 In 1895 he licensed the Glasgow engineering company, Mavor and Coulson, to build a second, improved turbine, which was used to supply emergency power to the Lunatic Asylum, Infirmary and Dispensary of Montrose; the system operated successfully for the next 30 years.Blyth's original wind generator was the first known structure by which electricity was generated from wind power, but its lack of a braking mechanism meant it was prone to damage in strong winds.In the winter of 1887, some months after Blyth's first wind generator was built, American, Charles F. Brush built the first automatically operated wind turbine.
