The FischerTechnik Advanced Solar Set is an educational construction kit designed to introduce children aged seven and up to the principles of renewable energy. By using a specialized solar rotor that integrates both a solar cell and a motor, you can build three different functional models: a helicopter, a swamp boat, and a windmill fan. This 80-piece plastic set includes all necessary cables, connectors, and construction elements, along with one play figure to add a sense of scale to your creations. The components fit into a compact package measuring 280 x 180 x 65 mm, making it easy to store after you have explored how solar energy is converted into mechanical motion.
