[Spaceships] Benchmarks for spacecraft cost
In GURPS Spaceships spaceship components have the following prices per ton.
Code:
Armour, ice $ negligible Armour, stone $ negligible Armour, steel $ 4,000 Armour, light alloy $ 10,000 Armour, metallic laminate $ 20,000 Armour, advanced " " $ 40,000 Armour, nanocomposite $ 100,000 Armour, organic $ 6,000 Armour, diamondoid $ 200,000 Armour, exotic laminate $ 400,000 Controls $ 40,000 Defensive ECM $ 200,000 Comm/sensors, enhanced $ 40,000 ", tactical or science $ 200,000 ", multipurpose $ 400,000 External clamp $ 2,000 Factory $ 1,000,000 Habitat $ 20,000 Hangar bay $ 2,000 Jet engine $ 200,000 Mining/refinery $ 20,000 Open space $ 1,000 Passenger seating $ 6,000 Power plant, chemical $ 10,000 " " , fission $ 60,000 " " , fusion $ 200,000 " " , antimatter $ 400,000 " " , super fusion $ 600,000 " " , conversion $ 1,200,000 Ramscoop $ 2,000,000 Reaction engine, chemical $ 40,000 " " , HEDM $ 60,000 " " , electric $ 30,000 " " , fission $ 100,000 " " , nuclear pulse $ 200,000 " " , fusion $ 200,000 " " , AM thermal $ 100,000 " " , AM plasma $ 100,000 " " , AM plas torch $ 200,000 " " , super " " " $ 400,000 " " , AM pion $ 200,000 " " , AM pion torch $ 400,000 " " , TC torch $ 400,000 " " , Super TC torch$ 1,000,000 Robot arm $ 200,000 Soft-landing system $ 10,000 Solar panels $ 100,000 Space sails $ 200,000 Weapons $ 1,200,000 " , spinal mount $ 1,000,000 - ammunition, cannon $ 100,000 - ammunition, missiles $ 1,000,000 Fuel, water $ 20 " , coolant $ 250 " , ionisable (argon) $ 180 " , rock dust $ 2 " , rocket fuel $ 800 " , hydrogen $ 2,000 " , jet fuel $ 4,000 " , HEDM $ 6,000 " , AM & hydrogen/water $ 20,000 " , nuclear pellets $ 50,000 " , uranium-salt water $ 100,000 " , AM-boosted H2/H2O $12,000,000 " , nuclear bombs $ 250,000 " , 50% AM $10,000,000,000,000 What benchmarks can we establish for what things ought to cost, eg. how do comm/sensor arrays compare to real life avionics prices? What does a Pratt&Whitney aero jet engine cost per ton? Are airbags really $10,000 per ton?

Re: [Spaceships] Benchmarks for spacecraft cost
Hm. I think our first problem would be to establish what kind of dollar we are using. Does 1 USD at current value = 1 GURPS dollar?
And Jet Fuel is apparently currently 3.10 USD/gal. Also, what are we looking at for price? If we can find something(such as jet fuel) available currently, thats all well and good, but how do we assign value to steel spaceship armor? Current bulk cost of steel? Whats the cost of turning that steel into armor shaped to fit on a craft? I'm sure you've already got some ideas about these questions, I think it's just good to define our assumptions before we attempt this, so we're not working at cross-purposes. |

Re: [Spaceships] Benchmarks for spacecraft cost
Is posting the complete price list from Spaceships strictly necessary here?
I mean it is a copyrighted work... |

Re: [Spaceships] Benchmarks for spacecraft cost
It's a credited excerpt, it's not nearly enough to build your own spaceships without the book, and I don't think that information is available in that manner in the book, so it's probably all right.
Of the questions he raised, the jet fuel might be overpriced, and the argon seems underpriced in comparison to the hydrogen, so I'd be interested in hearing if those were correct or typos.

So we can squirt that copyright bogeyman with a water-pistol and get on with what we were doing.

Hydrogen and Argon look to be roughly right in comparison, but both about an order of magnitude cheaper than today. If we get much cheaper electricity (fusion, better solar panels) this is semi-plausible.
