A Black Smoker, also known as a raw material deposit for the Metal Converter, is an Underwater phenomenon which happens on most underwater plateaus. The Black Smoker will "smoke" Black material out into the sea, similar to an oil spill, but it doesn't cause any damage. It will cease activity after a certain period of time after the player has attained Researchers in a city. Normally the countdown is about 10 hours, but it can also be up to 20 hours. Once the black smoker ceases activity, it will leave behind a raw material deposit which can be mined in unlimited amounts with a Metal Converter. When the black smoker ceases its "smoking", one of the following fertilities can appear: Uranium, Copper, Iron Ore, Diamonds, Manganese Nodules, Gold Nuggets. Please note that the Diamond and Manganese Nodule fertilities aren't minable by a Metal Converter.
Manually stopping a Black Smoker
Usually, the Black Smoker will cease activity after a certain period of time after researchers are in residence on any island, but the player can stop it manually in two ways.
Method 1: Fine Chemicals
|Construction Cost||1500 · 15 · 10|
|Effect||Stops the activity of a Black Smoker.|
|Description||Complicated, but effective!|
|Development Time|| 45:00|
|Development Risk|| 15%|
The Fine Chemicals is a Laboratory Module that will instantly end the activity of a Black Smoker on an Underwater Island once activated. After ending the activity af a Black Smoker the Underwater Island will develop a random (Iron, Copper, Gold, Uranium) Raw Material deposit.
Method 2: Academy Technologies
It is also possible to manually stop the activity of a Black Smoker by developing these technologies in the Academy under "Fertilities and Resources" (all of which require 3 Fine Chemicals to develop):
Please note that these items are not longer available in the Deep Ocean expansion.
Black Smokers in the Deep Ocean Expansion
In the Deep Ocean expansion, black smokers no longer stop smoking, and there are no academy items to turn a Black Smoker into a particular resource. Instead, you construct Metal Converters of any type near a Black Smoker to mine metals.
