 In a paper delivered to the Philosophical Society of Glasgow on 2 May 1888, Blyth described the wind turbine as being "of a tripod design, with a 33-foot windshaft, four arms of 13 feet with canvas sails, and a Burgin dynamo driven from the flywheel using a rope".The turbine produced enough power to light ten 25-volt bulbs in a "moderate breeze" and could even be used to power a small lathe.Over the next few years Blyth experimented with a number of different designs.
