The Stateroom revisited...

[HG_B]

I have slightly different rules in this area.

Staterooms = 6 tons & double occupancy

3 tons of actual stateroom @ MCr.04/ton
1 ton for passageways @ MCr.04/ton
1 ton for Common spaces @ MCr.04/ton
1 ton LS equip + water/air/food @ MCr. 0.3 (for the equip)

Thus one can add space as needed for more luxury without adding more LS at a cost of MCr. .04/ton

Or, one can add more LS equip to have higher density of passengers (within reason of course).

I calculated a while back that food for 1 month for 1 person using TV dinner-like trays of 1 inch by 12 inch by 12 inch would only have to be a 2 foot square cube (4 stacks of 24 trays = 96 meals for breakfast, lunch, and dinner for 32 days) that could fit under someone's bunk and probably just a smallish-sized microwave contraption on the galley counter to cook them. Maybe 200 pounds, including cooking device.

All in-stock at the local StarshipMart.

By the time Tech Level 15 rolls around, the recyclers for both air and water/waste would probably be pretty compact and efficient. Maybe 100 pounds or 200 pounds at the most. Even so, 8 pounds per gallon of non-recycled drinking water per day is only 256 pounds for 32 days. Enzyme cleaners for the ship's AutoLaundry might not even require water at TL-15. And the AutoLaundry might be a nice compact 50 pounds, that everyone shares.

So you're not even looking at a half ton per person. Possibly not even 800 pounds. Maybe with the weight of all of the pipes and ducts you might be at 800 pounds. With shared freshers, it would be less.

Of course, I'm thinking about a 4 stateroom Scout/Courier where everything would have to be compact.

Fans and Pumps for the ventilators and plumbing are going to be needed, and not just at the recyclers. Also, would you eat TV dinners or microwave dinners for one month with no break? Are you just drinking water? Lastly, you are assuming Tech Level 15. I was under the assumption that Tech Level 15 was not at all common in the Imperium.

Do you think it would be a lot more mass? If it's pumping into a common space, you have to divide the mass by how many people it can maintain.

Also, would you eat TV dinners or microwave dinners for one month with no break?

I'm sure the food storage and quality would get better, unless a TL-15 society would only be using TL-8 or TL-9 food production methods.

Imagine a future where TV dinners taste great AND are good for you!

Are you just drinking water?

Beverage flavoring packets would come with the food.

Made with great tasting, High Tech food processing methods!

Lastly, you are assuming Tech Level 15. I was under the assumption that Tech Level 15 was not at all common in the Imperium.

I am assuming TL-15, yes. Something for other Tech Levels to aspire to, maybe?

It's odd, the way people think about food on starships, and this isn't the only thread it's been brought up in, that people think it won't be better in the future.

I use 4 deck plan squares per stateroom, and then use the other 4 for corridors and communal spaces.

Life support and environmental stuff for the whole ship I assume is included in the 20t bridge

That only works for very small ships. Once you get larger you have to account for it. But, if you stick to ships with a few staterooms that's fine to account that way.

The figures take into account for high passage ships were baths might be common. Luxury items. In that case you need ability to have simultaneous access to larger amounts of water. The figures include 100% closed system for food/water though. CO2 is cracked rather than removed) Food IMTU at Avg Stellar+ is handled by MealMakers TM that use basic chem building block supplies to build food. Compact mass indeed. They make food that is indistinguishable from fine restraint cuisine.

I looked around for some info on living space... i found a few sources that give 150 square feet is about the smallest space a person can live comfortably. so if the roof is 8 feet tall, the area is 33 cubic meters.

a stateroom is 4 tons, or 56 cubic meters.....

As a very rough rule of thumb: one human will need an amount of mass/volume equal to his berthing space for three months of consumables (water, air, food). This was figured with data from submarines, ISS, and Biosphere II. Of course this can be reduced a bit with hydroponics and a closed ecological system. This also makes an attractive option out of freezing one's passengers in cryogenic suspended animation.

so if we work with a 4 ton space for two crewmen, you would have 28 cubic meters of living space, and 28 cubic meters of stores and support equipment

If the ship is designed for the standard 2 week cruise you only need . maybe 5-8 cubic meters of stores...leaving 20 cubic meters for machinery.

No, it works for ships up to 1000t.

For ships larger than that you get a bigger bridge

If you're going to revisit the stateroom, it'd be good to revisit the stateroom pricing. The two go hand in hand, I think.

I consider up to that size small ships based.

IMTU, back when I was refereeing a game in the mid-80s, the party of PCs had acquired a retired Scout-Courier to refit and renovate as their primary means of transport in the game.

The only true 'indulgence', beyond the standard fittings and must-haves to operate a star-faring vessel, was their antique (circa 1920s era) porcelain-enameled iron bath tub. Such was won in a poker game at an authentic reproduction-reenactment brothel on a planet that celebrated 'Old Earth' Days, a week-long festival that brought visitors from many far-reaching sectors.

Ok I generally go with 0.1 dtons, 0.2 MCr per person for Life Support machinery, coupled to the Life Support supply requirement of 150 man weeks and 150,000 Cr per dTon. With the supplies for Life support I assume that they can be dickered for in each and every port and as such Luxury supplies are also available.

With accommodations ranging up from 0.5 dTons per person. I don't assume that every accommodation has it's own fresher. Though I do assume a dTons worth of Cargo Space for High Passengers and a 0.1 dTon for middle, both Steerage and Low get what they can fit into their berthing area.... generally about 100 kilos.
