How to create electricity?

"Chapter 1" How to create electricity?

	We know power stations create electricity but we don't know how to create electricity.
	There are many methods of generation electricity, but the fundamental methods are same. It is easy for you to understand,……you know bicycle.
	Of course.Why bicycle?
	I mean the light of bicycle.
	Oh,I've never changed that light! It doesn't have cells.
	It flashes by itself.The rotary motion of tire creates electricity to turn light,on.
	The rotary motion?
	When you press the button in the upper part of light system touches with the tire.
	So I fell the pedal is heavier than before.
	The motor is on the headlight. Of course when you electrify to the motor,it turns.
	You said "The tire turns when you electrify to it".
	I've got you."Electrification produces rotation", means"rotating motor produces electricity".
	That's right.Because the light rotates motor,you feel it heavier.
	I see. Rotating motor creates electricity is the fundamental method of power generation.
	The flashlight and the radio have that rotating system. Because if the disaster occurred,it would create electricity by itself.
	I see.What kind of power generation systems are there?
	Let's look at a variety of power station. Rotating motor creates electricity is the fundamental merhod of power generation.
