Perpetual Clock?

circa 1870: This 'perpetuum mobile', which was supposed to run a clock, was devised by Swedish inventor Bernardis. The mechanism consisted of pairs of glass balls filled with ether and connected with glass tubes, suspended above a water tank. When a ball touched the water, the ether cooled and travelled up the glass pipe to the opposite ball, which then became heavier and sank down - this process continued and kept the whole 'motor' in motion. What the inventor had neglected was the problem of keeping the water cool at all times. (Photo by Three Lions/Getty Images)
