If I'm not mistaken the "Stanley Steamer" had the land speed record in the 1920's at 104 or 106 MPH! Steam is the earilest from of power! The first excavators were "steam shovels" and cranes were steam powered, and what about the "steam roller"?
All of those machines and many more were the ancesters to the modern equipment of today! If it wasn't for the transoprtation lag in the planes states, and the fact that there wasn't much to burn for fuel, gasoline and diesel might have took longer to catch on here in the US. The only other problem with steam engies were their tendensies to blow up! I guess trying to overrev or get that extra horse power lead to operational no-no's back in the day! Poor or lack of maintenance, and just abusave operations was more the problem then the solution!
