Model. Dr Stephen Demainbray (1710-1782), a science lecturer, was given this model by the Marquis de Grollier when he was in Lyons, France in 1754. The model is made of oak and consists of a platform supporting a tower with a water wheel on one side. There appears to have been no function for the small windlas under the tower. A swiftly running stream was necesary and so tidal rivers would have been inadequate. It is a very simple device which probably delivered little power.
