Technology

Technology is dealt with using a tech level. A tech level is a measure of your nation's advancement. You have a tech level in various different categories: Of each of those tech levels, there are two different sublevels: Cutting-Edge and Common. Common represents the level of technology that is mass produced. Cutting-Edge represents the highest level of technology your nation has access to.
 * Energy
 * Computers/Robotics
 * Communications
 * Medical
 * Environment
 * Land
 * Water
 * Air
 * Space

Tech levels are upgraded in increments of 0.1 and are costly to upgrade.

Upgrading Cutting Edge Tech Level
Cutting-edge tech levels cost different amounts depending on whether it is the highest in the world or just the highest that your nation has developed.

If the tech level is higher than anyone else's in the world's tech level in that category, the cost is 300 × (target level)² × (number of countries working together)0.5

''For example, Bulgaria and England both want to work together on reaching Tech Level 7.8 from tech level 7.7. If this is higher than anyone else in the world, it will cost them 300 × 7.8² × 20.5, which equates to a cost of 25812, or 12906 each.''

If the tech level is not the highest in the world, the costs are less severe, however only one nation can upgrade it for itself, and no joint projects are allowed. The cost is 15 × (target level)².

''For example, Bulgaria wants to upgrade its tech level from 7.5 to 7.6. If tech level 7.6 is not the highest tech level in the world, then it will cost Bulgaria 15 × 7.6², which equates to a cost of 866.''

Upgrading Common Tech Level
Common Tech Levels cost to research depends on the amount of money your nation produces, amongst other things. You may not upgrade your common tech level to be above your cutting edge tech level.

The cost of upgrading your tech level by 0.1 is (the amount of money your nation produces) × (target level)². This means that it can be more expensive than common tech levels if your nation produces a large amount of money.
