The way I see it, at the moment it is the weapon that would benefit most from being a battlesuit-integrated armament. If the earlier-suggested "routing of heat through armor" is possible, it can be done with our new-model battlesuits as well; and it would certainly benefit from a large integrated power source - protected by layers upon layers of armor rather than carried as a backpack or something, providing a critical vulnerability point for disarming the battlesuit.
Integration into a battlesuit is something I considered, but it will basically mean that the whole suit is going to be "built around the gun", like the Hollander (though for a different reason). It'd be impossible to make it a snap-on/snap-off thing, the cooling system would permeate the whole machine, and damage to any part would potentially lengthen the cooling time. A potentially cool (heh) thing to do could be integrating a PEW on
each arm of the suit - since both charge simultaneously, and the cooling system is not practically limited to the same one-minute recharge time, you could theoretically be able to squeeze off two shots per minute, and have some reserve cooling power to keep at least one shot per minute if the suit loses a limb or three.
Infantry-portable version might be moderately useful as well, though, but it should probably remain bare-bones. And whether it means cold-plates or cooling system rests mostly on how heavy each of those variants would be. If practically the same, then - whichever is cheaper, I guess? Despite hating the UWM approach to powering everything by non-rechargeable batteries, I would probably agree that we don't so much expect a trooper to survive so long that lower running costs would outweigh production cost - and we'll want to have as many powerful weapons as possible. Then again, if the negligible price difference was hand-waved in the long run (as far as industrial manufacturing goes), it might be better just to stick with the cooling system.
The infantry version can't have the cooling system, lest the wielder is limited to crawling around. The weapon, as it is now, is pretty heavy. Adding a massive cooling system would be literally too much to bear.
I wonder though, might it perhaps be possible to cool the coldplates again, say, between engagements/missions? If yes, they might actually be cheaper in the long run as well.
Would chucking the coldplates in a lake or something cool them off faster? I'd imagine that the typical mission would have some form of faster cooling available to the enterprising soldier.
I'm sort of imagining that the coldplates aren't just dense plates at slightly below room temperature. Considering they need to keep the device at near absolute zero, I'm assuming they're either super-cooled and super-insulated, or use some sort of extremely endothermic chemical reaction. So while tossing them into a lake would stop them from being hot, it wouldn't make them cold enough. But being reusable between missions is definitely possible - in fact it's possible to re-cool them rapidly enough to make a viable defense emplacement that auto-reloads and auto-reuses the coldplates of several chain-firing PEWs, even though it'd be pretty large.
@ sean: are you speaking for Sword missions, or background sods/npc forces?
Both I guess, but just the Sword-mission perspective is good too.
I'll assume the first for the analysis: I don't think the compressed shot will be needed on most missions to justify making the coolant version standard on the infantry one. I'd go with coldplates (ammo, in other words) but let one have the option to switch to coolant system for extra money (on purchase or later on). Basically, make it as cheap as possible, but with an extra expensive option for those who really, really want it (like how one can replace the laser rifle's battery with a generator for extra cost, even though almost nobody ever shot his rifle enough to justify that investment).
I was asking about the Battlesuit version, but that answers the question too, I guess.
Coldplates it is then.
Is there any way to decrease the weight/bulkyness? I mean, heavy infantry weapons are a thing, but even those still need to ensure their wearer doesn't become a slightly mobile gun turret, when in an exoskeleton even a gauss cannon/PSL don't hamper their user in the way I'm picturing this thing would (based on your description).
Theoretically yes, by stripping the weapon of various parts or using an automanip to keep it cold, but it will require research.
If not, then I think it'd make more sense as either a vehicle weapon or a focused long-range one (a lesho for example can be heavy because mobility doesn't matter as much at the range it usually operates).
A battlesuit or a tank/gunship would do pretty well with it, yeah. Also, it fires anywhere between eight and sixteen times as far as a regular HEP while retaining the armor-penetration capability, so it can work as a semi-mobile sniper-ish weapon as well.
We might not have one-shot battlesuit kill infantry weapons (aside from spess mahic), but we do have some that can very much put the hurt on it/disable it, and that often seems to be enough. I mean, a regular HEP shot can knock it back and ablate a layer of armor, and should be capable of destroying any weapons it has on it, and a psl as well can do good damage (and has enough ammo and fire rate to also be usable against infantry).
Basically, contrary to what is often touted, we don't need massive overkill on most missions, and what we have (and is lighter, and perhaps cheaper) mostly fills the roles this thing could do.
Mmhmm. Yeah, the LESHO does pretty much the same thing, just with kinetics (though much more accurately and expensively, and/or explosively).
It does, however, sound like a good idea if really heavy targets could come up, like an AoW, but that hardly justifies lugging this thing around all the time otherwise. Say you just use a regular Hep shot with this thing. After this, you are left with a useless block for a minute, but it still weighs you down heavily, and said weight prevented you from taking a lot of other stuff with you. You're a sitting duck.
Yeah, that's a problem. A Battlesuit could theoretically have two mounted, one per arm, and would still be able to use regular weapons, but a regular trooper will be out of luck. That was something I wanted to address, but it seems it won't be that simple.
Finally, I wonder if, for infantry stuff, it doesn't make more sense to go for regular lasers powered by shards. I mean, a gauss rifle sized one-time laser has the power to
4.So propane tank sized shard strapped to a rifle. One shot with something like that is probably good enough to go straight through a battlesuit. The gun is gonna melt to molten slag in the process though.
And if we that to a cutting laser, I think we can get that kind of destructive power but still reusable. It might (might) not be as versatile, and it needs ammo, but unless you are facing a neverending onslaught of battlesuits, I think something like this might be more practical. Thought that depends of course on cost, which I don't know yet.
The weapon itself won't be too expensive I'd guess, it's absolutely single-use so it wouldn't make sense to make it expensive. The power cell would cost a pretty penny though, and the requisite shielding for a shard of that size would make it rather heavy. A reusable version would be heavier still, since it'd need to deal with heat the same way the PEW does. I could see it being more practical if you need to limit collateral damage though - i.e. if you crit-hit a battlesuit's pilot with the laser, you just kill the pilot, whereas the PEW will take out the whole cockpit, and likely scatter what little remains of the suit's torso to the four winds. It's really a MASSIVE DAMAGE weapon.
Once we consider use for a battlesuit or vehicle though, this thing might become more viable I'd think (since, as Nik mentioned, we could use the entire body to radiate heat, and those can carry more bulk while staying mobile). There is still the big problem of downtime though, and a minute per shot might be long enough to make the whole thing useless anyway. Have you asked if reload time could be deceased?
Yeah, I wanted to see if bluerad cells could be combined with coldplates to reload as one unit, basically allowing you to fire as fast as you can reload. Turns out you can't just up and power the HEP with a bluerad cell, but whether the HEP can be recreated in a way that allows to do so is... unknown. Which I take to mean that it's a job for some good old sciencing.
