G. HOW DOES THE GENERATOR WORK?
Your wind generator turns the energy in the wind into light that comes from the LED
(light-emitting diode). The wind pushes on the rotor blades, making the rotor turn, always in
the same direction. The stronger the wind, the faster the rotor turns. The gear wheels make
the shaft of the motor turn many times for each turn of the rotor. The motor actually works as
a generator. Inside the motor is an armature attached to the shaft. The armature has hundreds
of turns of wire around it. Around the armature are permanent magnets. When electricity is fed
into a motor, it flows through the armature, turning it into an electromagnet. The armature is
repelled and attracted by the permanent magnets, making it spin. In your wind generator, the
motor works in reverse. When the armature is spun round by the shaft, the magnetic field
made by the permanent magnets causes electricity to flow in the wire in the armature. When
the shaft is turned fast enough, the electricity generated is strong enough to make the LED
light up. The wind generator's tail keeps the rotor facing into the wind

5. You are advised to wear eye protection and gloves when the wind generator is working,
as strong winds may cause parts to fly off
B. BEFORE YOU START
To complete the wind generator you will need a clean plastic drinks bottle and a small
cross-head screwdriver - these are NOT included. Carefully identify all the following parts

• The most powerful wind generator in the world is the REpower 5M. Each of its three blades
is 61.6 metres long. It produces enough electricity for 5,000 houses.
• A small wind generator can supply enough electricity for a home, school or small factory.
• The world's largest wind farm is the Horse Hollow Wind Energy Center in Texas, USA. It has
a total of 421 generators. It will produce 735 megawatts of power, enough to boil half a
million kettles at once.
• Offshore wind farms are wind farms built at sea, where the wind is more consistent in
strength and direction. The wind generators sit on pylons resting on the sea bed
• Engineers are designing and testing airborne wind generators. These will float thousands of metres above
the ground, where strong winds nearly always blow
• Wind generators are a clean and renewable way of producing energy. But they are useless
when the wind stops blowing! So we need other forms of renewable energy, too.
• Ocean turbines are like wind generators under the sea. They capture the energy in the
currents caused by rising and falling tides
• Plastic drinks bottles like the one you recycled for the wind generator are normally made
from a type of plastic called PET (short for polyethylene terephthalate)
• PET bottles are recycled to make hundreds of different objects, such as new bottles,
packaging film and fibres for making carpets and clothes.
The recycled plastic from just 25 drinks bottles can be made into a warm fleece jacket!
