"Beginning in 1824 Poncelet had essentially shifted his attention from geometry to applied mechanics. Although he had previously studied certain machines and ways of improving them, it was during the summer of 1824 that he achieved his first important innovation: the design and realization of an undershot waterwheel with curved paddles, which possessed a much increased efficiency. The paper he wrote on this subject gained him a prize in mechanics from the Académie des Sciences in 1825. After new trials conducted on full-scale models, he presented a revised version of his study in 1827. Yet, most of his activity at this period was devoted to elaborating and continually updating the course in mechanics applied to machines that he gave from 1825 to 1834." (DSB).
