now of course if they can see how stuff is made they will start to steal some of it. so limiting human access to dwarven lands is key. The biggest difference is knowledge of chemistry but there are many thing that can be stolen simply by observing it, esspeically if done on an industrial scale. will it be perfect no, but it can definetely push their technology forward.

@Escapeddentalpatient. but they still won't be able to see anything, space is expanding so fast light literally cant catchup and reach them.

On that timescale wouldn't the universes expansion rate keep them from seeign anything anyway?

@Mormacil 6 degrees is the same as the last glacial maximum, pepperes survived that just fine, the tropics did not deappear they just got smaller. one thing about global climate is changes happen much more at the poles than the equator.
John

jalapenos will do just fine, you are talking about a planet, 6 degrees is not THAT different from current day earth, you will still have tropics near the equator. humans lived on earth when its average temp was 6 degrees.

@Mormacil they are toxic to us too, many of our favorites are, humans have very high toxin tollerances. aniamls still enjoy the taste we are just more tollerant to the toxic effects. chocolate is just as posionous to us as dogs our digestive system is just better at breaking it down. size is also a factor we are big animals so we have higher toxin tollerance than a crow just due to mass. Are they humans sized?

look up cold hardy herbs, they include rosmanry, parsley, oregeno, tyme, mustard, carlic ect you could list at the list of the hundreds of spices that exist and see which are cold hardy.

you need to think about how big your roads are, if there is enough space to fit three sitting side by side thats a lot of wasted space is most are single seaters. Note how current roads are still pretty close ot the the size needed for horse draw wagons everwhere in the world.

@RonJohn lotr is very obviously a soft fantasy setting, and not everyone whats to read or write soft fantasy. also the whole point of worldbuilding is to help creators who are not experts in a given feild, no one can be an expert in everything. By your logic if someone doing PHD level accuracy on the biology of a species but has questions about plate tectonics we should just respond "handwave or get gud on geophysics bro"

this does not work humans are homogenous, you can't get everyone in any sizable society to act the same. soceities were a change in skin color litterally made you legally lesser still couldn't manage it. In your society you will have people outbreeding just on principle.

@DanielB a triceratops face is basically a sloped solid mass of armored bone, topped with two of the largest horns in nature. A pike would cut them but is not going to penetrate unless very strong, stiff, and solidly anchored.
John
Jan 6 19:13
@DanielB, actually pikes are probably far less effective against triceratops, their huge beaked head and frill basically makes a massive armored wedge so you need really good aim for pikes to not just get knocked asside. they are not like horses with a huge flat unarmored surface up front.
John
Jan 6 19:13
@JBH but when you get above a certain size JUMP, is not much of an option. these are not nimble leaping horses, but 12 ton triceratops. Elephants can't cross a 2ft steep sided ditch. You can jump far higher and far farther than a triceratops. so ditches should work really well.

except in an animal the lungs are core organs meaning they are the same temprature as what you are trying to cool, imagine an AC where both heat exchangers are inside the house in the same room welded to each other and air flow is slow. but again the problem was the breath being hotter than the body temp which the OP has changed.
John
Dec 15, 2024 16:00
@FrançoisJurain no I am sayign the dragon as a whole ends up hotter than if it never had the "pump". just like an air conditioner you can make the whole unit (the dragon) hotter to cool a portion of it. an air condition ends up hotter than if it was just passively radiating heat from a circulated fluid. we don't care because we put the AC unit outside but for a living thing it has to inside, AKA part of the body. And an AC can't expel air hotter than the AC unit itself. Of course now the OP has changed that requirment, which was the problem.
John
Dec 15, 2024 16:00
@FrançoisJurain No they don't they move heat and in the process generate even more heat which has to be dissipated passively. only one portion of the unit gets cooler another gets much much hotter. the whole unit ends up having to dissiplate more heat than if it never actively moved its internal heat.
John
Dec 15, 2024 16:00
@FrançoisJurain but the author wants to opposite to concentrate heat AND cool the body, you can't move heat aganst themral equilibrium without generating more heat than you move. you can't heat the air hotter than the body temprature and cool the body at the same time, if you could you could slap a heat engine between them and get infinite energy and heat tried to flow back into the body.
John
Dec 15, 2024 16:00
you can't without violating thermodynamics, if you can concentrate heat like that you have a perpetual motion machine.

Mach 3 would shred/cook a human due to air resistance, it doesn't matter how slow you accelerate. At Mach 3 air resistance heated the SR-71's surface to 800 degrees F and that was a streamlined surface.

why would try to fit all the fuel in a single tank and not just use multiple swappable tanks, then you can just have a big dog robot following along carrying swappable tanks. most modern military vehicles carry only part of their fuel in a tank and carry the rest.

Why wouldn't they be, humans are made of the same stuff as other animals. except for the eggs, human eggs do not contain the cooking relevent parts in chicken eggs. Their real problem is not getting caught by food inspectors who can be very thorough. You can't just lie they take samples and test the DNA of meat.

@Dmyt what will you do with people who are intersex?
John
Sep 2, 2024 13:02
@Dmyt gender is social construct, any reason to seperate people based on it will be by definition based on culture or ideology. Worse becasue diffrent cultures have diffrent definitions of gender you would have ot force a single culture definiton on them to split them up, thus making it again based on culture.
John

Your conditions are mutually exclusive. You are asking for a reason to seperate people based entirely on a social construct, that is not based on culture or ideology.

It doesn't matter which side of the planet its on, so much crap gets thrown into orbit it is basically kessler syndrome for years afterwards. one ot the things that actually heats up the planets atmosphere on the farside is just how much stuff is falling back and undergoing rentry heating.

the problem is if you frame it transport over luxury a plane is just overwhelmingly better at transport for ong distance, a ship can only compete via luxury. Its like asking how to mak ice boxes compete with refrigerators when only considering food storage.

@causative because it takes decades to cataloge them becasue some take many decades to make a single orbit and come anywhere near earth. Near earth asteroids don't stay near the earth. Also some have high albedo absorbing very little light, 0.1 is a lowball NEA. more importantly its not generating any heat, so its not hotter than everything else in the solar system.

@causative which is why refering to near earth asteroids and the amount of light that hits them is a red herring.
John
May 22, 2024 02:52
here is the equation given by john shilling of NASA, Rd = 17.8E6 ( MsAsIsp*(1-Nd)*(1-Ns) )**0.5, Rd = detection range, kilometers Ms = spacecraft mass, tons As = spacecraft acceleration, G Is = drive specific impulse, seconds Nd = drive efficiency Ns = "stealth efficiency", i.e. fraction of waste energy which can be magically shielded from enemy detectors.groups.google.com/g/rec.arts.sf.science/c/-E6r2F8r‌​gnQ/m/… thats for a known 1993 tech detector.
John
May 22, 2024 02:52
@causative if you don't understand what the word reflection means. IR is radiated in every direction reflected light is not. It also assumes all those asteroid STAY near the earth which they don't, what is and is not an NER also changes.
John
May 22, 2024 02:52
@causative source? you are claiming an asteroid reflects nearly all of the sunlight that hits it. which would mean it would be giving off very little heat.
John
May 22, 2024 02:52
whether your detector is in space or an atmosphere will make a large diffrence so you might want to specify.

how did it evolve, bcause out of the multitude of mutations to that system only the successful ones get passed on. mutations in which it does not work occur they just do not get passed on ussually becasue they don't survive.
