Ring Projectile - The Mass-Driver 4.5-inch diameter 'ring' projectile, which is utilized to ride a wave of magneto- inductive current down the 2-foot barrel of the device. The ring is not a required shape, and conventional projectiles have also been successfully tested.

The Military - Previous attempts by the US Government to create lighweight EM-weapons have failed because they were attempting to fire heavy projectiles such as tank-shells.

Unfortunately, the efficiency of EM-weapons decreases with the square of the projectile weight, which means that while heavy projectiles are nearly impossible to accelerate, lightweight projectiles offer better acceleration than normal bullets.

The Mass-Driver is a 2nd-generation electromagnetic accelerator developed by Information Unlimited in Amherst, NH. It's capable of putting a 4.5 inch (1/4 pound) projectile through 1-inch thick wood with projectile speeds exceeding 300-feet per second. It packs a whopping 3000+ joules of energy into an ultrashort pulse -- accelerating the projectile from 0 to 204 mph in milliseconds. click here

How Does It Work?

Mass-Driver technology is based on Lenz-Law inductive-repulsion, rather than the more traditional Lorentz-force used in traditional railgun designs. Instead of passing current through a rail-system, the current is pulsed through an accelerator coil, which in turn creates an opposing magnetic field in the disk-shaped projectile.

The capacitor shown above is used to create a 3,000 joule pulse that instantly accelerates the projectile-rings to high-velocities in excess of 300 feet-per-second.

The projectiles weight 3.7 ounces each, and measure 4.5 inches in diameter at 1/8 inch in thickness. At maximum velocities, they've been tested to penetrate wood, drywall, particle-board, and light-metals.

Keep in mind that while the Mass-Driver is fully-functional, its still definitely in the prototype stages -- it functions great in a lab or other carefully controlled environment, but can be highly-dangerous if not used in accordance with safety precautions.
