Do you think this makes any sense? - Continuous Motor - Boyle's Vase. One of Robert Boyle's most curious inventions is known as the Perpetual Flow Vessel, or Self-Flowing Vessel.
The principle is quite simple: the weight of the liquid in the vessel is significantly higher than the weight of the liquid contained in the neck of the vessel, this causes a difference in pressure that makes the water rise up the neck of the vessel. Thus, the liquid is forced to flow in order to compensate for the difference in weights (hydrostatic pressures). If this compensation is sufficient to raise the liquid from the neck to the upper area where the tube ends, the system acquires a continuous behavior of compensation of pressure differences.
Unfortunately the theoretical foundation is wrong as it confuses weight with pressure, and therefore this would never work.
