What Is Nano Technology ? How does Iron Man's nanotech suit Work?

[br] [br][br][strong]Nano tech - what it is now:[/strong][br] [br]So right now we have fairly small robots, but they don’t even qualify as a fun toy. Not much moves. In fact some people in the industry got excited about the creation of these ‘nanobots’ that didn’t do anything on their own but relied on eternal magnets to move them around. If that sounds more like an illusionists trick, well, it is. So we just have small, and not very tiny, and certainly not nanobots. Just little tiny semi-mobile devices that are not really autonomous, can’t really build anything, run out of power in minutes, barely get around if the surface isn’t flat, move incredibly slow and would be destroyed or rendered completely useless if you let a dog walk around in the same room - or a toddler.[br][br][strong]Nanotech[/strong][strong] - what we think it is:[/strong][div][br]As seen as Iron Man’s armor in Infinity War (and as Black panther’s suit in the overly CGI Black Panther movie) nano tech is far more advanced than what we presently have. Nanotech, to be able to do what we see in these movies would have to do the following:[br][br][strong]Replication: [/strong][br][br]If nanobots can assemble themselves (and the other nanobots) into all sorts of designs, then they could actually create a duplicate of themselves. One of the huge advantages of nano technology is that the devices can replicate themselves. And, in theory if you put ALL of the effort and energy of these devices into ONLY replication then it happens on a truly exponential scale. Meaning that a small number of them could duplicate in a short period of time, then those new ones join in to duplicate,,a dn so forth. so, 2x2 = 4, 4x2=8, 8x2=16,16x2=32, 32x2 = 64, 64x2=128, 128x2=256, 256x2=512, 512x2=1024, 1024x2=2048.[br][br]So, if it takes a minute to replicate (that may actually be really slow for nanotech), and you start with only 2, the second minute gives you 4, then 8, then 16, then 32, them 64, etc. so that means if you start with only 2, eleven minutes later you have over 2,000 of them. If you let them go for just another ten minutes or so you then have over TWO MILLION. Obviously you need the space and the resources for this. But that’s how you build your nanobot repository before you store it in your chest. That’s also how you accidentally wipe out an entire civilization, accidentally.[br][br][strong]Radio control:[/strong][br][br]Each bot has to be able to be directed by a central control to perform a task. in the case of these kind of robots they are not directed to perform each step of the task, but rather participate in a swarm, or sub swarm, or even sub-sub-swarm towards a goal.[br][br][strong]Nanobot[/strong][strong] OS:[/strong][br][br]Each bot has to have preprogramming of a basic sort - an operating system it can boot into. This basic operating system allows it to understand it is part of a bigger whole, how to replicate, how to use resources, and how to form swarms.[br][br][strong]Memory:[/strong][br][br]The bot needs a decent amount of memory. Even if we have all of the designs, and blueprints, and even steps to build something stored in the central control unit, you still need a surprising amount of memory in each device.[br][br][strong]If I was tasked with designing it[/strong][br][br][br]Here are some things you (and honestly those that are in the field) may not have thought about.[br][br][strong]Attrition:[/strong][br][br]As a nanobot weakens, it passes a threshold of usefulness. At this point it offers itself - along with other failing nanobots - to a nearby nanobot. Based on the tasks at hand and priorities the healthy nanobot goes to work to disassemble and then recombine the weak bots in to one or more new, fresh bots. Your body does something similar to this, and if our ‘garbage collection’ is too slow then we get cancer.[br][br]So if you are in battle and a bunch of bots get damaged through hits, or use, excessive heat, etc, then a swarm of bots would be constantly creating new ones. Or in the case of one offs, a nearby bot would self-assign the task.[br][br][strong]Massive power requirements:[/strong][br][br]Each bot would require and utilize massive amounts of power - power far beyond the energy density we can create now. This is very similar to the original iron man suit, in that would use broadcast power as energy, thus removing the need for an onboard power source (other than a minor capacitor-like device to buffer incoming power).[br][br][h3]Broadcast Power generator:[span style="font-weight: bold;"][/span][/h3][div]If it were up to me to design the swarm, I would device a power converter that would use broadcast power as energy, thus removing the need for an onboard power source (other than a minor capacitor-like device to buffer incoming power).[br][br]A nearby (presumably in the housing unit) power generator would generate massive power, and broadcast that, extremely short range to the bot swarm.[br][br]Remember the Chitauri, or the useless droids in the prequels of Star Wars? Remember what happened when they were cut off from the controlling ship? Same would happen with the swarm if you stopped broadcasting power to them.[br][br][h3]Consumption:[span style="font-weight: bold;"][/span][span style="font-weight: normal;"][/span][/h3][p]The opposite of the Attrition attribute, the consumption command would allow the bots to break down and “consume” material. The ability to do this allows for many benefits including:

[br]1.Repair of existing bots[/div][div][br]2.Creation of new bots to increase the size of the swarm (see above when we first address this)[/div][div][br]3.Creation of special and exotic functions that require those materials[/div][p][br]

[div]4.Creation of a substance - in other words the bots create and dispense a liquid, gas, solid. We see this when Tony seals the hole in Ebony Maw’s ship, and later when he heals a wound.[br]The bots essentially get to play a game of Alchemy - they get unlimited power, heat, some base materials (whatever the existing swarm is made of), the gasses in the atmosphere and whatever is nearby to play with. Then they combine and create new stuff, and create new stuff from that.[br][br]This is a devastatingly powerful ability that can be used as a weapon.[br][br][h3]Propulsion:[span style="font-weight: bold;"][/span][/h3][/div][div] What everyone gets wrong about nanotech is that these things are all tiny little insect like devices with multiple legs for crawling, or with claw like appendages to grab blood cells and stuff like that.[br][br]Do you remember when Maw showed up and Tony tapped his chest activating his suit? How long did that take? Perhaps no more than 10 seconds? The particles “crawled” all over him (and themselves mostly) to spread out and create the various parts needed to form the suit. 10 seconds. This could now be done under the best conditions with legs and appendages. The amount of heat generated by the movement, the inefficiency of traversing the changing, moving landscape of the other bots, let alone the assembly of the various devices, subdevices and substances would cause that very first appearance to be impossible. Nanobots can’t have legs, or arms, or wheels, or cute little teeny tank treads.[br][br][h3]Exotic Propulsion:[span style="font-weight: bold;"][/span][/h3][/div][div] They have to be propelled like a drone, or a spacecraft via antigrav technology so that they can accelerate and decelerate and near impossible speed, make 90 degree turns and in generally move unburdened and unaffected through three dimensional space, over other bots, clothing, and unpredictable landscape. Imagine a swarm of them instantly accelerating, stopping cold in position and then locking in.[br][br]The propulsion would also be used to maintain position, which would allow the formation of exotic devices.[br][br][h3]Exotic Devices:[span style="font-weight: bold;"][/span][/h3][/div][div] Right now we make stuff out of metal, plastic, ceramic, etc. We pour stuff into molds, we 3d print them, we assemble them with pieces and fasten them with rivets or screws or weld points.[br][br]Imagine if you could have a section of a device show up, and just sit there, held into place my a tiny field of adhesive gravity. Not ideal, and certainly not meant for long term, but if a piece or section or part needed to be there and just stay there for a short while (like say during a two minute battle) you could just do it. Need a tiny piece to rotate, or flex a certain way now and then but don’t have a way to mount it? You don’t need to.[br][br]So, if we could create particles that are insanely tiny, give them antigravity propulsion, a surprisingly fast computer with equally surprising storage, the ability to be controlled wirelessly, and broadcast power converter, and then go on to invent various swarm templates for attrition, consumption, conversion of matter, creation of devices normal and exotic we could have nano tech like Tony has in Infinity War.[br][br]And, like last time, I’m sure I missed something. [br][br][h3]One side note:[span style="font-weight: bold;"][/span][/h3][/div][div] In the battle with Thanos on Titan, Tony reaches a point in which he is attacking with his hand repulsors and some of the particles leave his leg. It seems like we are to understand that those particles are ‘used up’ as he is trying to hard to defeat Thanos. This gets back to the attrition/consumption concept. However, after the battle Tony is covered with a smattering of half formed designs on his upper body, like he has run out of particles. If the particles are made of exotic materials that cannot be gained from the environment then he would indeed run out.[br][/div][p][br]
