Electric cars have been around a good long time. I have a circa 1800 auto repair manual which shows maintenance on an electric car. Shows how the electric motors switch from series to parallel circuit, and how to change the plates in the glass battery case.
A couple of points no one who supports electric want to address: one, there is no recycling program in effect for the batteries, and modern batteries are highly toxic. It is going to create huge pollution.
Two, electric cars don't eliminate pollution, they shift it to the power plant, creating point pollution compared to non point pollution.
Seems to me we should address the long term problems before establishing alternative power.
