Active Technology Property (manual)

Any given technology can either be active or inactive. An inactive technology has no effect on the game and has a price in knowledge to develop.

Developing a technology will move it into the active state. Active technologies affect the game in some way. Further expenditures of knowledge can be made in order to refine them. Generally speaking, refinement improves the impact of a technology but does not make qualitative change to the impact.

For instance, if a technology enables an investment, then that investment will be enabled merely by developing that technology and refinement will only improve the effectiveness of the enabled investment.
