## Summary

Hosts Daniel and Forbode discuss three sustainability-focused technologies: a Carnegie Mellon University IoT model for vehicle emissions, Harvard University's shapeshifting recycled wool fabric, and the German Aerospace Center's hydrogen fuel cell aircraft project. The episode details how machine learning improves OBD inspection accuracy, how shape-memory fibers enable wrinkle-free clothing, and why hydrogen is preferred over batteries for regional aviation despite efficiency losses. Key figures include PhD student Prithvi Aquaria, Professor Scott Matthews, Professor Paul Fishbeck, Professor Kit Parker, and post-doc Lucas Sarah.
