Vince, when you pass that much current through something it produces a tremendous amount of heat. Tends to vaporize things, like the "gun" itself sometimes. Look up "arc flash" >> en.wikipedia.org/wiki/Arc_flash
That's why I have to wear a special uniform at work.

Pretty interesting bullet, also! Wonder why that shape?

Bushy, I work with industrial machine controls. Controllers, sensors, actuators, motors, hydraulics, pneumatics, etc. The current buzz word is "mechatronics". A blend of electrical and mechanical stuff. The arc flash uniform is because we're working on up to 600 volt systems. Occasionally we have to wear something like this >> www.labsafety.com/SALI...CID=9PP001
Slim, that shape fits in the rails they are using now. They're just testing the concept of the rail gun itself. The final actual projectile would have to be a lot more streamlined to do what they hope to do with it.

O K...So why didn't you say you were a "electromechanical engineer"...

Bushy, I'm not an engineer, just a technician. Or, as I told one rather pompous management type, "I'm just a peon. However, I am the peon that makes this s__t work!"
Yote, TRBL, that arc flash clothing sure is HOT, isn't it! Especially in a plant that isn't air conditioned. I think the highest voltage we have in the plant is 3200 V. We do have some much higher voltages but they are low current stuff. Corona treaters for the paper/film/foil going into printing presses.
Boy, we wandered off subject on this thread, huh!
