This is a picture of a generator stator that’s was delivered to a coal power plant in the North Carolina/South Carolina region. It took 20 days for the stator to travel from the port in Charleston to its destination. Two trucks moved it form the port to its future home. The trucks, end to end, combined to total 304 feet. Realizing that this portion of the generator is 304 feet, you get an idea of the overall generator’s size. Huge! And this is just for one unit. Most coal power plants have two, three or four units.

Something to consider when you flip that light switch.

What is a stator you ask? According to Wikipedia,

The stator is the stationary part of a rotor system, such as in an electric generator or electric motor
Depending on the configuration of a spinning electromotive device the stator may act as the field magnet, interacting with the armature to create motion, or it may act as the armature, receiving its influence from moving field coils on the rotor.
