Design and construction

In 1833, while living in England, Swedish engineer John Ericsson patented his first caloric engine. After emigrating to the United States, he continued making improvements to the technology, until by 1850, he had built a total of eight such engines, the last and largest of which had a cylinder bore of 30 inches (76 cm). At this point, Ericsson decided the time had come to test a caloric engine in the most demanding of applications—as the powerplant for a full-sized oceangoing ship.
