Power transmission is the movement of energy from its place of generation to a location where it is applied to perform useful work.
Electric power transmission with overhead line.
Mechanical power transmission using gears
The flatrod system was an invention of the mining industry that enabled the mechanical movement generated by a water wheel to be transferred over short distances. It was invented in the 16th century a
Power transmission
…the 19th century, mechanical power transmission was the norm. The oldest long-distance power transmission technology involved systems of push-rods or jerker lines (stängenkunst or feldstängen) connecting waterwheels to distant mine-drainage and brine-well pumps. A surviving example from 1780 exists at Bad Kösen…
