Edison vs Tesla: The War of Currents, The Spark of Progress
Introduction
most retellings, it’s a duel. Edison, the tenacious inventor-businessman, defending his vision of Direct Current (DC). Tesla, the visionary outsider, promoting Alternating Current (AC). One rooted in control. The other in reach. But the 250th Anniversary Mural doesn’t depict this chapter of history as a fight to the finish. It frames it as a tension between two minds- each illuminating something larger than themselves: a spark that launched modern America into the age of electrical possibility. In this blog, we explore the mural’s portrayal of the War of Currents and how it represents not just technological rivalry, but philosophical divergence- two modes of thinking, both essential to progress. A Moment in Motion The Progress section of the mural places this scene just beyond the railroad’s expansion and just before the rise of aviation. It’s a midpoint- both literally and metaphorically- between grounded invention and unleashed imagination.
In the mural, Edison and Tesla do not face each other directly. Instead, they appear in adjacent panels, each surrounded by distinct visual motifs. Edison stands in a room of filaments, prototypes, and lab equipment. Behind him, a wall is cluttered with patent diagrams, wires coiled like thoughts. His expression is focused. His hands are busy. Tesla, by contrast, is rendered in a space of open energy. Lightning arcs from coils. He is framed not by objects, but by force. Behind him, a diagram of the Earth encircled by wave patterns, hinting at his dream of wireless global transmission. The mural refrains from choosing sides. Instead, it captures contrast- and in doing so, honors both.
The Philosophical Divide Direct Current, Edison’s preferred model, offered safety and control. It required infrastructure to be local, manageable, and standardized. In his mind, electricity was a service- something to be delivered reliably, regulated carefully, and built from tested models. Alternating Current, championed by Tesla and commercially backed by George Westinghouse, was riskier in perception but far more scalable. AC could travel longer distances, adapt to variable loads, and transform voltage across systems. It imagined a world far beyond what was currently possible. This divergence wasn’t just technical- it was psychological. Edison represents iteration: invention as refinement. Tesla represents vision: invention as revelation. The mural places these tensions side by side, not as rivals, but as modes- two minds building the scaffolding of the electrical age.
What Was at Stake At the height of the War of Currents in the late 1880s and early 1890s, the stakes were enormous. Cities were beginning to electrify. Businesses and governments were deciding which system to invest in. Propaganda flew in both directions- Edison’s team warning of AC’s dangers, Tesla’s supporters highlighting DC’s limits. The mural doesn’t rehash the marketing battles or show the infamous electrocutions staged to sway public opinion. Instead, it focuses on output: illuminated streets, glowing bulbs, industrial plants springing to life. It tells us what mattered most: that light spread. That cities were powered. That, despite friction, innovation advanced. Beyond the Currents: A Nation Awakens One of the mural’s most striking features is how it shows electricity moving outward from both men- not in one direction, but in branching flows.
From Edison’s lab, wires run into buildings and lampposts. From Tesla’s coils, arcs leap toward open space, suggesting future technologies not yet realized. And through both streams, the mural draws attention to the surrounding changes: public schools gaining nighttime lighting, factories expanding shifts, homes beginning to glow from within. Electricity, here, is not just about invention. It’s about impact. The mural uses this moment to remind us that progress is not made by consensus. It is made by contradiction that eventually converges- where differing visions force the system to evolve.
Why the Rivalry Still Resonates Edison and Tesla were not merely inventors. They were symbolic embodiments of competing American archetypes. Edison, the practical doer- rooted, empirical, commercial. Tesla, the intuitive dreamer- untethered, theoretical, idealistic. The mural does not declare a winner because progress never crowns one. It integrates. Edison’s DC still powers batteries and microgrids. Tesla’s AC remains the backbone of the electrical grid. This convergence is symbolized in the mural by a final image: two children holding sparklers, standing beneath an electric sign. One spark trails left. One trails right. Both illuminate the same night.
Why It Still Matters
The War of Currents teaches us that innovation doesn’t require agreement. It requires risk. Dissent. Differing visions that refuse to collapse into the lowest common denominator. Today’s innovations- AI, renewable energy, space exploration- will echo these same tensions. Practicality versus possibility. Profit versus principle. Safety versus scalability. The mural captures this not to dramatize the rivalry, but to honor the spark it released. That spark, born in disagreement, lit the world.
