Modelling and Enabling a Manufacturing and Construction Revolution

This site recently discussed the seeds of Manufacturing and construction revolution.

The seeds of the revolution are:
– Contour crafting (scaling up inkjet/rapid prototyping up to making buildings, cement jet) Use cement as the ink. Layer by layer additive construction. 200 times
faster than conventional methods. 5 times lower cost for construction.

– Inflatable electric cars. Flatship cars from a factory like Ikea furniture and could be as cheap as $2500 for an environmentally friendly car.

– Reel to reel production of electronics can be hundreds to thousands of times faster than current lithography factories for making computers and factories for making electronics, televisions, video monitors.

Other seeds are
– wafer scale self assembly of nanoscale components
– Nanotubes and more new materials (nanosteel able to withstand higher temperatures and retain strength)
– wood based fibers able to make paper and cardboard stronger than cast iron. Cheap and plentiful material that could be strong enough for many applications.

Making things 100 times faster than we do now would require a lot more planning to prevent many unintended problems. We need to take the best methods of today like Building Information Modelling and city planning and take those to the next level as well.

Modelling and Planning the Manufacturing and Construction Revolution

Once a computer model of a building has been created, it is possible to extract detailed plans of particular subsystems, such as cooling, water and electrical wiring

The Economist magazine talks about the shift for architects from 2-d blueprints to 3d databases. The amount of data and the variables that are modeled need to be increased. A denser data version of Second Life [virtual world modeling] needs to be made. Various proposed construction can be planned out to end of life.

Elaborate digital models for cities. Currently architecture and city planning are mostly 2-Dimensional professions.

Modeling to get better estimates, schedules and then simulate.

Building Information Management detail or greater fed into Second life virtual reality with many scenarios and at faster than real-time simulation modes.

There should also be various inexpensive real-time sensors tracking various aspects of safety and feeding models with updates on the current situation.

– Time and infrastructure health of surrounding systems and buildings relative to next maintenance task
– Actual emissions at and around the building site
– Traffic and people flow and usage patterns

More rapid and cheap construction could help address things like the California Dike problem.

Advanced City Planning
More detailed data, with more frequent updates at the city and larger scales. Various links on the subject are below.

Accelerating the Economy
Accelerating the economy while maintaining or improving safety will require coordination and effort. Just like being able to have trains move faster and with fewer delays requires planning, coordination and effort.

Looking at the “mundane possible speedups” [not using nanofactory level molecular nanotechnology or Artificial general intelligence] will also flesh out the requirements for MNT speeds.

Each of the levels of faster speed would require consideration.

10 times faster construction would mean – less time for various checks from weeks to days.

100 times faster means minutes for turnarounds or everything pre-checked and approved.

1000 times means all interested parties must have their issues pre-thought out for work in the pipeline up to one year in advance. A pre-planned city wide wiki of intersection projects. New software and new project planning may be required to enable each level.

Plans would be going into a queue for simulation, software-agent first pass comments and validations.

How modularized and disconnected can things safely be? The more compartimentalized things can be then the more simplicity and speed can be retained. There is value to higher safe development speeds.

20% growth – 1997-98 Internet time across the whole economy
If Robin Hanson is correct about the economics of the singularity, this would be the real long economic boom.
