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

Nano-to-meter-scale Building
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
conceptsfurther explore relevant NT areas
nanorobotics bioengineering and synthetic biology nanomaterials (3D Carbon Nano Tubes)
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
physics & chemistry lawsIntrinsic & combined plan
bionanotechnology / synthetic biology to program living particles to grow systems at the higher level
biology 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
= biology
NanotechnologyNanomaterialsMolecular self-assembly (incl. DNA
nanotechnology), cause single-molecule components to automatically arrange themselves into some useful conformation
Programmable matter
C60 fullerene
NanotechnologyNanorobots (a possible 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 process1. detailed 3D solid modeling2. adding supporting structures
(preparing model for nano-production)
3. site preparation4. building & control5. functional testing
nanoBuilding conceptThe process1. 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 process2. adding supporting structures /
volumes for all parts without vertical material connection to the ground)
nanoBuilding conceptThe process3. site preparation
excavation to level 0 of the building setup building equipment – the
projector
nanoBuilding conceptThe process4. building & control
planting of “seed” nanoroborts onto the ground plan
self-replication of nanorobots throughout the extent of the building layout
creating carbon nano materials continuously repeating the process
until the top of the building is reached
nanoBuilding concept Summarized1. Use nanorobots, able to2. self-replicate, and3. build CNT 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
Light projector
ground plan 0
ground plan 0
“seed” nanorobots
Instruction:- replicate
Instruction:- replicate
Instruction:- build CNM slicewith high bearingstength
Instruction:- build CNM slicewith high bearingstength
Instruction:- build pipe wall CNM with lowfrictionAll 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 (option)
nanoBuildingThe future
ConclusionI belive the question is not if
(bio)nanotehnology can meet the defined requirements, but when.
The proof of concept exists!
