3. Three routes to the manufacture of nanomachines: 1. Build proteins 2. Use the STM 3. Use chemistry

5. …and buckminsterfullerine

7. Interesting properties of buckytubes : As thermally conductive as diamond As electrically conductive as copper 100 times stronger than steel, 10 times stronger than carbon fibre. Hydrogen storage, bulletproof vests, nanomachines, and the Space Elevator…

8. The Space Elevator

13. A flock of Craig Reynolds’s boids encounters a cluster of pillars.

15. Marco Dorigo at the Free University in Brussels has solved network problems using colonies of artificial ants.

16. `Magnetic’ termite mounds, Australia

19. Genetic algorithms permit adaptive behaviour to emerge from simple rules.

20. Conclusion Dramatic changes are possible But some hard problems must be solved first, especially in flock intelligence.
