A perpetual motion machine

...if you don't count the energy Nature gives :)

"A hydraulic ram... takes in water at one "hydraulic head" (pressure) and flow-rate, and outputs water at a higher hydraulic-head and lower flow-rate... to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started... the ram is often useful, since it requires no outside source of power other than the kinetic energy of water."

Hattip to MG


  1. I am an Electrical Engineer getting into Hydraulics in my retirement.

    Analogous principles in different fields are fun.

    Consider that a 12 volt car battery can be converted to 20,000 volts with a simple coil and breaker points. These have been around since Henry Ford. No transistors were needed.

  2. I forgot to say that the 20,000 volts are used to create a spark at the tip of the spark plug in the car cylinder.
