death star's reactor outputs the the power equal to a small STAR. If it just sits around doing nothing it can be maintained indefinitely So no i did not miss what would happen if the crew vanished. 1/3 the crew are droids on death star built on death star. Storm troopers and imp officers ARE MOSTLY clones. No they are not produced on death star; They are produced to manage and run the death star though. The death star has life support; barracks; mess halls; and food production and waste management ; IT WAS designed to support a manned crew and depend on it.
