A kit comprising 8 solar modules, low-inertia motor, impeller, connecting lead and copper links for cell interconnections and housings and brackets to enable the construction of various solar powered projects. The modular concept of this kit enables experimentation with differing voltages and currents to produce the required circuit. The kit also includes comprehensive booklet covering principles of solar power, together with useful connection diagrams and output calculation formulae.

This wind turbine can be used to carry out wide range of experiments on wind power. The blades of the wind turbine can easily be attached, removed or adjusted, allowing students to investigate the effects of changing the number, pitch, size and shape of the blades. Some of the effects can be quite counter-intuitive and require students to think carefully about the concepts of energy and power. With mm sockets attached for easy connection to other equipment, the electrical output is DC. Assembly required. Contents: generator assembly 1, support post 1, turbine hub 1, turbine blade posts 6 and turbine blades 6.

Wind is one of the most promising sources of clean, renewable energy available today. Wind energy has been used for centuries to pump water and crush grain in windmills, and is now increasingly being used to generate electricity to power our modern world. Using this kit you can assemble a wind turbine complete with electric generator, adjustable rotors, and wind speed indicator, then conduct more than 20 experiments with your wind turbine. Experiment with different numbers of rotor blades, different blade angles and profiles, different wind speeds, different gear ratios etc. Use the wind turbine to generate mechanical power to lift heavy weight or generate electricity to light up an LED and charge rechargeable battery. Includes full-colour, 32-page experiment manual with illustrated instructions and scientific information. • Build working wind turbine • Harness mechanical energy to lift weights • Generate electricity to light an LED and charge battery • Learn the physics of wind turbines • Discover how wind occurs and why it is such promising energy source • Learn about the physics of force and motion as it applies to wind power technology. • Learn how to measure and calculate the different forces acting on the rotor blades by breaking them down into vectors • Discover how the sun makes the wind, providing us with an endless source of energy • Read about different types of wind turbines and windmills

Developed with the National Energy Foundation, this quality, easy to use Wind Turbine Kit is a working model of a 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 a 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 a 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 kg The kit contains: • Two-part wind turbine (600 mm 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
