Yoav, > Yes, but I think the nanobots are supposed to devour the entire earth, so it's volume that counts. The volume is about 1x10^21 m^3. So 40% is 4 x 10^20 m^3. But they start from the outside and eat down. This causes the surface area to decrease and less nonobots are required. Or to put it another way, the don't have to replace the earth with nonbots :-) > > 3.4 x 10^38 nanobots comes to 8.5 x 10^17 nanobots per m^3, or about 1.17 microns^3 per nanobot. > > Sounds about right. This must have been one of the design goals :-) Bob _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
