Ice not melting in 50C liquid water.........

Just be thankful it doesn't melt fast. As @Kabrute says above it's 14 full tiles of water. If it melt all at once you'd have a real problem on your hands.

It actually is melting at once. It doesn't lose mass at all until its temperature reaches app. 0 - then it instantly turns into water and immediately cools it, which is not realistic (slime can do that with polluted O2, why ice can't?)

If you build ice sculptures the ice will melt 200x faster :p

Yes, this is the right answer. I found ice sculptures extremely convenient both for cooling and refilling the water pool - they'll melt immediately after they get built in water.

Even when built in air they melt ridiculously fast. Too fast to have any cooling effect on the air unless you leave the water there.

I actually wonder if they don't melt way too fast. In a sense that they pull the heat for their melting out of nowhere. I'll have to test it.

Edit: tested it, it behaves fine. The heat transfer is fast but beyond the fact that they lose 80% of their mass (which technically does add heat to the colony as they warm up) the thermodynamics are fine.

It is a kinda random number I pull out of my ass. But there is some things to consider Ice sculptures have a bigger surface area. And a hidden mass multiplier.

Does anyone know if i pump this 50C water in electrolyzier, will it heat up the oxygen and hydrogen produced?

No electrolyzer produce at fixed temp.

Edit. 

They produce at 70 or 75 degrees, you should pump geyser water with abysalite pipes.

As a building the sculpture acts as if it has one fifth of its mass.

It's a stupid question. Does the ice sculpture gets build with a specific temperature or does it get build at the same temp the ice you use is? 

And could you cool ice to -100°C and build supercooler statues?

Same temperature as the ice.

Here is a interesting thing that most players dont know :p

Mined chunk of ice will interact with a floor tile in vacuum. And the heat transfer is fast.

Only if the tile is hotter than the ice, I believe. I noticed such behavior for other things, too. For example airflow tile in vacuum will not exchange heat with anything except with hotter ambient element (liquid or tile) below it. I think it's par of the "heat propagates fast upwards" mechanic.

Fast test and it did cool down the ice to. But holy it fighting the cooling really hard. There is some heat deletion going on there 

EDIT: wait... Cold deletion..

EDIT: nope just a miss that it needed to heat up something.. So no heat deletion or cold deletion. And the rate seams to be about the same.

Okay, then it's probably some other mechanic. Interesting, thanks.
