Power House: Experiments in Future Technics provides an engaging introduction to renewable energy while teaching basic concepts and principles in physical science. The kit focuses on the heat and light energy from the sun, the energy from the wind, as well as with electrochemical and plant energy. You will learn how to transform and use these forms of energy. With this Power House kit you can build a model house complete with solar panels, windmill, greenhouse, and desalination system. You can build and operate an electric train, windmill, solar cooker, solar hot water tank, hygrometer, electric motor, power hoist, sail car, and more. This product is available through many online retailers.Power House set comes with 70 experiments and 20 building projects including: *The Heat Trap: Construct and experiment with a greenhouse *The Sun Furnace: Collect the sun’s rays to heat water *The Sun Burners: Make a solar cooker while learning about the principles of light before you cook rice and bake bread *The Water Vampire: Desalinate water, plant watercress, produce sauerkraut and make chewing gum *The Heat Absorbers: Learn how heat of evaporation provides cooling, conduct experiments about air humidity, build a hygrometer and test a refrigerator *Power and Plants: Grow beans, make a potted plant feed a candle, harvest sunflower energy, build an oil press, and assemble an oil lamp *The Energy Converters: Extract electric current from sunlight and metals in acid, build a light telephone, galvanize a nail and split water into hydrogen and oxygen *The Forces of Magnetism: Generate electric current with magnetic fields *Wings in the Wind: Build a sail car and learn how wings and sails transform energy. Learn to sail with the wind, by the wind, and against the wind and examine a mixed energy vehicle.
