Quick Jump: List of Technologies


Technologies[]

During the game all nations will race to discover more powerful advances (technologies.) A few advances provide immediate benefits, such as making new actions available to your units. Many introduce new units or buildings you can construct. Most are gateways to further technology. Beware that some advances also make things obsolete. While obsolete units merely become impossible to make, obsolete buildings are immediately sold, and obsolete wonders lose their effect.

By default, each player starts with no technology (this could be changed with the techlevel server option). You direct your research toward one advance at a time. Research progress is measured in research points which are called "bulbs." You can generate your own bulbs through trade and scientists, or receive them from others through blueprints. Unlike gold, which can be transferred or spent on anything, bulbs are research knowledge tied toward acquiring a specific technology. Each technology has a specific bulb cost. The more nations who already know a technology, the more the bulb cost will be reduced, due to a phenomenon called techleak. (See /help techleak).

Each "bulb" or research point you generate is permanently credited toward the technology that was researched when it was generated. The technology becomes "discovered" and usable when you acquire bulbs equivalent to 100% of its bulb cost. If you switch technology goals, you will start learning the new technology from zero again. You will keep a research bulb credit toward your previous research, which will be there when you come back to your previous research.

Instead of selecting each new advance manually, you can establish a long-term goal that is several technologies away, and your scientists will work through all the prerequisite advances automatically. (In Freeciv-web, you can do this by 1) clicking a far off tech for which you do not yet have the pre-requisites, 2) middle click, 3) alt-right click.) You can open the Tech tab at the top of the screen to view science progress and set new tech goals. The online hover-help system displays information for every item and technology in the game, allowing you to explore technologies and the capabilities they unlock.

Blueprints[]

The only way to learn a technology is to research it. But there are several ways to more easily gain advances from other civilizations. You might discover blueprints for enemy technology when you capture a city. You can steal blueprints with Diplomats and Spies. Another player may give you technology blueprints in the terms of a pact.

In older game versions, events such as city conquest and technology theft immediately awarded you a technology. This is no longer the case.

Tech theft through espionage, city conquest, and tech trade give you blueprints. Blueprints are a non-transferable bulb credit toward a specific technology advance. The bulb credit reduces the remaining bulb cost for researching the advance. A blueprint fills a technology's bulb account up to but not past the blueprint's value toward that technology. Bulbs are not like "wallet dollars" you can transfer from one research project to another. It is a waste of research effort to acquire partial bulbs into a tech for which you later get blueprints, since the bulb account for a blueprinted tech will not exceed the bulb value of the blueprint.

The Space Race[]

If the server option is enabled, the game may be won peacefully by building a spacecraft and becoming the first civilization to reach Alpha Centauri. To enter the "space race" you must complete the Apollo Program. This allows every you with the necessary technology to begin building spacecraft components:

B.space modules.png Space Module

cost:2000 upkeep:0

requires:Superconductors

B.space structural.png Space Structural

cost:500 upkeep:0

requires:Space Flight

B.space component.png Space Component

cost:1000 upkeep:0

requires:Plastics

The skeleton of your spacecraft consists of structural components, each of which can hold in place either a component or module. Components provide fuel and propulsion systems, and decrease the amount of time your craft will require to reach Alpha Centauri; you can install up to sixteen, though they must be installed in pairs. Modules themselves come in three flavors: a habitation module provides living space for ten thousand colonists; a life support module can keep ten thousand colonists alive; and a solar panel provides the power required by any two other modules.

Use the spaceship window to observe your progress as you build your spacecraft. You may manufacture spacecraft elements anywhere with a factory; they will automatically be assembled in your capital city. As you add components you improve the craft's probability of success and travel time; you may launch as soon as you find these satisfactory. If several civilizations are building spacecraft, they are faced with the decision of whether to launch quickly and start their craft on its way, or continue building in the hopes of launching a faster spacecraft later, or one with a higher probability of success.

During construction and after launch, the spaceship is considered a building of your capital city. It will be lost if your capital is taken or destroyed.
