Staff and volunteers at Cragside are celebrating the first anniversary of the return of hydropower to the former home of Victorian engineer William Armstrong.
This coming Wednesday is a year to the day that actor Robson Green officially switched on the Archimedes screw at the Rothbury property, relighting the house – just as Lord Armstrong did in 1878 – with water.
At the beginning of July, the Archimedes screw had produced 13,669kWh of electricity; energy to illuminate all of the lights in the house – which total more than 350.
To make this system as efficient as possible, Cragside is fitted entirely with LED lightbulbs. The launch of the screw continued and fulfilled Lord Armstrong’s dream of lighting his home by using hydroelectricity.
