acid battery pack made it useful in too limited a way. The battery guys at the time weren’t willing to help much so I mothballed the project. I always thot chemical storage of electricity was the wrong way to go. Rather using a method more like a capacitor would have given the quick charge necessary to be practical. But I don’t have time to do everything. So I’ll still drive punched out big blocks until I get some help.
