I've come across a guy building a steam car. It uses a Riello Central Heating Boiler Burner, powered by a bank of 12 volt batteries driving an inverter to give 240V for the burner motor. The control rods for the steam plant look like Titanic Pattern Parts, and I reckon to drive it takes two, one to drive and one to control the steam pressure. Road legal? No f....g chance!!!!
