14. Penguin Feathers — Thermal Insulating Fabrics
Penguins thrive in extreme cold thanks to tightly packed feathers and a waterproof oil coating.
Scientists used this natural insulation pattern to develop:
- High-performance winter jackets
- Cold-water diving suits
- Thermal building materials
- Insulating blankets
These designs combine warmth, lightness, and water resistance—qualities perfected by nature.
