Seriously though. What is your vision for this car?
I'd love to see what one of my steam engines could do in this car.
My steam generator design is able to generate a full head of steam in 30 seconds (less time it takes for your garage door to open).
My expansion motor design is capable of extracting 1 hp hr per 5.5 pound hours of steam. This makes the entire unit more energy efficient most diesels, with the ability to run what ever liquid fuel you got.
