Settle Hydro - the Archimedes screw
For a view of the location, see
SD8164 : Settle Hydro - a community hydroelectric scheme .
The screw is 7.77m long and inclined at an angle of 22º (information from Settle Hydro website

It was not turning the day this photo was taken - probably due to low river levels after a very dry spell.
