Most speculative potential applications
(Warning: this page contains highly speculative information.)
previous: further improvement at technology level III
Some things can only be done in meso- to macroscopic size scales. Those will also be improvable by APM but since complex products composed out of a multitude of advanced AP metamaterials are already speculative, technologies based on their interplay are most vague.
Applications which make heavy use of electronic optic magnetic and other non mechanical physical properties will require a lot of scientific investigation to make less vague predictions (see: Non mechanical technology path).
- diamondoid artificial ion channels (very likely possible)
- self cooling cryogenic cells for e.g. synthesization of small non-diamondoid molecules
- mining - advanced bulk preprocessing
- generation of radio waves by mechanical rotation of charges
- optomechanic applications
- neutral molecule carriage particle accelerators
- non biological multi limbed sensory equipped shells of all forms including humanoids
- artificial brains that can accommodate human consciousness scanned from brains of deceased persons
- use of APM for nuclear fusion
- successful terraforming - see air using micro ships
- solid state earth core probes
speculative topics about advanced spaceflight:
- novel launching facilites
- usage of gas giant atmospheres

Even further ahead there might (or might not) lie a zero sum situation Warning! you are moving into more speculative areas..
