When I'm not blogging, I'm browsing. Here are sites and pages that I bookmarked on November 22nd: Wave Gliders Begin Historic Swim Across Pacific: Yesterday, four Wave Gliders (self propelled robots, each about the size of a dolphin) left San Francisco for a 60,000 kilometer journey. Built by Liquid Robotics, the robots will travel together to Hawaii, then split into pairs, one pair heading to Japan, the other to Australia.
