for some reason i cant explain i am horrible with words... so if this is the worst composition of the English language devised by man, please forgive me. ps, be glad i have a spell check >_> late one night i was out on the balcony and something occurred to me. particle accelerators could be used to make small things. now hear me out. your old CRT TV that is sitting in your garage is a prime example. instead of accelerating atoms, slow them down to hit a target with precision. in effect it is possible to "stack" atoms like legos to make whatever. now back in high school i only heard of a machine that could layer atoms, but this is one at a time... sort of. now i have some problems: how do you confirm an atom has landed where you want it? you could make a sudo-error check, but it would have to be able to scan/see very small. i looked into it and the only thing i can find that is capable of "seeing" that small is a TEM, and from what i read it can only observe columns of atoms. one at a time? well isolating atoms one at a time is a pain, but pinching them down to a single file line isn't as hard. Penning traps use magnetic fields to encase charged particles, so its plausible to assume that you could squeeze a mass of ions into a 1 dimensional stream. no? referring back to the TV again: its plausible that you can assemble a decelerator/TEM hybrid that can work at high speeds, your TV does it all the time.... kinda. also, 3d printers go one layer at a time, similar to flashing pictures on the screen. aaaand im done... thoughts?
