Electric Lighting

The earliest form of illumination was Fire, our ancestors relied on it to paint murals in caves and light their path. With the discovery of kerosene refined from petroleum, the oil lamp was born. After 8000 failed attempts, Thomas Edison invented the filament light bulb, the incandescent light bulb changed mankind, it spurred the development of electrical infrastructure. In the late 19th century, Edison championed direct current (DC) as the future of electricity, claiming it would outperform Tesla’s alternating current (AC). This rivalry between the two inventors intensified—until Nikola Tesla’s breakthrough: the high-power AC induction motor. This innovation showcased AC’s superior efficiency in long-distance, high-voltage transmission, solving the limitations that once prevented machines from utilizing AC power. Had AC not triumphed in this historic "War of the Currents," the world might still be relying on DC’s inefficient power grids, leading to skyrocketing energy waste and far worse pollution. The story of light and electricity is still unfolding—what other hidden tales await discovery?
