What machines can assemble structures?
Biological
- Examples:
- Environmental Operating Conditions:
- Energy Requirements:
- Capabilities
- Other Features or Problems:
Chemical
- Examples:
- Environmental Operating Conditions: (fluid, air, other?)
- Energy Requirements:
- Capabilities
- Other Features or Problems:
Mechanical
- Examples:
- Environmental Operating Conditions:
- Energy Requirements:
- Capabilities
- Other Features or Problems:
Other?
- Multisubstrate "cells"?
How can machines be controlled or programmed to produce structures in space and time?
Extrinsic
- Light (visible, 500nm; x-ray, 0.5nm)
- Sound
- Sensors?
- Other
Intrinsic
- DNA
- Digital Memory
- Machine-machine communication
- Amorphous Computing
How could the machines get energy and materials?
Exogenous Supply
- Liquid fuel (e.g., diesel)
- Sugar
- Other
Self-Acquiring
- Carbon fixation
- 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
- Carbon material density: 1400 kg/m3 => for 1m3 material 6.7*106m3 of air are needed.
- With air speed or 1m/s → 78 days needed for 1m of CNM; what about diffusion due to local reduction in partial pressure of CO2?
- Photosynthesis
- Other
When would it make sense to do this? E.g., what are the costs of building a house for a family of four?
Material costs
Transportation costs
Assembly costs
How would all of the above work together as an integrated process / system?
Below lies the research question sandbox
How could nanorobots fix CO2 → C + O2?
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.
