Vint Cerf

Celebrity EntourageVint Cerf, who now works for Google, attained rock-star status in tech circles by helping to design the Internet itself. He travels the world encouraging people to adopt new Net plumbing called IPv6, but he's doing his part on the home front as well.

His favorite technology is a network of sensors to keep his wine cool. "My wine cellar is monitored by an Arch Rock sensor network (IPv6, 6lowpan, mesh) and sends a text message if the temp is over 60 degrees Fahrenheit," Cerf said. He's got more ambitions, too. He wants to set up a remote actuator to reset the cooling system from afar when necessary, and he'd like to tag his wine bottles with RFID (radio-frequency identification) chips for electronic scanning.
