Osmotic Generator is a technology.


Osmotic Generator is a propulsion upgrade for the Nautilon submarine. It lowers the fuel drain of all movement within the Exocraft, extending the distance it can cover before the Humboldt Drive requires recharge with a Hydrothermal Fuel Cell.

Game description[]

Installed into the drive system aboard the Nautilon Submarine.

Captures energy by exploiting the saline gradient in deep water environments, allowing a slow recharge of the Humboldt Drive in the event of fuel emergencies.


Osmotic Generator can be built using a blueprint and the following ingredients:

Osmotic Generator can be dismantled after construction, returning the following ingredients:

Additional information[]

  • Osmotic Generator triggers Upgrade bonuses when installed adjacent to the Humboldt Drive or any of its procedurally generated upgrades, further increasing fuel efficiency.
  • It does not actually allow recharge of the Nautilon, instead it simply reduces fuel burn.
