When Thales rubbed a piece of amber in 600 BCE, he realized that it had the power to attract lightweight materials such as feathers, fibrous textiles and other items. The museum, founded in 1988 in order to celebrate the silver anniversary of the National Electricity Board, uses this episode in history as a springboard for charting the history of electrical energy. Original relics and replicas of machinery, as well as newspapers and publicity cards are on display in vast rooms. There is an excellent replica of the internal set up of the hydroelectric power station in Alcantara in Sicily, complete with original machinery and models of plant workers. Documentation of studies and research by Leonardo da Vinci and Galileo also exists. Admission: Free.
