> why don’t these things have generators to charge the batteries while they are moving? Why does it have to be charged off of coal fired and supplied electricity? Here's a little known fact for you - The regular everyday freight trains that you see in the US are electric. The big diesel engines are generators. The wheels are driven by electric motors. There is no mechanical connection between the engines and the wheels. Just mount a big enough generator in the bed of your electric pickup, and you won't have to worry about finding electric charging stations. You just have to keep your generator fuelled up.
