Melissa and Jam explain how evaporating water can cool a building and why the same approach works much better in dry climates than humid ones. They connect swamp coolers to older cooling techniques and examine newer ideas, including ice-based systems intended to reduce pressure on electricity grids.

NASA aerospace engineer Nate Olson joins Taylor Sparks and Andrew Falkowski to discuss the materials and engineering behind spacecraft thermal protection. Topics include blunt-body designs, Apollo’s ablative heat shield, the Artemis I heat-shield anomaly and future protection systems. The scientific discussion is part of the Materialism materials-science series.

Melissa and Jam unpack the chemistry inside an air conditioner. They explain how refrigerants, pressure changes and transitions between liquid and gas move heat out of a room, why the outdoor unit releases warmth, and what frozen coils reveal about the cooling process.
