Product description

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.

  • Easy, snap-together assembly requires no glue
  • Step-by-step, illustrated instructions
  • 6-in-1 engineering kit: build six wind-powered models and a handheld wind generator. Start cranking the generator and watch them go!
  • Learn about gear ratios and wind-power technology.
  • No batteries or electricity required
