The passive cooler is a low-tech alternative to the cooler, a construction that absorbs heat from interior spaces at a rate of 19.8°F (11°C) per second. It does not require power or any advanced materials but will run out of fuel in 5 game days and must be restocked with 50 wood (the same as the build cost) to continue working.

Acquisition

Constructing a passive cooler requires Passive Cooler to be researched and a construction skill of 8. It requires Wood 50 Wood and is constructed in 200 ticks (3.33 secs).

Analysis

Passive coolers cannot lower the temperature below 17°C (63°F), so they cannot preserve food like electric coolers, but they can protect your colonists from extreme heat and prevent debuffs such as "Slept in the heat". They require research to be built, though tribal colonies start with the research already completed.

They are very fuel inefficient, even compared to running coolers on wood-fired generators, but have the great advantage of not needing electrical power to function. As such, they will save your beer in a solar flare.
