It turned out to be difficult to find financiers in Sweden. Ambitions took John Ericsson to the seething industrial nation of England, where he would soon develop into a world-class inventor. However, there were no major successes. After 13 years in England, the disappointed John Ericsson moved on to the United States, in 1839. In his new homeland, he collaborated with mechanical workshops and further developed his ideas with hot air machines. A few years later, John Ericsson became an American citizen. He took out a patent for his hot air machine in 1856. The patent applied in the USA, France, England and Sweden. Thousands of such machines were then sold worldwide. They were easy to maintain and could be run on several different fuels. However, his hot air machines were not as powerful as steam engines. His last major project was an invention he hoped would avert a future energy crisis – a machine powered by the sun. John Ericsson constructed a hot air machine fitted with a mirror parabola which concentrated the sun's rays towards a space where the air was heated and caused a pressure which drove the machine. The solar machine never became the success he hoped for.
