Orffyreus's perpetual motion machine, illustration
Orffyreus's perpetual motion machine. Illustration of the 18th-century perpetual motion machine designed by German inventor Johann Bessler (c.1680-1745), also known as Orffyreus. Bessler first exhibited his invention in 1712, building successively larger demonstrations, culminating in 1717 in a wheel 3.7 metres in diameter able to lift heavy weights. The internal mechanism was thought to be a system of pendulums forming an overbalanced wheel. Bessler tried to sell his invention in the courts of France, Austria and Russia. An external source of power would have been required, as perpetual motion machines are a theoretical impossibility. In 1727, a former maid of Bessler gave an account that the machines were operated manually by a concealed mechanism.
