thats a hell of a lot of energy

What about using mirrors as a shield to deflect the lasers? Like the soldiers wear mirror armor for protection.

even if you had optically perfect mirrors the soldier would be rather noticeable on the battlefield and as soon as the optical mirrors pick up any dirt etc their protection fails. better to go for some manner of ablative or absorptive surface.

If the windo is in space, then rupturing the "window" would let the Plasma escape at the speed of heat into the vacume!

are you sure this is what you were trying to say? if so what is the speed of heat in a vacuum?

I wasn't going to comment on this since I believe Shooter2k must have meant something else.

Since heat in a vacuum is just electromagnetic radiation travelling at speed c (speed of light) it is impossible for objects with mass, such as ions, to travel at sped c unless they have infinite kinetic energy?which is impossible.

The window would not disperse just by being penetrated but small sections might, if the kinetic energy of the attacking object was great enough to overcome the repulsive force from the ions, be able to be pushed out.

Remember this is not a plasma "gun" or "explosion" this plasma is tightly confined to an area of space by an electromagnetic field.

Yes it is.

It?s an extreme example to illustrate my point. However I could have used even more insane conditions such as a Quasar... just to ram home the point, but theres no need to over do it now is there

If you've got an electromagnetic field strong enough to hold high-pressure, superheated medium (could be anything, really, but if you have that much energy knocking about it will most likely be a plasma) then I would have thought that the EM field would be amply strong enough to stop any KE round, so filling it full of superheated medium seems a bit redundant.

This article http://www.acceleron-enbeam.co... seems about the best technical information I could find about plasma windows. It's from May 1998, but current articles indicate that the first applications are just preparing for market. The slow speed of innovation would indicate substantial problems with scaling the technology up.

The window in the article used 5kW (100V x 50A) of power for a 2.93mm diameter window, or about 60kW/cm².

This power level seems impractical for armor.

speed of heat?

I like the term, sounds good

it should be the average molecular velocity in the medium.

so if your plasma is at silly degrees C, then its going to be a big number

"How would it be possible to have laser guns in the future?"

Laser weapon? Yes.

Laser gun? No need.

Gun(KE) guns are good. If you need a preformance increase the first place to go is improved propelents that maintain cylender presure longer and in so doing impart more energy into the projectial with the same tube. It's like putting rocket fuel in rater than explocives. Then you can use electrothurmal tec to shoot your electricity throught the propelent to both increase the presure and to get good control of how much presure you have when the projectial is at any given point in the tube. Some people like railguns.

You can also make projectiles that give you a greator effect on target with the same weapon and very simeler ammo. The idea is to do less tisue damage near the impact site and get the energy around in the body. It is not how big a hole you tear in a membrain in the body but how many membrains you tear holes in. Simple example is a subcaliber projectile that has low drag in the air. When it impacts the nose fishhooks. It contiues to travle for a long distance because the drag is not increased that much but it travles in a chaotic curve. It could go in the arm and come out the leg. If you want more predictability put 12 tunstin needles with triangle crosssections and bends at the front end together to make your bullet. Then have them wraped in a matieeal that give you gas seal and riffling contact in the tube/barrle. It also gives you the balistice before impact or going throuch light folage or canvas tents. The impact with a body shaters the outside of the bullet and frees the needles.

Blowgun darts are a mature tec that could be combined with paintball gun tec and s ammo feed system. Then you just need to pick your pharmasutical payload. Should I set my weapon to sleepy or LSD trip? This weapon could be slung under a normal gun that could shoot throught doors or car windows.

So if you want more effect on target you can make much smaller changes than going to lazers.

Lower energy lazers that effect cameras and eyes are out there now.

Anyone who wants a talk on sound weapons for a novle can talk to me for a consulting fee.

The speed of heat has two meanings;

1. **** fast in a jet with after burners lit and 2. The speed of brownian motion of indavidual atoms in a fluid. (It is one of those very technical and secrit terms only used by the geekiest of super nerds to other geeks and some of the more brilliant nerds inside the scientific comunity!)
