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.
The tech for Charcoal is not nessasary for the Soil miner to collect peat and make it into charcoal.
