Here you can not only show what's in a rather build a working windmill in small format, that additionally can charge a battery. I'm going to buy myself the other modular systems. A I have already bought.
Whoever finds Lego models or toll can also be accessed here. It would also be suitable for a working diorama of a landscape. Due to the immense size of about 90 cm even nearly the scale fits here quite well. But I would recommend that at least one adult should be present in the construction.
