Episode 462 - Fish helping make smart materials and renewable tech

December 20, 2021

What can fish scales teach us about the next generation of smart materials. Why is 'scale armor' often found in video games and on fish so strong? What is special about fish scales that can help us make a new generation of smart materials for clothing and structures? What do 35 million year old fish trapped in mud have to do with wind turbines and batteries? Renewable tech relies on Rare earth metals, so where do we find them? Studying fossilized fish can help us find more sources of rare earth metals to build more renewable tech.
