Electrostatic machine by Wimshurst, a British engineer and shipowner, designed in the 1880s, created by Rinaldo Damiani, a builder active in Venice between the end of the nineteenth century and the beginning of the twentieth century. This generator was one of the most widespread and powerful of the time, also being used for the production of cathode rays and X-rays. It consists of two discs made of plastic material, excellent as an electrical insulator. These discs are mounted on a support coaxially at a short distance from each other and when operated by means of the appropriate crank, they rotate in opposite directions. On the external surfaces of both disks, there are thirty thin metal sectors of rectangular shape. By activating the crank the two disks rotate in advance and, rubbing against their shoulders, store charges of opposite polarity on their surfaces. Materials used: wood, glass, plastic and metal. Italy late 19th century, early 20th century.
