Coincidentally, in 1807 Nicéphore Niépce installed his 'moss, coal-dust and resin'-fueled Pyréolophore internal combustion engine in a boat and powered up the river Saone in France to be granted a patent by the Emperor Napoleon Bonaparte. The discrete, virtually simultaneous, implementations of these two designs of internal combustion in different modes of transport means that the de Rivaz engine can be correctly described as "the worlds first use of an internal combustion engine in an auto-mobile (in 1808)", whilst the "Pyréolophore (in 1807) was the world's first use of an internal combustion engine in a ship".
