Clay
Clay is one of the oldest materials humans have ever used, from early pottery to the walls of homes. In this episode, host Joe Hanson explores how this ancient material can inspire new solutions for an increasingly warming world. Brook Kennedy, Design Professor at Virginia Tech in the United States, explains how traditional technologies can offer valuable starting points for contemporary design. Inspired by passive cooling methods such as wind towers and water jars, he and his team are developing 3D-printed clay partitions that use evaporative cooling. Dr. Frank Reuter, Business Manager Cavipor® at BASF, presents a breathable clay-foam insulation material that can be injected into wall cavities in existing buildings without invasive retrofitting. Cavipor insulates against heat and cold, dampens noise, and is flame-retardant. For older homes in particular, it offers a way to improve comfort and energy efficiency while preserving the building’s original structure. Clay becomes a reminder that simple, familiar substances can still hold surprising potential when we look at them with fresh questions. In the next episode, we will discuss “Enzymes”.
