The world's first motorcycle, designed by Gottlieb Daimler, made its first significant test-run. Daimler's 17-year-old son, Paul, travelled from Cannstatt to Unterturkheim and back. Their “Reitwagen” had a wooden frame and wheels. A leather drive belt ran between the engine and large brass gears on the rear wheel. With no suspension on the wheels, the leather saddle gave a very uncomfortable ride, at a speed up to 12 km/hr. The single cylinder engine had a bore of 58mm, stroke of 100mm and a displacement of 264cc's. The engine gave 0.5hp at 700 rpm. Two very much smaller, spring-mounted outrigger wheels provided some stability. This was built as an experimental vehicle to test the new Daimler engine in a proof of concept, which was to power Daimler's first motorized carriage the following year.

The first commercial atomic energy reactor, and the third in the U.S., produced power for distribution. This was the $57 million Yankee Atomic Electric Company's plant at Rowe, Mass., on the Deerfield River. The reactor achieved self-sustaining nuclear reaction on 19 Aug 1960. The pressurized light-water reactor produced 125,000 kilowatts of electricity. The company was formed by twelve New England utility companies which signed a contract with the Westinghouse Corporation as the principal contractor. It was permanently shut down on 26 Feb 1992, due to reactor vessel embrittlement, after more than 31 years of service. Decommissioning began in 1993.
