This device uses chemical energy (Battery cell) converted into Electric energy (Motor motion) to generate mechanical energy and this mechanical motion moves an electric generator to generate electric energy again a light-up LED, Light Energy

This economical energy conversion kit lets you experiment with conversion between two different power sources – mechanical motion, light energy,  & chemical energy. It’s an excellent hands-on project for ages 8+
