Keep your portable jammers at home. Here is a unique paint which will automatically turn your cell phone off when you enter the room. NaturalNano, Inc is been developing a special paint which would allow to block specific radio frequencies. So how does this work? Here’s the solution:
1. Halloysite nanotubes coated or loaded with copper may be used in paint applied to walls to passively block specific radio frequency ranges.
2. Two-way radio-frequency transmissions from cell phones, WiFi, and other electronic devices may be blocked.
3. Using a complementary technology licensed from AMBIT Corporation, building managers may selectively override the blocking to allow the use of two-way devices in a room or building. An indoor antenna picks up cell-phone or other signals and sends them to an external antenna through an electronic filter. A facility manager can enable transmissions at specific frequencies or for specific uses. For example, police, fire and other emergency communication calls could go through.
4. An outdoor antenna transmits and receives the cell-phone (or other) signals. The antenna may also improve reception for buildings in marginal coverage areas.

Cool!!!
thank god peace at Theaters.
How about a true title?
“Paint will block your cell phone”
or something not trying to claim it will…turn it off.
haaha pain a friends house with this paint
it blocks not turns off
Realy cool one.
People will still talk during a movie, how about cattleprods build into the seats.
So then the phones automatically turn up their power to try and get a connection, and everyone in the room gets their brain fried.
Plus the people who would have turned their phone off get into the habit of never bothering
Do you really want your neurosurgeon to be prevented from getting a page when you need brain surgery? Or your transplant surgeon? How about if you wre a transplant patient, would you not want to get the phone call that could save your life? Or parents to be prevented from getting calls from their babysitters when something goes wrong? One of the greatest advantages that mobile phones have given people is confidence that they go places and not have to worry about being out of touch.
I hate people getting phone calls in movie theatres, but the real problem is the ringing and rarely rude people who actually answer the call in the movie theatre. (yes, I’ve witnessed people have entire conversations during the movie). The only time I think a solution like this works if for top secret areas where you don’t want people to be able to make calls. Casinos is another for legal reasons. Either way, there should be a law that requires telling people that their cell phones won’t work in a specified area.
I don’t think this is a good idea because it completely disables the entire cell phone signal. If there were a way to simply disallow voice services I would welcome it. I do not have any problem with people text messaging in the movies as long as they keep their phones off.
If this does become widely used I think it would be a good thing for a law to require places to post signs about when and where signals would be nonexistent.
If you are a neurosurgeon and on call, then perhaps you should not go to the movies. Netflix a DVD and watch it at home. Or, go to the movies, but every half an hour, go to the theatre door and check to see if someone’s temporal lobe needs patching up.
I get tired of people using the lame excuse that doctors and others need to be available while they’re watching movies. If they are on call, they know they need to be somewhere where they can be easily available. In other words, they shouldn’t be at the movies! And, what did we do before cell phones? Things worked just fine. These types of excuses seem to me to be nothing more than people trying to act more important than they really are.
This type of Faraday cage seems like a wonderful thing. It would also work great in auditoriums and theaters which use wireless audio systems (microphones, speakers, stage crew intercoms, etc.). These systems receive interference from cell phones that are only silenced, because the radio signals are still being received and transmitted by silenced phones.
To Michael:
Should there be a law on all buildings, and in all places that naturally block cell phones because of the heavy concrete? Or places where there is no reception? It’s not as if the paint is going to pop up in every building out of nowhere – you’ll learn from experience and make decisions based upon it.
I agree, phones going off in the cinema is really enoying.
BUT what about doctors who are on call?
This techonolgy would block the signal to their pager/cell phone. Meaning they can’t be reached. If anyone where to die as a direct result of a doctor not getting there page, because of the paint in their local cinema, you can bet the cinema would get sued, big time.
After that the paint will be stripped off every cinema in the country, in fear of being sued for there choice of decore…..
While this is a “cool” technology, I feel it should not be needed. People should have the responsibility and courtesy to turn their phones to silent before the film begins.
I believe that no cell phone should be used in public if any other person is within earshot, period. There should be a sign at all checkout lines and in all restaurants notifying customers that all who use their cell phones will be charged an additional $10.00 for that offensive behavior. Phone calls should be made or taken in private and all who do otherwise should be chastised and identified as the bums they are. I would make exceptions for emergencies but,
professionals ‘on call’ should not attend public events.
Albert:
Wow that view seems a little extreme. You think that phone calls should be taken in complete privacy? This is a problem with normal landline phones as well, maybe we can charge people who use their home phones within earshot of people as well. I don’t have any problem with someone talking on the phone in a checkout line, although it is a little rude to completely ignore the cashier once it is their turn. I guess I like the world where people can make their own decisions instead of having extreme totalitarian rules that exploit every right of free speech. I understand the point of having people keep quiet in places like a movie theater or a church, but not in public places such as a grocery store. Also, I think it is stupid to say that people who are on call cannot attend public events. Many professionals are on call at all hours, do you expect them to just sit at home and watch television? This is almost too hard to believe are you a member of CRAP or something?
