Scientists at the university of Tokyo have developed a new paint that is designed to block higher frequency elctromagnetic waves, like those found in WiFi. This isnt exactly new technology, we have been blocking cell phones for a while, but the ability to block the higher frequency waves from free loaders who might want to use your wireless connection.

This stuff should run around $50 a gallon, but can you really put a price on privacy.
