Biological, chemical, mechanical, biomechanical?
Multifunctional "cells" (chains of nanorobots, organelles)
- light sensors
- CO2 "catchers"
- CO2 → C + O2 fixation
- Higher-order material assembly (e.g., carbon nanomeshes, wood, composite materials, et cetera)
How could a nanorobot decode light wavelengths?
What would be minimum wavelengths?
- visible light: ~500nm
- X-rays: ~0.5nm
What sensors would they need?
Getting C from CO2
How could nanorobots fix CO2 → C + O2?
How much air is necessary for a m3 CNM?
- CO2 quantity in air: 0,00076626 kg/m3 or approx. 1g/m3
- C quantity air: 0,0002088 kg/m3 or approx. 0.2 g/m3
- CNM density: 1400 kg/m3 => for 1m3 CNM 6.7*106m3 of air are needed
- with air speed 1m/s → 78 days needed for 1m of CNM
How fast could nanorobots catch CO2 molecules from a normal atmosphere?
What energy is necessary to decompose a CO2 molecule?
What flux has to be transfered from the projector?
How could a nanorobot build CNM?
How exactly do plants grow?
What self-replication methods could be used?
What is the minimum frequency of self-replication to be effective?
- 1 nanorobot size ≈ 100 nm → area = 104 nm2
- 1m2 = 1014 nanorobots → 45 replication cycles
- 20' per cycle = 15 hours to cover 1m2 starting with 1 nanorobot
Bacteria can make reproduction look easy; can they also be instructed via specific light wavelengths?
- Yes.
