Almost all batteries, even single-use batteries, are theoretically rechargeable. That's because the metals and other chemicals are still there in the battery. So chemically speaking, a dead battery is actually not that different from a fresh one. Then why do batteries die in the first place? And what should you do with them once they're spent? George Zaidan digs into the science of batteries. [Directed by Luisa Holanda, narrated by George Zaidan, music by Gabriel Maia]. After the talk, Sherrell reflects on the future of recycling batteries and the important role it plays is supporting sustainable energy. Hosted on Acast. See acast.com/privacy for more information.

Folge vom 25.07.2025Why AI is our ultimate test and greatest invitation | Tristan HarrisTechnologist Tristan Harris has an urgent question: What if the way we’re deploying the world’s most powerful technology — artificial intelligence — isn’t inevitable, but a choice? In this eye-opening talk, he calls on us to learn from the mistakes of social media’s catastrophic rollout and confront the predictable dangers of reckless AI development, offering a “narrow path” where power is matched with responsibility, foresight and wisdom. After the talk, Sherrell reflects on why it's wise to slow down AI's development and discuss about the organizations working to safeguard AI's impact. Hosted on Acast.
