It is the year of our Lord 1884. A young Serb named NIKOLA TESLA sets foot in New York with little but a letter of recommendation, four cents in his pocket, and visions of alternating current humming through the air.
The streets are lit by the direct current empire of THOMAS A. EDISON — a man who will not surrender his monopoly. He hires gunmen, newspaper hounds, and travelling carnies to slander the new current. He electrocutes animals on stage to prove AC will kill ye in your sleep.
Tesla rides west alone — but not for long. The Pittsburgh industrialist GEORGE WESTINGHOUSE hears tell of his patents and rolls his AC wagon out to meet you on the trail. Watch for him in every stage — when his wagon rolls in, shoot the Polyphase Crate off the back for full restore and a 6-second AC overdrive.
So Tesla took up a cowboy hat, a copper-coiled six-shooter, and rode out to wire the world.
Tesla's coil-gun draws on his Load Factor. Take a clean steady fight and his cannon will arc lightning chains across the plain. Let Edison's bandits land sudden spikes and his weapon shall downgrade — coil to pistol to revolver to spark to a flickering DC beam not fit to light a parlor.
Your Load Factor reached zero. Your splendid coil-cannon decayed step by step until you were firing the very direct current you came to dethrone.
In the real grid, this is what low load factor costs us: utilities must build expensive generators that sit idle most of the year, kept on standby for short demand peaks. A flat demand curve is the cheapest current of all.
You have unhorsed Edison and lit up the new century. The polyphase alternating current system Tesla and Westinghouse championed lit the Chicago World's Fair, harnessed Niagara, and now powers nearly every wall socket on Earth.
Edison's direct current wasn't useless — today it drives data centers, electric vehicles, undersea cables, and the very screen you're looking at. The truth, as always, was a polyphase one.
And the lesson Tesla rode with stays true: the smoother your demand curve, the higher your load factor, and the cheaper the wire.
