Using Microwaves to Drill Through Glass
Linux_ho writes "UPI is reporting that Israeli researchers have developed a drill that can melt a small hole in glass, ceramics, or concrete with no dust or noise. Nature.com reports that it doesn't work very well with good heat conductors or materials with very high melting points, but the researchers envision a wide variety of manufacturing applications, and possibly some medical uses as well."

Can it be suction-cupped onto a piece of glass to cut a perfect circle out?

Wow. Imagine the implications in major industry. It would be the ultimate glass cutter.
I suppose it also melts through bunkers and armoured vehicles?
I've always wanted holes in my windows.

...it works really well on Palestinians heads, too.
What kind of time are we talking about for the average hotpocket? I'm just thinking about the immediate benefits here.
to the F-ray.
So, the article was a bit misleading as the microwaves are not enough to go through.
using microwaves to melt things is hardly a new idea. I'm sure this has been mulled over for decades.
so are they going to use this to drill through palistineans?
Can it drill through fucking palestinian terrorists?
The article mentions that it can only drill to a depth equal to a quarter of its wavelength. Why is this?
.75, 1.25, 1.75 etc.
Surely it could also drill at depths of

I doubt that steel conducts the heat away too fast. I'd wager that the steel conducts the RF radiation itself. Just like this device has an antenna, steel would be an antenna too. Not exactly impedance matched, but certainly enough to prevent the steel from being heated except across the entire piece.

...Burglars and Bankrobbers Corp. raised it forcasts for the financial year 2003 after a R&D breaktrough.
I was doing the same thing over 10 years ago for my Master's thesis with a pulsed CO2 laser with ~500W time averaged output. What is the advantage of using a microwave beam over a CO2 laser?
What a great way to make holes in complicated glass pieces. I see a brave new future for the science of "pipe" making.
Stoners of the world unite ! Yay for those ingenious asians
Is a laser really that much more expensive than one of these? I mean, they've been around for 30+ years now, havn't they? I bet this doesn't turn out to be so much more cost-effective in the short run, at least.

I once went there with a woman and smooched her all over, near the menza and the Mexico building. It was so fun! Luckily nobody passed near us.
I guess jewlery stores will now use transparent aluminium instead.

Just put your hand in the Microwave and cook for 5 minutes, to get a glimpse of the power of using microwaves over lasers. And the lasers dont have sharks attached so whats the point...
Extra crispy or original recipe?
(Stupid Idiot Warning: please do NOT do any of the said mentioned above)
maybe it can be used to drill a hole in Steve Ballmers head to let some hot air out and reality in...
That device is very similar to my 'Death Ray TM'
By heating a target to nearly 2,000 C, the microwaves soften it up enough for a small rod to be pushed through

This sounds like a nice invention for burglars. Now they no longer have to make noise when trying to break the window.
Next week on /.: invention of a burglar alarm that can detect microwaves.
This probably would have solved the cracking problem in Apples now defunct cube...

...the price of tinfoil hats has doubled overnight in response to the news. A foil hat manufacturer, when asked, was quoted as saying "Well, we had to double the price. People gotta protect themselves from those orbiting mind-control lasers, alien mind probes, and now they gotta worry about Israeli scientists drilling holes in their heads!"

I'm assuming the microwaves don't work any more after they use them to drill the whole?
Think "Return of the Pink Panther in the 21st Century..."
What else is a silent, dustless, precision glass cutter good for?

P.S. - This is a joke. Please do not feel compelled to point out that the thing probably fills up a whole lab and has all the portability of a pile of bricks.

Alumina is Al203, a very stable oxide of aluminum. Its properties are entirely different from aluminum and making a ceramic clear isn't that novel.
I could be wrong here, but wouldn't an ultraviolet laser be far more effective? Glass is not transparent to the UV spectrum so shouldn't it be able to "drill" right through it?
Unbreakable toys can be used to break other toys.

Weren't they doing this back in the 80's on a much bigger scale as a possible "star wars" weapon?
It's obvious the damn Israelis are merely developing this so that they can "drill" through innocent Palestinians' skulls. It is disgusting--absolutely horrific. This is one terrorist nation that must be stopped.
a conducting film or fine wire mesh in the wires should sort it
plus you are goign to probably need a big battery to get through my double glazing

Didn't someone recently make a homemade forge out of a common microwave? Seems these babies have got some uses it took us a decade (or two) to figure out! has it been a decade? bah!

It's just as well you don't design tanks. With a pinhole through the armor you could deliver anything from blast to nerve gas.

Since no man is truly complete without a portable power drill, I eagerly await a consumer version of this drill. ;)
i hope my dentist doesn't hear about this.
I wonder how it would work against a semi-perfect mirror? I've always wondered how a laser or something that would rely on waves would work against a reflective surface.. Can anyone give me a clue?

I'm sure the IDF will not hesitate to cook a few of their Arab friends.
This makes me wonder about security issues. Imagine if something powerful enough to direct these microwaves at glass from a distance. Lets also say the glass is bullet proof glass. Could that shatter the glass? Perhaps it doesn't destroy the glass but compromises its integrity to the point where teflon-coated bullets can penetrate it. Interesting....
With high voltage current you can melt holes in glass... Even a small TV induction coil will do.
Put the HV wires on either side, if it doesn't start arcing through it then increase the voltage... The problem is that the glass at the hole heats up and the expansion often breaks the rest of the sheet.
it doesn't work very well with good heat conductors or materials with very high melting points, but the researchers envision a wide variety of manufacturing applications, and possibly some medical uses as well
Right. I know human tissue doesn't conduct heat well, but does anybody know its melting point?
Any sufficiently simple magic can be passed off as mere advanced technology.
Sapphire's melting point, for instance, is too high. And steel conducts heat too well for a hot spot to develop.
Somehow that gave me a mental image of a woman and a man being attacked by Time with more down-to-earth method instead of using parapsychological powers. (I wonder if anyone recognizes the reference ;)
Everyone who makes generalizations should be shot.
In future news: You too can save microwaves from future extinction!

And don't forget the military applications. Israel needs new ways to kill off the Palestinians. Tanks give them bad press.

Forget the cost of the 500W laser. Have you priced a live shark lately?
Palestinian researchers have developed two new methods for suicide bombings.
I didn't have anything in it, and accidentally hit the cook button instead of the minute timer button. 20 Minutes later, POOF! The whole thing caught on fire. Turns out that the mixing belt failed, so it was all focused on the door. The engineer said, "Lucky you didn't loose the whole house! I've seen them burn straight through glass light bulbs...."

Think of the possibilities for carving stone without cracking it. This could make it a lot easier for sculptors.
Scientists restrict study to entire physical universe; creationist
The "magical" thing about 2.45 GHz is that it's in the middle of one of the ISM (Industrial, Scientific and Medical) bands designated by the FCC. Since there are no licensed radio services right around there and any un-licensed service has to accept any interference it gets (you can't complain to the FCC that your neighbor's microwave interferes with your 2.45 GHz portable phone), everyone's microwave oven operates at 2.45 GHz.

I think this would rock for building a CPU heat exchanger. With hundreds of small tiny water filled holes it would wisk the heat away nicely.

In other news the next Star Wars will reference upgraded combat technology.
It's clear Palestinians don't use their heads, otherwise a peaceful resolution would have been achieved decades ago.
It would be best to target the genitalia of the palestinian subrace, so they cannot make any more bombs.
That could be a factor, surely there would be some savings in energy usage if they were.
Cutting transparent glass with a laser has to be hella ineficient.
