Hot springs circumvent physics #53276

Open NetSysFire opened 2 years ago

NetSysFire commented 2 years ago

Describe the bug

The temperature in the middle of the hot spring is roughly 160°C. Water boils at 100°C.

The resulting water will be water (hot) and not clean water (hot). I am aware that hot spring water does contain things you do not want to drink and hot spring water should probably be its own thing.

Steps to reproduce

  1. Find or spawn a hot spring.
  2. Teleport into the middle of it and make sure you can measure the temperature via e.g a divers watch.
  3. The temperature will be around 160°C. The maximum I got was 163°C.

Expected behavior

Lower temperature. I do suspect the high temperature is actually a bug: If you stand near a single tile of hot spring water, the increase in temperature will be low. However if there is more than one tile of it nearby, the temperature will rise potentially exponentially since it "stacks".

Does the game have any means of handling enthalpy of fusion or vapourisation? If not the higher temperature might be an acceptable (probably low-ball) representation of the additional heat in steam. Geysers are nasty to fall into!

Talking about the water cleansing behavior, what do you think about replacing hot springs water with mineral water?

NetSysFire commented 2 years ago

If you mean the fancy sparkly water, I do not think this would fit. See https://en.wikipedia.org/wiki/Hot_spring#Chemistry, I mean it is technically mineral water but it can (and usually will) contain compounds that are toxic to ingest. Also maybe some bacteria adapted to living in hot springs. See https://en.wikipedia.org/wiki/Hot_spring#Precautions for that

Well, the closest already existing thing that could be used is salt water, even if it's not technically true.

I agree, salt water would be a possible solution without adding anything new.
