  • #42 - Mashael Yazdanie: "Doing the right things the right way" - how to holistically plan for sufficiency and renewable energy
    Apr 21 2025

    Mashael Yazdanie, Group Leader, Scientist and Lecturer at the Urban Energy Systems Lab at the Swiss Federal Institute of Materials Science & Technology (Empa) traces her journey across the renewable energies towards more holistic thinking around energy, sustainability, society and sufficiency. We cover her projects in both the global north and south, key concepts such as planetary boundaries, sufficiency, efficiency and doughnut economics as well as the need to learn, unlearn and relearn if we want to become more adaptive and resilience in the face of the climate crisis.

  • The NotebookLM Mini Series #3: Multi-tasking superheroes and going meta on AI (feat. Veljko Prodanovic)
    Apr 14 2025

    Welcome to this Mini-Series on The Grand Challengers Podcast! The topic of generative artificial intelligence (AI) has been in all our minds over the past few years and is gaining even more momentum with rapid advancements in text, audio and video. Google recently released NotebookLM, a powerful research-support AI that can generate not only summaries of sources that we feed it, but also entire podcast episodes. This Mini-Series will explore the power of NotebookLM, our live reactions to its outputs... and a deep dive into some of the topics that we have covered on the show. We feature previous guests, who are here to join in on the fun!

    Episode #3 delves into "Different perspectives on urban nature-based solutions" - Veljko Prodanovic (ep13) and I react to how NotebookLM produces a deep dive discussion on an opinion piece around human, ecological and AI perspectives of urban nature based solutions, this time guided by a focus prompt.
