Climate and environmental protection are key values in today's world – that’s why we are working to teach kids about this important issue through play. To learn about generating, storing and using electricity from natural sources, children can build exciting models that move using wind, water, or solar power and teach them about applied technology in a fun way. This helps stimulate their interest in these types of energy, which will become even more important in the future. The H2 Fuel Cell Car (Art. no. 559880) is a great addition. This expansion set can be used to build additional models that run on a fuel cell.
