Doctor Giger and his Cellular regeneration and entertainment chamber
The cellular regeneration and entertainment chamber was a medical treatment device based on the theories of Doctor Bathkin of Andros III and built by Doctor Elias Giger in the 2370s. According to its designer, the chamber was designed to keep cells energized by "teaching" them "new mitochondrial tricks". The chamber functioned by transmitting biogenic energy on a chromoelectric wavelength, to send "uplifting and entertaining" messages to cellular nuclei. Giger predicted that, by spending eight hours a day in the machine, one's life span could be extended indefinitely – effectively bestowing immortality on the user.
Necessary supplies required for its operation included an ion-transtator, anaerobic metabolites suspended in a hydrosaline solution and a neodymium power cell. The device emitted highly charged polaric particles when in operation.
Though Federation scientists were extremely doubtful about the practicality of Giger's theory, Weyoun 5 became interested in the chamber during a visit to Deep Space 9 in 2373. (DS9: "In the Cards")
