If you happen to have say, 300 microwaves kicking around between you and your friends, it turns out that you'd have a large part of the ingredients necessary for a pretty substantial weapon. That is, according to two New Mexican inventors, who recently filed a patent for a "high-power microwave system employing a phase-locked array of inexpensive commercial magnetrons." Translated into English that basically means that these guys claim you can combine the magnetrons (the bits that generate the actual microwave that cooks your popcorn) from a bunch of consumer-grade microwaves and tweak 'em a bit to develop a megawatt-level death ray, or in military/legal parlance, a "directed energy weapon system." Yeah, we've seen energy weapons (or tools, if you prefer) before, but this is probably one of the first times that we've seen ordinary kitchen technology more complicated than a knife turn into a seriously lethal weapon.

If any of our peeps at Tel Aviv University have been noticing some suspicious holes around the campus lately, here's your culprit. It seems some researchers at the university have created a microwave drill that can easily bore holes through concrete, glass and other materials without leaving so much as a trace of dust left behind. It works by heating up the material to a toasty 2,000 degrees Celsius (over 5,400 degrees Fahrenheit), which softens the material enough for a metal rod to be pushed through it. Like any good death ray, however, the microwave drill has its weaknesses. For starters, the beam is unable to penetrate steel or sapphire, and there's also the small issue of microwave radiation, which could have some nasty consequences for the poor soul stuck operating the drill. According to the researchers, however, a simple shielding plate should be enough to protect anyone in the vicinity of the monstrosity -- maybe, but are there enough steel plates to protect us all if the device falls into the wrong hands? Like ours?

We're rather impressed with the US Air Force and their Starfire project. It's not every day you get to build a death ray on a desert hill in New Mexico and write it off as a scientific endeavor. The premise is that since the atmosphere diffracts light, messing up the view of ground-based optical telescopes, the Starfire shoots a laser 56 miles into the mesosphere and measures the distortion to adjust the telescope optics. Images from the Starfire are 40 times more accurate than regular, but the laser technology is coincidentally multi-purpose: "We don't hide the fact that it could help build an anti-satellite weapon," says the installation's chief, "if you choose to do it." Our thoughts exactly.
