The document discusses bio-inspired design and provides examples of case studies where nature inspired technological innovations that reduced drag. It notes that shark-inspired designs reduced drag by 1-3%, whale-inspired designs by 15%, and that studying unusual natural shapes like those found in snakes, geckos, and the condor's wing could have led to valuable innovations if explored earlier. The document advocates studying unusual natural forms to understand their functional purposes and apply those lessons to technology design.

before” (by a human or a non human)

3. Outline
• Famous Case Studies:
• Sharklets (1-3%)
• Whales (15%)
• Snakes (0%)
• Geckos (0%)
• Functional orthotics (0%)
• Expensive evolutionary shapes
• “Wierd” shapes Why

6. If you had paid attention the the condor wing 10 years ago,
you would be a millionaire by now.

New shape, 15% less drag.

8. Used by whales since the last ice age.

Whenever you find a weird, shape, (and concave feet are
wierd) you should ask yourself why five times
