Hot Air has a bit on another coal-powered car. It's small, natch, has 3 wheels, which makes it a motorcycle in many states, and runs on compressed air.
Top speed is 40 KPH and range is 150-200 Km which puts it firmly in the same range as a golf cart, but not as good as the Tuk-Tuk.
They also put the single wheel up front, which is a disaster waiting to happen. They didn't go into what it was made of, but fiberglass, one layer, seems to be a good guess. As a motorcycle, that's one more layer than you usually get, and in the winter I appreciate all the layers I can get.. No big battery is required, but a middling sized one would be required to run things like headlights and maybe a heater.
I suppose you could turn this into a hybrid by adding a small contractors compressor in the boot, running on gasoline to pressurize the tank.
