"In 1957, Johannes Juul – a student of Paul La Cour – built the three-bladed Gedser wind turbine (...)The blades were built from steel spars, with aluminium shells supported by wooden ribs. (...) It ran for 11 years without maintenance, generating up to 360,000 kWh per year, but was not repaired when a bearing failed. When the turbine was refurbished and tested in the late 1970s, it performed better than the first wind turbines with fiberglass blades."
