¶ Activate
Activation is a free action that allows you to use an ability described on your technology, government, religion, or nation card. During your turn you may activate any number of your cards before, between, or after your main actions during your turn.
Certain cards can be activated during the achievement phase or cleanup phase. Please refer to its description for details. Some of them can be activated even during the turn of other players, as long as the specified conditions are met.
Once you activate a 
recurrent technology, put 
activation cube on this card.
