      For weaponizing tungsten plasma, you already have the Casaba-Howitzer concept:       directing a nuclear explosion through a tungsten plate, which throws a plasma       cloud at high speed (as in, 3% of c). Only a few percent of the nuclear       explosion will probably        contribute to the energy of the plasma (the rest is wasted in destroying the       nuke itself and beaming all around), but a few percent of an enormous amount       is still pretty big.       Design it so it widens fast, and you can use it for nuclear external pulse       propulsion (a.k.a. Orion). Design it for a narrow cloud, and you have a plasma       thrower. The range is still pretty short (I wouldn't bet on more than one       kilometre), but it still        beats classical nukes hundreds of times.       It would be a space weapon, mind you. In atmosphere, it wouldn't make much       difference compared to a classical nuke (plasma would be stopped by air, and       the shockwave would be more destructive than anything else anyway).              Now, about putting the plasma cloud in a handwavium bubble. Basically, you are       freezing a nuclear explosion and throwing it at the face of your target so it       can burst there.       Many find it stupid, but I think that's fine as far as 24-carat handwavium       goes, though you have to keep in mind those questions - without creating even       more unanswered questions:       - If they have a strong enough bubble so it can freeze nuclear explosions, why       can't it be used in other applications - like a forcefield defence against       said explosion?       - Why don't the other side burst it by throwing sand clouds at it?       - How the hell does it get past air in atmosphere?       - Why don't they directly throw a a CH to explode at/near impact instead of a       fiddly bubble?       - At this tech level, why don't they have more efficient weapons anyway, like       lasers, particle beams, relativistic projectiles, grasers, micro-black-hole       launchers?              What I would suggest, for example:       - The handwavium bubble is derived from (and powered by) the explosion itself.       So it can only be generated by detonating a nuke. Also, it keeps plasma in,       not out.       - The bubble fails after being depleted, not being burst like a balloon.       Small, fast projectiles will go through it and take away a tiny bit of energy       (so it will slightly decrease its range) but only being out of range, or       impacting a massive object (       depleting all its energy instantly), will burst it.       - Air depletes its energy fast, so its range is extremely limited there - it's       more of an extended flamethrower, particularly with the intense beam of fire       it leaves behind it. Only for very well-protected weapon platforms, or they       will fry themselves        firing it in air.       - The bubble is harder to intercept than a solid object, as high-speed       projectiles will go through it       - They didn't invent it - they reverse-engineered the stuff of a previous,       long-extinct civ. In fact, they have no idea how it really works, and it was       probably never used as a weapon as they did have some way more efficient stuff       - so it's like cavemen        sticking a butcher knife at the end of a rifle. Not the original use, but       still better than a stone axe. Bonus: they can have as much/little handwavium       as you want, and an unlimited access to Raiders of the McGuffin plotlines.              Le vendredi 26 août 2016 00:33:52 UTC+2, MrAnderson a écrit :       > So, I was thinking about effect of plasma hit on human. In my variation of       plasma weapon, plasma is tungstenium or any other heavy metal, flies at 200       km/s, and is squeezed by handwavium powerful magnetic "bubble", that works in       vacuum and atmosphere.        So, except containing the plasma bolt, it's quite possible, right?        > Tungstenium is dense, bolt travels at high velocity, so can it give a       kinetic punch to target? If yes, how strong will it be? I don't know how dense       this plasma might be, need help with that. Bolt dimensions will be, let's say,       0.5cmx50cm cylinder.        > I don't know if there is even a way too calculate all of this...              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
