"Power Hungry" is the fifth episode of the first season of the American science fiction drama television series Fringe. The episode was written by playwright Julia Cho and consulting producer Jason Cahill, and was directed by Christopher Misiano. The episode focuses on Fringe Division's efforts in finding a man with the uncontrolled ability to affect electrical energy, thanks to the work of a wanted rogue scientist. Meanwhile, Olivia Dunham sees visions of her deceased lover, John Scott. The episode's premise began with the idea of a computer virus being able to spread to humans, which then evolved into the story of a man who comes into his unique abilities. Series consultant Glen Whitman noted the premise was based on the "very very weak magnetic field" of electrical energy surrounding humans that an EEG detects, and the writers simply amplified this. The special effects crew undertook much preparation to simulate a chase sequence involving an exploding transformer, leading guest actor Ebon Moss-Bachrach to note how scary the effect was to film. It first aired in the United States on October 14, 2008 on the Fox network, and was seen by an estimated 9.157 million American viewers, the network's second highest rated show for the week. Critical reactions of the episode ranged from mixed to positive, as many believed the series was finally finding its footing. Others however critiqued the episode for seeming too ordinary for a science fiction series.
