A New York company called NaturalNano is claiming that it's developed a paint that can block cellphone and WiFi signals - yet be toggled off to allow selective, chargeable access.
If the paint works as promised, then public venues, such as cinemas, libraries and theatres (as well as schools) could become HELLO!-free zones, without the usual cost involved of embedding wiring into walls to shield radio-frequency signals. But, it also means that companies could charge WiFi users to access their own networks and networks that they themselves don't provide.
According to Michael Riedlinger, president of NaturalNano,
We're not sure about the chargeable side of things but do fully sympathise with the idea of cellphone-free public venues and schools. What we were wondering, though, is if there's any chance that nanotechnology - or technology of any other sort - might help with a related but quite different problem, the LACK of cellphone reception.
What we'd like is a paint that can amplify cellphone signals. That really would be a breakthrough - not least because it would mean we'd at last be able to use cellphones in our east London offices!
