I know for one that I am getting really tired of how people use cell phones everywhere they go. Bathrooms, cars, restaurants, movie theaters, cars, restaurants, cars, restaurants... I know that there is a move afoot to potentially ban the use of cell phones in cars (at least for texting), since this has been proven to be more distracting than driving under the influence. The technology in this article also gives people and businesses another potential option to cut down on this distracting behavior.
Qualifier, if you are a courteous cell phone user, do not take umbrage. However; if you are one of those cell phone users that chats away on the freeway in the left-hand lane and are going below the speed limit, oblivious to anyone or anything around you; or if you are like Kenny Tarmac [Bob and Tom reference] and people within fifty feet of you can hear your side of your cell phone conversation - then please take umbrage :o)
This is news a lot of cheapskates aren't going to like, especially the kind of cheapskates who routinely poach on other people's wireless connection. There's now a paint you can use that will block Wi-fi from going through walls and into the arms of another, unauthorized, computer user. The University of Tokyo has developed a paint that is allegedly able to block radio frequency in higher spectra, where Wi-Fi and other, higher-bandwidth communications take place. Most Wi-Fi technologies operate at 2.4GHz; the Tokyo pain can reportedly block frequencies all the way up to 100GHz. A 200GHz-blocking paint is also in the works, according to this report.
Grumpy Wi-Fi owners might be rejoicing (presuming this stuff ever gets to the market, and isn't $100 a gallon). Likewise theater owners, who will surely be interested in squelching that pesky cell-phone problem once and for all (the paint also blocks in the lower frequencies that cell phones use.)
