Interesting Gauss Gun Site by ehass on Thu, Dec 5th, 2002 18:00:01 UTC

I found an interesting site with some info on the Gauss Gun. Just thought I'd post it if anyone is still interested... Click Here

particle gun? by spartan on Wed, Dec 4th, 2002 02:00:00 UTC

I got this idea while designing a sci-fi spaceship. It's a gauss gun that shoots particles rather than anything solid. The basic idea was to replace the magnets in an old-fashioned gauss gun (such as the ones built in physics class in highschool) with magnetized gas (particles). Initially, a wave of particles would be accelerated electrically into a vacuum tube where gas would be simultaneously injected in hundreds of positions. As the wave hits the gas the particles collide and accelerate towards the next gas inlet. Since particles are used instead of magnets, the integrity of the "magnets" would not be a limiting factor. On the other hand, even heavy particles should be accelerated to HIGH speeds to have an impact. My physics knowledge is very limited so, if this forum is active anymore, could this weapon actually work? Logged here, hoping to find information about gauss guns that use coils, porbably gonna try and build one at our summer place ;) p.s. In case there are typos, it's because I'm far from a native speaker (finnish) :)

Well, an interesting idea although I'm not sure that I can picture what you're saying. Can you elaborate some more? Thanks.

Home Made "Magno" Launcher by chronoenigma on Sun, Dec 2nd, 2001 06:01:08 UTC

How would one shoot somthing say, as small as a bb threw somthing like a drinking straw? Electromagnatize a spring inside the straw with a magnatized bb at the bottom of the coil forcing the bb to travel, spiraling along the "spring threads", and gaining speed and then out the end??

Re: Home Made by tomh on Sun, Dec 2nd, 2001 11:00:02 UTC

Our gauss gun plans acutally use a soda straw to shoot a BB. So, I might as well not say anymore or we would end up just giving the plans away for free! However, I'm not aware of this other method you describe with a spring.

Re: Home Made by evev on Sat, Dec 7th, 2002 09:00:05 UTC

a soda straw not usable for real coil gun. I try it. Coil hotting. Straw melted. You can see pfotos of my coil gun with bronze foil burrel on site: Click Here Evgenij.

Re: Home Made by Hobson on Sat, Dec 8th, 2001 04:02:03 UTC

I imagine this straw gauss gun is made one of two ways: Linear coil Linear pull-push phases In a coil gun, there are stages of coils that are made into electromagnets, which pull the projectile in oscillations.(on long enough to pull, then off while the next coil is turned on). Coil guns can be breech loaded or muzzle loaded, I suppose. In a push-pull, which are muzzle loaded I assume, a series of electromagnets with intermediate non-magnetic items build up speed by smacking into one another till power is built up on the loaded projectile, which fires(normal magnets can be used, depending on design).

Gauss Gun by WE on Fri, Dec 8th, 2000 08:01:00 UTC

While filming in a electrical motor factory we came upon a secret project. It was an electrical motor which followed a rail. It was a replacment for an elevator cable system. The advantage was that it could not only go vertically, but also horizontally. Do any of you know more about this?

Re: Gauss Gun by tomh on Fri, Dec 8th, 2000 09:02:02 UTC

I can't imagine what part of rail gun technology would be used here - but that isn't to say there isn't something. However, the application of what you describe might be some kind of new improvement on a linear motor which is used commonly to position X-Y tables or for fine precise postioning.

Re: Gauss Gun by camp on Sun, Dec 10th, 2000 04:02:01 UTC

yes they are going to need these for new building designs the elevators move horizontally as well as veritcally but I am not sure if any are in service yet.

In the next few weeks or months, we intend to release all our DOS software. You can see the beginning of this now under Products/DOS software - FREE! More important than these products is the underlying development system used to create them which we shall make available too. This is a powerful applications development system which is still very useful today, especially in light of the immortality DOS has been given by products such as Free DOS, DOSBOX and QEMU.

Re: Supreme Court by tomh on Sun, Dec 8th, 2002 01:00:00 UTC

Unfortunately, I was out of state when this finally came to a head and was decided. I could spew reams about corruption (and I have - see Click Here ) but the fact is that we ourselves are to blame for letting things get this bad. We have allowed decades of legislators to sell us security and fixes for problems which we should have taken responsibility to handle ourselves as individuals instead of trying to get fix-all laws, committees and agencies which apply to everyone. These laws and their infrastructure are so thick, so compounding and confusing that leagues of experts can not agree on their meanings anymore. When that happens, your have what I call "corruptable interpretation". In other words, since no average citizen can understand the totality of the laws, we appoint experts to interpret those laws. Those experts are corruptible either by direct lobby, threatening influence or through misleading and deceptive information. The governor was quite clever, using Nevada's balanced budget law, he got the legislature to approve the budget before they thought about funding it. Then, he threw that gap back on them. I noted, according to the RGJ, that a majority of expense in the budget was allocated to police and fire. It's a shame that the public accepts these expenses without question. There are so many laws which need no enforcement. So many laws in which we are better off without enforcement. And, so many laws which were designed to prevent events which are statistically irrelevant. Were I on the legislature, I would have proposed a significant cut in police funding. To offset that, I would propose an increase in citizen's policing rights. And then give the police departments more opportunity to use volunteer citizen help. Many policing duties do not require the intense training police officers undergo. Cell phones and eyes for watching go a long way. As for laws which they try to enforce, for example, I don't feel that most citizens need protection from prostitutes or more so, the "johns" they service. The "stings" they set up are a waste of taxpayer money and destroy peoples lives who are otherwise productive citizens. I am quite sure there are many other such opportunities for cuts in other agencies and departments which do not affect schools or educational services. The puppet masters are so arrogant these days, they could care less whether or not their audience even likes the show.

Re: Gauss Gun by tomh on Sun, Dec 3rd, 2000 01:02:03 UTC

I don't really know where this stuff stands anymore. The thing to remember is if you heard about it, it's probably old. If it's not old, then you heard about it because it probably doesn't work very well. If it works well and its new, don't count on hearing about it until its old - :) But, remember in all of these that they are not free energy machines. The amount of energy released in a .22 cartidge is probably on the order of a Kilojoule, but I would invite comment from a physics expert here. That's a pretty damn big electrical energy device (like a capacitor) compared to the size of a .22 cartridge. Energy storage technologies are the thing to really keep your eyes on because this gives us clues about what the big boys may be doing.

A friend of mine told me that the military had recently succeeded in making a practical gauss gun. The weapon is supposed to be capable of downing aircraft from the ground. He also told me that video of test fires of the weapon is available online but I don't know where. As for the mass driver, I don't know what happened to earlier efforts, but nasa is funding to conduct a preliminary study to see if a mag-lev driver to space is feasible. This is a somewhat recent development. Check out Scientific American's website for information on this. Search for "halbach array train". The article is from ~1-2 years ago.

large version by futurewealth on Thu, Oct 31st, 2002 03:01:04 UTC

I seen a site with pics of one in use. It was actually a rail and gauss guns. there were several sizes. a small version about the size of a small ice chest that fired at a high rate, not sure of the velocity. the rail gun was on the back of a flat bed truck and fired 1gm projectile at just over 9 miles/second 16,000 m/s. stated it would fire a 1.6 kilogram/ 3.5 pound projectile at about 2800 m/s or 1.6 mile per second. This would be an awsome application for a tank, could fire smaller non-explosive rounds further and at high enough velocity to tear the toughest tank apart. and with out the need to hull large amounts of explosive materials inside the cabin with the crew.
