I saw a George Clooney movie called Tommorrowland and saw impossible buildings and vehicles on the screen. Like the theme of the movie I said why not?
Every epoch of man has been associated with the materials he has manipulated; stone age, bronze age, iron age...
Material science has brought us good and bad like nylon and plastic.
However an ultimate material is already part of us and that is carbon.
So strong is C70 it could support an elevator to orbit.
We have gone from assembling buckminster fullerines C60,c70 in nano amounts to micro gram and now gram amounts. The process involved arcing electricity between graphite electrodes through soot in a helium atmospere. We never thought we could mass produce the stongest material on Earth for things like bridges and buildings. Imagine making fullerines by the pound that quickly leads to tons. Imagine the archetecture, like permanent housing that could still be moved due to light weight. Imagine the airline industry and advanced aero dynamic aircraft and space ships. Strong unbreakble and light as a feather per inch.

I propose the Fullerine age. Recent advancements have allowed programable self assembly of this special carbon with protein folding and peptide cloning. Add these propriatary biological tricks to something like huge Russian artificial diamond making pressure chambers and we can scale up to construction sized modules.

PS this concept goes back to Buckminster Fuller so its been long in the making. Concrete will have its place but probably will become too expensive.
