Gascraft
Gases. They are a major danger to miners in the real world, and sometimes a great natural resource if it is the right kind of gas. Seeing as how we have to spend some time at least partially underground, lets see if we can make this a little more interesting than it is now..
I know it has been suggested, suggested, and suggested again, but I want to make a super-thread of sorts for it.
Note I will be using "damp," terms, names for gases used by British miners in the older days. While I could use the scientific names for them, they seem lame and out of place for the game.
0. General Gas Behavior
http://en.wikipedia.org/wiki/Gas
Movement: All gases will have the same general movement. Movement will essentially be like water, but upwards. Gas will always spawn in caves. Gas is unbreathable, and therefore you can drown from entering a cloud of gas. They are usually found in pockets in the ceiling, in small patches, though they will vent from the floor, making them a hazard, such as lava.
1. Blackdamp
http://en.wikipedia.org/wiki/Blackdamp
A mixture of unbreathable gases, it happens when coal is exposed to oxygen for a time. It would act like water, except flowing upwards and such. When entering a cloud of it, your oxygen bubbles will appear, and as with water, if you run out, you can, "drown." Torches cannot be placed in the clouds, as there is no oxygen to burn. Found in mines and caves, always in the presence of exposed coal.
Breakdown:
-The gas is a relatively easy to avoid taking harm from, and eliminate
-Acts like a normal gas, as described in part 0
-While unseen in real life, the clouds would be semi-transparent, making the area its in slightly darker.
-Found in mines and caves, always in the presence of exposed coal.
Uses: It can be used for a fire retardent system, if you have a wooden floor. If the floor catches fire, and you have gas under your floors, it will smother the fires. Other than that, no practical uses.
2. Firedamp
http://en.wikipedia.org/wiki/Firedamp
A name given to a mixture of explosive gases, mostly methane, that again usually is found near coal. It acts like a gas, as described in part 0. But instead of being like water, it acts a lot more like TNT, albeit hitting it will not cause it to explode, and at half power. When torches are placed into a cloud of it, each gas block will then act like a block of TNT, and then proceed to explode, most likely killing you and destroying a large chunk of rock. When mining in a cloud (which you shouldn't do as you can still drown), there a 10% chance when mining rock, you will set off the cloud.
Breakdown:
-The gas is again, easy to avoid taking harm from, and eliminate
-Acts like a normal gas, as described in part 0
-While unseen in real life, the clouds would be semi-transparent, and ever so slightly red, as a warning/indication.
-When in contact with fire/torches, or having stone mined within the cloud (10% chance), it will explode, each gas block acting like TNT, though at half power.
Uses: It can be used as cheap, never ending TNT, useful for clearing out a tunnel, or as a one time trap.
3. Afterdamp
http://en.wikipedia.org/wiki/Afterdamp
A name given to a mixture of toxic gases. It acts like a conventional gas, as usual. Instead of being like water, as described in Blackdamp, but rather acts like fire. Entering the cloud will cause you to take damage as if you were on fire. Leaving the cloud is the only way to escape death (Or by wearing an oxygen mask[Described later]). Torches cannot be placed within the cloud.
Breakdown:
-The gas is harder to avoid, and take care of, as it damages you on head contact.
-Acts like a normal gas
-While unseen in real life, the clouds would be semi-transparent, and ever so slightly green, as a warning/indication.
-Causes damage on contact, acting like fire. Leaving the cloud will stop damage.
Uses: Its just a hazard, and is useful for traps.
4. Natural Gas
http://en.wikipedia....iki/Natural_gas
Ah, natural gas, finally a gas that is helpful. It is a conventional gas, though it is flammable, though not explosive. Having it in contact with a torch/flame will set the gas blocks on fire, and having it all go to waste. What can you use it for? A supremely long lasting furnace fuel, and probably other things that I haven't thought of.
Breakdown:
-The gas is easy to avoid and eliminate if you wish to do so.
-Acts like a normal gas
-While unseen in real life, the clouds would be semi-transparent, and ever so slightly purple, as an indication
-Flammable, but not explosive
-Can be harvested, and used for 320 uses in a furnace.
Uses: Furnace fuel
5. Smoke
http://en.wikipedia.org/wiki/Smoke
Smoke will be a product of burning blocks. It will act a lot like afterdamp, though its damage rate is way slower than the actual thing. Other than that, its pretty much a normal gas (While not really being a gas). It should also be noted that Netherstone could emit smoke, but its debatable.
Uses: Its smoke. It also cannot be harvested.
6. Ascendium
Its a gas of my own making, just a little something interesting
Anyways, its a magical gas that is many, many times lighter than air, in fact, its lifting power is strong enough to lift you! Its only relation to gases is that it goes upward. You can breathe in it, torches can be used in them, and it goes up at a rate superior to anything else. The patches are also rare as diamond.
Breakdown:
-Not a typical gas, going up is it's only relation
-You can breathe in it, torches can be used in it, and you can jump into the cloud to get a lift!
-Rare as diamond, the gas patches are
Uses: Elevators, and something to fling you up many blocks into the air

This isn't one you'd find while mining, as it must be produced. In real life, methane and ammonia are heated with oxygen to produce cyanide. In minecraft, you just need to place a canister of the explosive gas in a furnace. Makes one "source block" of cyanide.
Breakdown:
-Cyanide is extremely poisonous, making it an almost instant death
-Cyanide will be a white-transparent cloud
Uses: Traps
8. Gas Harvesting
Since I couldn't find any small scale, one man usable gas harvesting tool, I'll just come up with one.
Introducing.. the gas bucket/cylinder!
Yes, you can use it to collect any* of the gases, including the explosive gas.
9. Oxygen Mask/Oxygen Tank
I'll just borrow some designs from my Oceancraft thread then..
Oxygen Mask:
[]
Oxygen Tank:
Have these on when entering a cloud and you won't drown/get poisoned by them.
So yeah. Questions, comments, concerns?
*Excludes smoke
