NaturalNano says its high-tech paint will block cell phone calls

rude cell phone peopleA 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 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.Not everyone is happy with the scheme though:“We oppose any kind of blocking technology,” said Joe Farren, spokesman for The Wireless Association, the leading cell phone trade group. “What about the young parents whose baby-sitter is trying to call them, or the brain surgeon who needs notification of emergency surgery? These calls need to get through.”So maybe the best solution is to declare a law that allows you to throw your shoe at the head of people taking non-emergency calls in certain areas.Link
