Calvin C. Williams and his twin sons began experimenting with steam cars in 1940, and by 1957 were advertising that they would build complete cars, or convert gasoline autos to steam power. At least one original car was built, using a flash boiler, 4-cylinder single-acting engine, and fiberglass body. In 1966 they were offering a steam converted Chevrolet Chevelle for $10,250, and received orders for nine of these, together with one for a Ford Fairlane from the Ford Motor Company. However difficulties in obtaining small quantities of components at reasonable prices delayed the project, and rather than raise extra capital, the Williams closed their business in late 1968.[1]
