What if a 1973 Opel with a stock engine outperforms a cutting-edge hydrogen fuel cell car? In this podcast, we dive into the physics of energy efficiency — exploring how a humble GM/Shell vehicle achieved 376 mpg through continuous waste heat recovery and steam implosion, while Toyota's Mirai relies on regenerative braking that only kicks in when you stop. We break down why recovering heat you were going to throw away anyway might be the most underrated idea in automotive engineering — and what it means for the future of clean mobility.
