Why do we need an extra element, when we can just apply more rules to existing ones, for example, steam reforming. Oil is heated to make gas (tpt methane basically) which in the real world reacts with steam to give hydrogen. there is a positive enthalpy ch though.ange i.e. it is endothermic, not by much

Why do we need an extra element

I support that much. There is quite literally no point here other than to have some form of endothermic reaction. Is there even an element suggestion happening here, or what?

EDIT: Okay. nvm. There is an element suggestion. But rockets that spew out cold gas? Like how MORT gives off CO2? Also it seems as though there will be no purpose to these elements other than an endothermic reaction.

Whats so exciting about endothermic reactions anyway? I understand EXOthermic reactions, because that means fire and explosions. Endothermic elements would cause what? All the water in a save to freeze?

That is true, I hadnt thought about that,

 Endothermic rections are both vitally important and very cool - try looking up some of the ore important examples. MORT gives off SMKE at about 300 degrees c. Simple rcs thrusters that rely on expelling a compressed gas have very cold exhaust. Also you should really understand the difference between endothermix and exothermic reactions.

 Point taken, but the world of sub zero temperatures is not even complete for existing elements, let alone new reactants; look at the lack of liquid hydrogen or NOBLE (liquid heilium). It would be very cool to see the complete set- liquid helium in superfluid phase will actually creep out of its container and continue to spread out. teh best element to introduce would be gaseous nitrogen:

reacts with hydrogen to make ammonia (Haber)

makes the LN2 more realistic

ammonia is a coolant in its own right (experimental)

ammonia + caustic gas would make Ammonium chloride powder

this salt then reacts with water endothermically (why they use urea in instant cold packs)

all this comes from nitrogen gas reacting with existing elements- no editing, just include the reactions under the new substances.

And yes I do realise this goes against my previous statement.
