Wind Turbine Kit. Developed with the National Energy Foundation, this quality, easy to use Wind Turbine Kit is working model of real wind turbine. Hands-on and fully interactive, the kit shows how wind power can be harnessed to generate electricity. The kit can be assembled in minutes, is easy to use and has been designed for use in schools, colleges and universities.The wind turbine can be used indoors with fan, or outdoors in the wind to power the electric motor, buzzer or LED, or can be connected to the voltmeter to measure the amount of electricity generated. The rear vane automatically turns the wind turbine towards the wind, even if the wind changes direction.The turbine hub offers combinations of two, three or six blades and the blade angles can be easily adjusted to discover which configuration gives the greatest electrical output.The kit includes set of four gears which can be easily interchanged to test different gear combinations e.g. ratios of 3:1, 1:1 and 1:3, to discover what effect this has on the power generated.Packed weight: 1.29 kgThe kit contains:• Two-part wind turbine (600mm high) consisting of nacelle (top), and tower (base)• Integral clamp to secure the wind turbine to table top or bench etc.• Six turbine blades• Motor module• LED module• Buzzer module• Dual-scale analogue voltmeter• Brass-hub gears: 60-tooth, x 40-tooth, and 20-tooth with 1.5mm hex key• Operating and assembly instructions• Cardboard storage case
