A revolutionary new "supergun" can actually fire 1 million bullets per minute, or 1 million grenades. This incredible weapon was invented by Mike O'Dwyer, an Australian scientist based in Brisbane.
China wants Mr. O'Dwyer and has offered him US$100 million just to move there. He declined the generous offer. The weapon is called Metal Storm, and can be applied to almost any caliber of weapon. The average rate of fire for an Uzi is a mere 3,000 bpm.
Very few firearm revolutions have occurred in the past 60 or so years. You could send out a cloud of bullets or grenades in 1-2 seconds. The U.S. military has successfully tested this device and production is expected in as little as 12 to 24 months.
