For kbd512 re #400
You nailed a century post!
This one is just to let you know your guidance was received and it is appreciated.
The near term looks promising. We can use a size specification for the habitats. Don't worry about height at this point. We need width and depth.
I'm guess at 15 meters wide and 30 meters deep. If that is good for you please let us know.
Calculations depend upon those firm numbers.
Also ... Please note that the calculations lead in the direction of 360 plots which can be distributed among 250 families. The remaining 110 can be used for retail businesses and small manufacturing activities. That might turn out to be close to the ratio seen in small towns around the world. I have only a sense of what the ratio actually might be. I've never thought about it before. The advantage of the 360 plot target is that the address of the location on the ring is a natural consequence of the decision.
You may (probably do) recall that the layout of Washington was the work of:
A Brief History of Pierre L'Enfant and Washington, D.C.Yes, the architect and engineer who laid out Washington, D.C. was a Frenchman named Pierre Charles L'Enfant (1754–1825). Appointed by George Washington in 1791, L'Enfant designed the capital with a baroque-style layout, featuring wide, diagonal avenues, grand radial vistas, and spaces for public monuments that still define the city today.
Your ring concept seems to me to have potential as a precedent setting concept. Your ideas about materials will secure a slightly different place in history, but no less significant.
Please spend a few minutes thinking about the 110 vacancies we've just opened up.

kbd512 Items that we know with many blanks still yet to determine overall volume needed
Developing anything on Mars with incomplete information is a project doomed to fail.
KBD512's only spec is as follows.
The 4 crew sleeping quarters is a volume of 145m cubic meters but what is missing?
Simple math: 1000 crew / 4 only gives a volume that is incomplete at 36,250cubic meters.
Here is some of the missing that changes that numbers as doors are required to exit or enter through, Whether these are pressurized doors, Hallways on either side, how adjacent quarters are placed next to each other as a curve leaves the walls at angles to the center of the shape, Are there going to personal hygiene within each quarters or are they combined as a central galley/ kitchen, food stores for dries or canned, freezer refrigeration, Mess table area for crew to eat area.
Quarters need ventilation, heating humidity control, linen areas for doing laundry and drying, how about exercise area and equipment, ect...
Without numbers or lights, outlets for individual occupants are further not specified items which are required.
Then there is the totals for all life support items to which include volumes needed to build as well.
power requirements beyond 10kw for 2 crew on the surface is for 1,000 will be 5 Meg watt
waste management A 4-person crew can generate up to 2,500 kg of waste in a one-year mission. A 3-year, 8-person crew is projected to generate roughly 12,600 kg of inorganic waste alone.
air scrubbing and replenishment
medical care, surgery, recovery Area: 23-28 sq meters per crew patient bed for monitoring, leave space for all side of bed for a minimum to support 50 crew
galley/kitchen, refrigeration/ freezing, dry food storage
greenhouse which is volume for 1,000 need per single person is 2m x 4m x5m = 40 cubic meter x 1,000 = 40,000 cubic m volume
power still needs calculations for LED
