Interesting article (http://www.nytimes.com/2009/01/04/automobiles/04COAL.html?ref=automobiles) from the NY Times Auto section about a coal-fueled, turbine powered '78 Eldorado GM developed back in the late 70s.

What about the coal and charcoal systems used in some Latin American and African countries during WW II to pwer cars and trucks. I remember seeing pictures of American sedans with contraptions hanging off the trunks that burned coal or charcoal to fuel the cars. I remember my Dad's friends telling me that that was how they ran their cars in Brazil and South Africa durinf the war.

Cheap transportation! I bet it had no power down low though since it was a turbine. They gotta spool up before you got anything. I wonder how it throttled up and down, since turbines aren't responsive like a piston engine. If they had a constant RPM going, which is what I suspect, I wonder how the trans faired on that. I dunno, I'm just talking from experience on helo's in the Army. We use 2 jet engines on a blackhawk. First they gotta spool up. Once they are, they stay at a pretty much constant throttle setting, the pilot has controls to adjust throttle just a tad on the collective stick. But the engines aren't good at changing rpms very fast and they spin at way higher rpms than piston engines too. Maybe that's why this car wasn't produced, reliability issues with transmissions.
