The man who lit the modern world and died owing rent. Alternating current, the rotating field, the polyphase system everyone uses and almost no one credits. Edison got the statue. Tesla got the unit and the last laugh. Worn plainly, function before credit, the way he would have wanted it. For people who want function before credit. A Nikola Tesla graphic tee for engineers, physicists, science fans, and anyone who got out-credited and shrugged. AC current, the rotating field, the polyphase system everyone uses and almost nobody names. A gift for electrical engineers, students, makers, and the function-before-credit crowd.
