Compacted Coal

Compacted Coal is an improved version of Coal made by combining it with Sulfur. It burns for 12 seconds and has a fuel value of 600 MJ, which is around 2.2 times higher than Coal (which has 270 MJ). It can be fed into a Coal Generator or vehicle for a much longer burn time. Compacted Coal is commonly used in alternate recipes involving fuels and coal related items. It can be unlocked after researching a Hard Drive and selecting the "Enriched Coal" option if available, and then unlocking the relevant milestones. It cannot currently be crafted in a Craft Bench and must be automated in an Assembler. It is used for making Turbofuel, which is about 3 times as efficient as normal fuel.
