Hey Tiger! The contraption doesn't necessarily make the energy. It is the wind that is bringing the energy in because energy cannot be created, only transferred from one place or form to another. The machine is storing the energy by moving that center block to the top and locking it in place. When the block unlocks, it releases all of that energy (kinetic energy) and moves the gears that move the fan on the right. While it doesn't make energy in the electrical sense, the machine transfers it in the physics sense. Energy is a property that can be transferred from one object to another. The wind that moves the turbine on the left is transferring its energy into the machine. When the gears are rotated by the wind, and they move that center plastic piece to the top, where it is locked in place, the energy becomes stored in the block. Hope this helps explain a bit!
