In this episode he explains how his team is using nanotechnology to remove toxic metals in water with brewed tea leaves and soaking up oil spills using a special sponge he invented, and many more ways he is leveraging nature's chemistry and nanotechnology to help solve global problems. ## Actions - request_transcript: `POST https://stenobird.com/v1/public/podcasts/nanoscape-exploring-the-frontiers-ahead-6988860/episodes/nanoscale-solutions-to-gigaton-problem-exploring-sustainability-with-vinayak-dravid/transcription-requests` — Idempotently request low-priority transcript generation for this episode. - read_markdown: `GET https://stenobird.com/podcast/nanoscape-exploring-the-frontiers-ahead-6988860/nanoscale-solutions-to-gigaton-problem-exploring-sustainability-with-vinayak-dravid.md` — Read the agent-friendly Markdown representation of this episode resource.
