Most of us have seen the nodding donkey, nodding up and down. But how does the action of the nodding donkey, pump oil/gas etc. to the surface?

Nodding Donkey (also known as a “horsehead pump” or “pump jack”) provides the up/down motion (stroke) that powers a submersible pump in a borehole. The submersible pumps oil in a similar way to which a bicycle pump pumps air into a tyre. A motor, usually electric, turns a pair of cranks, which by their action raise and lower one end of a metal beam. The other end of the beam, which often has a curved end, is attached to a metal rod that moves up and down. The rod, which can be thousands of feet long, attaches to a pump deep in an oil well.

that was decided during the council of trent. many cardinals and bishops argued over this, it was a month long symposium. The countryside was sorely taxed, taking care of the personal needs of these great men. Several were executed in the process but in the end, nodding came to mean "yes" and the side to side motion came to mean "no". The extent of conviction was indicated by the vigorousness of the movement. If someone asked you if you wanted cream in your coffee, and you did, you were supposed to bob your head up and down rapidly, even VIOLENTLY at least eight times.
