Infrastructure

One of your long-term objectives is to unlock new technologies from the branches of the tech tree. In the aftermath, much of mankind’s knowledge was either lost or outright destroyed. Fragments can still be recovered from various locations on the world map to aid the colony. The research locations can be searched for Science points which, unlike other resources, are immediately available for the colony. And the bigger your specialists' research skill is, the faster they can extract all the usable knowledge a particular location has to offer.

Branch focus

The Infrastructure tech branch increases the colony's production capabilities by focusing on:

• Energy producing buildings.
• Water producing buildings.
• Heat producing buildings.

Category legend

Each researched technology offer one of eight unlock effect types. These can be determined at a glance by the tech frame's top color and are as follows:

• Building unlock - Unlocks a new building.
• Building upgrade - Unlock a building's upgrade option.
• Durability - Improves buildings' protection against natural deterioration or elements like cold or Pollution.
• Efficiency - Improves the speed or amount of production.
• Ideology - Special improvements based on your chosen ideology (survival, production, safety).
• People - Affects or improves people's lives and Happiness.

List of technologies

	Technology			Type	Unlockables	Prerequisites	Description
	Water Pipes	10h	100		Water Tower	N/A	Allow transporting water to buildings via water towers. Building a working pipe system allows the colony to take steps toward a more modern society.
	Directed Heat	12h	125		Boosted Burner	Water Pipes	Directing the heat from burning firewood more efficiently via a series of plates means buildings farther away will catch some of that heat.
	Large Drums	12h	125		Large Clean Water Storage	Water Pipes	When it comes to drinking water, you can never be too prepared. Storing clean water in massive tanks ensures your colonists can survive through any drought or heat wave.
	Solar Power	14h	150		Solar Panel Transformer	Either: Directed Heat Large Drums	Getting the power back on is a major step toward rebuilding a civilization. Solar panels are an efficient way to produce energy during the day.
	Panel Coating	12h	125		+40% Durability to: Solar Panel Large Solar Panel	Solar Power Production	Solar panels are not the world's sturdiest invention, and flying debris and extreme weather can slowly wither them. Coating the panels with translucent material increases their durability against all sorts ot threats that the apocalypse throws your way.
	Pavement	16h	250		Paved Road	Solar Power	Caesars and pharaohs figured stone-paved roads were the way to bring a bit of civilization to a settlement — and keep their sandals clean. Faster movement on paved roads.
	Energy Storage	16h	250		Battery Rack	Solar Power	Producing energy without storing it can be a recipe for disaster. Repurposed battery racks can hold a decent charge and keep things running even when energy production has halted.
	Drilled Wells	18h	350		Drilled Well	Energy Storage	Digging a well by hand is no easy task, so the shaft is often too shallow to reach all the underground reserves. Basic drills simplify the process and provide more water for the colony.
	Bigger Barrels	18h	350		Large Water Tower	Energy Storage	Constructing large, structurally sound and waterproof barrels for is surprisingly difficult. It takes a lot of trial, error and leaking water before perfecting large water towers.
	Wind Power	1d	400		Wind Turbine	Either: Bigger Barrels Drilled Wells	Getting the power back on is a major step toward rebuilding a civilization. Wind turbines provide a reliable and steady energy source.
	Tough Bearings	18h	275		+40% Durability to: Wind Turbine Large Wind Turbine	Wind Power	The ball bearings of wind turbines are in constant motion and prone to breaking or jamming, so strengthening the power plants' crucial parts increases their durability when things get rough.
	Deep Drilling	1d 4h	500		Bore Well	Wind Power	Clean water can be hard to come by, especially in dry climates. Bore wells are drilled as deep as required to tap into water reserves, which allows placing them on any soil type.
	Drillmaster	1d	350		−50% Energy consumption to: Bore Well	Deep Drilling	There's a lot a learned engineer can do to improve a seemingly simple design. Using every possible trick to save energy means worrying less about power plants while travelling outside the colony.
	Powered Heaters	1d 4h	500		Radiator	Wind Power	Burning wood to heat a growing colony is labor and resource intensive. Moving toward powered centralized heating with the energy-based radiator frees up colonists to do other, more important work elsewhere.
	Efficient Heating	1d 1h	350		−50% Energy consumption to: Radiator Industrial Radiator	Powered Heaters Survival	Adding thermostats to adjust radiator energy consumption makes them more cost-effective in the long run.
	Amplification	1d 12h	600		Large Transformer	Either: Deep Drilling Powered Heaters	Normal transformer signal can be amplified with a few simple modifications. The resulting radius allows energy to be transferred over great distances.
	Big Panels	2d	700		Large Solar Panel	Amplification	Large solar panels provide cheap, clean energy in moderate quantities. Solar panels shut down during the night.
	Advanced Heaters	2d 6h	800		Industrial Radiator	Big Panels	Upscaling heat production with the industrial heater results in transforming more energy into heat at a significantly wider radius than its smaller counterpart.
	Battery Stacking	2d	700		Large Battery Rack	Amplification	Producing energy without storing it is just a waste. Tinkering with battery racks allows them to be chained together for even greater effect. They will keep things running even when energy production has halted.
	Submerged Pumping	2d 6h	800		Water Pump	Battery Stacking	Gathering water with buckets is cute and all, but a big colony needs bigger solutions to procuring water in volume. A high-tech water pump on the shore provides just that.
	Axial Flow	2d	575		−30% Energy consumption to: Water Pump	Submerged Pumping	Some clever engineering allows water pumps to circulate the fluids through axial paths, reducing the amount of energy required to run them.
	Large Rotors	2d 18h	1000		Large Wind Turbine	Either: Advanced Heaters Submerged Pumping	Large wind turbines provide clean energy in large quantities.
