Sven "Swan" Ostewig (August 30, 1884 - June 27, 1980) was a American auto mechanic of Norwegian-descent and resident at Lee, Illinois, who was claimed in July 1913 newspaper reports to have, along with Otto Bloomberg, a fellow mechanic, and Kinnie A. Ostewig (November 2, 1877 - January 22, 1957), to have devised an air-intake, wheel-based perpetual motion machine. The Ostewig-Bloomberg machine seems to have been subsequently abandoned, while Ostewig, for his part, went on to run a garage and machine shop, and entered an Apperson Jackrabbit in the Indianapolis 500 race of 1916.
