Imagine living on a remote island and to survive, you must learn how to harness the power of the sun and the wind as well as tap the energy of other physical forces. Explore this adventure with the Power House model kit as you learn about almost every earth friendly energy source under the sun. Wind energy, sun heat and light energy, along with plant and electrochemical energies, are covered multiple times in the 70 experiments and 20 building projects included in this kit. Designed for ages 12 and up you can build a model house complete with solar panels, windmill, greenhouse, and desalination system. You can even build and operate an electric train, windmill, solar cooker, solar hot water tank, hygrometer, electric motor, power hoist, sail car, and more! A perfect gift for the young hands on learner that enjoys creating and experimenting with new ideas.
