This large generator powers the town. A generator based off the Canadian inventor Thane Hein’s machine Perepiteia, developed in 2003. The process begins by overloading the generator to get a current, which typically causes the wire coil to build up a large electromagnetic field. Usually, this kind of electromagnetic field creates an effect called the back electromotive force (back EMF) due to Lenz's law. The effect should repel the spinning magnets on the rotor, and slow them down until the motor stops completely, in accordance with the law of conservation. However, instead of stopping, the rotor accelerates - i.e. the magnetic friction did not repel the magnets and wire coil. The steel rotor and driveshaft had conducted the magnetic resistance away from the coil and back into the electric motor. In effect, the back EMF was boosting the magnetic fields used by the motor to generate electrical energy and cause acceleration. The faster the motor accelerated, the stronger the electromagnetic field it would create on the wire coil, which in turn would make the motor go even faster. The two massive motors operate of this principle. When the motors occasionally break down Leah get's em back online. They require only a small amount of gasoline to start.
