Hi, /k/! Curious visitor from /v/. I've been shooting

>>23210254
Yeah.

On ships.

>>23210254
>why haven't we advanced the more futuristic weapons by now
Because using gunpowder to shoot metal bits at other people is far more cost-effective.

Energy source.
Railguns require a lot of energy.
Not to mention heat management, those experimental railguns get their barrels ruined after a couple shots.
At that point, its just easier to lob missiles and shells at whatever you want to target.

the technology either doesnt exist or isn't practical in a small arms form factor.

>Sure, we have super-powerful conventional weapons that propel metal bullets at very high velocities, but those aren't as exciting, are they?
what are you, some kind of faggot?

>>23210261
Really?
What can they do, what are they used for?
Is it just experimental stuff or real working weapons?

Is this nigga serious.

I don't know, the concept of shooting someone from so far away that you don't even have to be in the same neighborhood as them, and with such momentum that winds or body armor become irrelevant, sounds useful.

Come on now, I was just flavoring the post.

yeah, but it's a giant ass cannon mounted on nuclear ships.

>>23210254

The size of the battery you would have to carry to have even one shot would be gigantic

None of the railguns in development are intended for nuclear ships.

Which you can do perfectly well with a missile/bullet/whatever the fuck thing that isn't a crazy huge stationary weapon.

Alright, so the main issues (which will likely be a permanent hurdle) are - a) power source practically makes this a huge stationary weapon, b) the forces at work make it impossible to create a stable version, and c) it's not cost-effective compared with existing firearms.

OK then, I'll go back to reliving my dream in Quake Live. Thanks, all.

sam barros made a few rail guns, and coil guns, and electrochemical guns, and microwave guns, and a fucking cannon that shoots d-cell batteries at twice the speed of sound.

His more advanced rail gun shot pretty quick, i think it was around the speed of sound, can't be bothered to look it up myself but it was powered by a pretty big bank of capacitors. And it blows itself apart half the time when it fires.

Railguns are a thing, but theyre not man portable

looks like something ratchet would strap to his arm, not sure how he'd recharge those caps though

Energy storage is the big one. We can just store energy with greater density in gunpowder then in a battery, after all.

A solvable problem.

Recoil is the next one. You can just use so much power. A electomotive weapon can more efficiently accelerate a projectile then a chemical weapon due to the smoother, better controlled acceleration and lack of hot gasses ejected, but a human can still deal with only so much recoil. 67 joules of recoil energy is more or less the limit.

So sorry.. a shoulder fired gun that can blow apart a tank with kinetic energy just isn't going to happen.

But you could do a weapon that sends twice the energy of a modern rifle with the same recoil. It's certainly possible.

It won't be cost effective for a long time. The materials tech just isn't there.

It's like his brain just doesn't care and he's moving that path and that path only.
Not like there's a thing you can do.
