US Military unveils heat-ray gun

[Saeveo]

50 Degrees c?

Pussies. I lived in constant 50c for 3 months when I was staying with my Aunt and Uncle in Alice Springs.

Yeah, but that's air temperature. Your actual skin doesn't rapidly heat to 50C.

A fork. A fork will spark because it's pronged. Spoons hardly ever spark, unless they're particularly pointed or you have a very strong microwave.

Slightly off topic but,
seen what happens when you put a grape in a microwave?

Cool, but htey shoulda invented the "pie-ray". Turns your enemies into steaming apple and cherry pies! Tha'd make the war on terror, or hell wars in general, tasty.

[Jase]

Have you ever but a spoon in the microwave.

Didnt they like bust that Myth? They had like 3 screws in the microwave, but aslong as they werent spinning or touching some shit they didnt explode, or some shit.

Im sure they busted it becuase i wanted to do it, but mum yelled at me, even thou she was watching it aswell.

Assuming that the Bohr-model will suffice:

Then you have E=hf for the energy of photons, you can calculate the minimal frequency of light needed to strip the atom of one of its electrons.


No, and I don't really intend to, either. (A fork would have a larger chance of creating sparks, anyway)

Ok ill get back to you with the results as soon as I get free time.

It's not that dangerous I remember my lil bro butting ice cream with a spoon on the tub for some reason there was sparks but nothing went wrong microwave is still working till now.

[Azruelli]

I have a bad feeling about this development....
Like they're going to use this on US citizens sooner or later.. or another non-hostile country.

[samarjit]

US always had made weapons to sell to other nations or to rage war on other nation.... to which they have no reasons to say...

Screw the raygun

What about the railgun!!!

Abit on info {not BS}

"The United States Naval Surface Warfare Center Dahlgren Division demonstrated an 8 mega-joule rail gun firing 3.2 kilogram (slightly more than 7 pounds) projectiles in October of 2006 as a prototype of a 64 mega-joule weapon to be deployed aboard Navy warships. Such weapons are expected to be powerful enough to replace BGM-109 Tomahawk missiles at a fraction of the operating expense.[2]

Due to the very high muzzle velocity that can be attained with railguns, there is interest in using them to shoot down high-speed missiles."

Railguns as weapons

Railguns are being pursued as weapons with projectiles that do not contain explosives, but are given extremely high velocities: 3500 m/s (11,500 ft/s) or more (for comparison, the M16 rifle has a muzzle speed of 975-1025 m/s, or 3,000 ft/s), which would make their kinetic energy equal or superior to the energy yield of an explosive-filled shell of greater mass. This would allow more ammunition to be carried and eliminate the hazards of carrying explosives in a tank or naval weapons platform. Also, by firing at higher velocities railguns have greater range, less bullet drop and less wind drift, bypassing the inherent cost and physical limitations of conventional firearms - "the limits of gas expansion prohibit launching an unassisted projectile to velocities greater than about 1.5 km/s and ranges of more than 50 miles [80 km] from a practical conventional gun system."[1]

If it is ever possible to apply the technology as a rapid-fire automatic weapon, a railgun would have further advantages in increased rate of fire. The feed mechanisms of a conventional firearm must move to accommodate the propellant charge as well as the ammunition round, while a railgun would only need to accommodate the projectile. Furthermore, a railgun would not have to extract a spent cartridge case from the breech, meaning that a fresh round could be cycled almost immediately after the previous round has been shot.

Currently the U.S. Navy is using the rail gun concept for a cheaper and more effective projectile capability, as stated by the January 29, 2007 edition of NavyTimes

[edit] Tests

Full-scale models have been built and fired, including a very successful 90 mm bore, 9 MJ (6.6 million foot-pounds) kinetic energy gun developed by DARPA, but they all suffer from extreme rail damage and need to be serviced after every shot. Rail and insulator ablation issues still need to be addressed before railguns can start to replace conventional weapons. Probably the most successful system was built by the UK's Defence Research Agency at Dundrennan Range in Kirkcudbright, Scotland. This system has now been operational for over 10 years at an associated flight range for internal, intermediate, external and terminal ballistics, and is the holder of several mass and velocity records.

The United States military is funding railgun experiments. At the University of Texas at Austin Institute for Advanced Technology, military railguns capable of delivering tungsten armor piercing bullets with kinetic energies of nine million joules have been developed [1]. Nine million joules is enough energy to deliver 2 kg of projectile at 3 km/s - at that velocity a tungsten or other dense metal rod could penetrate a tank.

I totally already said that. Rail guns are the shit.

Still, it's no Rail Gun.

My little brother tried making nachos and cheese when he was 5, left the fork in the bowl of tortilla chips and cheese, and it completely destroyed our microwave. It went up in smoke. *shrug* I know it can fuck up the microwave in the right situation. I'm not about to try it myself, however I actually did stick something metal in the microwave not too long ago, being retarded.
I got a loaf of bread out of the freezer (we tend to buy them in bulk when they're cheap and store them for later lol frugal living), and decided to try and defrost it in the microwave instead of waiting for the bread to come to room temp on it's own. I completely forgot about the band of metal inside the twist tie on the bag. It burnt off all the paper of the tie, and burnt a hole in the bag, and also burnt my finger like a motherfucker when I went to get the loaf out of the microwave without looking. This was only after 20 seconds in there, too.
However, my bread DID defrost.

Putting CD's in the microwave is where it's at.
