Inventing Green | The First Windmill Test Apparatus in America This here is Thomas O. Perry’s windmill testing apparatus from 1882. A steam engine hooked up to all that stuff on the top drove the windmill being tested around in a circle at a constant speed. Dozens of windmills got hooked up to this thing and their power output recorded. From the results, Perry optimized the design of the American windmill from the kind you see here to the steel Aermotor-type you probably think of when you think of the Prairie windmill. via ryanpanos
