Here's the strangest thing I've seen in a while, a U.S. based company announced last week that they have created a wireless blocking paint. Contrary to what I initially thought, the intended use is not to help those who claim wifi signals induce headaches, but rather as a means of containing the signal within a building.

A bit of digging reveals that wifi blocking paint is not a new idea. In fact security expert Bruce Schneier notes an Information Week article on similar technology way back in 2004. The company mentioned in that article is even still in business.

The chief problems with wifi-blocking paint appear to be, powerful antennas can generally still pull out a signal, mobile reception inside the building is most likely equally blocked and then there's whole problem with windows.

According to this press release from EM-SEC, the makers of this new wifi shielding paint:

The tests demonstrated that intellectual property can no longer be stolen through the airwaves while inside an EM-SEC-coated facility. The results showed that a one-time application of the EM-SEC Coating creates an “electromagnetic fortress” by preventing airborne hackers from intercepting signals.

To be honest I can't even tell if the press release is a hoax or not. I don't think it is but the outlandish claims do seem a bit much. Either way if you believe the above statement please contact Michael and I using the links to the right as we have some valuable antique bridge hardware you will absolutely love.

On a serious note, I wonder if putting a coat of this paint, say on the bedroom walls, would help those people who claim that wifi signals give them migraines and other health problems?
