 ## Fuel Economy
 The closer you are to the perfect ratio of [color=#a4885c]1:2[/color] (1 AME core to 2 fuel rate) the more efficient you'll be. You're cutting fuel efficiency to [color=#a4885c]50% and less[/color] if you're using more cores, but less fuel injection rate.
 For an example [color=#76db91]3 core and 6 fuel rate[/color] will generate [color=#76db91]240kW[/color], while [color=#f0684d]8 core 8 fuel rate[/color] will generate [color=#f0684d]160kW[/color]. Generating 80kW less while spending 2 more fuel each injection.

+## Upgrading the AME
+
+You can generally only upgrade the AME by getting more cores, which can be done by ordering more AME packages from [color=#a4885c]cargo[/color].

+# Gas mixes and Burn chambers
+In the event you finish all the tasks at hand, you can make some extra power or money by creating new chemical gasses.
+
+##Tritium
+Tritium is a clear, green gas that is highly flammable, radioactive, and combusts when in contact with oxygen making it very helpful when running the [color=#a4885c]TEG.[/color]
+It can be made by burning 1% Plasma and 96% or more Oxygen in the Burn Chamber. You can extract this gas through scrubbers.

+##Frezon
+Frezon is a bluish-green gas that is very complex and very dangerous. To obtain frezon, you must mix Tritium, Oxygen, and Nitrogen in a 70K room to start the reaction, as well as prevent the Tritium from combusting with the oxygen.

+It is critical to understand that a frezon leak can devastate the station, causing a wintery hell filled with itchy sweaters and cold burns. Frezon is very cold, and can freeze the station to death if even a few moles get out, so make sure that you lock your canisters or just move your Frezon straight into a storage room.

 ## Reference Sheet
 - Standard atmospheric mix is [color=#a4885c]78% N2 and 22% O2 at 101.24kPa.[/color]
 - Gas obeys real math. You can use the equation PV = nRT (Pressure kPa * Volume L = Moles * R * Temperature K) to derive information you might need to know about a gas. R is approximately 8.31446
