Nature's Catalog

Evolution has spent hundreds of millions of years testing designs, and the ones that survived are now blueprints we can borrow:

• Lotus leaves: a bumpy waxy surface that water cannot wet, copied for self-cleaning coatings.
• Spider silk: stronger than steel by weight, yet spun from proteins and water.
• Termite mounds: passive cooling that needs no electricity.

The common thread: nature builds with renewable materials at ordinary temperatures, and never makes a poison it cannot recycle.
