I had the pleasure of meeting Saurabh Mangla on a day where I was hot, tired and just wanted a beer. But getting the story of his materials lab and how he's working to explore how cities use their materials more effectively, efficiently and in many ways, delightfully is a good reviver. We talk about Singapore, India and how material resources can be an excellent way for cities to demonstrate their Challenger mindset. ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/challenger-cities-6959558/episodes/challenger-cities-ep80-the-materials-of-cities-with-saurabh-mangla/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/challenger-cities-6959558/challenger-cities-ep80-the-materials-of-cities-with-saurabh-mangla.md` — Read the agent-friendly Markdown representation of this episode resource.
