A Collector is a technological device and a power source.
- It is a kind of Ship Equipment.
Collectors are energy-gathering and storage devices designed to accumulate energy. The term has been historically used to describe two similar, but different devices:
- Stellar Collectors gather energy from the electromagnetic emissions of a star and store them in a bank of charge accumulators.
- Particle Collectors absorb exotic particles from free space and store them in a collector-canopy for exclusive use by use by Jump Drive mechanisms.
One known example of the Stellar Collector type mentioned above has the following characteristics:
- "[The canopy of the Stellar Collector] is ... a skeleton framework and a circular thin black radiation-absorbent film about one kilometer in diameter." 
- "[The] Stellar Collector absorbs and collects energy for internal power and jump drives." 
- "The collector-canopy collects radiated stellar power and stores it in the accumulators on the drive deck. 
- Accumulators can typically store enough energy to power the jump drive(s) once, as well as maintain internal life support under normal conditions.
- Duration of internal power [for this particular example]: 60 days under ordinary load. 
- Required recharge time: One to six weeks, depending on the distance from, and spectral type of the star serving as the radiation source." 
Collectors of various types become available much earlier than the TL-14 mark at which point they become commercially viable and competitive in terms of performance with other power sources available to starships and other technological devices.
