Jacqueline Riley at the Archimedes’ screw power generation plant that she and husband John have installed at Strathdon

Technology developed by an ancient Greek is helping a farmer in the heart of Aberdeenshire generate electricity.

Greek polymath Archimedes of Syracuse is said to have developed the screw in the third century BC to lift water

from low-lying areas into irrigation channels so food crops could be grown. Its use has since spiralled, but the

concept still remains the same in that it has a spiral screw within the metal casing to move the water
