Star Trek: 10 Things We NOW Know About The Holodeck
7. Fancy A Pint?
In times of crisis, head to your local (holographic) boozer and grab a drink. It may not be real, but it's safe, it's comfortable, and it's got its own power source. Standard issue in the late-24th century, but it wasn't always so.
A Space Adventure Hour tips its hat to the holodeck as it functioned from Star Trek: Voyager onwards, as an independent system, free from the rest of the ship's power supply. Scotty's suggestion seems to have taken a while to implement, as it was still connected to the rest of the ship as late as Booby Trap.
In this third-season episode of The Next Generation, Geordi works with a holographic Dr Leah Brahms, only for their simulation to abruptly cut off when the Enterprise's power reserves began to drain. By Voyager's first and third seasons, the holodeck now had a power supply that wasn't impeded by the requirements of the rest of the ship.
Star Trek: Picard introduced the idea that the holodeck could serve as a sort of disaster deck, with an autonomous power supply, offering shelter to a crew in need. It was here that Picard and Jack Crusher began to thaw the ice in No Win Scenario, though Shaw's memories of Wolf 359 killed that happy moment shortly afterwards.
