I agree with you on using the coal to run a steam turbine/genny Canadian... but isn't charcoal made from wood?Even if all the gas ran out I'd have an even harder time finding charcoal in a great enough quantity to run a car on it. If you lived next to a coal mine maybe.
Look, and ye shall find...I say charcoal because in my city you can't get any real coal at all. No coal mines around here. And no use for coal. People do use charcoal for their BBQ so that's all there is around here.
