We need more realistic interactions

[palpita]

First of all, I'm sorry, I didn't read even a single thread yet and I don't know what has been suggested yet, just bringing up the ideas I've got.

Okay so... where the f water disappears when burning hydrogen?? I think this was mentioned already, as everyone knows this simple chemical reaction, but please, don't make stuff disappear, I love this game, it's gas physics, but water not being created from this reaction is ********, doesn't have to be a lot, just a few drops, please? I understand that it's for balance reasons, but... We still use something like coal or our dupes to generate power for electrolyzers, that generate hydrogen, oxygen and use up WATER, so no, it wouldn't really be free infinite cycle, I don't know, make it emit a lot more heat, that way we would need to play around that and it wouldn't be so easy.

So, you mine out copper ore, iron ore, sandstone, etc... But what then? You can't do anything but keep it there (aside from using for machines and tiles). You can't even rebuild it somewhere else, could that please be an option? If I understand how building is implemented, it could easily be done with adding extra "natural tile" tile to base, and by selecting material you want to build that tile out of, would basically rebuild that tile... Umm, why not? The only problem I see is slime would be abused (dig it out, bring it to puft farm to generate more contaminated oxygen for it by rebuilding it).
Maybe same could be done with regular tiles? They could have texture based on what material they were built out of? It's nothing important but it would be neat.

Contaminated water. Now... It just stays on top of normal water and nothing happens. Maybe that mechanic could be redone to "all water is now the same", but it contains x grams of contaminants and contaminants itselves would be "liquid" on it's own inside water slowly spreading out once contaminants get inside? Based on comtanination level, more sand would get used up in water purifier, (idk if water purifier uses sand or if fresh water can be pumped through it yet), but sand wouldn't be used up at all if it was fresh water and stuff. Basically we would filter out A LOT of water, just to remove a very small portion of contaminants, but it's "our fault" it got contaminated, but sand used up would be equal to the same thing as if one block of contaminated water got into fresh water body in current game state, not that much really. But this is still linked to my next idea...

Crushing hard materials to create artificial sand? It's so scarce right now, I think it really should be generated outside the starting point, or be semi renewable, as in, you would have it as long as there's stone to mine. Doesn't necessarily need to be sand, could be gravel which can be put into same machine, yet linking back to previous idea, purifies water a bit less, so you have to run through it multiple times. Anything to survive, right?
