Learn from Nature

1. Dr PR Arun

2. • The Natural systems are
– Supremely energy efficient
– Pollution free
– 100% Waste recycling (Zero waste !)
– Aesthetically and spiritually stimulating
– Technologically supreme
• Photosynthesis ---
• Firefly vs. Lamps
• Eye vs. Cameras
• Brain vs. computers
• Nerves vs. Transmission wires …

5. Every plant produce thousands of Chemicals here. However it releases is only
Oxygen as emission !!! - Compare it with Our Chemical Factories !

6. • Power Generation
– Electric rays, torpedo rays ..
• Lighting
– Bio luminescence (Fireflies ..)
• Power transmission
– Transmission in biological system (in
Brain & Nervous system)

7. None of our present day Lighting systems can match the
efficiency of these fireflies. They almost completely transform
Chemical Energy into Light with zero wastage as heat !

8. There are no open ended systems in nature,
All are cyclical and self sufficient

9. Chameleon’s Colour changing mechanism
is still a mystery, we are trying hard to understand

10. This Morpho butterfly produce colour out of nothing !! The wings are
actually transparent without ant coloured pigments
Can we ever copy this ?!

11. • Physical Strength
– Muscles of grass hoppers
are super powerful
• Co-ordination
– Millipede leg
movements require a
super computer to
simulate
• Movement
– Snakes, geckos,

12. Millipede leg movements require a super computer to simulate!
But its primitive brain manage it too well !!

13. Movement of Snakes are super smooth.
Can we ever copy it on to our vehicles ?!!

14. If You can understand its feet
You can have a shoes that would defy gravity.
How about walking up on the walls and across the ceiling !!!
Staircases & Ladders would be History !

15. • Leeches can
preserve the
ingested blood
(without losing
the structural
integrity of the
blood cells) for up
to 18 months !
No Blood bank of ours can do this feat !!

16. • Navigation system
– Migratory birds, Slugs, Ants, Honey
bees …
• Colouring
– Flowers, Butterfly wings, …
• Air conditioning
– Termites, Bee hives, ….

17. • Cover ~3000 miles
• Southward (Aug- Sep)
• The length of these
journeys far exceeds
the lifetime of most
Monarchs
• Travel ~50km/ day

18. Probably we are fast progressing only in this field. We have produced
even more toxic substances than the nature has ever done
