The Genius Device That Rocked F1 | An Interview With Its Inventor

Video Description

It was called the J-Damper, a mysterious device at the heart of the biggest spy scandal in Formula 1 history. For years, its true nature was a closely guarded secret, giving one team a massive advantage while rival engineers with the stolen plans were left baffled. In this exclusive interview, we sit down with the inventor himself, Professor Malcolm Smith of the University of Cambridge, to hear the incredible true story of the inerter. He reveals how a principle from electrical engineering allowed him to correct a 70-year-old flaw in mechanical theory, leading him to build the first prototype out of a child's Meccano set. Join us as we uncover: ► The chance phone call that pulled a university professor into the high-stakes world of F1. ► How McLaren secretly developed and used the "J-Damper" to win races. ► The full story behind the 2007 "Spygate" scandal and how rival team Renault fundamentally misunderstood the device. ► Why a technology considered "genius" was eventually banned from the sport. ► The future of the inerter in earthquake-proofing buildings, high-speed trains, and beyond. This is a story of pure innovation, industrial espionage, and a humble invention that rocked the billion-dollar world of motorsport. 🔔 SUBSCRIBE for more stories from the world of science and engineering! @Prof_Gio CHAPTERS / TIMESTAMPS: [00:00] Intro: The F1 Spy Scandal & The Mystery Device [01:57] Meet the Inventor: Professor Malcolm Smith [03:35] How a Chance Phone Call Started It All (Williams F1) [05:22] What are Active Suspensions?
