Quote "The power and economy of that engine were fact. The Hot Vapor engine patent rights were never sold for production and are now public domain. Every major motor company; foreign and domestic looked at it. Several branches of the armed services as well. Human resistance to change, extreme cost of retooling and some bad blood from previous motor company experience combined to prevent it’s success. There is one in the Smithsonian. There are more than one running examples in private collections."
