Gotcha there! *Thinks up 70 new Wheel options*
Edit:
- Aquatic Farms/Aquaculture (Shallows/Continental Shelf/Deep Ocean): Food can now be grown in the oceans.
- High-G Alloys: Alloys compressed to abnormal density. Likely good as radiation shields, heatsinks, armor, and projectiles.
- G-Composites: '3-D printing' of different kinds of High-G and normal materials in the same workpiece via fine-resolution G-fields.
- Carbon Nanotube Muscles: Allows for vastly more strength applications than any human or Space Marine could ever put out. Makes all Power Armor and Legio Cybernetica/Drone units much stronger, faster, and tougher than before.
- Advanced Recycling Systems: fusion-generated plasma incinerates garbage/unwanted materials down to the molecular level, combined with smart Industrial Nanotech to break the material down and filter into its constituent elements.
- Mining: Auto Miners. Kilometer-long monstrosities, these automated barges carry fleets of probes and mining drones. They eat asteroids and given time can strip-mine entire planets all by themselves. They refine what they collect with internal foundries and offload the processed material directly to FTL courier ships.
- Mega Fabricators: No longer is Humanity limited to flash-fabricating micromissiles and other small trinkets. Torpedoes build themselves in their racks, ships repair themselves, and hangers construct new drones as fast as the old are lost. As long as you have the materials anything smaller than a light cruiser may be fabricated, and while size and complexity increase fabrication time, this still reduces construction from months to mere days.
- Mental Resleeving/Mind Transferrence: Patients chosen because of injuries too severe for conventional cybernetic or bio-implant recovery can benefit from this. The complex operation involved transferring the patient's mind into a newly cloned, younger body. Resleeving is incredibly labor-intensive, requiring years of preparation before and more years of rehabilitation after the operation. It is also fatal to the original host body, so there will never be two copies of the same person. Still, we can now transfer someone to a new (younger) body, theoretically keeping someone alive indefinitely. There is some loss of memories and skills during the process (2-5%), though this can be slowly recovered. It is also expensive, requiring a medical team for 6+ months, and the attention of skilled neurologists.
- Mobile Nanite Swarms (Military): Nanite Swarms can of course be weaponized, for better or for worse. Riots or other civil disturbances are not a problem anymore, as rioters find their nervous systems paralyzed via Nanite Swarms entering their body. Any form of unshielded Powered Armor Infantry or Vehicles can be infiltrated and controlled, depending on the whims of the nanite's controller or their programming.
- Militarized Nanite Swarms (ie "Gray Goo"): Von Neumann replication systems, making more of themselves out of everything. Considered a major WMD among all known space-faring civilizations.
- Anti-Nanite Swarm Swarms: "Fight fire with fire", basically. Only a counter-Nanite Swarm can defeat an offensive Swarm assault, neutralizing enemy opposition at the smallest source. Often deployed defensively at critical installations to enhance security.
- Automated Robotic Bases: Needs only a few Human operators, most things are handled by MOS-equipped drones, vehicles, aircraft, etc. Allows one to start massive resource expansion in relatively non-industrialized areas and create pre-prepared bases, factories, or cities with limited troops/personnel.
- Antimatter-catalyzed fission, fission-fusion, or pure fusion device: It's logical to use antimatter as an explosive, but nobody wants to carry large amounts of it around. Bottle nanograms/ micrograms of antimatter, use it as the initiator/trigger for a pure fusion nuke, using the weight savings to shrink overall warhead size.
- Gravitic field containment and emission capture (Grav Stealth) Trying to hide a ship in space is actually pretty difficult. Space is very empty and very cold, and starships generate vast amounts of heat from every ship function (premier among them life support, engines and reactor systems) that needs to be dumped into space. As well, active sensors broadcast signals across the EM spectrum and their artificial gravity systems create spatial distortions that can be picked up by the right sort of sensors. The GCC generator creates a specially tuned bubble around the ship to scatter the energy over a wide area. It should mean that instead of a single large hotspot it creates a wide area that's slightly warmer than average. Can be used to diffuse a variety of enemy energy weapons in combat, as well.
- High G world colonization: This project would allow us to colonize worlds possessing 10G or more, if need be. Does not include Gas Giants of any sort.
- Volcaniforming: Uses a weaker version of Geoharmonic Planetary Demolition to shatter the crust, releasing hot magma and volcanic gases to transform a planet that's useless to us otherwise into a volcanic world for mining.
- Prometheus Array: A Dyson Ring, as small as possible, consisting mostly of Solar (and Solar Wind) Collectors and Matter/Antimatter Generators.
- Attack Craft: Autonomous Escorts. Advances in automation and control have allowed for the creation of fully automated frigates. With no crew to protect or lose, these vessels are extremely deadly.
