Re: Low tech ships - Need help

Is the hydrogen in the fuel bladders under pressure? Because capacity is comparable to actual tank capacity. I’ve been assuming it must be. Otherwise it’s hard to see how a ship could carry enough hydrogen to meet its needs. Today’s vehicle applications typically use a pressure vessel in the <100 M...

I suppose a smaller ship would be a Difficult task, while a larger one might be Routine. Hopefully the Type R makes its Jump roll!
It did. But it emerged closer to the pirates than the Travellers.... :D

Re: How close are orbital starports?

OK, this leads to a question that came up in my campaign last session. You are expecting the arrival of a freighter insystem. You know the mass of the freighter (a standard type R), what system it’s arriving from and when it’s due to arrive. How closely can you predict the point in your system where...

Re: Low tech ships - Need help

Hydrogen can be stored under high pressure or possibly chilled to near-absolute zero to reduce the volume needed for storage. Although the way the collapsible bladders are described the pressures are likely limited - probably no more than 100 MPa, maybe only 50 MPa.

Re: How close are orbital starports?

That implies the position error is not dependent on the length of the jump. Which might well be a consequence of the physics but feels a bit counterintuitive.

That could be a reason for regular re-surveys of known systems - to improve accuracy of jump calculations.

Re: Missile Drive velocities

I think you could assume that inertial compensator tech evolves in step with maneuver drive tech - if your world can build a 6G maneuver drive the inertial compensation comes in as part of the package. Which leads to thought that reaction drives don’t follow this model and thus would subject their c...

Re: Vehicle damage clarification

For a better fit with MgT2 you might want to tweak the modifiers for the Open Frame option. I think the points of Hull per Space for the different Frame types was supposed to do something similar but maybe it didn’t quite hit the mark. I like the proposal for spacecraft but I propose adjusting it ba...

Re: Low tech ships - Need help

I think you could justify a faster launch rate from a single hangar that holds multiple ships- perhaps 30 min for the first ship to account for securing and depressurization of the hangar and maybe one per ship turn after that. Launch tubes might provide a tactical advantage some navies may consider...

Re: Modular hull question

We may need to distinguish between modules (perhaps more properly modal containers) which can be quickly and easily attached or detached and modules which are meant to be accessible from within the vessel. Attaching the latter may be more like docking a small craft as you have to ensure engagement o...

Re: Suggested prices and ways of disciplining

Debt slavery might not be uncommon as a form of judicial punishment - work as a slave laborer for X years until your debt is paid off. Or indentured servitude, which was pretty common in the US in colonial days. IMTU I’ve created a multi-world polity on the Imperial border whose society has non-here...

Re: Orbital Belts

I agree with Infojunky - massive civilian orbital facilities would likely be most common on smaller high-pop worlds (or worlds with limited usable area). One of the central worlds in my current campaign is just such a place. And was a great setting for the first adventure where the Travellers were c...

Re: Low Berth vs Fast Drug

There are two aspects that would come into a discussion of safety. One would center on the effects of the technology itself - does it work well with all species, does it have potentially harmful side effects, does damage to the body accumulate over time, etc. This is usually what people mean by safe...

Not sure solid shot makes sense for a gauss weapon - aren’t the needles solid (I.e, don’t fragment or flatten on impact) already?

Re: Gauss Weapons - Zero-G?

I vaguely recall a sci-fi novel a decade or so ago that featured a wasp-waisted hypersonic bullet. Which according to the author would theoretically accelerate as it traveled due to a quirk in the aerodynamics - riding the sonic shock wave or something like that. I think the author was Travis Taylor...

Re: Gauss Weapons - Zero-G?

Not convinced that a real-world gauss weapon would create virtually no heat. Even if the coils are super-conducting (almost certain) other components in the system probably won’t be and the cycling of the intense magnetic fields involved in those parts will generate heat. The air inside will heat up...

I think a DM+1 makes more sense. Phavoc has two good points. It’s highly that most starports would have some free traveller’s guides, electronic or otherwise - thanks to the local tourism bureau if nothing else. (Granted at a D starport this might be a bulletin board w/ ads or business cards tacked ...
