What was the War of Currents? The fight that decided how the world would be electrified

Vintage boxing-poster scene of Tesla and Edison facing off in a ring to symbolize the war of the currents between AC and DC power.

In the 1880s, electricity had a problem: nobody had agreed what an electricity system should actually look like. Thomas Edison backed direct current. George Westinghouse built around alternating current. Nikola Tesla helped make AC dramatically more useful. The resulting War of Currents involved transformers, patents, business rivalry, public electrocutions, safety fears, and some fairly ugly propaganda. AC eventually became the backbone of the grid—but DC never actually disappeared.

Who was Rudolf Diesel? A vision beyond his time

Rudolf Diesel in a late 1800s workshop, viewed from behind, working on an early diesel engine surrounded by vintage tools and machinery.

Rudolf Diesel wasn’t just an inventor—he was a man with a bold, unconventional vision for the future of energy. Most people recognize his name from the diesel engine, but did you know his groundbreaking creation wasn’t designed to run on fossil fuels? In fact, Diesel’s original idea involved something much greener (and surprisingly edible). Dive into the story of the man, his mission, and his unexpected legacy.
