A TTV does not explode on its own: it only connects two tanks. The tanks themselves explode.

The explosion depends entirely on how high the pressure is able to rise inside a tank before it destroys itself or leaks out. There are two main ways to do this:

== Reactionless Explosions ==
=== Principles ===
Reactionless explosions are more often than not the easiest to produce. They work by letting a hot gas mixture heat up another gas mixture.

In order to do this effectively, we need to do two things:
# Put as much energy as possible to the system.
#: The more energy we can fit into the first tank, the bigger the explosion.
# Make the resultant gas mixture extremely easy to heat up while packing as many moles as possible, I.E. low resultant specific heat capacity.
#: The lower we can push the resultant gas mixture down, the bigger the explosion.

=== Execution ===
We need a hot gas with high specific heat capacity, and a cold gas with low heat capacity. The former will give more energy, while the latter will drive the resultant heat capacity down and allow more moles to be involved.

*The easiest gas to obtain with a reasonably high heat capacity is [[File:Plasma_Canister.png]] Plasma.
*The easiest gas to obtain with a reasonably low heat capacity is [[File:N2_Canister.png]] Nitrogen or [[File:O2_Canister.png]] Oxygen. Though oxygen also burns with plasma, further adding to it's pressure. Read more on reaction explosions [[#Reaction-Based Explosions|here]]

Procure both canisters and heat the plasma and cool the nitrogen/oxygen using a [[File:Freezer.gif]] thermomachine. Simply wrench the canisters to the connector port and adjust the thermomachine directly.


If a thermomachine is not available. you may <b>relocate</b> a thermomachine from the ordnance chambers or <b>build</b> a new one.

* To do the former, [[File:Screwdriver_tool.png]] <b>screwdriver</b> the thermomachine, and [[File:Wrench.png]] <b>right-click with a wrench</b> to unwrench it. <b>Left-click with a wrench</b> to rotate it if necessary.
* To do the latter, build a machine frame, procure the circuit and necessary components, and build the thermomachine. Read more on construction [[Machines#Machine Construction Steps|here]]

You can flush a thermomachine's air contents by reconstructing it too!

After you procured the thermomachine, connect a [[File:Atmos Connector.png]] connector port to it's input node using a [[File:Rpd.png]] RPD.

== Reaction-Based Explosions ==
Another method to make explosions is to have exothermic reactions occur inside them. The reactions will drive the temperature up, which in turn drives the pressure up, causing an explosion.

To generate very big theoretical explosions, you will need reactions, especially the very energetic ones like Tritium Combustion and Hyper-Noblium Formation. Both requires tritium which you should already have, if you don't read [[#Tritium Synthesis|this]].

=== Production of a Tritium Bomb ===

==== Principles ====
Tritium combustion have several main properties. Upon the opening of a valve, the tanks will allow <b>exactly two</b> reaction ticks before exploding.
We also know that tritium combustion:
# Needs to happen above 100 Celcius.
# Needs 10 times the oxygen as tritium for the highest energetic burn.
# Consumes half as much oxygen than tritium burnt.
# Burns tritium at 5% of the oxygen each tick, up to half of the tritium per tick.
# Factor three and four means the number of oxygen burnt each tick 2.5% of the oxygen each tick, up to 25% of the oxygen each tick.

All of these factors have led that a 12.85% tritium 87.15% oxygen mixture to be an efficient choice, due to the unique interaction between the reaction ticks and the properties of the tritium burn itself.

In essence, the 12.85% tritium 87.15% oxygen mixture which contains more than 6 times oxygen as Tritium, allowing the burn to happen twice near peak efficiency, with as high reaction rate as one can get.

The first tick will consume around a third of the tritium and five percent of the oxygen. Paving the way for the second tick to also be energetic.

The second tick will consume half of the remaining tritium, leaving a third of the initial tritium left. Letting us make the biggest, baddest bomb possible.

A lower temperature for the tritium-oxygen mix means a higher reaction rate for the two ticks that are allotted to us, but also means a higher energy requirement to exceed the 100 Celcius threshold for the reaction to occur. Keep this in mind when you are upgrading your mix.

==== Execution ====
We want a 87.15% 12.85% mix of Oxygen and Tritium (in that order) in the payload tank.

A very common temperature to aim for is 43 Kelvins at 2533 kPa, which requires a hot plasma mix of around 800 Kelvins to heat the resultant up to 373.15 Kelvins. A hotter plasma mix is very often desirable here, since hotter plasma means a lower resultant heat capacity, which means a larger temperature increase, which means a larger explosion.

If you wish to follow this recipe, for the cold tank simply:
#Pump up to 325.5 kPa of 43.15 Kelvin tritium into a tank.
#Pump up to 2533 kPa of 43.15 Kelvin oxygen into a tank.
#Analyzer the resulting tank and make sure oxygen is above 65.52%

=== Production of a Hyper-Nob Bomb ===

==== Principles ====
Hyper-Nob bombs are made using their formation reaction, which when unmoderated by BZ releases a lot of energy. This formation involves [[File:N2_Canister.png]] Nitrogen and also [[File:Tritium.png]] Tritium

There are a few notable properties about this reaction:
# Can only occur below 15 Kelvins
# Consumes nitrogen at twice the rate of tritium. Moderated by BZ but we will not include BZ in this mix at all so it's safe to ignore.
# The consumption rate for Nitrogen is equal to 10% of the pooled Nitrogen + Tritium mole count. Tritium consumption is half of this.

Since this reaction occurs on very low temperatures and is incredibly exothermic, <b> it will only happen on one tick</b>. This means we will need to make the first tick occur with as much reaction rate as we can.

If we pay attention to how the reaction rate works with the mole consumption, we can see that we will not need to fill the payload with 50% Tritium as this is incredibly wasteful. It is possible to pad out the reaction with Nitrogen to drive the reaction rate high enough so that all of our tritium is consumed, netting us the most tritium-efficient Hyper-Nob burn possible.

This ratio works out to be 95-5 Nitrogen-Tritium. The burn will consume Nitrogen equal to 10% of the total mole count and more importantly Tritium equal to 5% of the total mole count, leaving us with a full Tritium consumption. Most of the Nitrogen will be left unreacted, but the station has an abundance of Nitrogen so it should be relatively easy to replenish it.

==== Execution ====
For this, we will need a significant amount of cooled [[File:N2_Canister.png]] Nitrogen and also [[File:Tritium.png]] Tritium. 

Nitrogen is already available, so grab a canister from the gas storage and cool it down to below 15 Kelvins on an upgraded [[File:Freezer.gif]] freezer (Tier 3 parts or better)

Tritium on the other hand needs to be made first, so read up on [[#Tritium Synthesis|Tritium Synthesis]] if you haven't. You will also need to cool it down to below 15 Kelvins using an upgraded freezer.

:<b>Optional:</b> A padding gas like [[File:CO2_Canister.png]] Carbon Dioxide or [[File:O2_Canister.png]] Oxygen can also be used to have more moles in the mix and thus more pressure once the bomb reacts, producing a bigger explosion. Just make sure they are also cooled to below 15 Kelvins or else they might make the resultant gas mixture too hot to react.

The target mixture is 95-5 Nitrogen-Tritium, we cannot combine both of them inside a tank like in the tritium bomb cold mix, since they will start reacting and explode. So we need to put them in separate tanks. To do this simply:
# Pump up to 2533 kPa of 13 Kelvin Nitrogen to a tank.
# Pump up to 127 kPa of 13 Kelvin Tritium to another tank.
# (Optional) Brim the Tritium tank with 13 Kelvin Carbon Dioxide or Oxygen.
# Analyzer both of the tanks and make sure both of them are below 15 Kelvins and the Nitrogen mole count is about 19 times the Tritium.

<b>Extra note:</b> Unlike the tritium burn reaction, messing up the mole count and the ratio of this mixture is not as debilitating. Your bomb might still be able to explode even if you have a little too much Nitrogen or Tritium, as long as the temperature is below 15 Kelvins.
