Solar and Kid Power May 17, 2007
People eat to get their energy. The energy in the food is from
the sun.
Solar power can be used to make electricity to run motors, too.
The electrical energy can be saved up in a capacitor
and used to run a car later.
Kid power can be used to generate electricity by turning a motor that
acts as a generator.
If the kid energy is saved in a capacitor
then it can be used to run a car.
