I came to the farm to see how things grow And I learned some things I didn't know Plants can grow high Plants can grow low Some grow above the ground Some grow below

nanoBuilding concepts &
requirements
Research motivation
building industry produces lots of waste consumes lots of resources is not very effective
adequate housing not affordable for
1.6 billion peopleNT potentials
Research goals
design top-down NT based production concepts
further explore relevant NT areas nanorobotics bioengineering nanomaterials (Carbon Nano Mesh)
formulate requirements for the NT bottom-up research & start cooperation
nanoBuilding concept How things growBy multiplication of basic elements
bricks, cells, molecules,...using a plan that is either
extrinsic (building plans), intrinsic (instructions contained in
DNA), or combined (bonsai)
forming functional parts in their final size (a house) in growing size and functionality
nanoBuilding concept Growing facilitiesCommon practice of construction is
by sequential multiplication and composition of a variety of macro-level building
elements, produced by traditional ways of material
treatmentour goal: to mimic the natural way
using nano-level building elements
nanoBuilding concept Growing facilitiesExtrinsic plan
nanotechnology devices to produce building material at nano scale on site
phisics & chemistry lawsIntrinsic & combined plan
bionanotechnology / synthetic biology to program living particles to grow systems at the higher level
biological laws
NanotechnologyThe study of the control of matter
on an atomic and molecular scaleNanometer : meter = marble :
EarthA prooven method for growing
things - nature does it successfuly for billions of years
myosin, a bio-robot

Nanotechnology
NanomaterialsMolecular self-assembly (incl. DNA
nanotechnology), cause single-molecule components to automatically arrange themselves into some useful conformation
Programmable matter

Nanotechnology
Nanorobots (1 way to go): use of minuscule objects from DNA (TU München)
Nanotechnology in ConstructionMaterial refinment (e.g. 3-6x
higher strenght of conrete using nano-silica, self-cleaning & antifogging using TiO2)
New materials with better properties – carbon nanotubes (CNT), 100x strength of steel
nanoBuilding conceptThe process
1. 3D solid modeling2. 4D modeling (slicing &
sequencing)3. site preparation4. building & control5. functional testing
nanoBuilding conceptThe process
1. 3D solid modeling define detailed solid geometry define parts of the model (3D
areas), with specific material properties (strength, friction, conductivity, to form utility systems like water system, sewer system, electrical instalations, communication system etc.)
nanoBuilding conceptThe process
2. 4D modeling defining supportive structures where
necessary (for any vertical holes) slicing according to the thickness of
the nano layers sequencing – defining the sequence
and the default time for each slice
nanoBuilding conceptThe process
3. site preparation excavation to level 0 of the building setup building equipment – the
projector
nanoBuilding conceptThe process
4. building & control planting of “seed” nanoroborts onto
the ground plan self-replication of nanorobots
throughout the slice creating carbon nano mesh (CNM)
slice repeating the process slice by slice
nanoBuilding concept Summarized1. Use nanorobots, able to2. self-replicate, and3. build CNM using C from CO2 in the
air 4. with desired characteristics5. using light as a source6. for energy, and7. instructions (wavelenghts)
input: 4D model
Specific wavelengthstransmit differentinstructions to nanorobots:
- self-replicate- build CNM with specific characteristics

Instruction:- replicate
Instruction:- replicate
Instruction:- build CNM slicewith high bearingstength
Instruction:- build CNM slicewith high bearingstength
Instruction:- build pipe wall CNM with lowfriction
All utilities arebuilt-in (pipes,shafts, wires,...)
Supporting structure- temporary CNMmaterial to be decomposedafter window beamis built
The building is risingslice by slice...
nanoBuildingRequirementsNanorobots powered by light, able torecognize different wavelengths and
compiling them into instructionscompose CNM with required
characteristics (strength, conductivity) using C from CO2 from the airable to self-replicate
nanoBuildingThe future
Conclusion
I belive the question is not if (bio)nanotehnology can meet the defined requirements, but when.
The proof of concept exists!
