Equipment classification: P - Power. Power Supplies. Power Cells. Energy Sources
The high technology personal equipment so many rely upon requires a continual source of power to operate. Most of the time the power required can be supplied by the local power grid or the starship Power Plant. Many devices include a small battery or power cell to allow for operation for several hours to several days. These power storage devices require recharging at periodic intervals.
Power for these devices can be supplied by chemical fuels, nuclear reactions like fission or fusion, or via anti-matter decay. The devices to convert these fuels into usable power can be very small, portable devices or large installations.
An Anti-matter Battery is a high technology energy storage device. As found, it is a small box finished in grey metal, with two gold colored contacts on its upper surface. The two contacts will provide almost unlimited current. The Battery operates by a controlled flow of anti-matter against an ordinary matter core. Flow is metered in response to demand, and very high levels of current are available. 
Anti-matter batteries are quite resistant to damage but are not armored or impervious. This type of battery is constructed to bleed energy slowly if broken or cracked. As a result, the battery will flash brightly for up to twenty minutes with very bright light and intense heat.
Batteries measure 6cm by 4cm by 10cm, and weigh about two kilograms.
Antimatter power plants come of age in the TL:16-18 technological epoch. Early prototype weapons become available in this time, but they have significant shortcomings. By TL:19-21, Antimatter becomes mainstream, affordable, and adequately miniaturized to widely used in smallarms, consumer vehicles, and even consumer goods. 
Batterized Portable Generator
|Batterized Portable Generator|
A Batterized Portable Generator is an array of batteries mounted in an open frame with a number of power connection options. The 540Mj battery array can supply up to 4 Kw of power for 37 hours. Or correspondingly less power for longer periods. The whole thing may be recharged with any standard power source.

A Body Generator is a set of equipment which is worn on the body and generates electricity, by the actions of walking or breathing. These generators are often incorporated into suits, such as stillsuits or very cold weather clothing, but they can be worn under ordinary clothes and used to power small electrical devices. The body generator consists of a few small electrical generators, attached in series to a small storage battery, and mounted in an undergarment.
One pair of spring generators are mounted in the footgear, where power is generated from the action of putting the foot down. Another pair of spring generators are mounted on an undershirt, under the arms, where power is generated by swinging the arms. Often, a third pair of generators are mounted on the hips or thighs, and power is generated by stepping. Additionally, a set of spring straps mounted in the undershirt around the chest uses the action of breathing to generate power.
Overall, a body generator can generate enough power to keep two small electrical devices charged. These can include pumps, heaters, lamps, or small electronic devices, such as communicators, inertial locators, motion trackers, or language translators.
Body generators usually include a small, hand-powered squeeze generator, wired to the sequence, and kept in a pocket, to be used in case of failure of one or more of the generators.
Fuel Cell Portable Generator
|Fuel Cell Portable Generator|
The Fuel Cell Portable Generator has a Fuel Cell mounted in an open frame designed for being carried by one or two people. The fuel cell runs on liquid hydrogen, and the fuel tank holds a three-hour supply. The generator outputs a maximum of 4 kW. The fuel cell requires atmospheric oxygen to operate correctly, though there is an adapter kit which adds a liquid oxygen supply and captures the resulting water exhaust.
Fusion+ Portable Generator
|Fusion+ Portable Generator|
A Fusion+ Portable Generator is a small Fusion+ generator mounted in an open frame, designed for being carried by one or two people. The generator outputs a maximum of 4 kW. The generator has an internal 1-year fuel supply.
Internal Combustion Portable Generator
|Internal Combustion Portable Generator|
An Internal Combustion Portable Generator is a portable electrical generator powered by an internal combustion engine with a maximum output of 3 kW. The generator uses a hydrocarbon fuel and comes with a tank which holds a three-hour supply. May only be used in a thin or better atmosphere, which has a sufficient oxygen supply. The engine and generator are mounted in an open frame with handles to allow two people to carry the entire system.
A Photovoltaic Cell is a device that converts light energy into electricity via the photovoltaic effect, where the photons trigger the release of electrons in a semi-conductor material. These devices are also known as Photoelectic or Solar cells, the latter based upon the usual source of light to power them.
In most cases PV cells are gathered into a large array to provide more power. Most PV cells are about 1cm square.
These cells are mounted on a light aluminum or flexible plastic backing with a transparent cover to protect the cells from incidental damage. This is sufficient for light weight consumer goods. For industrial use, the cells are mounted on a heavier backing and given a stronger (but more transparent) cover.
Usually discovered around TL–5, PV cells become commercially available at TL–6. Primitive PV cells are highly inefficient (1% or worse) usually because the semiconductor material is sensitive to a single or limited array of wavelengths. At TL–7 this efficiency has improved to 6%, 15% at TL–8, and, with the addition of multiple layer crystal systems, 40% at TL–9.
Photovoltaic cells are an especially well adapted power source for Space Stations which are orbiting near a star: the PV panels may face constantly the star and receive a constant light radiation, thus giving a constant power output. PV panels having very long lifetimes (up to 30 years at TL–9), they make an interesting power source for such isolated stations.
Power Cells are a sealed power storage system. It is an energy storage system to supply power for small devices. Most small devices include power cells internally to operate for a full day. Recharging the power cell requires an external power supply and takes about an hour.
Radiothermal Portable Generator
|Radiothermal Portable Generator|
A Radiothermal Portable Generator is a small, portable radiothermal generator mounted in an open frame for easy carrying. The generator outputs a continuous 2kW of power. The system requires no fuel and runs at full power for approximately 15 years. Thereafter the power produced falls off as the radioactive decay rate in the generator slows down. The generator produces a significant amount of heat, and the generator design incorporates several cooling technologies.
At TL–13 the generator incorporates a damper box to hold down the rate of radioactive decay and reduce the heat output while it's not being used. If unused the RTG can last for several decades with full output on demand.
Solar Fuel Station
|Solar Fuel Station|
The Solar Fuel Station is a portable solar powered liquid hydrogen generator. It uses a collection of photovoltaic cells mounted on flexible panels to power a small central unit. The system comes with two panels, each 3.5m by 3.5m which produce 200Kw in the habitable zone of most stars. The power is used to crack water into the component parts of hydrogen and oxygen. The hydrogen is then cooled to a liquid state and stored in a 20l tank. The oxygen can either be vented or captured into a separate tank.
Each liter of liquid Hydrogen requires 142 liters of water and produces 114 liters of liquid oxygen as a byproduct. This process takes about an hour per liter of liquid hydrogen produced.
