Krellide power cell
From Memory Alpha, the free Star Trek reference
A krellide power cell is a part of an old Vulcan transmitter. The transmitter that Trip Tucker used to reach the Enterprise NX-01 when he was captured by the Andorians used a krellide power cell. (ENT: "The Andorian Incident")
Krellide is Rick Sternbach's homage to the aliens in the 1950s science fiction film classic Forbidden Planet. (behind-the-scenes commentary, Enterprise Season 1 DVD, "The Andorian Incident")
