Edison and Tesla's war for electricity

Show notes

This episode explores the fierce late-19th-century rivalry known as the War of the Currents, as Thomas Edison and Nikola Tesla promoted competing visions for the future of electrical power. Edison championed direct current, while Tesla developed an alternating-current system capable of transmitting electricity efficiently over much greater distances. The competition became increasingly intense as Edison sought to portray alternating current as dangerous, including demonstrations involving animal electrocutions and support for the electric chair.
Tesla eventually partnered with industrialist George Westinghouse, giving his technology the financial and industrial backing needed to compete. A major breakthrough came when the alternating-current system was selected for the Niagara Falls project, helping establish AC as the dominant method of electrical distribution. Despite their technological achievements, both inventors experienced significant personal and financial setbacks, with Edison losing control of his company and Tesla ultimately giving up substantial licensing royalties.
