Enertron
From Chrono Compendium
General Information
Chrono Trigger
An Enertron is a special device in 2300 A.D. that allows Humans to obtain a full night's rest in moments. It allows the survivors of the Day of Lavos to remain healthy, though the agony of hunger and an empty stomach is not cured by the machine. This fact led to a famous line and sound effect that read, "But you're still hungry..."
Chrono Cross
An Enertron appears near Nadia's Bell in the Dead Sea.
