This document discusses various sustainable and innovative materials including those inspired by nature like spider silk, abalone, and lotus leaves. It covers materials that are strong yet lightweight, change properties based on stimuli, can exchange or generate energy, and are sourced from renewable and recycled sources. The goal is to highlight materials that can meet needs without compromising future generations' abilities.

49. Spider silk The strength of a biological material such as spider silk lies in the specific geometric configuration of structural proteins, which have small clusters of weak hydrogen bonds that work together to resist force and dissipate energy. The Massachusetts Institute of Technologys Civil and Environmental Engineering (CEE) department, in collaboration with SDSC researcher Ross Walker, found that this structure is as strong as steel, even though the "glue" of hydrogen bonds that hold spider silk together at the molecular level is 100 to 1,000 times weaker than steel's metallic bonds or Kevlar's covalent bonds
