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
Construction costs
Maintenance costs
Time costs (e.g., how long does it take?)
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.
