COST ESTIMATES. "For you to be able to afford them they’d better cost less than $0.00000000001 apiece. (If you were very very rich, you might be able to afford $0.000000001 Foglets.)" https://lnkd.in/ebphx-d View in LinkedIn

NUMBER OF HOUSEHOLD FOGLETS NEEDED. "Fog needs the self-reproducing productivity of nanotechnology to be economical. After all, filling an average house with even coarse 1 mm Foglets requires over a trillion of them, and for the hi-fi Foglets it’s a quadrillion (10^15) of them." https://lnkd.in/ebphx-d View in LinkedIn

UNDETECTED GRANULARITY UPPER LIMIT. "The upper limit for completely undetectable granularity is probably about 50 to 100 microns, the range of diameter of human hair. If “super high fidelity” isn’t critical, 1 mm Foglets would likely be able to do all the physical tasks of interest." https://lnkd.in/ebphx-d View in LinkedIn

UNDETECTED GRANULARITY LOWER LIMIT. "The only constraint on size is the ability to form a smooth enough surface to fool human senses. The lower limit, based on designs from Nanosystems, is about a 1 or 2 micron body and 5 to 10 micron arms." https://lnkd.in/ebphx-d View in LinkedIn

NANO AND FOG. "The only major breakthrough necessary to enable us to build the Fog world is nanotechnology itself. Assemblers, the sine qua non of nanotechnology, will require two major feats of molecular engineering: building molecular-sized, individually controllable, physical actuators, arms, motors, gears, sprockets, pulleys, and the like; and then building molecular sized computers to control them." https://lnkd.in/ebphx-d View in LinkedIn

ANATOMY. "Each Foglet has twelve arms, arranged as the faces of a dodecahedron. The central body of the foglet is roughly spherical, 10 microns in diameter. The arms are 5 microns in diameter and 50 microns long. A convex hull of the foglet approximates a 100-micron sphere. Each Foglet will weigh about 20 micrograms and contain about 5 quadrillion atoms. Its mechanical motions will have a precision of about a micron." https://lnkd.in/ebphx-d View in LinkedIn

PROGRAMMABLE SNOW. "They'll be able to make objects appear and disappear on command, and even make them hover and fly around. And through such forces as squeezing, hitting, and pulling, they'll also be able to manipulate objects in the environment." https://lnkd.in/eik9_rZ View in LinkedIn

UTILITY FIG. "It would essentially approximate multi-branched snowflakes that are barely touching each other — and interacting with it would feel like standing or moving through packed snow." This programmable "snow" ... could move around a person — and even move them around." https://lnkd.in/eik9_rZ View in LinkedIn

POWER HOUSES. "Each foglet would have a tiny computer inside to control its actions. "When two foglets link up they'll form a circuit between each them so that there will be a physical electrical network ... that way they can distribute power and communications." https://lnkd.in/eik9_rZ View in LinkedIn

"EACH FOGLET would have to serve as a kind of pixel. They'd measure about 10 microns in diameter (about the size of a human cell), be powered by electricity, and have twelve arms that extrude outwards in the formation of a dodecahedron. The arms themselves would be 50 microns long and retractable." https://lnkd.in/eik9_rZ View in LinkedIn
