TL 8 habitat

[rancke]

Assuming a population is living in a sealed habitat (orbital or on planetary surface with conditions that require isolation from the outside) and that they produce all their own food through hydroponics and carniculture. General TL is 8, but power a life support technology is one level advanced.

What sort of cubage would be required?

I highly recommend the book High Frontier by G.K O'Neil.

It has answers to lots of these questions for TL7.

Which rules yould you use?

In MT there are more or less clear rules for it, counting as life support (of course, being an inmovile place, inertial compensors may be foresaken, and, if on planet, grav plates probably too...)

Any that are plausible.

Sounds like the ones to use, then.

Note that I'm totally hoping to mooch off someone else's work here. My interests lie in different areas, so I'm hoping someone with more knowledge and interest in the subject could help me out.

... as a NASA Report, it belongs to the American people (sorry for the confusion).

[It took me some time to locate the exact source, the table is just a GIF that I keep around for quick and dirty reference.]

I think you're within fair use, atpollard, but can you include a reference for that page?

 

[DangerousThing]

You could do a search on archologies. The idea is a city in a building which takes up less ground space and less resources than a traditional city.

Not quite. It needs to be properly attributed to source as you're requesting, as I understand it.

atpollard: edit your post to include copyright and source information

 

[BytePro]

Its good form to attribute others' work ... and a good idea as a requirement for forum posts. It's also a good idea when a Moderator requests it, of course.

U.S. fair use has no requirement for attribution. Fair use is only determinable by a court of law - there are no other definitive sources - copyright law only sets up guidelines.

I'm trying to figure out the two columns "Surface area required" and "Projected area". They're different. But, you would think they would be the same. I think. What's going on there?

Here is the orginal document. It was part of a contest.

Surface Area required is the total square meters of floor area ... say I want 3000 sq m of office space. But the office building that I build is 3 levels tall, so I only need a 1000 sq meter lot of land (projected area) to build a 3000 sq meter office building (surface area required).

If you needed 3000 sq m of office space, you'd actually need 4 levels... because you're going to lose some of the 1000 per floor to vertical access...

Ahhhhhhh! That makes sense. Thank you.

You might also Google "Biosphere 2" since this is an actual attempt at what you want to model.

... and 1 parking space per 25 square meters of office space, and the required landscape buffers and the grand oak tree that needs to be protected and the required 10-20% green space, and the handicapped access route and the public restrooms and the employee restrooms and the water chillers and space lost to the 'architectural character' of the building ... :rofl:

But that is all just a little more detailed than the back-of-the-envelope calculations being proposed here.
