The University of Tokyo has developed a paint that will absorb electromagnetic waves used in Wi-Fi. Meaning, you can finally stop your neighbors from leeching off your wi-fi.

The paint is made of aluminum-iron oxide that vibrates around wi-fi frequencies. Only till recently did “wave absorbing materials” been able to block frequencies above 50Ghz (wi-fi uses 100Ghz). Thanks to Japan; however, the paint can now absorb to 4 times as much.

As awesome as this sounds, I hope they don’t use it at Starbucks.

Ditto, I hope they don’t use this stuff at Starbucks and other coffee shops… I never got away with leeching WiFi off my neighbors in college, though. Everybody had their WiFi on lock down and also had threatening network names (us too, but we had a friendly network name).


or, you can just turn on WEP encryption… just a thought
