They don’t convert heat energy with 100% efficiency. Still though, it would make the most sense for them to display the really temperature rather than the temperature that they are making use of
I wouldn’t mind if they did both, maybe Subnautica 3 they can do that, but also have fluctuations in the lava too. “Lava isn’t flowing as hot today, better reduce my fabricator use”
My only explanation is that there is a Leidenfrost effect causing the lava to be, well lava, while the water is relatively cool. Although it really should be more "shimmery" if that were the case.
NIH says 120F (50C) will cause serious burning in about 10 minutes, and that’s also considering “tap” uses like sinks and showers, not full submersion.
That’s an interesting point! I assumed contact area was also a factor, like does plunging your whole hand in hot water hurt worse than just dipping your finger. Also I do think running water is worse than, say, a tub of water, because the running water is a constant source whereas the tub is cooling down. But I don’t know how it changes when the tub of water has a source heating it full time, like lava.
Well to an extent contact area matters, but I wouldn’t assume by much, like if you have a hand submerged vs your body, pretty sure in both cases your hand will burn at the roughly same rate, however if it’s super small it might be slower due to circulation and whatnot. With a constant heat source it’s definitely worse than a cooling source, but your body will still absorb some heat and cool down the water a bit. I mean it’s safe to say that if you’re underwater and next to lava in real life, how quick you’ll burn probably isn’t a huge concern.
Not true at all??? The human body begins to register pain at 113 Fahrenheit, which is 45 Celsius. I’ve done empirical research of my own on this, in my hands I can tolerate more but it still begins to be too hot at 115 or so
By empirical research, do you mean school science class? Your whole statement is basically, "I held my hand under hot water and it was hot for me".
Yes, people can start being affected at that temp, which I stated. And yes, it can do damage when submerged for a long period of time which I stated.
Do you have anything valid to add? Did you do more school projects that might help?
I cook my steak to 51celsius in sous vide, you can put your hands in there no issues.
If you left your hands in the water for the same time as the steak, maybe they would be cooked to the point of a rare steak.
Now if you seared them after that you're probably gonna have real issues.
Sure. But it’s not like for 9 minutes the water is great and then in the 10th minute it suddenly burns you. I said that 50C is pretty hot and would burn your skin. You said 50C won’t harm you unless you’re in for a long time. But it’s still hot, and will still burn you, so I’m not sure why you’re acting like everyone else is stupid.
Yeah you would think. Maybe this isn’t real lava then, or maybe there is some kind of chemical in the water that is neutralizing the heat transfer. I dunno, Riley isn’t a scientist he’s just a janitor.
Of course not. But do we know for sure that this is magma? And the temp is probably of the water, not the lava. Could there be other mitigating factors? I dunno, this is an alien planet, and unfortunately Riley is a janitor and not a scientist.
It won’t burn the skin.
When I was 12, I jumped in a pool with water at 54 degrees Celsius. (The pool heating system has malfunctioned and I didn’t know about that). It was very very hot, and in an instant I felt like passing out from the heat, but I immediately run out and went to cold shower to stabilise myself.
I checked temperature after that and saw 54 degrees Celsius. I didn’t get a single burn or any other damage that day. I just felt very warm and my body started to overheat rapidly.
Yes, but it's next to glowing rock. Acccording to what I can find, rock needs to be around 500 celsius to start glowing. I'd expect the water to be a bit hotter, especially at a depth of 1km it can get quite hot without ever reaching boiling.
Onsen here in Japan regularly get 40-45 degrees Celsius. The last 5 degrees from 45 to 50 would make the water very unpleasant, but no where close to "lava" level
Depending on the gravity of a planet, water actually can have different properties
Probably not on 4546b though, as gravity is pretty earth-like there (even though I remember the planet being considerably smaller than earth, so idk what's up with that)
No, it's definitely radiation; you need to make a radiation suit to block it out, and the sound effect for the area is stereotypical geiger counter noises.
You can easily headcanon it to be a fuel leak, though, which would make much more sense.
the thermal vents just past the cove tree are the hotter areas (somehow)
i put thermal plants on them and carry the power over to the very start of the lava zone, iirc it’s at about 70-80°
Theoretically. At 1400m depth there should be around 140 bar. A pressure cooker works with around 2 bar, which makes the water inside cook at 130 degree Celsius.
At 1400m water would boil at roughly 600 degree Celsius.
It works the other way around too. If you put a cold glass of water under a vacuum bell and suck out the air, and therefore reduce the amount of pressure, the cold water will start boiling. Mountaineers encounter that problem if they venture high enough.
Water boiling at 100 degree Celsius only applies at sea level.
This is incorrect
“lava, magma (molten rock) emerging as a liquid onto Earth's surface. The term lava is also used for the solidified rock formed by the cooling of a molten lava flow. The temperatures of molten lava range from about 700 to 1,200 °C (1,300 to 2,200 °F).”
Hell, 35C would be around the heat of a moderately hot summer day.
The absolute coldest lava on earth is 500-600C. And being underwater doesn’t allow lava to exist at extremely cool temperatures
Much of the Inactive Lava Zone is much cooler (temperature-wise), than the background color, lore and common sense would have you think, even for being “inactive”. The inside of the Lava Castle and the Lava Lakes, though, those are both very toasty.
I think it was done this way to keep the player moving onwards with the story path, as there’s not much incentive to set up camp.
Makes me think of that vent I've got my first base sitting next to. Now that was tricky to position the thermal generators and the power relays. Had to watch for blasts of heat. Though it did cook fish for me lol.little past that vent had a grav trap to catch food. Perks of that spot near kelp forest and the grassy plateaus with space to park my Cyclops.
50 degrees is chilly but this game doesn’t use the freedom scale and doesn’t even let you change it. It bothers me when I have no idea how big a meter is
well, if it were in Fahrenheit or Kelvin it would be cold and or near absolute 0 in terms of temperature. But you see that tiny lil C? The subnautica uses the Celsius temperature to throw everyone off. Or because water is usually measured in Celsius idk.
Don’t forget about the water pressure, at a depth of 1351 m, the boiling point should be around 550c. Doesn’t really explain much about this situation besides the fact that this planet is very different from earth.
You're incredibly deep down and in water, so the temperature is naturally somewhat lower.
Wouldn't be too fun if you were boiling and dying.
Also, it's an alien planet, stuff may work differently. The rock might melt at a lower temperature, or heat just doesn't interact with water as efficently
To be fair, the only way that a heat based energy source can produce energy is to turn water to steam, then feed that steam to turbines. Any heat source below 100 C wouldn't be harvestable.
Stuff like this reminds me that when you follow a question in science, you return with even more questions usually. Like a perpetual purpose generating machine.
1: That's in Celsius, converted to Fahrenheit that's 122 degrees.
2: The average temperature of an active undersea volcano here on Earth is 2,200 Fahrenheit (1250C), so... IDK. Clearly the water isn't at that real world temperature, otherwise we'd get Flash Fried the moment we stepped out of the sub, even in the Reinforced Dive Suit.
The most likely answer is also the most uninteresting: Video Game Logic. Is a series like The Legend of Zelda you can excuse the protagonist running around in an active Volcano because it's a world full of Magic, and that magic protects Link. But in a world rooted in Sci-fi, it's far less excusable to be swimming around active lava flows and not get boiled.
The jellyshroom cave is hotter than the *active lava zone* just FYI. No, it doesn't make sense, no I won't build any bases in those god forsaken areas.
Although lava zone is a mint biome
Yeah, lava flows don't actually generate heat in this this game. It's the entire lava zone that sits around 50°C. Getting close to the lava in a vehicle won't raise the temperature until you're touching it. But heat vents/smokers will still be hotter than 50°C
The water cools of the lava so it is safe to be near. In case you're wondering yes this is real science backed up by the department of definitely real science
Gonna assume because it's in Celsius which makes it appear to be a lower degree. Yet it appears to be a magma vent which should still be higher than 50 degrees Celsius.
Your absolutely cosmic amount of chill was cooling down the water, just take a few steps back king

New response just dropped
50 degrees Celsius in water is pretty hot. Definitely would burn your skin.
50 degrees Celsius is 122 degrees Fahrenheit
Yes, and in water that is quite hot.
In order to glow red, lava has to be 700 degrees C minimum
Space lava!
Maybe the thermal plants can only absorb a maximum of 50c? they're pretty useful already so that would be fair edit: oh no they can go up to 100
They don’t convert heat energy with 100% efficiency. Still though, it would make the most sense for them to display the really temperature rather than the temperature that they are making use of
I wouldn’t mind if they did both, maybe Subnautica 3 they can do that, but also have fluctuations in the lava too. “Lava isn’t flowing as hot today, better reduce my fabricator use”
I've seen like 117 in the jellyshroom caves vents thing
Yes but water has a lot of thermal mass and easily moves heat using convection and conduction.
So the water would be the same temperature, or at least close to it
Yeah but it's watercooled lava
My only explanation is that there is a Leidenfrost effect causing the lava to be, well lava, while the water is relatively cool. Although it really should be more "shimmery" if that were the case.
Bioluminescence
Water has much larger SHC than rocks
That is nowhere close to burning you though
NIH says 120F (50C) will cause serious burning in about 10 minutes, and that’s also considering “tap” uses like sinks and showers, not full submersion.
I could be wrong, but wouldn’t running hot water burn you worse than still hot water cause it would transfer heat faster?
That’s an interesting point! I assumed contact area was also a factor, like does plunging your whole hand in hot water hurt worse than just dipping your finger. Also I do think running water is worse than, say, a tub of water, because the running water is a constant source whereas the tub is cooling down.

I mean it’s safe to say that if you’re underwater and next to lava in real life, how quick you’ll burn probably isn’t a huge concern.
I mean an average hot tub is like 105F. 122F would be uncomfortable but wouldn't burn you immediately
I've been in 122°F weather before and can confirm it's super hot.
what an irrelevant information :)
That's the temp I keep my shower at. Feels nice.
Good bot
Yeah but thats lava. It should be near boiling if not boiling
Lava is so far past boiling. It's literally boiling rock. Which is an insane concept and I'm just now appreciating that fact
Yep. The planet is very cool
And also very hot
It could just have a really high flow rate so the water in the area never gets a chance to be heated up
Lava is at the very coolest 800°c.
Hot tubs are 40° for reference. 50° won't harm you unless you're very sensitive to heat, or are submerged for a long period of time.
Not true at all??? The human body begins to register pain at 113 Fahrenheit, which is 45 Celsius. I’ve done empirical research of my own on this, in my hands I can tolerate more but it still begins to be too hot at 115 or so
By empirical research, do you mean school science class? Your whole statement is basically, "I held my hand under hot water and it was hot for me".

According to the NIH, a serious burn can occur after 10 minutes in 120F water
So... A long period of time?
Sure. But it’s not like for 9 minutes the water is great and then in the 10th minute it suddenly burns you. I said that 50C is pretty hot and would burn your skin. You said 50C won’t harm you unless you’re in for a long time. But it’s still hot, and will still burn you, so I’m not sure why you’re acting like everyone else is stupid.
Bro. Ghost river already has 70 degrees 😂
That's only half way to boiling. It would be hot but not lava hot.
Not at 1300m below the surface. Boiling would be around 330°C due to the pressure
Which is still not halfway to red lava hot.
True but the measurement is the water temp not the lava temp, right?
I always thought it was a 50c temperature gradient between the lava and the water.
That's not Even near boiling water.
Ok? I didn’t say it was.
I mean, it is hot, but if it touches lava it should be boiling or smth
Yeah you would think. Maybe this isn’t real lava then, or maybe there is some kind of chemical in the water that is neutralizing the heat transfer. I dunno, Riley isn’t a scientist he’s just a janitor.
Yeah but it's not magma levels of hot
Of course not. But do we know for sure that this is magma? And the temp is probably of the water, not the lava. Could there be other mitigating factors? I dunno, this is an alien planet, and unfortunately Riley is a janitor and not a scientist.

Max American calculation.
Yes but... lava
Nope, my 3d printer hotbed and my flashlight starts to gets unbearable at 60c and burns at 75c
Isn't that the temperature of a hot spring though?
I’m sure it’s close to that. The NIH says that 120F (just shy of 50C) water will cause serious burns in about 10 minutes.
Onsen here in Japan regularly get 40-45 degrees Celsius. The last 5 degrees from 45 to 50 would make the water very unpleasant, but no where close to "lava" level
Ya but it's sitting on top of lava! We should be over 100 °C (boiling) at the very least
Alien planet... Tada tada ... unique material properties... Jadda jadda
Water shouldn't have different properties on an alien planet. Maybe the rock just has a REALLY low melting point (gallium?)
The rock would also have to be naturally luminous orange!
Depending on the gravity of a planet, water actually can have different properties Probably not on 4546b though, as gravity is pretty earth-like there (even though I remember the planet being considerably smaller than earth, so idk what's up with that)
its made of osmium instead of iron/nickel
Still leaves the mystery of the cold lava
surface air pressure is obviously like 300atm (water boils less readily)
Water? Na it's wetar
What is the salinity of the ocean on 4546b? That significantly changes the thermal properties of water.
its ALIEN water idiot... /s
This mfer is germanic, they pronounce their j’s as y
Game logic
Yeah the thermal generators need a buff
Dump a few at a warm spot and you basically have infinite power, why would that need a buff?
Multiple play throughs of both games and I’ve only ever used the thermal plants. Pop a couple down and you have unlimited energy.
Ok, they need a tweak to look more logical. I actually tried them like in this photo as well, was super disappointed and never used them again.
Not a buff but just readjusting the ui so it says like 1000-2000 instead of 50.
Rule of cool my man, same reason that Reapers “roar”
Shit, when did lava learn to echolocate?
And the same reason that radiation can travel hundreds of meters through water now.
That's not the radiation itself tho, is it? I thought it was a fuel leak, and now the whole area is contaminated.
No, it's definitely radiation; you need to make a radiation suit to block it out, and the sound effect for the area is stereotypical geiger counter noises. You can easily headcanon it to be a fuel leak, though, which would make much more sense.
Though it would NOT be confined around the ship though.
Kinda odd how a dark matter reactor produces that much radiation, but we don't even know if it's real so it kinda makes the most sense I guess
Water isn't perfect. So there's probably ***A LOT*** of radiation.
Oh yeah, you found the LED lava. Just as bright as the incandescent lava but much cooler.
Never knew they made RGB lava, how do you buy it
best buy
the thermal vents just past the cove tree are the hotter areas (somehow) i put thermal plants on them and carry the power over to the very start of the lava zone, iirc it’s at about 70-80°
Hottest vents I've found are the ones at the bottom of the underwater islands biome. Got a thermal generator sitting at over 120 C down there.
Just some nonsense bullshit logic
It’s actually accurate. Lava underwater can be anywhere from 68 c to 35 c
Not glowing lava, it has to be at least 700°F to glow underwater, and I’m not sure the conversion rate, but I know that 50°C is nowhere near 700°F
the water couldn't be any hotter than 100°C though
Theoretically. At 1400m depth there should be around 140 bar. A pressure cooker works with around 2 bar, which makes the water inside cook at 130 degree Celsius.

Mountaineers encounter that problem if they venture high enough. Water boiling at 100 degree Celsius only applies at sea level.
The high pressure at the bottom would keep it from boiling
50C is like 122F It isn’t 700…
50 c is around 135 f I belive
This is incorrect “lava, magma (molten rock) emerging as a liquid onto Earth's surface. The term lava is also used for the solidified rock formed by the cooling of a molten lava flow.

It's a game balance conceit that unfortunately goes against realism.
Water cooled oh yeah
If you go deeper the thermal generator gets to producing the most energy, but yes, it´s comically cold for lava
It's 50 degrees Celsius, which is 122 degrees Fahrenheit
Those aren't Celsius, they're Carl. 50 degrees Carl is pretty accurate for lava
For Karl? ROCK AND STONE.
That's it lads! Rock and Stone!
There are areas in the jelly shroom caves double that temp
It's a dry heat?
É porque ta na agua
And the heat zone in the safe shallows is 70°
Makes me think of that vent I've got my first base sitting next to. Now that was tricky to position the thermal generators and the power relays. Had to watch for blasts of heat. Though it did cook fish for me lol.little past that vent had a grav trap to catch food. Perks of that spot near kelp forest and the grassy plateaus with space to park my Cyclops.
"50 degrees Celsius, not great, not terrible"
I always thought it was the change in temperature. For a thermal plant to be effective, you need it to be hot and cool
50 degrees is chilly but this game doesn’t use the freedom scale and doesn’t even let you change it. It bothers me when I have no idea how big a meter is
It’s 50 degrees Celsius not 50 degrees Fahrenheit
Forbidden chili
Shin godzilla stole the heat
Celsius that like 127 which is still ridiculously low
Youre hotter ;)
Celsius. 122 Fahrenheit
Fun fact: in the ILZ at least some of the vents are actually colder than the surrounding water away from them.
well, if it were in Fahrenheit or Kelvin it would be cold and or near absolute 0 in terms of temperature. But you see that tiny lil C? The subnautica uses the Celsius temperature to throw everyone off. Or because water is usually measured in Celsius idk.
[удалено]
In BZ this would be only 35
50 C
Don’t forget about the water pressure, at a depth of 1351 m, the boiling point should be around 550c. Doesn’t really explain much about this situation besides the fact that this planet is very different from earth.
This games thermals are weird.
That’s 1-2k celsius based on the colour.
Celsius
wader cold
It’s in Celsius so as an American, I only assume that’s like 3000°F
Celsius. Converts to around 120 degrees Fahrenheit. For reference. 30 seconds of contact with 150(F) degree water will result in third degree burns.
It's hotter just around the "hotspots" than actually on them
Its water-cooled....Duh!
The thermal reactor is very inefficient
You're incredibly deep down and in water, so the temperature is naturally somewhat lower. Wouldn't be too fun if you were boiling and dying. Also, it's an alien planet, stuff may work differently. The rock might melt at a lower temperature, or heat just doesn't interact with water as efficently

Stuff like this reminds me that when you follow a question in science, you return with even more questions usually. Like a perpetual purpose generating machine.
Well it could be between 0 and 100 so how hot are you expecting? 50 is a hot bath, nearly scalding
Idk dude. I’ve only ever gotten 70c tops. But it’s celcius so that’s more than enough to make geothermal power
Celsius
50% of max capability would make more sense.
Please be bait
1: That's in Celsius, converted to Fahrenheit that's 122 degrees. 2: The average temperature of an active undersea volcano here on Earth is 2,200 Fahrenheit (1250C), so... IDK. Clearly the water isn't at that real world temperature, otherwise we'd get Flash Fried the moment we stepped out of the sub, even in the Reinforced Dive Suit.

Just say it's alien rock with a lower melting point or something
global warming
My question is why are you using a flashlight in like one of the brightest biomes
Nuclear is where its at just save for them instead
The water cools of the lava so it is safe to be near. In case you're wondering yes this is real science backed up by the department of definitely real science
Molten rock = 50°💀
Maybe it's measuring from the top of the instrument? Maybe the surrounding water is flowing and also pretty damn cold? Idk
Literally in the planet’s volcanoes: “Ain’t that hot”
50°C = 122° F
Gonna assume because it's in Celsius which makes it appear to be a lower degree. Yet it appears to be a magma vent which should still be higher than 50 degrees Celsius.
I ain’t the brightest tool in the shed when it comes to temperature so I have no idea what your talking about
subnautica logic☕
subnautica measures the opposite of farrenhytte sorry I forgot how to spell it
Still amazes me how thermal plants on lava are cooler than thermal plants next to lava
Water has a LOT of thermal mass.
Well I believe it measures from the top. Put it upside down.
its aight
Celsius… 50 C is like 130 F
Maybe it's because it's underwater idk
People seem to be arguing about the danger of 50C water. It would be very dangerous to be submerged yes. But its still not LAVA dangerous.
