22. Electricity can be made using a very simple
generator like this . If we spin a magnet around
a coil of wire , electricity is made in the wire.
23. If we connect a light bulb to the wires that
come out of the generator this electricity will
light it up .

52. ITER
This is an
experimental reactor
which will be built to
achieve nuclear fusion
Researchers would
like to use this fusion
to produce big
quantities of energy
on Earth
coverage
solenoids
53. Fuel cell
Researchers are
working to replace
fossil fuel motors
The use of hydrogen
in a fuel cell would
be less polluting
But it needs hydrogen
