Watt's Struggle to Improve the Steam Engine

In 1763, Watt was hired by an eccentric professor at the University of Glasgow to repair a new common engine he had. He spent two years conducting experiments to figure out how to reduce the wasted heat problem in steam engines. During these years, Watt started to act like a businessman and partnered with one John Craig in a manufacturing business for optical instruments. Four years later, he invested in a pottery company.
