For this post, I'm giving the details of all city improvements. Some can only be built by humans, others only by klackons. This depends on if the tech required to build them is race-specific.

Algae Farm
Algae is one of the simplest living things in existence, and one of the oldest on most worlds. Long before a planet develops animals, plants, or even multi-celled organisms, blue-green algae appear, invent photosynthesis, and flourish--adding oxygen to the atmosphere in the process and, in many ways, paving the way for more complex forms of life. As the biosphere progresses, algae become a source of food for uncounted larger species. The algae farm takes advantage of this primordial organism's usefulness. Grown in giant vats, crops of algae can be processed into food for citizens and used as feed for other edible organisms.

Biochaotic Generator
The development of the biochaotic generator is a success story with ironic tragedies built in. When biomathematicians solved the fundamental equations of chaos biogenic theory, the solutions pointed to a way of extracting vast amounts of energy from the mutational potential locked in every living cell. While this power is extremely useful for industrial and civil purposes, the obliteration of several labs--and the entire ecosystem for several square miles around every one--showed that the biochaotic energies involved were quite difficult to keep under control. The later discovery of attractors in Frazier biocomplexity geometries ("green attractors") allowed the creation of a feedback leash for this reaction, removing the threat of a wild hypermutational chain entering the local ecosystem.

Capital
When the survivors emerged from whatever broken pieces of starship they had ridden to the ground, the first priority was assuring their own long term survival. Later, it fell to the more foresighted among them to organize their ragtag communities into cities. Government quickly became structured and formalized, and the leader of the first city established headquarters from which the business of running the new empire was conducted. In many cases, these buildings also served as the living quarters of the leader. As cities grew prosperous, these facilities expanded into large campuses. The richly adorned, imposing buildings are a source of civic pride, and they help to reinforce the aura of power surrounding the leader.

Carbonarium
Long ago, intelligent civilizations realized that power generation via chemical combustion--burning carbon-based materials such as fossil fuels--is not only brutally inefficient, but also so dangerous to the global environment as to be considered barbaric and unethical by any advanced species. Nevertheless, it is also recognized as one of the necessary early steps toward building an industrialized society that is capable of supporting the scientific effort needed to advance to civilized methods of power generation. The Carbonarium is the most efficient combustion facility we are currently able to build; it does generate an unfortunate amount of particulate pollution, but much of a city's garbage and unwanted organisms can be fed into its indiscriminate ovens, thereby offsetting, to some extent, the filth it produces.

City Shields
From the earliest days of civilization, cities have constructed walls to protect themselves against raiders, bandits, and enemy attacks. These walls often represented a major investment in both time and materials, and required years to complete and constant repairs to maintain their strength and integrity. With the discovery of E-M repulsion field technology, we can protect a city in the same way by erecting two concentric force fields surrounding the city. When active, these shields repel the very atoms of any unit attempting to approach, slowing the attackers (if not halting them completely), and giving the defenders a significant advantage. Why two concentric rings? This strategy is borrowed from ancient times. A unit that somehow breaches the first shield is then trapped in an area with no hiding places and no cover--a killing field--between the two repulsion fields.

Collapsatron Q
The development of the Vastly Parallel Quantronic Wave Function Collapse Computing Device (VaPQWaFCoCoDe), commonly known as the Collapsatron Q, began decades before our original mother ship was launched from the home world. "Quantum computing" was the old term for the primitive--and entirely theoretical--wave function collapse calculation schemes. It was not until the fortuitous development of quantronic theory (and the resulting control over Bose-Einstein condensates the size of small buildings) that the possibility of computing via the collapse of an artificially sustained, multi-tiered quantum wave function became technically feasible--an exercise for engineers, rather than mathematical theorists.

Deep Dome
Every land based species on record has longed to expand into the seas. While there is no shortage of living space on Funestis or in this system, there are abundant natural resources under the oceans that await exploitation. Taking advantage of these resources is only a matter of technological advancement. The deep dome is one giant step in the right direction. This completely automated, fully robotic undersea mining and processing plant is designed to withstand pressures and environments that would destroy any known biological organism. Once set in place, the deep dome (named for the rarely used, domed and pressurized maintenance area) starts churning out industrially useful materiel at a dependable rate, ignoring weather, political upheavals, and dangerous organisms equally.

Dopplegarage
History teaches us many lessons. One of the most often ignored is that in a population under a form of government that allows personal freedom, many citizens become unhappy when their loved ones are stationed in military units based far from home, especially in wartime. There have always been many ways to alleviate this unrest--many of them morally questionable--and modern medical technology has provided us with one more. In the local dopplegarage, any citizen can have a biologically perfect duplicate of the person they miss--a clone, in essence--grown in only a few weeks time. Though the duplicate has no mind to speak of, it seems to provide enough sense of the person's presence to prevent publicly significant unhappiness. There are ethical problems with this arrangement, of course, but in times of war, what enterprise is not suspect?

Emergence Center
The discovery of emergent systems has made it possible for us to build computing devices and robots that not only learn and adapt, but are also capable of inventing new characteristics and abilities for themselves (and their "offspring") when needed. Their existence is a tremendous potential boon to any city, but without an Emergence Center, much of that potential is wasted. This advanced agency (originally conceived and designed by a robot!) has many functions. It's a massive data storage facility, a central location (a home, if you will) for all of the emergent computers in a city, and a place where mobile ECs (robots) can go for both maintenance downloads and the fast-paced stimulation that only interaction with other ECs can provide, which has proved to be necessary to their "sanity". All told, this results in a tremendous increase in the amount of data income produced by a city.

FTL Drive Element
The drive system is at the heart of any space-going vessel; without it, the ship is just another object following the dictates of inertia. Of course, a faster-than-light drive is not a typical engine. A material object (a ship) cannot simply accelerate until it surpasses the speed of light--c. Relativity theory makes it clear that that would require infinite thrust. Rather, an FTL drive must circumvent the cosmic speed limit to reach superluminal velocities. The abaryonic hyperfusion drive does just that. In each Abaryonic Chamber, a micro-miniature particle accelerator catalyzes high-energy reactions between normal, baryon-based matter and some of the recently created non-baryonic elements. The reaction products and energies derived from this reality-warping event cause a field cascade episode in the Hyperfusion Coil. When the isolator currents are disengaged, the field cascade engulfs the entire ship, forcing the space around it through a phase transition and, effectively, propelling it beyond c.

Fulmine Ring
The Fulmine Ring disrupts enemy air attacks, giving defending units an advantage. This installation is best described in an excerpt from Bemoth Tog's article, "New Tools for the Defenders":
"I had never seen the alien-inspired plasma chamber before, and now I faced endless, dedicated banks of them. Conversation was impossible in that vast cavern, every sound drowned out by the hum of power straining to be freed. We took positions in the shielded viewing port near the top of the tower for the test. Even behind the shields, my hair stood on tiptoe. I don't mind admitting that the sound and the fury when they unleashed the lightning had me wishing I was cowering under a bed somewhere. Words like 'awe-inspiring' and 'magnificent' don't even begin to measure up to that experience. This was the angry hand of some ancient god brushing my shoulder. When the lightning formed into the circle around the city--what the engineers call the fulmine ring--I breathed a hearty sigh of relief, glad that this elemental force was on our side. Then I went home to change my underwear."

Garrison
Confronted with a completely unknown, undoubtedly dangerous, and possibly hostile new world, we do not have the luxury of pacifism. Although war is not desirable, it is important that even the most peaceful society be prepared for the possibility. This installation provides a permanent facility where military units can be quartered, repaired, refueled, and generally kept in readiness. History teaches that when warring factions are closely matched in technology and manpower, battles are won by the better trained force. Therefore, these facilities also offer the benefits of a military academy, established for the purpose of training our defense personnel in the latest methods, tactics, and technology.

Gene Census
This ongoing project is a truly city-wide effort. All possible productivity, both materiel and work-hours, is dedicated to gathering data. Genetic samples are taken from the citizens, any animals and plants that can be found, the local environment, and any other source a citizen can imagine. Record-keeping, classification, and hunting down ever more facts become the primary industry for everyone not assigned to vital duties (such as food production and medical care). The census has been called "the triumph of taxonomy" by some, and it's as accurate a description as any.

GEnIE Park
Where are you planning to spend your next vacation? If you haven't already decided, you should give serious consideration to the local GEnIE Park. A Genetically Engineered Integrated Environment is the perfect place to relax, unwind, and recharge your creative batteries. Every one of these facilities is a beautiful natural preserve, with sparkling waterfalls, luxurious gardens, exotic plants and animals--and it's all totally safe! Inside the bubble, modern engineering and genetic techniques have created a little taste of paradise. What are you waiting for?

Gravitic Generator
Complete control over gravity has been a goal and a dream since that long ago day when we first discovered this fundamental force of the universe. Now that that dream is a reality, we find that applied gravitics have even more potential than anyone could have foreseen. This wondrous facility generates power for industrial purposes by drawing it from the gravitational well-field energy of any nearby planet. In simple (but unavoidably misleading) terms, the gravitic generator derives energy by damping minute shifts in the planet's gravitational field. (These shifts are one result of the ubiquitous phase-shift-like tensor eddies in an eleven dimensional extrapolation of the local Minkowskian geometry.) As the source of this energy is a part of the basic structure of local space-time, there is no potential for biotoxic pollution from the process. Apart from an immeasurably small hastening of the eventual heat-death of the galaxy, this energy source has no negative consequences at all. The gravitic generator also has one odd side effect that we do not yet fully comprehend. The biochaos in terrain in proximity to the generator is quiescent; the hypermutational curse is only half as virulent as normal.

Guild Library
Data collection and storage is a serious affair. As a civilization grows and becomes more complex, it develops a need for organizational structures to moderate the flow of information. Just as the guilds of ancient history acted to control and guarantee the quality and price of certain kinds of work, so the modern guild libraries act as centers of operation and data storage, ensuring the free flow and high quality of the information in a city. The usual result is an overall increase in the amount of accurate data available.

Harbor Town
Ever since the dawn of mercantile shipping, a certain type of neighborhood has grown up around any port. These areas are universally a source of experienced crews, both for manning vessels and speeding repair of damaged ships. Harbor towns also tend to be regions of less than savory reputation. Rather than waiting for the neighborhood to spring up on its own, modern city planners design and build an area intended for just this purpose. Subtle maintenance and quiet policing preserve the residents' free-booting way of life and their illusion of liberty while ensuring the safety of both the permanent population and the inevitable tourists.

Harvester
With advances in chaos biogenics, it became possible to "activate" a region of land to create ultraproductive farmlands dubbed "tohubohu" by agricultural specialists. In these areas, the crops grow and ripen so quickly that it is impossible to take full advantage of this fecundity without specialized machinery. That's where the Harvester comes in. This gargantuan, self-controlling robot with adaptive automata systems built in can harvest any crop with mind-boggling efficiency and speed. It analyzes the needs of a field, then performs whatever tasks are necessary--threshing, reaping, collection, or any other job. Once the produce is in the Harvester's processing bins, it is "deactivated" using primitive prionic stabilization techniques. This halts the biogenic ripening process and makes the food suitable and safe for consumption.

Hologaming Arcade
It's been common knowledge since the late twentieth century that computerized games and sports are one of the most addictive forms of entertainment ever devised by humans. With the invention of holographic total immersion techniques, the industry has been elevated to a new level--community service provider. In the ancient tradition of "bread and circuses" to keep the peace, a publicly funded full-service hologaming arcade can pacify an otherwise terminally malcontent segment of the population.

Hydroponic Reserve
Early in the history of colonies on the new world, small scale hydroponic farming of food plants salvaged from the wreckage of the starship were all that stood between the fragile colonies and extinction. The crops were grown in shallow water rather than the local soil, which prevented infection by local microorganisms and tainting by toxic substances in the dirt. The water was supplied with pure, chemically derived nutrients. When the settlers eventually regained some of the science that had enabled them to reach this planet, gene tailoring efforts transformed many of the local flora into safe and nutritious foods. A hydroponic reserve facility provides a dependable food source inside the city that is immune to both the vagaries of climate and to besieging armies. Its output is enough to provide a boost to the growth of the city, but not enough to sustain the entire city. Do not expect this to act as a hedge against starvation.

Infomatrix
Unforeseen advances in crystal thermionics led to breakthrough discoveries in systems for data storage, manipulation, and retrieval. The long and short of it is that finally, civilization realized the modern dream of handling information via non-volatile physical structures that allow super-fast state changes. The resulting design for the first Infomatrix, a centralized data management system serving all the research institutions in an entire city, had scientists getting in fist-fights over who would have first access. Eventually, everyone was able to use the device, and the free, extremely fast, unhindered flow of information proved the worth of the Infomatrix by greatly increasing the scientific output of every city in which one was built.

Instaporter
Before the invention of positronic computing devices, data transfer and processing capabilities were far too limited to allow effective instantaneous transport. The theory behind this technology is not new; the science is based on early explorations in quantum theory, of a side effect that was called "quantum teleportation" by the researchers of the time. Practical application of these primitive techniques proved impossible, however, and only the discovery of super-capacity computing brought about useful invention in this field. There are still uncertainties in the process, however. Transport over interplanetary distances--or even from a planet into orbit--is impossible, and specially designed interference (jamming) devices can interrupt and degrade the signal enough to prevent transport.

Investment House
Tracking the flow of data in a city is no small feat, and a great measure of inefficiency creeps into the system when there is no central monitoring station. The civil servants working in this facility, with the help of dedicated electronic brains, both watch the city-wide data-stream and exercise moderate control over it. Their subtle manipulations not only result in a smoother, more efficient, and ultimately more profitable tide of information coursing through the city, but also add substantially to the data income of the city government itself, through minimal channel taxes.

Justice Network
The Citizens' Compact is an explicit social contract. Under the Compact, one of the enumerated responsibilities of every citizen is to advance the honest, just, and fair application of the law. Cities under the rule of this extended honor system have no police forces as such, but early experience quickly taught that there were individuals who could not resist the temptation to abuse such a system. In response, the rewritten Compact called for the establishment of the Justice Network--a para-governmental citizen's group dedicated to the enforcement, on the rare occasions it becomes necessary, of the Compact's punishment clauses.

Laboratory
So long as society does not devolve into irrationality, science progresses regardless of whether there are facilities dedicated to it. However, its pace is slow. Without the proper instruments, research libraries, and other necessities that only a government-funded laboratory can provide, certain types of research are nearly impossible. A shielded place to perform high energy experiments, a clean room for genetic testing, a reliable power source for refrigerated storage of specimens--all these things add significantly to the research output of a city's citizens, and therefore of the empire of which the city is a part.

M.A.I.D.S.
The Metropolitan Automated Integrated Department of Sanitation (M.A.I.D.S.) was originally conceived and developed by Bilger Cybernetics Labs. It's a fully robotic, completely self-maintaining system of automated cleaning devices and sanitation robots. Cleverly camouflaged substations built into every part of the city open when necessary and disgorge whatever specialized equipment is needed for the task--debris removal, sewage flow control, or simple everyday dusting and garbage relocation. A M.A.I.D.S. system not only makes any city a nicer place to live, it also results in a substantial decrease in the incidences of disease, allergic reactions, and accidental poisoning.

Morphic Generator
Energy is one of the primary requirements for building a city's industrial capacity. While there are many ways to produce this power, history teaches that all come with a certain measure of pollution. The morphic generator is no exception, but it's better than a carbon combustion plant. Advances in the study of the hyperadaptive capabilities of heteromorphic ribonucleic acids make it possible to extract useful amounts of energy from the process of mutation itself. It's a complex and expensive process--and the cancer rate among workers in the generator facility is extraordinary--but the end result seems well worth it. Industry gets the power it need, and as a beneficial side effect, a city can divert fully half of the biotoxic industrial waste materials it produces into the morphic tanks, thereby significantly lowering the potential for causing biological instability in nearby regions. In addition, any power generating facilities based on combustion can be decommissioned.

Mutandis Museum
It is one of the embarrassing realities of our culture that the "freak show" has always existed in one form or another. From the ancient carnival sideshow through so-called "docudrama" television and the Anomaly Net, our species' sometimes cruel fascination with the unusual individuals among us has never flagged for long. The Mutandis Museum began its history as just such a show, flaunting the odd mutations that exposure to this new world caused. Eventually, however, with the development of genetic science and its concomitant art forms, the museum became something more. In its modern form, the Mutandis Museum fills many roles. There is still the prospect of the bizarre to draw those citizens who desire to view it, but these facilities have gradually evolved into institutions supplying both science education and the display of artistic endeavor. The result is strangely fascinating, and it serves the community, as well.

Nucleon Shield
One spin-off of nucleonic technology is that it allows precise localized control of the molecular organization of the air itself. Installed in a broadcast tower situated at the apex point of a parabola that covers the entire city, a nucleon shield generator can create a field that instantaneously restructures the molecules in the atmosphere around both the city and surrounding countryside for a few nanoseconds--solidifying the air into an indisintegrable quasicrystal for long enough to nullify the destructive effects of any disintegrator weapon.

Orrery
In these times, when our civilization is painstakingly digging its way out of the primitive situation into which we have fallen, it is often comforting to reflect on the accomplishments of our forefathers--accomplishments we hope to match and outdo someday soon. It was for this reason that citizen Crawley built the first prototype orrery--a large clockwork device illustrating the regular movements of the planets in this system. Erected in the center of his village, it became a symbol of the spacefaring civilization we once were and will be again. When it became clear how much joy this simple piece of scientific art gave the citizens of the town, Crawley designed a larger version suitable for a city.

Priodulcificator
No matter how careful and ecologically aware the citizens are, the population of any large urban center produces a vast quantity of waste materials. This is especially true of protean beings (Proteus Sapiens), who generate their own special forms of biological garbage. When a city is too big, the resulting outflow increases the chance that nearby terrain will collect a critical mass of bioactive materials and fall prey to a biochaotic chain reaction. The Priodulcificator is, in essence, a modern form of the ancient "sewage treatment plant" in which the biogenic structural energies of waste are prionically stabilized. This renders the materials inactive, leaving them completely harmless and useable as fertilizer or in other ways.

Satellite Uplink
As anyone who has lived in a technologically advanced civilization knows, it is not necessary to establish cities in orbit to gain some of the benefits of access to space. Fleets of artificial satellites in stable orbits--polar, equatorial, geosynchronous, and others--can relay massive amounts of data between any two points on the surface, vastly speeding communications of every type. When the government and citizens of a city can keep close communication with their capital city, it is almost as if the capital were not far away. Quick sharing of information helps reduce waste, inefficiency, and inaccuracy of many kinds. In addition, regular attention from high placed leaders can bolster the loyalty and contentedness of the city's residents.

Ship's Facility
Structure and propulsion are necessary, of course, but without a payload, there is no point to a vessel. The passengers carried on the first faster-than-light (FTL) ship are our emissaries to Earth--the nearest of the two original home worlds. Ship's facilities come in trios; one of each of the three types is required for the other two to function. Habitat is simply the living quarters for the emissaries. A Lability Cell ceaselessly provides the energies and materials required for the emissaries to maintain both life and protean flexibility. The Quantron Shield protects our representatives from dangerous side effects of both the abaryonic hyperfusion field cascade and the resulting FTL phase transitions.

Spaceport
To settle safely within the confines of a city, off-load cargo and passengers, and fill the holds with goods and persons for the next leg, a ship needs a port of some kind. In the special case of travel between planets, that port is commonly referred to as a spaceport. The facilities here are not significantly different in function from those in a seaport, though the techniques and the materials used certainly are. The biggest difference is that every spaceport includes a single-purpose vessel for interplanetary travel. These relatively tiny craft are not ships in their own right; they're a modified form of the emergency escape pods in which most of our ancestors rode to the surface of Funestis. Each pod can carry a single unit in deep-freeze suspension, and riding an ultra-fast trajectory, it can reach any friendly city in record time--but only if that city has a spaceport at which the craft can safely land. (Otherwise, the end result is too well scattered to even make a mess.)

Sphacelatorium
No matter how sophisticated industrial processes become, it seems that they will forever be burdened by dangerous by-products. Even now, when the majority of chemicals necessary for materiel production are generated by specially designed microorganisms, the specter of biochaotic pollution looms over every busy workshop. The sphacelatorium is an example of the same technology solving the problem that it has created. Advanced gene insertion techniques have allowed the creation of a novel bacillus that can break down virtually any organism or organic output a workshop or power plant might produce. Any biological "problems" are sent to this facility to be destroyed by a microorganism designed specifically for the job.

Superstructure
The mechanical stresses produced when the abaryonic hyperfusion drive is engaged are nearly beyond belief; no normal material could possibly withstand the physical strain of superluminal propulsion. Thus, there was no way to build structural components for such a ship until after the discovery of the ultra-tough monopolium compounds had led to giant leaps forward in the materials sciences. Each superstructural piece (especially the first, the spinal element) is designed to merge seamlessly with the rest of the ship, creating a hull-and-skeleton construction that is, in effect, a one-piece ship. Every additional bit adds to the strength and stability of the vessel. Without the requisite superstructure, none of the other parts of the ship--drive or facilities--will function.

Transmogrifier
Despite the claims made by some practitioners, transmutation is still really more of an art than a science. Changing non-living matter from one form to another is tricky. Even the finest facility needs an expert hand on the controls, and the best TransEngs (transmutation engineers) have an instinctive feel for the process that simply cannot be taught. With a good artist at the helm, a Transmogrifier facility readily converts common raw materials into rarer, more useful materials. This adds substantially to the productivity of the city's Workshop.

Tsunamines
Interdepartmental work to cross lines of specialization and combine developments in robotics and mechanized warfare made possible this advanced naval defense system. When a fleet of tsunamines is installed, the entire navigable coastal area near a city is seeded with semi-intelligent devices. When the advanced IFF sensors detect an enemy naval unit, the tsunamines send out a warning signal tuned to a classified, preset frequency. When sufficient time has elapsed that most civilian shipping should be clear of the danger zone, the mines self-actuate. Following an ultra-fast, chaotic stirring pattern, the mines whip the navigable lanes into a violent foment--much as the average hurricane would. Needless to say, this artificial tempest gives the forces defending the city a great advantage.

Workshop
Nothing can replace the independent craftsman, working alone, for sheer inventiveness and quality of workmanship. However, when what a city needs is quantity and speedy construction, a centralized workshop becomes indispensable. When the supply of tools, materials, work space, and machinery is collected in one central location, stored in a place known and accessible to all, and available at any time, the productivity in a city soars. Any citizen can volunteer his or her skills and free time to help out on whatever project is most important to the city--and given the chance, most citizens will. With the addition of advanced power sources, a workshop can continue to provide a boost in productivity indefinitely.
