TL 8 allows space habitats and fusion power, interplanetary travel and etc. Fusion power opens up vast possibilities, as does genetic engineering. Are they aliens ? Z-G adapted humans or aliens ?

Primitive space habitats at TL 8.

Permanent space habitats at TL8. (MGT).

Isn't fusion TL9?

Tech 8 (MGT).

They don't even have grav drives either.

There are other ways to travel in space at tech 8. ( MGT).

Well considering that a TL 8 AT gun has an effective range of 305 miles I have no doubt that trillions of people can live on an asteroid belt at TL 8.

I'm trying to see if there's any way I can justify an adventure in a gas giant - perhaps stranding them on some kind of floating kelp-analogue forrest/sargasso in the calmer parts of an eye storm ( say, an anticyclonic disturbance - a big ass partially formed high pressure trough). Is it likely that there is a level where the pressure isn't too crushing (say, less than 2-3 bars) and the temp above freezing, on a GG with a max Grav of 1.1? (saturn sized or less, I think)

Any suggestions ?

Ever read Michael McCollum's "The Clouds of Saturn"?

That sounds interesting. I'm assuming that since you recommend it, it doesn't suck ?

It works well for the OP's planet too, it would seem.

Well, The 20mm gun mounted on the KGB orbital Salyut station* in the 70's probably had that kind of range.....so...sure. I guess. ;)

Michael McCollum's stuff is generally worth the read, yes. One of his books ("A Greater Infinity") appeared in Analog SF as a set of short stories, to give you an idea of where he fits in SF.

I love getting exotic atmospheres too. What sort of liquid chemicals do you think would cover 90% of Galliant? Must be something neat cause of the temps.
Click to expand...

I was thinking of posting here actually, asking the science-heads what it might be (after all, it needs to be something that stays around in the 80+ degrees - though I imagine the dense atmosphere helps that, which probably means it rains all the time.

So yeah, I LOVE the generation system.

Oh, and a tip for those who feel the incidents of planets is too high - I went with the lower probablility option - only a 5 or 6 to have a planet.

It's water. Atm D has to be an N2/O2 mix - but it's a really dense one. So the ocean is liquid water (if it wasn't, the atmosphere would be different and exotic, which means it'd be A-C). I'd imagine it'd have 100% cloud cover too and high greenhouse effect (high albedo to reflect sunlight, but what does get through gets trapped by the thick atmosphere, which would push the temperature up over time).

Oh yeah, that means the Fl trade code is wrong. Fl should only apply to some atm A, and all atm B and C. Atm D and E should have water oceans, not fluid ones.

Water can still be liquid at high temperatures at high pressures - at 10 atm pressure the boiling point is about 450K (177°C), and at 100 atm the boiling point is about 580K (307°C). Above about 220 atms and 647K though, it's supercritical, which means that you can't tell the liquid from the gas phase.

Up to pressures of about 220 atms, the freezing point doesn't change much though. It does change significantly at higher pressures though, where you can get forms of ice that aren't the ones found on Earth.

That's a weird one anyway though - it's an asteroid belt with trillions of inhabitants, but only has TL8? How does that sustain itself? In the playtest I suggested that such high population systems would require at least TL A, just to be able to have the infrastructure and know-how to support all those the people.

Maybe it's not an asteroid belt at all...but a ring world ?

Very nice. Thanks. Didn't know the higher pressure/higher boiling point stuff.

So, Galliant looks like it's got hi-tech cities using antigrav to float above the clouds I guess.

And totally there would be airship battles. That's why the Sky Marshal is the man of the hour so to speak (and it's a good thing I've got Mercenary to flush that out!).

A finished and inhabited ringworld or Dyson Sphere is pretty much the center of attention for space many, many parsecs around it. You can pour people into one for centuries and not make a real dent on available area. One SF author posited that a Dyson Sphere is actually deadly to those races who discover it and settle it. With all the territorial needs of a race answered, and the desire to explore taken care of, most races will lose their racial ambitions, settle into some corner of the Sphere, and retire from the universe outside.

If you want to designate a ringworld or sphere, use a J or a K for the size in the UWP. That will stand out in a UWP set enough to get your attention.
 
If Galliant had 10 atm pressure and earthlike density and atm composition, then it may be barely breathable by humans at Everest-like altitudes. At 8,000 m the pressure would be about 4 atms, the nitrogen partial pressure would be 3.18 (just less than the maximum survivable by humans before nitrogen narcosis, which is 3.2 atms) and the O2 pressure would be 0.84 atms (rather high). However, given that it's only got 10% land surface, the chance of getting a mountain that high is rather low - the terrain is likely to be much closer to sea level, where conditions are less habitable for humans.

So yeah, probably grav cities.

As I figured. So, floating cities above the clouds (also catching the rays for solar energy).

And I like that the Imperium is so into the place (with all the various bases and whatnot there). I haven't rolled up the rest of the subsector yet (on the first 6 worlds) but it may end up as the seat of the Subsector Duke's government thanks to the Imperial presence and the TL 14.

Anyone else got a groovy planet? 'Cause I got more where that came from...
 
sorry i didn't make it clearer earlier but after rolling up Paradise I decided that it was a penal colony relying on hand me down technology from a much larger more powerful world which was how several billion people could live on an asteroid at TL 8 the larger world had a much smaller population and much higher TL and they decided to ship there undesirables off to a small rock orbiting a near by star.

They have trillions of undesirables?!
 
well once you start sending one batch of "undesirables" to the rock you kinda lose track of reality and start finding new "undesirables" to ship there, kinda like the british empire did with most of the colonies it didnt have much use for.

Plus, well, once there, they breed. How long have they been there ?

If I may be so bold, check out an older thread I started about odd planets- not exactly groovy , but interesting, in a "watching a train wreck" sort of way.
