Conceived of by J. Storrs Hall, Utility Fog is an application of nanotechnology in which a nanobots or foglets cluster together to form a shapeshifting mass that could perform a variety of functions and is not always visible to the naked eye. Each foglet is mostly made of telescoping arms and a nanocomputer and would be 6 to 10 millionths of a meter in size. Some of the arms would grip the ends of other foglet arms for power and communications connections while the others cling to the original structure.
