Scientists from the institut polytechnique Grenoble INP and the Centre Technique du Papier have developed a novel new product so gratuitous, it almost seems necessary: a silver-crystal coated wallpaper that can block neighbours from freeloading off your Wi-Fi network. The silver crystals are arranged in such a way that they are able to block certain wireless frequencies, not least of which is the same frequency as a WiFI router.
But, what about just setting up a password-protected network? I don’t know. You most certainly can — and should — do that. But if, for whatever reason, an open network is what you desire, this silver snowflake-speckled wall-covering will have your back. Unless you have windows. They’re still working on a clear coating with protective power equal to that of the paper.
Also, there will of course be somebody out there who will buy this, someone who both delights in a room covered floor-to-ceiling in metallic snowflakes and believes said remediation is superior to setting a password (which is free, mind you — this wallpaper, when it’s released in 2013, will cost about as much as mid-grade conventional wallpaper). Who is this person?
