Slapping on a coat of silence Company says its high-tech paint will

block cell phone calls

The intrusion of cellular phone rings into theaters, schools and

nearly every other nook and cranny of modern life may soon hit a

wall.

Playing to the backlash against ubiquitous communication, a company

called NaturalNano is developing a special high-tech paint that

relies on the wizardry of nanotechnology to create a system that

locks out unwanted cell phone signals on demand.

The paint represents a dream to those who seek a distraction-free

movie or concert experience, and a nightmare to those who

compulsively monitor their BlackBerry phones.

It is also another breakthrough application of nanotechnology, the

emerging science of harnessing sub-microscopic organisms for everyday

uses, like stain-resistant pants and transparent sunblock. The

National Science Foundation has predicted that nanotechnology

eventually will be a trillion-dollar industry.

His firm has found a way to use nanotechnology to blend particles of

copper into paint that can be brushed onto walls and effectively

deflect radio signals.

The copper is inserted into nanotubes, which are ultra-tiny tubes

that occur naturally in halloysite clay mined in Utah. The nanotubes

are about 20,000 times thinner than a piece of paper, too small to be

seen with even a conventional microscope. At this size, which is near

the molecular scale, materials have different physical properties

than they normally do.

By filling these tubes with nano-particles of copper, the company can

create a medium to suspend the signal-blocking metal throughout a can

of paint without significantly changing the way the paint adheres to

a surface.

NaturalNano will combine this signal-blocking paint scheme with a

radio-filtering device that collects phone signals from outside a

shielded space, allowing certain transmissions to proceed while

blocking others.

Farren said that any scheme to selectively block calls is illegal.

But Crowley of AMBIT Corp., which designed the radio filtering

device for NaturalNano, said the system is legal. The nanotech-

augmented paint that blocks signals is a passive device, not an

illegal radio jammer, he said.

The radio filter would allow all emergency radio communications to

pass through the shield, Crowley said. With all other signals, like

cell phones, the filter would act like a spigot to block or allow

them to pass through—say, only during intermission.

" There'd be no limitation of public service radio access, " he said.

Bill , director of instructional support services for Sioux

Falls, S.D., schools said his district is interested in NaturalNano's

signal-blocking paint because administrators are worried about what

would happen in the event of an emergency in a school.

Even though they're illegal, jamming devices that emit radio signals

to prevent cell phones from working are widely available, said Tim

Kridel, a wireless industry analyst.

" You can find plenty of jammers on the Internet that are shipped from

other countries, " said Kridel. " But using them risks getting into

trouble with the Federal Communications Commission. "

Farren, the wireless industry spokesman, said that jamming doesn't

seem to be a major problem.

" But it's hard to detect, " he said. " Nothing shows up on your phone

that says 'Your signal's being jammed.' "

Based on phone inquiries and Web site visits, AMBIT's Crowley said

many people apparently want a legal way to control wireless bad

behavior.

Sounds very intersting. I am not surprized. I am not familiar with physics but

this may have promise. I need a demo.
