New Gun Fires 'Laser of Lead'
SYDNEY, Australia -- It may not be ready for George Bush's "first war of the 21st century." But it may well be ready if there's a second.
In perhaps the most audacious upgrade of high-speed weaponry since the introduction of the Gatling Gun, Australian inventor Mike O'Dwyer has developed a machine gun that can fire bullets at a rate of 1 million rounds per minute.
Firepower like this is causing the U.S. and Australian militaries to sit up and take notice.
Both are funding deeper research into O'Dwyer's ideas, which he cooked up in his garage during more than a decade as an Australian retail store executive.
Osama bin Laden, however, needn't worry. The research is long-term and isn't expected to yield any new lethal weapons anytime soon.
Even so, the implications of the new technology's ability to change warfare are immense. And somewhat amazingly, the theory is pretty simple.
Rather than use mechanical firing pins to shoot bullets one by one, O'Dwyer's gun holds multiple bullets in the barrel -- one behind the other.
Electronic charges set off in different parts of the barrel, just fractions of a second apart, fire the bullets in blindingly fast succession using traditional gunpowder.
The result is akin to a laser beam of lead and it offers several advantages over a regular machine gun.
First, the new gun is solid-state and electronic, meaning there are few mechanical parts to jam.
Second, more bullets can be fired with one squeeze of the trigger before the gun recoils.
But perhaps most remarkable of all, the unique ballistics of firing projectiles close together means that the bullets farther back of the pack actually push those in front of them, thereby increasing bullet velocity.
O'Dwyer has filed for at least 58 patents on the invention, and the U.S. and Australian militaries together have put up roughly $50 million for further research.
In the United States, the Defense Advanced Research Projects Agency (DARPA), the central research and development organization for the Department of Defense, is engaged in several studies of the technology, says Jan Walker, a spokesperson for the agency.
DARPA's primary interest is developing a high-performance sniper rifle for special operations, Walker said.
"The technology offers high accuracy, low weight as compared to a .50 caliber rifle, increased lethality, a high rate of fire and electronic controls," Walker said.
Just how lethal? That depends on how many rounds you want to fire and how many barrels you want to put to use. In a test firing of 36 barrels, lashed together and firing full bore, the gun reduced a series of 15 wooden doors to toothpicks in just two-tenths of a second.

How in blazes would you store ammuntion for soemthing that needs a million rounds a minute??!!
Potentially the world's most powerful automatic weapon, Metal Storm uses a system that combines gun barrel and magazine, so that the only moving parts are the projectiles themselves. Other automatic weapons have a magazine with bullets that are mechanically loaded into the barrel, but in the Metal Storm weapon, ammunition is preloaded and stacked in the combined barrel/magazine.
The bullets are fired electrically to generate a torrent of lethal force (up to thousands of rounds per second), especially with systems using a multibarreled configuration. This technology can be used for all types of munitions, and with no other moving parts, jamming is never a problem. Seen above is Metal Storm's remote-controlled Redback 40mm weapon system, recently introduced as a devastating counter to all types of threats.
It's called Metalstorm, and it's been pretty much something of a flop. Not much interest has led to the company being nearly bankrupt. They currently have enough operating funds to last until 2007, but beyond that is questionable.

1, How do they control rate of fire?

2. How do they prevent the barrels from overheating?

All the ammunition is stored in the barrels. You stack it round ontop of round. It uses electromagnetic propulsion IIRC to shoot the rounds out the barrell, so that they don't explode like a regular bullet and set off all the other rounds they're stacked on.
