Wind power will blow you away!
Build six awesome bots that move without any batteries or electricity. The secret behind these fascinating machines is one of the oldest power sources in the world: wind! A full-color manual guides you in assembling six models, one at a time from over 130 pieces.
Build a big-wheel tricycle, quadruped, soaring machine, drilling monster, walking robot and even a wind-powered yacht. To make them all go, the kit also includes the pieces to build a hand-powered wind generator. As you build and experiment, you will learn about how gears transmit power and torque. Also learn about wind as a power-generating technology — past, present, and future.
