Don’t know if any of you picked this up from el reg. A US company called Force Field Wireless has created a paint containing “laced with copper and aluminum fibers that form an electromagnetic shield, blocking most radio waves and protecting wireless networks”. It does seem like a revolutionary idea but I have the following questions?
- Are the radio waves being blocked or deflected? Not trying to be stupid here but the metallic elements in the paint are more than likely reflecting all electromagnetic signals back into the house? This may not be a great idea as depending on the amount of electromagnetic devices your operate in your house you’ll increase your exposure to background non-ionising EMR
- Ignoring health concerns, which aren’t conclusive anyway, will it affect your ability to get a mobile phone signal in your house?
- What about windows? (and I don’t mean the OS)
