If you've ever wanted to live in a fancy Faraday cage, here's your chance. An $8.6 million condo for sale in San Francisco has walls thickly covered in semiconductive graphite paint, floors connected to the walls with wire tape, and walls connected to the ceilings with wire strips. Oh, and its windows are coated with EMF-blocking polymer. All these are courtesy of the people who snapped up the condo, which was then a fixer-upper, back in 2007. They basically wrapped the whole place in aluminum foil-like substance in order to keep out any EMF radiation emitted by phones, GPS devices, WiFi routers and other electronics.
