I would say that the frame of a Model T is actually chiefly wood with a percentage of steel.
No, actually.
The
Cab has wooden parts, but I don't know how much. However, the car has a solid
Chassis of metal, something modern cars don't have. Most of the mass will be in the latter.
Lord High Munchkin said:
Hmm, no offence, but have you seen a Model T chassis?
Not in the flesh, so to speak, but, yes ... photos of a bare chassis.
Lord High Munchkin said:
The chassis is made up of only a pair of straight, light (I'd say almost flimsy, but it obviously sufficed) RSJ-type "I" bars with a pair of downward-facing end arches of the same. It's really basic. There are a few added on items such as: a forward leaf-spring, a rear one, the two axles, and about four light rod struts. That's it.
Indeed, however, the whole thing, including coachwork, is only 560 kilos -- and most of that is in the engine and chassis rather than the coachwork. It's certainly nowhere near the 2000 or so kilos
"Civilian Vehicles" would have us believe!
Even if it was
all wood (chassis, cab, engine, propulsion --
everything), you'd only reduce the mass calculated from CV by about 30%, down to 1400 kilos, which is
still 3x too much :shock:
So the problem remains.

Well, going back to 'Civilian Vehicles' and materials, I assumed that one could use multiple materials as it isn't stated that one can't. I just use the various proportions to come out with a final figure.
But it doesn't even come close to solving the problem, as noted above!

You are "dead-on", as I see it, about being limited by canon OTU. I think that this is the real problem behind the scenes—it isn't a "universal" or "generic" system book, but a supplement squarely aimed at the OTU.
But it doesn't even fill that role, as it has to purport to be able to design any vehicle from TL1 through to TL15 ... and it fails, miserably, when compared to historical examples.
Lord High Munchkin said:
I don't like the way that, for a "generic" book, it assumes that one buys completely into the OTU technology curve. I have other ideas (or at least should have the possibility to have other ideas). There being no alternative tech.
What I do like about the book is the level of complexity (i.e. not too much), but it misses out a lot of things (mainly added equipment, but also TL modifiers) that could have been added with little effort.
Lack of complexity is fine (I preferred GURPS Vehicles #1 rather than #2 because it was simpler, and prefer Stuff! to CORPS VDS for the same reason), but it has to at least resemble reality. With all the above systems you could come close to real world vehicle specifications, with CV, based on my attempts with the Model T you can't in any respect, and with the Hummer, you can for mass and speed, but not for cost.
I agree, there should have been options for a non-OTU tech curve ... and even the materials available make no sense ... you're not going to use Bonded Superdense for any sort of civilian (and for noncombat, and maybe even combat, military) vehicles ... it would be like suggesting that a 1941 Ford should be made out of Armourplate Steel as used in the Iowa class ... silly to anyone who has a clew as to the differences.
Any vehicles I design will be designed with Stuff, with my own mods to some aspects of that system, as far as mass and performance stats are concerned, and I'll use my own prices, based on the reasonable assumption that Traveller (and Space Opera, too, I guess) have never, ever, seriously (or otherwise) used ... that things get cheaper, in relative and absolute terms.
A Model T of 1909 cost $850 at a time when the average wage was under $1000 -- close to 90% give or take. A compact car today costs around $12000 when the Average wage is around $40000, or around 30%. And if you call a Tata Nano a Model T equivalent, at $2500 that's around 6%.
Assuming the salaries given in the MongTrav Core Rules are based on Average Interstellar societies (say TL13) ... or Average Salary 14400 Cr per year (page #87), that would mean that a
cheap Ground Car equivalent should cost no more than, at a guess, 10% of that ... about 1500 Cr, say, or that a
cheap Grav Raft should probably cost no more than 25% of that, or around 3750 Cr.
The idea that Grav Propulsion costs 100-200kCr at TL8 and never gets any cheaper is simply and astoundingly ridiculous ... unless, of course, there is actually no technological progress between TL8 and TL15 ... even if it only represents better manufacturing methods (nanofacs coming online to replace mere production line robotics) such as reduced the price of the Model T from $850 to $290 in ten years, whereas in Traveller you're talking hundreds of years, many many hundreds.
Nope, regardless of whether its
canon or not, it is frankly downright unbbelievable ... :roll:
Things get
cheaper, they do
not get more expensive.
YMMV of course :mrgreen:
