FYI, I'm currently writing up a Design Document, and organising the Dev Team, ergo the quietness.

[Seamas]

I was *so* close to wetting myself until I saw there was no download link.  Well, god speed to you noble programmer and may this brainchild take shape soon!

[Warning: Gloat]

So, I had to work out a way to work out how much "Air" is needed on a ship.

On a basis that a person consumed 11,000 Air a day...

ShipM = Ship Length in Meters
ConS = Consumption Rate (11,000/day)
ShipS = Ship Gas Storage size

ShipS = ShipM * ConS

25 * 11,000

So first, I had to figure out how to make it last for about 4-8 months, depending on ship size, but making sure that a small ship didn't last for 8 months, and a Large ship didn't last for 5 days (On full crew capacity).

(Largest "Large Class" Ship = 315, takes a crew of 60)
((ShipM)315 / (Crew)60) / 11,000 = 5.25 Days

5.25 days. Seriously? Now I need to find a decent multiplier for that.

5.25 * 12 = 63 Days

Still not good enough. 2 months.

Let's say I want it to last for 6 mean months (3 "30 days" and 3 "31 days")

days / Modifier = ConS
244 / X = 5.25
5.25 * X = 244

I had to figure out X.

Came out as 47... Nearly 42. Heh. 47 was a bit much for a multiplier, so I knocked it down to 4.7.

(Multiplier * ShipM) / ConS = Days
(4.7 * 250) / ((250 / 50 / 11,000) = 258.81
1175 / 4.54 = 258.81 Days

(Multiplier * ShipM) / (ShipM / Crew / ConS) = Air Lasts For
(4.7 * 12) / ((12 / 2 / 11,000) = ConS)
56.4 / 0.54 = 104.4

Capital Class ships have Biodecks, meaning they're self-sufficient.


Now, just for fun... *If* a Capital Class's Biodeck was burnt to a cinder, and there was one crew member left... How long would he last?

(Multiplier * ShipM) / (ShipM / Crew / ConS) = Air Lasts For
(4.7 * 700) / (700 / 1 / 11,000) = X

Spoiler (click to show/hide)

3290 / 0.06 = 54833.33 Days


That's 150.22 years. Wow.

[Neyvn]

Don't most Scifi Shows say that they recycle the air???

In 5 thousand years, I THINK we'll figure out how to recycle air.

Or how to continue decomposing. Whichever works best.

[Neyvn]

Well all that up there, is a big old number for using Oneshot Airtanks...

[nuker w]

Posting to watch, woohoo.

[head]

Well there is two ways to recycle air.


A: Biodecks feeding the plants the CO2 discarded from humans (But how much would you need? per plant)
B: Using sexy awesome techongly to turn CO2 into Oxygen

[Siquo]

Watching for awesomeness.

B: Using sexy awesome techongly to turn CO2 into Oxygen

Just cut out the C and use it to make diamonds or something. What remains is pure refreshing oxygen.

You could call it "Diamond Air" and sell it in cans.

About this "air" thing, where does the "11000" come from ?

Other than that i have a few comments :
- we don't consume "air", we consume oxygen.
- your crew will die from CO2 poisoning before running out of oxygen.
- if you have CO2 scrubbers, they will lose performance over time due to O2 rarefaction and will die before the O2 levels reach 0.
- if you use O2 tanks, you can store oxygen at up to 700 bar with our current technology (i think).
- a human being consumes about 500 liters of O2 per day (about 700g).
- 1 cubic meter of O2 @ 700 bar = 700 000  liters @ 1 bar = enough O2 for one human for 1400 days (weights almost a metric ton though).

Edit : i wrote this assuming that you're not using O2 tanks and are only relying on the same ambient air for the whole trip.

[PTTG??]

I approve of this project.

i got something better:

That's a good way to get (slightly) high, but you'll be wanting some other gasses to decrease the oxygen content in the on board atmosphere.

But then again apparantly space suits are supposed to be pure oxygen affairs. Maybe it's alright to get wasted if you're an astronaut?
