Hydraulic Platform

This is no less than an actual elevator. Place the 4 blocks down like a square and the platform will form. You need to place 4 more either above or below in the exact same position. Stand on the platform and it will light up green. Press [Jump] to go up to the next patform, or [Crouch] to go down a floor. It won't work if the destination platform is too far away (like 20 blocks away).

Water Electrolyzer

Uses a lot of power to seperate Water into Oxygen and Hydrogen. Insert Water by using either a fluid container or fluid pipe, then use Fluid Pipe to extract the Oxygen and Hydrogen. Must be connected to a Tier-2 power network.

Methane Synthesizer

Uses a source of Hydrogen and Carbon to make Methane Gas. You can get Hydrogen from the Water Electrolyzer.

There are 2 ways to get Carbon. Place Coal in a crafting grid to get back Fragmented Carbon, and use that as a Carbon source. Or, if you're on the surface of Mars, you can place an Atmospheric Valve in the Carbon slot to get Carbon from the atmosphere. This machine uses a lot of power and must be connected to a Tier-2 power grid.

Gas Liquefier

Converts various gases into their liquid form. This machine is primarily used to obtain Fuel from Methane Gas. This machine uses a lot of power and must be connected to a Tier-2 power system.
