A lot of mill turbines were ordered for 'open flume' installation. No casing surrounded the turbine. There was a "stay ring" which contained the control gates (some makers used 'drum gates' to keep it really simple, some used wicket gates, some used a single 'butterfly' type of gate). This stay ring could be set at the bottom of a flume and ...Web

In the United States, Charles F. Brush created the world's first automatically operated wind turbine generator between 1887 and 1888. The machine was a lot bigger than Blyth's, with a 17-metre rotor diameter and mounted on an 18-metre-high tower. The machine turned very slowly and had 144 blades, only producing 12 kW.Web
