Obtaining
They are found commonly in "Alien" crates and in the inventory of almost every enemy aboard  Mothership Zeta. At the end of Mothership Zeta, talking to Sally every 24 hours will give you a random alien item and around 40 alien power modules, however, you will not be told they have been given to you. This means the alien power modules are unlimited.
