Re: Low tech ships - Need help

Should a ship have engineers for solar panels? I would. Given their size and output they have to be thin films, rather than rigid panels. At a guess they have to be continually repaired for micrometeorites to prevent ripping and shredding when folding or unfolding. To keep fuel within reason, I've ...

Re: Low tech ships - Need help

The size of a ship, its components and cargo is measured in displacement tons, or simply tons. Yes, ships are measured in displacement tons ≈ 14 m³. So, for example, a light autocannon has a Mass of 0.25 tons, which is equal to 1 Space. Yes, vehicles are measured in Spaces ≈ 250 kg = ¼ tonne. Not t...

Re: Low tech ships - Need help

I wonder about that at times; I think it's an "implications of technology" thing. At TL7 a ship won't have fancy reactionless M-drives; every "dodge" is going to require precious reaction mass. Short range is something like 1 000 km. With a muzzle velocity of 2 000 m/s or 2 km/s it would take 500 s...

Re: Quark Reactors

What does that have to do with it being in a starship that can travel FTL? It's a meaningless distinction since Traveller fusion also does not exist. Neither exist in reality. Hydrogen fusion exists today, we just can't keep it stable for more than a few ms. We have no idea how to even begin to exp...

Re: Low tech ships - Need help

I'm thinking that a ship firearm like weapon would do 1D damage, would have a range of short, and cost maybe 0.25 MCr. Maybe give it the autofire trait. https://i.imgur.com/IwtK182.png You will not hit anything that can manoeuvre at 1000 km (Short) with a cannon, but perhaps Close (~10 km), and cer...

Re: Quark Reactors

Fusion reactors require fuel to be fed to them to maintain the reaction, as would a quark reactor. Why does it matter if it's a self-sustaining reaction or a reaction based upon continual feeding of quarks into the fusion process? For the quarks there is no fusion process, each pair of Λ particles ...

Re: Quark Reactors

Since we can't do that with hydrogen currently, there is no difference between quark and hydrogen fusion. But subsequent calculations showed that it would be impossible to cause a chain reaction with quarks because they exist for too short a period of time—approximately one picosecond—not long enou...

Re: Low tech ships - Need help

Low tech weapons. The only weapons I see at TL 7 are missiles and torpedoes. I'm hoping for more variety, such as firearm ships weapons. I'm trying to avoid relying on missiles being the only weapon for fighters. You can use small weapons, such as auto-cannons. The range sucks, though. Fission powe...

Re: Quark Reactors

calculations showed it took 230 MeV to fuse such quarks, but doing so resulted in a net release of approximately 138 MeV, which the team calculated was approximately eight times more than the amount released during hydrogen fusion. It's eight times more energy per fused particle, not eight times mo...

Yes, of course.

But you will not find useful amounts of antimatter in nature either, so you have to make the antimatter, using a lot more energy than you will get back by annihilating it.

Re: Quark Reactors

And where do you get the free quarks from to fuse in the first place? Unmaking protons and neutrons to free up quarks just so you can fuse the quarks... Bottom quarks, as used in the theory, are heavier than protons, so cannot be contained in the protons. You have to make them by concentrating ener...

Re: Quark Reactors

For best performance you need bottom quarks, which you will not find in nature.

You have to make the quarks, e.g. in an accelerator, and then use it before it breaks down or combines into a baryon in about 0.000 000 000 001 s.

Re: Gauss Weapons - Zero-G?

On the other hand, if it's pulled forward like attraction rather than repelled, do you get a forward momentum rather than recoil? No, "pushed" or "pulled" is just a choice of frame of reference, the result is the same. A net result force on the projectile will result in an opposite force on the wea...

Re: Quark Reactors

Seems impractical: But subsequent calculations showed that it would be impossible to cause a chain reaction with quarks because they exist for too short a period of time—approximately one picosecond—not long enough to set off another baryon. Each quark has to be manufactured, then collided very care...

Re: Gauss Weapons - Zero-G?

There is always drag... I don't think the shooter will feel the pulses even if discrete coils are used to accelerate the projectile. If we accelerate the projectile to 1000 m/s in a 1 m barrel (at constant acceleration): v = at, so at₁ = 1000. d = at²/2, so 1 = at₁ × t₁/2 = 1000t₁/2 ⇒ t₁ = 1/500 s i...
