Sure seems to me the answer is to use the waste heat off the electric motor. (there's plenty of it in normal driving).

But if you only used it when needed, such as for long trips where you need maximum range for your EV, you would only consume about one gallon per year, an absolutely trivial amount. So I think heating with fuel should be a standard feature for electric cars. -- Larry Gales On Mon, Oct 27, 2014 at 9:24 PM, Jan Steinman via EV <ev@lists.evdl.org> wrote: > Perhaps this is a sacrilege on this list, but I'm planning to provide > cabin heat in my 1981 Electranagon with... diesel fuel! > > I got hold of an old Webasto hydronic heater.
