Wood and selected biomass are available free in many locations, but there is significant labor and a bit of hazard sorting, and cutting it, and stoking the wood burner, which powers a steam turbine which powers the rear wheels = all the torque you could possibly want when the fire is burning well. At start up and poor fire, the front wheels are electrically powered by a small battery, which assures at least 45 mph except up the steepest hills. The catelytic converter for home wood stoves, is already mature technology, so EPA should be agreeable. A device similar to an electric charcoal lighter can likely get the fire started in a few minutes, powered by the battery which can be charged by the steam turbine when there is surplus torque or steam available.
Typically a few minutes connected to the utility would bring the battery to full charge, or you can keep the fire burning and power your house significantly when the car is at home. Possibly your car can preheat the hot water for the hot water tank which can significantly heat your home. Please refute, correct, embellish and/or comment. Neil
