Ship Design - Deck plans

T4 FF&S has them:

TL	Type	Vol Td	Vol m³	Mass (T)	MW	Minimum Capacity		Aramis Td	Aramis Sugg. MCr
8	Va (Algal Vats)	7.14	100	50	0.01	25		7	2
9	Vb (Vats & Gardens)	14.29	200	75	0.02	30		14	5
10	Vc (Add small animals)	35.71	500	125	0.05	40		35	15
10	Vd (Add large animals)	107.14	1500	200	0.05	75		100	50

Oops, the volume specified is per person, with a minimum number of persons given in Minimum Capacity.
A minimum type V-b installation would be 200 m³ × 30 people = 6000 m³ ≈ 430 Dt.

Costs are in the errata at between MCr 0.1-1.5 per m³. So the minimum type V-b installation above would cost MCr 0.2 × 6000 m³ = MCr 1200...

A minimum type V-d (producing beef the natural way) would be 1500 m³/p × 75 p = 112500 m³ ≈ 8 kDt and cost 112500 m³ × MCr 1.5/m³ = MCr 168750 ≈ GCr 169. Feeding 75 people that is over 100 Dt and GCr 2 per person...

If we take the errata literally the mass would be 112500 m³ × 200 t/m³ = 22 500 000 tonnes.

I don't think this was quite though through, and even the errata needs errata...

I would supposed it's implied that the air would circulate throughout the ship, to maintain a consistent oxygen content.

Might be somewhat strenuous, if you have a minimum crew on a megafreighter, with all those cargo holds.

 

[AnotherDilbert]

If we correct the errata to be per person, not per m³, we get a minimal type V-b at 430 Dt, 2250 tonnes, and MCr 6.

At 14 Dt per person it wouldn't be impossible, but not very practical. Cost and power would be inconsequential.

How else are we supposed to space the Babearlon 5 bear merchandise?

The bear excretes waste in the woods, where the grassphault and trees sop up nutrients liberated by the cultured microbiotia...
At least in type V.d LTLS

No spacer, you don't waste air to push your poo out the airlock, get the broom out of the locker and do it yourself. Yeesh, air ain't free in space. Damn noobs..oooo look air lock go whoosh.

I remember a Trek con where James Doohan was reminiscing about some questions he got at other conventions as Scotty. When he was asked why there were no toilets in the first edition of the Enterprise blueprints his reply was "That's what phasers are for!"

"That's what phasers are for!"

Wait, the food processors weren't two way?

It's what keeps the crew and passengers alive.

I suspect in previous editions it's take for granted, and it's still rather vague in the MongoVerse, but going by suffocation rules, you could turn it off and live off the fumes for a while, I think six months?

I'd pack a stillsuit, though.

1 cubic meter of air has a useful O2 for about 4 hours for one person.
The CO2 will become the problem at about half that.
1 Td is 13.5 kl,,, so about 26 hours without scrubbers, 2 days with.
Either way, at the end comes anoxic loss of consciousness...
Note that the space available as air is about half of staterooms, bridge, and shop tonnage, 1/4 of drives, and most of unused cargo,

So a stateroom is about 4 days with the CO2 scrubbers on batteries....

Not to mention heat and humidity control of all the spaces in question, and hopefully industrial strength tainted atmo/biofilters.

I’d say we are paying a premium for miniaturized no hassle ultra reliable life support systems. Don’t like the price? Pay for it in tonnage and dedicated engineer crewmen…
