Nikola Tesla delivers a lecture describing the equipment which will allow efficient generation and use of alternating currents to transmit electric power over long distances.

Nikola Tesla was a brilliant inventor, electrical engineer, and futurist best known for his groundbreaking work in alternating current (AC) electricity. Born in 1856 in what is now Croatia, Tesla immigrated to the U.S. and briefly worked with Thomas Edison before striking out on his own. His contributions were foundational—he developed the AC induction motor and transformer, technologies that made long-distance power transmission possible. Tesla also experimented with radio waves before Marconi, envisioned wireless energy transfer, and proposed early concepts for radar and even smartphones. Despite his genius, he struggled with business, often being outmaneuvered by more commercially savvy contemporaries. Still, his legacy lives on, not just in the Tesla coil or the electric car company bearing his name, but in how we use electricity every day.
