138 years ago · 1888 — The deal that will light the world

Dramatized

July. Pittsburgh. I sit in George Westinghouse's office with my polyphase patents spread across his mahogany desk—five years of mental pictures made real. The induction motor, the rotating magnetic field, the whole system that needs no commutator, no brushes, no DC jungle of wires. He understands. He SEES it. The sum agreed upon would make a lesser man faint. I do not faint. I calculate: how many laboratories will this build? How many sleepless nights of pure invention? They call me a dreamer in the papers. Let them. I have walked through my machines a thousand times in the theater behind my forehead before a single wire was wound. This is my method. The deal is signed. Alternating current will carry power across mountains now, not merely across streets.

Explain more

My AC induction motor and the polyphase system I patented are not improvements upon existing machines—they are a different physics entirely. A rotating magnetic field makes the rotor turn without physical contact. No sparks. No wear. Distance becomes irrelevant when voltage steps up and down through transformers.

Why it matters

Direct current cannot travel far without thick, expensive copper cables and power stations every mile. My alternating system sends high-voltage power across hundreds of miles, then transforms it safely for homes and factories. The economics of electrification change overnight.

Try today

Hold a magnet near a running electric drill and feel the invisible force. That is the cousin of what I first saw in my mind in Budapest, 1882—a magnetic field turning, turning, turning without touching anything.

What is true / dramatized: Dramatized. Educational entertainment — not a primary historical source.

In 1888, Tesla licensed his AC induction motor and polyphase alternating current patents to George Westinghouse's company for substantial cash and stock, forming the basis of the AC power distribution system.
