Rocket Engines give you their max output in kN with this you can calculate what they can reasonably carry into orbit depending on the planet or moon you are on. Force = Mass * Acceleration. Acceleration is equal to the planet's gravity, Mass is given in kg per part of the rocket, and Force is kN. If your thrust force listed below is less than the weight of the rocket in kN then you will not even take off. It is better to have a thrust much higher than the weight of the rocket or else you risk running out of fuel on launch and on landing.

Liquid propellants bring greater efficiencies. Using Nitrous Oxide as oxidizer provides excessive thrust values. Keep in mind that N2O fuel mix is 1.9375 times heavier at same moles, or 2.15 times heavier at same volume, while thrust boost is around 1.5-1.7. Engine efficiency determines "bonus" thrust multiplier, meaning engine with higher efficiency will give more thrust consuming same amount of fuel. Thus using liquid engines is more favorable if one can cool fuel down, moreover Pressure Fed Engines consume fuel inversely proportional to its temperature. On the other hand if [[Volatiles]] and [[Oxygen]] are in excess (e.g. farm on [[Vulcan]]) is may be much easier to opt for Pressure Fed Gas Engine. It will provide ~40kN at 20°C.

== Description ==
To complete construction, you must weld 5 Steel Sheets onto the kit after it has been placed.

The advanced composter creates [[Fertilizer]] out of organic matter. It accepts food, [[Decayed food]] or [[Biomass]]. It requires water and power to operate, accelerating the natural composting process.

When processing, it releases nitrogen and volatiles, as well as a small amount of heat

== Reaction ==

While converting 3 [[Decayed food]] to 1 [[Fertilizer]] the composter will consume 20 moles of [[water]] and release 50 moles of [[Nitrogen]] and 50 moles of [[Volatiles]].

As of version 0.2.5474, the way that the Advanced Composter works is as follows:

Internally, it stores the number of Food, Decayed Food, and Biomass inserted. When it finishes the current processing cycle, it will take the ratio of the three to determine how many of each to remove. It will always remove a total of 3 items. Then, it determines the output Cycles, Harvest Boost, and Growth Speed Boost values.

<pre>
Cycles = 2 + (Biomass Ratio * 5)
Harvest Boost = 1 + (Food Ratio * 1.5)
Growth Speed Boost = 1 + (Decayed Food Ratio * 0.25)

</pre>

After the output [[Fertilizer]] is used on a [[Hydroponic Tray]] or [[Hydroponic Station]], any seeds planted will have their Harvest Quantities and Seed Quantities set to the base yield plus the rounded Harvest Boost modifier. The Growth Speed Boost is applied as well, and is a multiplier for how fast the plant will grow. Every time an item is planted, the Cycles decrease by 1, and then if it is less than 1, it is set to 0. This means if the Cycle count is 1.3333333, after planting one item it will go to 0, wiping the fertilizer from the planter.
