Re: [Space/Spaceships] Getting the velocity/Delta V I want with the tech I want
Those were carrying goods (such as spices) that were both lightweight and extremely valuable, rather than more general trade. Also, sailing ships were a technology that was quite economical to run, didn't have to carry their propulsive energy with them and provided a very low standard of living for their crews. Spaceships don't usually meet those criteria.

A.I. ships means background color not center stage gaming. And FTL obviously breaks OP's attempt at hard science fiction.

Re: [Space/Spaceships] Getting the velocity/Delta V I want with the tech I want
If it's any help, TL's aren't set in stone - unless you're seeking to publish a generic article, ie getting paid by SJG. Even then, RAW covers you having different TLs for different technologies. Basically, if the drive you want doesn't work at the settings baseline TL, use a better one.
I wanted an FTL and subwarp that didn't work well with spaceships; realistic TL10 systems actually made more sense. However, strict adherence to the spaceships stats also didn't fit. So I have a hyperdrive and a realistic sublight but the sublight stats are from TL11.

And the freight *better* be high value for its weight. Even at perfect efficiency, getting your ship up to 300 mps and back down uses energy thtn has never been cheaper than on the order of $1000 per pound. So if you can't charge $1000 per pound for it, your freight run is a money loser even if the other operating costs are zero and cargo (and ships!) are free at the point of origin. It's next to impossible to make interstellar trade make sense in a realistic setting, since any civilization that can actually build a starship is going to be able to make anything at home more cheaply than they could ship it back. Even if they have to assemble it atom by atom. And you can send the atomic scale blueprint without a starship.

Who needs AI ships? This is firmly TL 8 stuff, we routinely manage comparable stuff with interplanetary probes.

But I meant as in no humans on board makes the whole trade background color.

The other problem is that realistically, it's hard to think of much in the way of goods that justify expending several hundred gigajoules per kilogram, there's really not much that you can't synthesize for less. Other than information, which doesn't need a ship at all to trade. |

Re: [Space/Spaceships] Getting the velocity/Delta V I want with the tech I want
Checking the original post, you are right that I made an assumption. OP never wrote that they intended for it to be center stage.
