Chemical reactor

A chemical reactor is a machine that can be used to cause chemical reactions between various items, which leads to other items being created, or energy to be produced (in which case it is a "chemical power plant").

To construct a chemical reactor you need some tin shell, and a 'chemical reactor' interface block. Build a 5x5x5 hollow cube out of tin shell (including a redstone input at the very least, and possibly fluid and energy input and outputs too), and on the 'front' side (whichever one you decide should be the front), in the very center, you will place a chemical reactor interface after all other blocks were placed. The reactor will turn on as soon as there is signal on the redstone input.

Reactions
There are different types of reactions that can occur - they all require reactants and a specific temperature - sometimes higher temperature speeds them up, or if it's too high, it can also hinder it and produce garbage or side effects. Some reactions also have catalysts. The full list of chemical reactions ("recipies") is displayed by CraftGuide if it is available.

Heating and cooling
To heat up a chemical reactor, you can either use a capsule containing lava, or natural gas. In both cases, if you have a fluid cable connected to the reactor, which is also connected to a source of lava or natural gas, then lava/gas capsules in the reactor will automatically refill. You can also cool a reactor using water capsules.

Lava can only heat up the reactor to a limited temperature, so not all reactions are possible. Natural gas can make unlimited temperature, so inserting multiple gas capsules generates higher temperature.

When the maximum temperature is reached (the thermometer gets to the top), the reactor explodes, but is is hard to achieve this effect in practice.

When the reactor is heated up, you cannot take items out of it (because it would hurt your hands), unless you wear a safety suit.

Power Generation (Chemical Power Plant)
To generate power heat up the reactor (preferably with natural gas), then put in some water and Turbines. Connect the energy output of the reactor, using Energy cables, to an Accumulator and start up the reactor - the accumulator will start filling up with energy.
