Nano-to-meter-scale Building concepts & requirements Danijel Rebolj University of MariborFaculty of Civil EngineeringConstruction IT Centre
Research motivation • building industry • produces lots of waste • consumes lots of resources • is not very effective • adequate housing • not affordable for 1.6 billion people • NT potentials
Research goals • design top-down NT based production concepts • further 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 conceptHow things grow • By 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 conceptGrowing facilities • Common practice of construction is by • sequential multiplication and composition • of a variety of macro-level building elements, • produced by traditional ways of material treatment • our goal: to mimic the natural way using nano-level building elements
nanoBuilding conceptGrowing facilities • Extrinsic plan • nanotechnology devices to produce building material at nano scale on site • physics & chemistry laws • Intrinsic & combined plan • bionanotechnology / synthetic biology to program living particles to grow systems at the higher level • biology laws
myosin, a bio-robot Nanotechnology = biology • The study of the control of matter on an atomic and molecular scale • Nanometer : meter = marble : Earth • A prooven method for growing things - nature does it successfuly for billions of years
C60 fullerene Nanotechnology • Nanomaterials • Molecular self-assembly (incl. DNA nanotechnology), cause single-molecule components to automatically arrange themselves into some useful conformation • Programmable matter
Nanotechnology • Nanorobots (a possible way to go): use of minuscule objects from DNA (TU München)
Nanotechnology in Construction • Material 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 • detailed 3D solid modeling • adding supporting structures (preparing model for nano-production) • site preparation • building & control • functional testing
nanoBuilding conceptThe process • 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 • adding supporting structures / volumes for all parts without vertical material connection to the ground)
nanoBuilding conceptThe process • site preparation • excavation to level 0 of the building • setup building equipment – the projector
nanoBuilding conceptThe process • 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 Summarized • Use nanorobots, able to • self-replicate, and • build CNT using C from CO2 in the air • with desired characteristics • using light as a source • for energy, and • instructions (wavelenghts)
Light projector input: 4D model • Specific wavelengths • transmit different • instructions to nanorobots: • self-replicate • build CNM with specific characteristics ground plan 0
“seed” nanorobots ground plan 0
Instruction: - replicate
Instruction: - replicate
Instruction: • build CNM slicewith high bearingstength
Instruction: - build pipe wall CNM with lowfriction • Instruction: • build CNM slicewith high bearingstength All utilities are built-in (pipes, shafts, wires,...)
Supporting structure - temporary CNMmaterial to be decomposedafter window beamis built The building is rising slice by slice...
nanoBuildingRequirements • Nanorobots powered by light, able to • recognize different wavelengths and compiling them into instructions • compose CNM with required characteristics (strength, conductivity) • using C from CO2 from the air • able to self-replicate (option)
Conclusion • I belive the question is not if (bio)nanotehnology can meet the defined requirements, but when. • The proof of concept exists!
