Re: " the electricity to do it in reasonable time"

"If you charge your phone for an hour can you make an hour-long call? Like fuck you can, it'll be lucky to give you 15 minutes. Same for a car.

I are physicist. What you?

A chartered electrical engineer."

I am neither a physicist nor a chartered electrical engineer, but my phone takes a little over three hours to charge and a 1 hour 3g phone call drops the battery charge by typically 10%.

Reminds me of an account many years ago in Wireless World about some poly lecturers arguing in the lab about the phase of the AC voltage out from a coil with co-wound primary and secondary. It took some time before one of them went and got some wire, some ferrite, and hooked it up to a signal generator and an oscilloscope.
