<P> James Watt 's later engine design was an improved version of the Newcomen engine that roughly doubled fuel efficiency . Many atmospheric engines were converted to the Watt design , for a price based on a fraction of the savings in fuel . As a result , Watt is today better known than Newcomen in relation to the origin of the steam engine . </P>
