Technology

This document captures the setting's "default assumptions" about everyday tech.

By 2375, humanity has lived with mature fusion power for over a century. The practical implications are profound: energy is cheap, manufacturing is heavily automated, and material scarcity—while not eliminated—has been dramatically reduced. The UEF provides universal basic income to all citizens; true poverty is rare and actively targeted for elimination.

This abundance has reshaped human labor. Robotics and automation handle most physical work. Humans contribute primarily through cognitive labor: art, innovation, research, skilled trades, and the oversight of automated systems. Service industries thrive, and there is a notable market for human labor among the wealthy—employing people where machines would suffice is a visible marker of status.

For many, this prosperity brings comfort but not purpose. A significant portion of Earth's population lives comfortably on UBI while consuming entertainment and recreational substances, but feels adrift without meaningful work. This ennui is one driver of the colonization impulse: the frontier offers purpose that the comfortable inner system cannot.

The sections below describe specific technological domains in more detail.

Power and Energy

Fusion

Helium-3 fusion is the foundation of modern civilization. The technology matured in the 22nd century and has been refined for over two hundred years. Modern fusion plants are reliable, efficient, and scalable from spacecraft powerplants to planetary grids.

He-3 is harvested primarily from the gas giants—Jupiter and Saturn—where atmospheric mining operations extract it from the upper atmosphere. The UEF maintains tight control over He-3 extraction infrastructure, and this monopoly is one of three pillars of federal power (alongside military dominance and political legitimacy). The recent licensing of corporate extraction at Saturn represents a potential crack in this monopoly, viewed with concern by some and opportunity by others.

Solar

Solar power is mature technology, with panel efficiency long since reaching practical limits. The constraint is collection area, not conversion. Solar works well in the inner system: Earth orbitals and Lunar installations rely heavily on solar farms.

However, solar intensity drops with the square of distance from the Sun. At Jupiter, solar provides roughly 4% of Earth-equivalent power; at Saturn, roughly 1%. This gradient is why fusion dominates the outer system and why He-3 is strategically vital.

Energy Storage

High-density solid-state batteries are standard for everything from personal devices to spacecraft auxiliary power. Modern batteries are safe (no thermal runaway, no liquid electrolytes to leak in microgravity), energy-dense, and long-lasting. Charging infrastructure is ubiquitous in developed areas.

Power Distribution

Developed installations—Earth cities, Lunar warrens, major Belt stations—maintain robust power grids. Smaller installations and spacecraft rely on onboard generation. Wireless power transmission exists for short ranges but remains inefficient for bulk power transfer; cables and direct connections remain standard.

Manufacturing

Automation and Fabrication

Modern manufacturing is highly automated. Robotic systems handle raw material processing, component fabrication, and assembly. Human involvement is primarily supervisory: setting parameters, troubleshooting problems, and making decisions that require judgment or creativity.

Additive manufacturing ("printing") has matured into a general-purpose fabrication technology. Industrial fabricators can produce complex components in metals, ceramics, polymers, and composites. Consumer-grade fabricators are common in homes and public spaces, capable of producing everyday items from feedstock cartridges.

The distinction between "printing" and "manufacturing" has blurred. Most goods are produced through some combination of additive fabrication, automated machining, and robotic assembly. Fully custom one-off items and mass-produced commodities come from the same fundamental technology base, differing mainly in scale and optimization.

Feedstock and Raw Materials

Fabricators require feedstock: processed raw materials in standardized forms. Common feedstocks include metal powders, polymer pellets, ceramic slurries, and composite precursors. The supply chain that extracts, refines, and distributes feedstock is a major economic sector—particularly in the Belt, where asteroid mining provides the raw materials that feed the system's fabricators.

Recycling is economically significant. Most materials can be reclaimed and reprocessed into feedstock. In closed environments like spacecraft and stations, recycling approaches 100% efficiency for many material streams.

Intellectual Property

In an economy where physical manufacturing is largely automated, intellectual property has become one of the primary drivers of remaining market competition. Designs, patterns, and specifications are valuable assets.

Fabrication operates on a tiered access model:

  • Open source: Community-developed designs, freely available. Quality varies; some are excellent, others adequate. No support, no warranty.
  • Licensed: Commercial designs available for per-unit fees or subscription. Higher quality, manufacturer support, regular updates.
  • Restricted: Weapons, controlled medical devices, and other regulated items require authorization to fabricate. Fabricator firmware enforces restrictions in compliant jurisdictions.

Enforcement follows the usual gradient: strict on Earth, maintained on Luna, nominal in the Belt, often theoretical in the outer system. Designs protected as proprietary on Earth may circulate freely on a Saturn station. A robust "maker" subculture treats IP restrictions as obstacles to route around, blurring the line between principled open-source advocacy and simple piracy.

Large corporations can afford legal enforcement and robust DRM. Individual inventors face a choice: open-source their work for reputation and community support, or sell to a corporation that can actually defend the rights.

Socialized Designs

Some designs have been declared public goods by the UEF and made freely available to all. This typically occurs when a technology is deemed essential to basic welfare or when proprietary control would create unacceptable inequality—the same logic that led the UEF to seize life extension treatments in the 22nd century.

Socialized designs include basic medical devices, essential habitat components, emergency equipment, and certain agricultural systems. The originating companies receive compensation (often disputed as inadequate), and the designs enter the public domain with UEF-maintained reference implementations.

The criteria for socialization are politically contested. Corporate interests lobby to keep the threshold high; equity advocates (including cetacean representatives, who consistently support broad socialization) push to expand it. Every few decades, a breakthrough technology triggers a new fight over whether it crosses the line.

Critics argue that socialization discourages innovation—why invest in R&D if your breakthrough might be seized? Defenders counter that the compensation system is adequate and that some technologies are too important to remain proprietary. The debate is unlikely to resolve.

Economic Implications

Automated manufacturing has eliminated most traditional factory labor. Combined with fusion-powered abundance, this has enabled the UEF's universal basic income: no one needs to work to survive.

Human labor in manufacturing now focuses on roles machines handle poorly: creative design, novel problem-solving, quality judgment, and customer relationships. Skilled artisans who work with their hands—woodworkers, metalsmiths, tailors—occupy a prestige niche, producing luxury goods for clients who value human craft.

The economic divide is less about access to goods (most material needs are easily met) and more about access to opportunity: interesting work, creative projects, social status, and the resources to pursue ambitious goals. This is the scarcity that remains.

Economy and Currency

The UEF Credit

The UEF credit is the universal standard currency, maintained by the Federation's financial infrastructure. Local currencies exist throughout the system but must peg their value to the credit within regulated fluctuation bands. Exchange markets are robust and automated, operating continuously across the system.

Decentralized Finance

Light-speed delays make centralized transaction verification impractical for interplanetary commerce. The financial system relies on decentralized protocols— descendants of early cryptocurrency technology, refined over three centuries into mature, stable infrastructure.

Automated escrow is essential for outer system trade. When counterparties are light-hours apart and cannot verify fulfillment in real-time, smart contracts hold funds until predetermined conditions are met. Escrow protocols are sophisticated, handling complex multi-party transactions and dispute resolution.

Corporate Scrip

In the outer system, corporate installations often issue their own scrip—nominally pegged to the UEF credit but practically constrained. Scrip spends freely at company facilities but exchanges at unfavorable rates (if at all) elsewhere. Workers paid in scrip find their earnings effectively trapped, creating the economic dependency that critics call "company town economics."

The UEF regulates scrip issuance in theory; enforcement in the outer system is another matter.

The Reputation Economy

Parallel to currency-based exchange, a robust reputation economy operates throughout the solar system—strongest in the Belt and among spacer communities, but originating in Lunar culture.

The system formalizes mutual aid: contributions to community welfare, favors performed, skills shared, and problems solved are tracked and recorded. This creates a transferable social currency—someone who has contributed much can draw on the community's resources; someone in deficit is expected to contribute before asking for more.

The unit of this social currency was originally called the lune, reflecting its Lunar origins. When the system spread to the Belt, many Belters chafed at the name's strong association with Luna and began calling it the favor instead. Today, both terms are in common use—"lune" predominates in Lunar communities and among spacers with Lunar ties, while "favor" is standard in the Belt and outer system. The terms are interchangeable in practice, though using one or the other can subtly signal cultural affiliation.

In tight-knit communities where survival depends on cooperation, favors often matter more than cash. A Belter with deep favor can get a ship repaired, find crew for a run, or secure emergency supplies—transactions that might never involve UEF credits at all. Conversely, someone with poor reputation may find that no amount of money opens doors.

The technology enabling this is straightforward: distributed ledgers tracking contributions, endorsements, and social vouching, with privacy controls that let individuals decide what to share. The cultural infrastructure is more complex—norms about what counts as contribution, how to handle disputes, and when reputation should (or shouldn't) be invoked vary by community.

The vast majority of communities explicitly reject corporate participation in the favor economy. The system is built on personal trust and mutual obligation; allowing faceless institutions to accumulate social currency would undermine its foundation. Corporations deal in credits or scrip, not favors. The line between "small business run by people I know" and "corporation" is drawn differently by different communities, and edge cases—family businesses that grow too large, worker cooperatives with outside investment—generate ongoing debates.

On Earth, the reputation economy is a curiosity—an interesting alternative system used by spacer expatriates. In the Belt, it's often the primary economy, with credits reserved for dealing with outsiders.
