today germany produces one third of its entire energy using solar and wind. so lets explore
how the solar fan works. this is the solar propeller and this is a small toy motor and
now you affix this plastic fan to the axle of the motor. there are two leads coming out
of this toy motor. these are attached to two screws and the motor is mounted on a wooden
stand. the propeller must rotate freely. this is the solar panel. this is the underside
of the solar panel from where the two leads are coming out and are attached to two crocodile
clips. affix these crocodile clips to the two screws and place this entire assembly
out in the sun. as the sun will fall on solar panel, the electricity will be produced and
the fan would rotate. if you cover the solar panel with your hand, the fan stops. this
is an amazing piece of green energy which children would love to play with. here you
can see two girls having fun playing with this solar fan, shutting it off and making
it go once again.
