(speculativity warning!)

Utility fog is a concept devised by J. Storrs hall. Consult wikipedia for a basic introduction.

Utility fog is not the easiest product to create (well the mechanics may be not too complicated but the programming and system design like data transmission and fluid dynamics emulation is going to be very difficult) As many others it's not a product to expect early on.

Utility fog must not be confused with the concept of universal assemblers. They may superficially look similar because they both can feature legged mobility. Its not designed to replicate or even do mechanosynthesis. When it does recompose microcomponents it's not utility fog but Microcomponent maintainance units (which lack the wits for fluid dynamics and have vewer (eight) shorter and sturdier linking appendages. A specialised nanofactory will normally work faster than them but can't do live maintainance.

Modes

Naive mode

The units fill the floor densely and rise up to form some ********* when requested or do **** *** when some malicious computer virus took control.

Fog mode

The units fills a whole space and immerses all present humans and animals. A bubble around the head of breathing life forms is proposed.
It seems not too unlikely that software bugs can kill people in several horrible ways.

Transmission from the fogs surface to an holographic display inside the bubbles seems very SciFi.

It's yet unclear how transparent a strictly periodic undistorted utility fog crystal will be. If it's sufficiently transparent then whenever fluid dynamic activity is performed interesting optical distortions will occur.

Surface smoothing

Security

Accidental intake

Inhalation or ingestion seems to be a serious risk.

• Todo: extimate how much resistance to aitflow with and without capping utiliti fog will pose.
• Todo: check maybe existing literature on the effects of diamond to human mucosal

For a bit more security one could implement

• a minimal surface curvature
• a flow in speed limit for deep and slim crevices

Accidental environmental release

As with all AP products splinter prevention is an important issue. The legs must not break under any normal circumstances (hammer attack, gun bullet) but turn/flex away. Only projectiles with the speed of space debris (LEO orbital speeds) will not be handlable even with the best design. Cleanup?

If chunks must break of (e.g. due to high force shearing) they should be as big as possible.

Since utility fog is designed to be able to come apart at any interface at any time. A hardware mechanism is reqired that prevents units from letting go at all or most of its (twelve) linking appendages at the same time or else software bugs will undoubtably lead to massive spill of lost units that irrecoverably left the machine phase.

Possible use cases

• furniture (special purpouse AP products have the advantage that you can be sure that they won't do any nasty stuff with you)
• terrain independent cloud like wheelchairs
• crash-cushions - outside for unlucky pedestrians inside as replacement for the current nose breaking airbags.
• mellable computer interface - to design your nice or nasty stuff
• classical robotic manipulations
• telepresence - but AP suits work just fine and are less overkill - in both cases full- semi- and virtual reality become mixed up thouroughly. Recognition signs (like recycling symbols on plastic products) might be a good idea - so that in most cases you know what you are dealing with.
