Power supply is an issue. According to this https://www.arl.army.mil/arlreports/2002/ARL-TR-2764.pdf (some research done for the army) you need about 6kw to fully supply any possible need for one suit. Now, two 240V lines from a house (the dryer plug) can supply this, or you can make a shitty, slow suit that runs off of a 4kw diesel generator strapped to the back. Then you can armor it like a son of a bitch and hope for the best. At best though, that's an engineer's garage project run on a raspberry pi and a mark 1 nvg taped to the front. Could be useful in a warehouse scenario where you can just have power plugs everywhere and don't need to be fast.

HOWEVER

I had another idea involving special weapons teams. You use the mule in vid related that carries a very large power source and maybe a couple backpacks. Two or even three guys with long cables are attached to it which a) reduces weight on the suit proper and b) allows a much better power source to supply these suits. Maneuvers are done together and the team as a whole is a heavy weapons team. One guy has the super heavy machine gun and the others are point men. You send these guys in to clear a complex while your regulars flank, provide covering fire, etc. Said heavy weapons team draws lots of attention and blows shit up- you can even hide the dog behind cover or behind a suit, and even have regulars use a suit man as mobile cover. At least until we develop the miniaturized fission reactors that would be needed for the required output, it is something that could actually work. Hell, you can even mount a vehicle weapon or even little automated point defense guns for shooting down rockets onto the dog for even more protection and devastation.

Incredible, that sounds exactly like what would happen with a DIVERSE AND STRONG engineering team at PROGRESSIVE ENTERPRISEStm, in my plan the mule was for carrying diesel stuff because of the massive inherent inefficiencies in that technology.

By the time we get the reactor tech we can hopefully mount one on each suit and have them jump like in starship troopers. At the very least we could get an array of subcritical multiplicator RTGs running off of Polonium 210 thanks to that delicious power density of 120 watts per gram, it really depends. Half life of that stuff is about 100 days so you're still gassing up a lot but maybe three times a year. The power is the weak link. Control is easy since Heinlein comes to the rescue again if you've read the book. NAGATIVE FEADBAK

Negative feedback. Many many pressure sensors mounted inside the casing of the suit, sets of which correspond to certain actuators per limb. Moving your arm up, for example, presses against the sensors which moves the arm, removing some of the pressure from the sensors- so movement continues only as long as you keep moving your arm. A simple example is the foot, you only need mount sensors in the toe as if you notice when tilting your foot up or down the toes go up or down the most, pressing on the corresponding sensors. All the body is doing is moving itself where it wants to be and the suit is moving just enough to get out of its way.

>>681457

Well, you know, I was gonna make a shitty joke about the one clip in evangelion ep. 16 where they deploy against leliel and the whole cable thing working just fine for them but after two fucking hours of searching for the desired footage and not finding it I think I'll just say

I guess it works with giant fleshbots

Like I said, I'm really interested in the possibilities of these:

>Due to the shortage of plutonium-238, a new kind of RTG assisted by subcritical reactions has been proposed.[42] In this kind of RTG, the alpha decay from the radioisotope is also used in alpha-neutron reactions with a suitable element such as beryllium. This way a long-lived neutron source is produced. Because the system is working with a criticality close to but less than 1, i.e. Keff < 1, a subcritical multiplication is achieved which increases the neutron background and produces energy from fission reactions. Although the number of fissions produced in the RTG is very small (making their gamma radiation negligible), because each fission reaction releases almost 30 times more energy than each alpha decay (200 MeV compared to 6 MeV), up to a 10% energy gain is attainable, which translates into a reduction of the 238Pu needed per mission. The idea was proposed to NASA in 2012 for the yearly NASA NSPIRE competition, which translated to Idaho National Laboratory at the Center for Space Nuclear Research (CSNR) in 2013 for studies of feasibility.[43][not in citation given]. However the essentials are unmodified.

Now, RTGS are normally one big unit but if you cut it in half and made two or even three small vertical tubes you can make it flat enough to sit as a backpack, maybe. Plutonium is the go-to for RTG but that has a power density of 0.54 W/g, while Polonium, despite having a tiny half life (100 days), has an amazing 120 W/g. My math on this is probably complete shit but even as a long shot it sounds feasible with enough engineering. Once the proof of concept is done it can just be made easier to produce and thus cheaper.

Totally agree with you on the plating/AP argument though.

Trash can EFP's when?

>>681563

Polonium 210 is a pure alpha emitter and thus is stopped by thick clothing, trees, dirt, rocks, distance, etc. Your other nuclear fuel is a stable isotope that does nothing without the polonium radiation being directed onto it. The radiation is a non-issue unless china starts making shitty illegal ones with unstable gamma emitting isotopes because their ant scientists told them they could get a couple percent more power that way or something stupid like that. The real problem here is that most RTG's can get at best an heat->energy efficiency of 10% which is complete wank, so the trouble is in extracting as much energy out of that heat as possible in as small a space possible.

>>681590

Well if you properly vent the hydrogen in case of a meltdown you won't get an explosion, at least, just a melted reactor that is hot in both temperature and ionizing radiation.

>>681614

Let's just go full retard and assume that each person wears a full rad suit as padding between him and the suit, obviously shaped to be effective in the armor. Now it's your enemies who are in trouble if they want to retake the ground!

>>681628

I'm working on a tabletop setting built on top of GURPS-lite where nuclear detonations/reactors caused demons to be able to get out of hell and now you can curse your weapons to scream and shoot fireballs, or make the magazine release with such velocity that it can cause blunt force trauma. Imagine Doom + STALKER, and there's power armor.

>>681643

You can pick classic demon rituals or even Christianity if you want, but the feature ability to pick is binding, which in combination with engineering skills lets you bully an imp into a mechanical or electrical system and achieve crazy results. Each thing gets one effect and one curse when bound. Some combinations:

>Parts that detach from device do so with such velocity they cause blunt force trauma; Item is also possessed by an anime high school girl that will behave so long as you date it.

>Parts that detach get set on fire; device will scream out in a squeaky voice whatever it is you are doing with it.

>Device no longer requires power to operate; Possessed by a long dead british admiral that can control it.

>Operating the device will cool it by 5 degrees F each time; Device is unlucky.

Detachable parts include bullets, use your imagination. General goal of the campaign is to loot stuff in order to achieve your character's personal goals so you can retire, then you make another character. Game is over when everyone dies at the same time.

>>681680

I guess, except set in the 1940's and probably ~~east coast America~~ ~~chernobyl~~ wherever you decide you want it to take place in the world, even Fiji if you can imagine them having a nuclear reactor.

>IT'S A RIFLE

See that's why you make the armour capable of jumping around like it had a super-powered pogo stick instead of just waddling everywhere waiting to get hit by an EFP. Go read starship troopers, it has an actually quite logical application of powered armour. For summary, they drop them on site from high altitude and then these things jump around everywhere dropping high grade munitions before nopeing out. The suits are capable of jumping ok enough without jets but they do have sci-fi jets with enough lift to mass ratio to make the suits capable of going over buildings.

>>682432

Never said our version needs jets, just being able to jump a couple meters and sprint fast makes for one hell of a moving target. Having fun defeating that without tracking munitions.

>>682453

F22 maybe, but the 35 is a disaster. Also didn't you pay any attention to the part of the discussion involving active power generation instead of just batteries? You're also presuming these will run off of lithium ion which are shit, so since this is a theoretical topic we can assume that they'll have ironed out all the kinks in golden nanowire and graphene batteries.

>>682488

Having a hundreth or a thousandth of a gram of that in a nanocage would sadly be the most practical power source. The problem is that when that break IT DOES GO BOOM.

I wouldn't mind a military republic or a national socialist state :^) Imagine George Lincoln Rockwell in charge, wew.

>>682552

So long as someone puts out a program that runs on a raspberry pi equivalent with a list of requisite materials (pressure sensors, servo type) all you'd really need is the mechanical knowledge to construct it and the money for the raw/fabricated materials. An age of self-made knights coupled with the breakdown of the state-only military sounds interesting.

>>682560

As I said, the power source remains the constant issue. I could imagine though that in a rebellion scenario a guerilla force in an urban environment with only lithium ion batteries could have 240v cables coming out of cooperating businesses into the alleys and such for units to recharge when they get a breather. Two of those can run a 6kw suit so while a battery bank with that output would be tricky it could be done. Military would have to cut power to a district or overcompensate on police to stop it and both are PR nightmares.

>>682560

On the flipside, police could have van units where the troopers are running juggernaut suits and standing in the doors for a constant power supply. As for suspension, just use this EM bose thing. Polite sage for double post.

>brains of tony stark

Already told you this predicates on having a plug and play controller for the programming aspect, that is the hardest part. Thanks to the internet you can rest assured there'll be a professer parabellum of power armour for the mechanical aspect. After that point you get workshops and knightly orders to surround them; at the very least the /fit/ will be able to join and have access to PA.

Electrically active artificial muscle tissue like they use in the power armour of 40k also has quite a bit of promise to it. Non-responsive nylon muscles can supposedly output the power of a jet engine in terms of force. (https://www.youtube.com/watch?v=Za0VeU9Ov7A)
