Magma Cooling with Super Coolant Phase Convection.

[MustardWarrior]

So this is, I believe the best way to pull heat out of the magma biome.  Here is the idea, you vacuum and sweep out the oil biome, make a steam box with a diamond floor, dig away the abyssalite, exposing the magma, then pump in copious amounts of super coolant, dig out the igneous as it hardens at your leisure.  The idea is that the super coolant will condense at 437 degrees, is denser than magma and has a higher thermal conductivity than magma.  So what happens is the super coolant turns to gas and then gets cooled by the diamond wall, condenses, falls to the the bottom of the magma pool, turns to gas, bubbles up.  So until the steam below the turbines reaches 430 something degrees you see super coolant gas just flowing upward at a rapid speed and bubbling up from the bottom of the magma biome.  Once the steam heats up to 430 something degrees the rate of condensation slows and you get an equilibrium at about the phase change temperature. Unless you get >25kg super coolant gas pressure then the conductivity itself is high enough to heat the steam to a hotter temperature.

The test:  I built the device I described in test mode, no tempshift plates.  I put 1000kg of water into the steam box at like -3 degrees (it didn't freeze) I think I put in like 50-100 tons of super coolant at the very right of the map, I don't remember. I ended up with 15kg of super coolant gas in the tiles in the middle and like 32 kg at the right and 4kg at the left.  Within 5 cycles all of the ice cold water had boiled and all of the steam turbines were running.  I did a minimal amount of digging as huge amounts of super coolant got trapped.  I wish I had tested it with a more reasonable amount of super coolant.  But I regard this as a success though, the steam turbines are all constantly running at 430 something degrees and so this is destroying massive amounts of heat.  Also the right side of the map where you have 33kg of super coolant gas, the steam box is at 530 degrees so this means even without the convection, it is quite effective. 

Obviously if you want to conserve the heat for power purposes you will design it differently but the point remains, this super coolant gas convection technique is extremely effective at transferring heat into the steam box.

your build is similar what i been using , at top is ice for cooling down steam turbines,and bottom you use gas for transfer heat. i not used exactly same way tho by using the supercoolant but it sounds interesting

I just did more testing, replaced the magma and am using phosphorus instead of super coolant and while it isn't as good at destroying heat and doesn't sink to the bottom of the magma pool.  You can control the heat transfer by varying the amount of phosphorus.  Like if you only use 1 kg per tile, it won't fully power the generators but if you use 20 it does at least at high magma temperatures.  This is a better option if you want to get useful power out of it and obviously phosphorus is easier to obtain.  But yeah phosphorus has my steam box in the mid 200's which is ideal I guess like 210 would be perfect but this is very good.  The phosphorus boils at 280C.  I tried sulfur too and it's mid way in between the two, but I'm not sure why you would want to use sulfur.

If you want a 5x heat boost drop in phosphorite (SHC 0.15) which will vaporize into phosphorus (SHC 0.77).

Okay So I just did more testing and I now think I have the right answer.  You can control the heat transfer rate by controlling the amount of super coolant you put in.   500g per tile or about 1 ton total of super coolant should make it so that your steam turbines stay at about 210C so this way you aren't wasting electricity and also you still have the effect where it sinks to the bottom which actually results in the bottom of the magma being about 3 degrees cooler than the top which is really nice. 

Okay so granted the obsidian in the magma biome is going to kind of mess things up for you, but nevertheless, this seems like a really good solution.  You are getting the maximum power without being wasteful while also heating the biome from the bottom up and it's highly economical (well granted you are building across the entire map but per steam turbine, this is very little infrastructure.  500g of supercoolant per tile is the ticket.

Also I just tested it you can install a thermium gas pump just below the diamond floor.  I recommend adding some automation that adds supercoolant when it's too cool and pumps supercoolant out when it's too hot.

This is kind of a cool idea @MustardWarrior and I'm gonna run with it. Here's a prototype takes vaporizes phosphorite into phosphorus gas, then condenses it into liquid. It takes advantage of a game mechanic that teleports liquid condensed in a airflow tile. Improvements: pump the 275 degree phosphorus through a steam chamber and chill with an aquatuner to get the rest of the heat out. Add a drecko ranch as a source of phosphorite.

@Occam Blazer I mean if you're putting a set amount of phosphorus in as infrastructure to pull heat out of something that's one thing but just consuming  large quantities of phosphorite for some heat doesn't seem that good. Phosphorite is good for fertilizer, phosphorus is useless, I think a couple of shine bug variants can eat it but that's it.  It just seems kind of wasteful to me.

thats probably  best idea what i even seen atm from take the heat from magma, no need build tunneling and stuff as it cools bottom first

The advantage is a 5x heat multiplier. Phosphorite is renewable with dreckos so you can ranch as much as you need for fertilizer.

To be clear the phosphorus and sulfur do not fall to the bottom, super coolant is the only one that will.  But as my previous post indicates, you don't even need very much of it 500g per tile works, so maybe like a ton or so and you're good so the fact that you have to use super coolant isn't a big deal.

orfcouse as super coolant needs more heat for turn into gas

[gabberworld]

for me it looks like bug tho because magma liquid is 2x heavier than super coolant, unless if its some chemical reaction that it drills tho heavier material
