found a site youse mite like, i just finnished the capacitor bank, it sounds like a .22 when its shorted.

It gives me Sorry, this GeoCities site is currently unavailable.

sorry, try again in like 5 minutes, it done the temporeroly univalible thing for me too.

yes me aswell (message is too short)

yep did it for me to

Alright, alright we got it. It doesnt work... I dont think it takes 4 people to say this for us to understand it does not work.

it wasnt doing that yesterday.

it works for me it looks coowl. buth don't get it how it works. does it shoot a beam of light ore something?

thnx grts

well , when you put the high voltage pulse through the rails the foil vaporises into plasma, and creates a very strong magnetic field, shooting the plasma out.

How do you know wich way the foil will go?Do you think it is possible with 10v 650 000mf?

@Rambo: The magnetic field is generated following the cork rule (if I remember from years ago in Physics) you'll figure it out if you read PpowerLabs' articles on them: http://www.powerlabs.org/railgun.htm

@Benny: If the foil vaporises, the magnetic field will have nothing to pull. Plus, this is a KE (kinetic energy) gun. Energy=mass*speed. How much mass do you think a molecule of aluminium has? Hint: by far not enough to be used as a projectile unless it has speeds aproaching that of light.
As a side-note: Particles (albeit heavier than Al) have been accelerated to energies equal to a bullet. Yet these particle accelerators are as big as a city block and use just as much power. What I'm trying to show you is that a plasma gun like the one Benny is talking about would be REALLY, but I mean REALLY impractical. Railguns shoot solid proijectiles, period.

thats pretty cool

ok i will put this thing here cuz i need to look at it and it keeps running outta bandwidth

google cache is the best thing that has ever happened

with this plasma at least burn skin or ignite matches?

Yes, but only for 1/3 of a second and at limited range (perhaps 3 feet for the Powerlabs railgun). So having a quarter-ton 5-foot-long railgun to ignite matches 3 feet away is pretty stupid. You could do the same with 3 grams of gunpowder.

The site talked about graphite slugs. Sounds to me like industrial motor brushes (solid graphite ones) would make a great projectile. Of course, you'd need a pretty big railgun.

this rail gun he made is just to demonstrate how it works for a cheap price, it is really mad
