... from another new book I'm writing "Technologically progressive" ...

Modularity and interoperability would be the success key of any new mass-distributed mean of manufacturing, construction and transport.

While the materials exist, the issue is within the design logic. Most of raw parts are built in different measures to fit a design, after transformation, or custom-built, and therefore "non inter-operable".

For instance, in the case of frames, the design logic could change if we start thinking of a smaller "standard size" "interoperable" component, and of design logic of the system whereas the "design" consists on assembling the base blocks in the optimal configuration to obtain absolute oustanding performance, "without" altering the base block.

Now an air carrier can be recycled into enough modules to build two thousand homes or two thousand cars, at end of operational life, generating "positive income" at disposal, instead than the additional liability of spending more bucks to sink it in the middle of the pacific.

We have forgotten the most important phase in engineering, or we have not learned the most powerful force in nature and evolution: "disposal" and "reutilization".

We have also forgotten another critical item: "strategic reserves". Nature has its own, somewhere, of anything needed in its cycles. We do not, and we rely on industries that may not exist at the time we may need them.

Probably 90% of any structure human made can be reduced to interoperable triangles, a modest contibute from Geometry, to the miopic boxy car designers and box home builders, that can not see the round curves of the Universe.
