Semi-OT: A General Tech Question Thread for me :)

[El_Phil]

The explanations are never simple, or the details of it aren't, and in general people do tend to go 'Arrrrrrrrrrrgh!' and run off screaming at the concepts. The maths are worse. You can simplify things, but then you risk lose the meaning. "Things should be as simplified as far as possible, but no further." Einstien I believe.

As for the gravity when a ship stops or is at constant speed your crew should be floating around. Now this isn't really very neat, honour guards drifting around the room, coffee drifting towards the screens etc, but it's the way it goes.

Just as a side point, I do remember something about G force tolerance being massively variable. A big naval aviation study ,if I recall, had variance from 2.5 to 7.5 for blackouts in pilots/personnel. Of course you'd hope it was the pilots at 7Gs and the cleaners at 2.5 but still.

Well someday maybe someone will figure out how to create a gravity field so for the sake of keeping things nice in this story I'll just assume that I Know not very "scientific" but I don't want to have to deal with the even more complicated and pain in the butt problems that come about when you have rotating sections.

[El_Phil]

Nothing wrong with a rotating section, except when it stops rotating of course...

Now I remember a name 'Alistar Reynolds.' anyone read any off his stuff? There's a guy who takes things seriously. As in journeys take years/decades as light speed is the limits and people have to wear exo-suits when the ship accelerates at high Gs. Masochisticly hard science really.

[Starhawk]

Trust me El Phil I've read a few different opinions on the "problems" that come in with rotating sections, which is in part why I asked about that idea here.

I've heard any number of things like friction, amount of power required yadda yadda that people threw at one another as to why or why not rotating sections would work.

Rule number 37: There is no such thing as overkill. There is only "Open Fire" and "Time To Reload".

[El_Phil]

Given the choice between floating into scalding hot coffee when the ship stops accelerating or a rotating section I know what I'd choose... Full on artificial gravity.

If you don't like rotating sections then perhaps consider the rotating ship. An idea I got from a Heinlein book, essentially the enire ship 'rolls' along. No friction or bearings to think about, full gravity for the whole ship (admitedly variable strength, but you can't have everything) it seems clever. I haven't put that much thought into practical issues, but none are jumping up at me right now.

Wouldn't a rotating ship require alot more thrust to accelerate. Manuverability would also be greatly reduced, I believe, as it would be harder to change directions. Another problem turning when spinning is that the thrusters to move you into a turn would be rotating and would create a couple of problems, depending on how much you wanted to explain.

They would need to be pulsed on ond off in a serial order to keep thrust on just one side of the ship.

If you wanted to go farther into it, then that wouldn't work either as each thruster would still fire in an arc, not just at one point. It would be massively unstable.

I can't think of any way to explain around this, and there may be other problems I haven't thought ofas well.
