Among the many things never considered in Traveller ship construction rules are all the pipes, air ducts, conduits for fiber optics and wiring, etc. Most of which should either be run behind removable panels or through Star Treks ubiquitous "Jefferies tubes" so they can be accessed for repairs and ...

The problem is we don't really know how much life support equipment is required to maintain a person because the rules have never stated it. Does anyone else have a ratio of life support displacement per person? Something like 1dton can support 10 people? That is indeed a problem. We can say for su...

2 dT per person doesn't sound like barracks to me, it sounds like double occupancy staterooms. That is to say, perfectly standard accomodations. Hans Barracks accomodations are more spartan then staterooms, they take 2dtons but don't allow double occupancy. But if they take up the same tonnage, why...

Since the Cr2000 is a fixed value and refers to only basic food stuffs what is it that the passengers are eating and drinking? It costs the same Cr2000 for a high passenger as it does for a middle passenger or for packing in two of your unwashed crew. Or as we have said, when the stateroom is empty...

Well-known fact of space travel: Life support in real space cost exactly the same as life support in jumpspace. Checking JTAS asteroid mining rules, apparently not (: How do you figure that? I don't think they'll change the rule in Mongoose as it would mean errata for the life support cost line in ...

* 1 person requires 1 kg of food and other essentials per day costing Cr 25 per kg * 1 ton of such supplies will support 2000 person/days at a cost of Cr 50,000. * That translates into 285 person/weeks at Cr 175 per week. That sounds much more reasonable. EDIT: Actually, thinking it over, it doesn'...

OK, misunderstanding there somewhere. I seem to recall (and should check before blathering on, but... ;) ) that spaceships and small craft only need the (small craft) cabin, which is only half the size, 10% the cost, and has no associated life support costs. That only starships need a stateroom wit...

Yes, and that is covered by power consumption. The amount of consumables that are consumed, however, is less when there are less people to consume them. So basing the cost of consumables consumed on the number of staterooms Does. Not. Make. Sense. There may be costs involved that are not related to...

Agreed, though I prefer to give a good try at making the rule work before chucking it. I think a good try at making the rule work has been made. It failed. And I think the ALF (Alien Life Form) idea works. Granted I haven't been terribly verbose above, just the barest outline of the idea. And there...

...hey, the rule is stupid, I think we can all agree on that. I think calling it a Tax is equally idiotic. So do I. I don't think either explanation work. I doubt any explanation will work (though I'd be delighted to be proven wrong). That's why I advocate changing the rule . Just as my approach to...

The ship's environment isn't controlled on a stateroom by stateroom basis, but it is controlled by sections enclosed within structural bulkheads. Partition walls and doors are not airtight; pressure, humidity, heating/cooling, etc. cannot be controlled per stateroom. Recycling and filtration of wat...

One of the things that occurs to me in this thread is that while the "life support" cost is quoted PER STATEROOM, it's not really for what one would visualize as "the stateroom" alone - remember that when you're constructing a ship, half of the allocation for a stateroom is actually for public area...

A liter of water, a kilo of food and a kilo of LOx and other supplies per day - assume decent but not perfect water and air recycling and you're good. 0.1 dtons per person per month. Actually, you'd better assume very efficient water recycling. Human metabolism generates water. If you don't extract...

What I get from this is that "supplies for the Life Support" system mean something other than food or water, and presumably oxygen as it is trivial to crack water for air. I think that could break down into two elements: * Replacement of filters, rapidly wearing-out parts or specialized catalysts t...

We are getting a little focused on just food here. Lets look at this from another angle. Food is a sizable part of living expenses. For a generic figure, I believe one third is a good number. Another third would go to lodgings, and the third third to everything else (I'm unsure of a good term for t...

Classic Traveller was not quite as problematic in some ways. Book 2: Starships differed from MGT in two ways: (a) The expense was "per trip (2 weeks)" for staterooms and "per usage" for Low Berths. (b) It was only applied to occupied staterooms or berths. This is much more logical, especially for l...

Dates before zero are negative, dates after are positive. For example, Terra discovered jump drive in -2431. The Imperium wa...

I agree completely with Ian. The life support rule is broken. In addition to the points Ian made, there's another problem. At Cr2000 per fortnight, the difference between 9 days worth of life support (the average that a passenger consumes in a trip) and 14 days is significant. It's about Cr700 per p...
