Have you ever wondered which element is the best fuel? Which element is ideal for your engine or rocket? Have you ever wanted to know which element is more efficient: NITR or GUN? This article will present different fuels and their statistics. This page also includes combinations of elements. There are the most obvious and most popular types of materials that can power generators or can be used in models of rockets. This comparison shows different possibilities of fuel, their advantages and disadvantages, and also few numbers that describe its power. Everything is shown in the table below.


A fuel is any material that can be made to react with other substances so that it releases chemical or nuclear energy as heat or to be used for work. In TPT, a fuel is any element that can generate energy (mostly heat), which can be used to power different machines and simulations. Fuel changes its state due to chemical or nuclear reactions and releases portions of energy at the expense of losing its internal power.

General types of fuel

We can distinguish the following types of fuel:

Solid fuel

  • Powder fuel like GUN, FSEP, BCOL
  • Real solid fuel COAL, TNT, WOOD

Liquid fuel

  • Conventional liquid fuel like OIL, NITR, DESL
  • Special liquid fuel like LOXY, LBRD, ACID


  • Typical gasses like GAS, HYGN, OXYG
  • Other gasses like NBLE, CAUS, VRSG

Nuclear fuel

  • Solid nuclear like URAN, PLUT, POLO
  • Liquid nuclear fuel like DEUT, ISOZ

Other elements

  • Other elements like VIBR, SING, PHOT

Elements combinations

  • Mixed elements, which create new particles like HYGN + OXYG
  • Mixed elements to get better burning like IGNC layer + BCOL layer

How to examine and describe fuel

There will be information on how @docRoboRobert measured different types of fuel. Actually, this part is under construction.

Testing chamber

Testing chamber.png

This is an apparatus which allows to measure properties of different fuel types. The first box should be filled with testing material and ignited. This box can be used to log temperature data and measure pressure. The second box is used to measure how much energy (heat) is transferred to other materials and how effectively it can conduct heat. 3rd container is used to measure the burning time and measure temperature for elements, which can't be properly ignited in 1st box (like OIL). The last machine is rocket engine test. This can be used to measure how effective the element is as rocket fuel and how much thrust it can generate.

Useful formulas

Here are some formulas that can be used to measure effectiveness and power of different fuel types.

Burning time It's how long (in frames) you need to wait until all fuel is burned out. Note that in some fuel types, burning time depends on where the fuel was ignited from. For example: GUN burns instantly if it's ignited from the bottom.

Fuel effectiveness Can be measured using this formula:

(average burning temperature x average pressure) + (Δ water temperature/3)

Average pressure is pressure measured after few frames after ignition or average pressure measured during burning process (if fuel burns long enough and doesn't generate pressure instantly) Basicly, more pressure = more energy has been released = better effectiveness.

Δ water temp. is the difference between temperature of water after burning time and temp. before ignition and divided by 3 due to there's three times more water than fuel in testing chamber.

After that, the number have to be divided by 100 to get smaller number. (eU is energy unit)

Released energy can be measured using this formula:

Δ temperature x average pressure + amount of additional particles

Average pressure is pressure measured after few frames after ignition or average pressure measured during burning process (if fuel burns long enough and doesn't generate pressure instantly)

Δ temperature is difference between temperature before ignition and average burning temperature.

Amount of additional particles is a number of extra particles released during burning (total released particles - number particles of fuel before ignition).

After that, the number have to be divided by 100 to get smaller number. (PEU is Powder Energy Unit)

Efficiency as rocket fuel It's number of pixels that released particles (mostly fire) travelled in 10 frames. Basically, longer distance = better thrust = better efficiency of rocket fuel.

Efficiency have to be measured when released particles (mostly fire) are half-way out from testing tube (last testing chamber).

Gas, solid, and other fuels that can't flow should be tested in bottom tube.

Advantages & disadvantages are described from observations and analizing different saves. They're the most common thoughts of others users.

Notes are the special/additional informations about fuel that might be helpfull.

Table of fuel types

There will be the table with different fuel types, their statistics, advantages and disadvantages. Actually, this part is under construction.

Material Fuel type Temperature Pressure Burning time (frames) Fuel effectiveness Released energy Efficiency as rocket fuel Advantages Disadvantages Notes
GUN Powder 722C 4.00 1 - 20 29,45 eU 28,89 PEU 26 eU Can't melt most of materials. Quite light particles might not flow very well. Sometimes used in solid fuel rockets.
NITR Liquid 922C 4.00 1 - 20 37,62 eU 36 PEU 26 eU Liquid element is good rocket fuel

if you use it with PIPE.

Might explode easily if isn't isolated. Commonly used as boost in engines.
C-4 Solid 922C 4.00 1 - 20 37,62 eU 36 PEU 24 eU Can be easily ignited by spark or pressure. Not good for engines (can't flow) and rockets (weak thrust). Releases the same amount of energy as NITR. Rarely used as fuel.
RBDM Solid 922C 4.06 1 - 20 38,18 eU 36,54 PEU 24 eU Can be ignited by water. Rarely used as fuel. Similar to C-4. Can easily melt into LRBD, which is more often used as a liquid fuel.
