Fastronauts are green kids gadgets powered by play. Fastronauts, created by Sara Paculdo, have rechargeable batteries and dynamos.
If kids attach them to their bikes, roll, crank, spin, or perform any other type of movement, the batteries are recharged through the kinetic energy conducted.
Fastronauts have power indicators that can be pressed to make them talk, giving children instant feedback on the energy they created.
Fastronauts are a great green kids gadget to teach about eco-friendly energy production in a playful way.
