Wood or Charcoal
Charcoal has a net fuel efficiency that is three times higher than regular wood, and is generally considered the better choice.
- First level charcoal clamps converts wood into charcoal at a 4:3 ratio.
- First level foundry uses 4 times more wood than charcoal in its production.
- The efficiency of charcoal divided by the wood to charcoal ration gives us (4/(4/3)) = 3.
- This gives us an overall efficiency that is 3 times that of wood.
Charcoal can also be made by the Soil miner.
The tech for Charcoal is not nessasary for the Soil miner to collect peat and make it into charcoal.
