The Carbon Extractor is a construct that crafts Wood out of thin air (technically carbon dioxide), by spinning a turn-handle. This construct is especially useful in lower elevations where no Roots exist. It also has a by-product which is Oxygen, increasing the Population-cap in lower maps (not yet implemented).
The Carbon Extractor is crafted by an engineer using the Anvil.
The Carbon Extractor is unlocked through the Carbon Extractor technology, in the Crafting branch.
The Carbon Extractor enables the crafting of Wood.
