The Hydro takes the form of a 'reverse' Archimedes screw. (Whereas a classical Archimedes
screw uses power to lift water upwards, here it is the movement of water downwards under
gravity that creates the power.) The screw was installed in August 2008 to generate
hydroelectric power for the local Co-op supermarket and for feeding into the National Grid.
When working at full power it produces about 30-50kW. In April 2015 the total power
generated since August 2008 reached 1,000,000kWh. The Hydro exploits the fall in water
level created by the weir, originally built for the water-powered Torr Mill: a nice case of
