Rail Guns Closer to Reality

emtboy9 writes "Yahoo News is reporting that scientists at Sandia National Labs have created a magnetic pulse gun (rail gun) that can accelerate small aluminum plates at 34 kilometers per second, faster than the Earth travels through space. The accelerated plates strike a target after traveling only five millimeters, or less than a quarter-inch. The impact generates a shock wave -- in some cases, reaching 15 million times atmospheric pressure -- that passes through the target material turning matter into various states almost instantly (solids into liquids, liquids into gas, and even gas into plasma)."

    "a magnetic pulse gun (rail gun) that can accelerate small aluminum plates at 34 kilometers per second"

    We were taught this at the age of 14 - what were you doing?

    Acceleration is measured in distance per second per second. 34 km/s is a velocity. So did you mean it accelerates it to 34 km/s? Or did you actually mean it accelerates at 34 km/s/s? This is /. were pedantic nerds with nothing better to do hang out, not CNN.
