UPI is reporting on a new type of paint created using nano-technology that can block cell phone signals -- and it can be enabled or disabled, not just always block the signals:
"You could use this in a concert hall, allowing cell phones to work before the concert and during breaks, but shutting them down during the performance," said Michael Riedlinger, president of NaturalNano.
Not that I understand much of this new nano stuff, but these tubes are not the conventional carbon based nanotubes, these are made of something called halloysite (made of aluminum, silicon, hydrogen, and oxygen).
What I want to know now: if they can block cell signals, how long will it be until they can block (or for that matter amplify) WIFI signals?
You can read more about this company and what they are working on here.
