Fridge for materials being brought into the base or already possible contraptions


Recommended Posts

The volcanos spewing out molten iron/copper/gold output said metal at 2500 C (iron & copper) or 500 C (gold) per this post.

I ignore for the sake of this discussion that you'd need to cool the liquid to around 1500 C for it to be mine-able.
This is obviously a lot of thermal energy that cannot be brought into the base carelessly.

I see three solutions to the problem of handling these super hot materials, with their own pros and cons:

  1. Keep it outside of the base in external storage facilities

    Ignoring the metal's thermal energy may not be the wisest choice because you might keep in such a storage facility other materials as well, which could possibly change state due to the high temperatures. Even if the metal cools down a bit during its relocation, let's say to 1000 C, what if you want to use it for a building inside the base? A building made out of such tremendously hot metal would increase temperature base-wide.
     
  2. Implement a fridge for materials, which some means of determining when it is safe to move the metal into the base

    Ore scrubber is a machine that is mostly used in the corridors leading in/out of the base, so that dupes brining in polluted materials can clean them. What if the same could be done to hot materials? It may cost energy or a coolant like water input, but it would ensure we get a relatively cooled metal to be brought in.
    It could be done in two ways:
    - the fridge would just work as an intermediate storage, which would require a thermal sensor to determine if the temperature has dropped enough before marking content as "permissible".
    - the fridge would work exactly like ore scrubber, using coolant and energy to rapidly cool the metal in just a few seconds, so that dupe can wait a few seconds and pick it up for delivery.
     
  3. Use a different method already available in the game
    Here I really rely on your solutions because to me there is no way, without micro-managing each material for sweep, to implement a self-automated chamber for cooling metals that moves the cooled materials into the base.
    Do you have any ideas?

What about cooling them significantly before mining? Stick a steam turbine over the collection pool, use automation to determine when they're too cool to run it, then mine it out.

EDIT: To be clear, this would involve generating the steam with polluted water, which should provide fast cooling

I was thinking of using a channel to allow the liquid to flow in to a chamber. Then opening an airlock above which will dump a vat of cold liquid on it.

I imagine I'd need to experiment with masses. If steam is a bi product I would try putting a steam generator above the chamber too.

I guess oil might be better for the natural gas. There's a few options for the coolant with beneficial side effects.

That is a really interesting idea! The cooper and iron volcano can potentially support at least one steam turbine and we have enough ways of producing polluted water not to be frugal with it. You achieve free steam which can potentially be condensed to clean water, free energy and metal potentially cooled to 100 C or so. I'm wondering exactly how much water we'd need to do this.

Dripping oil on metal could also work, but the question is whether it would yield more net power than steam.

I think some earlier forum-goers determined that, in terms of power generation, boiling oil is far superior. However, there is no heat loss (as far as I'm aware), while I believe that the steam turbine does delete some. Needs experimentation, but it looks like it might be a trade-off between power and cooling.

dupe AI should really work here, especially if they can analyze a materials temp
or if dev add a "material temperature" setting on the compactor, lets say a compactor is allowed only to store items with temperature below 30c. now that would be really helpful especially in maintaining base temp

compactors have capacity slider on top, which you can control its maximum capacity, and i dont even use it (do you use it?) 
if that slider is not really useful, why not just rip it off and replace it with a temperature slider for ores

One interesting thing that less known is that if the material is over 45 C to build a structure it will always be 45 C when the building is done.

So if you build something with 1000 C when it is done built it will be 45 C.

Compactors with 1000kg of ice inside melt a LOT faster than ones with 20000kg.

That, and 1000 kilograms of water being added to your liquid pool is way more manageable than 20000 kilograms.
