G-windmill / plaything


At the same time of bringing the children a lot of pleasure, G-windmill transfers wind energy into electricity, to light up the LED among its vanes. As we know, in third world countries, there is much barren ground, where has no electricity. People there have much inconvenience in darkness. By rotating the vanes, G-windmill could store energy. While pressing the switch in the stick, the LED will shine, just like a flower, giving warmth to the children. Besides, G-windmill is made of recycled paper which do no harm to our environment.
