"[Science fiction is] nightmares and visions, always outlined by the barely possible."
- Gregory Benford

| Lunar Concrete | ||
| A building material using lunar dust or similar surface material as a main ingredient. |
One of the basic problems of creating orbital cities or environments is the necessity of dragging everything you need out of the "gravity well" of Earth. A well-known solution proposed by various science fiction authors is to use materials from places other than Earth, where the energy cost of acquisition is not as large.
| Tessier-Ashpool ascended to high orbit's archipelago to find the ecliptic sparsely marked with military stations and the first automated factories of the cartels. And here they began to build. Their combined wealth, initially, would barely have matched Ono-Sendai's outlay for a single process-module of that multinational's orbital semiconductor operation, but Marie-France demonstrated an unexpected entrepreneurial flare, establishing a highly profitable data haven serving the needs of less reputable sectors of the international banking community. This in turn generated links with the banks themselves, and with their clients. Ashpool borrowed heavily and the wall of lunar concrete that would be Freeside grew and curved, enclosing its creators. |

A concrete mixture is an interesting and natural choice. I don't think I've heard it mentioned elsewhere in science fiction; there may be an earlier reference in Heinlein.

'The world ... is drenched in unfamiliar information all the way to the horizon.'
'He saw one hiss by him as he rounded the corner, trailing a short whip antenna...'
'It may be organic damage. It may be permanent. Time'll tell, and only after you are off Substance D for a long while.'
It's the polite thing to do, and has been the polite thing to do for about four generations.
