Ship's Power Sources / Auxiliary Power

There seems tobe a discrepancy in the length of duration of various power systems when disconnected from the Main Power Plant. See underlined/italicized text below.

Centralized Power. The ship’s primary power source supplies all power to the operating mechanisms of the ship. Individual mechanisms or areas have short-term emergency power backups (= ship TL in minutes).Normal operations are powered from the Power Plant. If the Power Plant is damaged, disabled, or destroyed, individual mechanisms switch to emergency power and can continue in operation for a short period of time.

Decentralized Power. The ship’s primary power source supports its interplanetary and interstellar drives. Individual mechanisms (sensors, most weapons, control consoles) are self-powered and independent of the central power source.

• Power Cells. Although individual mechanisms are routinely connected to the Power Plant, they are supported by Power Cells (compact high capacity power storage cells) as an independent power source. Individual components can operate for hours (= ship TL in hours) after disconnection from the central power supply.

• Fusion Plus. The individual ship mechanisms are self-powered by Fusion Plus (compact cold fusion modules) as their independent power source. Individual components can continue to operate indefinitely (= ship TL in months) without a central power supply.

Compare the above underlined/italicized text concerning both Power Cells and Centralized Power Back-ups to the descriptions below:

Centralized Or Dispersed
A ship power system may have a single source of energy, or the sources may be distributed throughout the ship.

Dispersed. The power system supports its interplanetary and interstellar drives. Individual mechanisms are self-powered(with FusionPlus or Power Cells) and independent of a central power source.

● Fusion Plus. Ships may use Fusion Plus (compact cold fusion modules) as the independent power source. Individual components can continue to operate indefinitely (months) without a central power supply.

● Power Cells. Ships may use Power Cells (compact high capacity power storage cells; batteries) as the independent power source. Individual components can operate for (1D) days after disconnection from the central power supply.

Centralized. A power system which supplies all power to the operating mechanisms of the ship. Individual mechanisms or areas have short-term emergency power backups (1D hours).

Now compare the underlined/italicized text in both of the above to the text below concerning both Power Cells and FusionPlus:

POWER CELLS
The ship has an array of units which store usable energy. Power cells are dependent on an energy source to provide the energy that they store and release. Power cells are batteries: they store energy; they do not produce it. An operating Power Plant can charge multiple Power Cells in about a day.

Routine Energy Use. A charged Power Cell can support the operation of its assigned device for two weeks.

Operations. Power Cells are suitable for routine use of non-energy-intensive devices. In practice, they support Consoles, Computers, and Sensors. They are not suitable for Drives, Weapons, or Defenses.

FUEL CELLS
The ship has an array of units which convert a source fuel into usable energy.

Fuel. Fuel cells consume hydrogen and oxygen to produce electric current. Hydrogen can be obtained from standard starship fuel, or skimmed from gas giants. Oxygen can be obtained from any world with Atmosphere 2-9. Refined or unrefined status is inconsequential for Fuel Cell fuel. A single fuel cell requires one ton of fuel to support 10 weeks of operations for a Compartment.

Routine Energy Use. A charged Fuel Cell can support the operation of its assigned device for ten weeks.

Operations. Fuel Cells, like Power Cells, are suitable for routine use of non-energy-intensive devices. In practice, they support Consoles, Computers, and Sensors. They are not suitable for Drives, Weapons, or Defenses.

FUSION PLUS UNITS
The power plant uses a cold fusion process to produce usable energy.

Fuel. Highly efficient Fusion Plus units electrolyze water to produce hydrogen and waste oxygen.

Routine Energy Use. A charged FusionPlus can support the operation of its assigned devices for about a year.

Fuel Consumption. A small (several liter) water tank is filled with potable water as necessary.
