taken 10 years ago, near to Aberdulais, Neath Port Talbot/Castell-Nedd Port Talbot, Wales
Waterwheel - Aberdulais Falls
This National Trust site generates electricity from the river by both a waterwheel and a turbine. The wheel is 8 metres diameter and weighs 16 tonnes. It was built by British Steel in 1992 and is now nearing the end of a major refurbishment that should have it generating 20 kW for the site and for grid export. The wheel is an overshot suspension wheel and drives an alternator via a gearbox. The wheel is started by using the alternator as an induction motor. The original wheel in this pit drove tinplate rolling mills.
