Nanotube Paint Blocks Cell Phones on Demand

Kozar_The_Malignant writes "Newsday is reporting on a new nanotube paint that is able to block cell phone signals on demand. The nanotubes are filled with copper, suspended in paint, and can be applied to the walls and ceiling of places such as concert halls, churches, and classrooms."

Um, no. Since it is a passive method, this is not and will not be regulated. You can acheive a similar effect by putting a layer of copper shielding in your wall.

The novelty here is that it can be enabled and disabled at will.

The new asbestos?

There may be some serious health risks [jnanobiotechnology.com] associated with nanotubes and other small particles. Hopefully the companies involved do thorough health risk assessments before putting it up everywhere.

The FCC can't kill this, as it doesn't transmit anything to anywhere, it's not even a powered device (persay). For example, if a builder decides to line the walls of his building with lead to achieve the same result, tough luck cell user. If an interior designer likes chromium (and they did in the '20s) and builds a lobby that is in essence a Faraday box, tough luck BlackBerry.

Personally, I like the idea of creating a domestic space where I'm not being bombarded by microwave energy, around the clock. Just because every idiot neighbour I have feels that they need a WiFi network, cordless phone, and what-have-you, doesn't mean that I should have to sleep in their energy pollution.

You mean these?

That's cool, but where do you get the tiny little paintbrushes?

Here. [acs.org]

Just to prove that science is stranger than fiction :)

(Mod this interesting, if you want)
