Environmental issues cropped up in a number of stories this week, as we discovered a solar-film technology for keeping beer cold, a power company that generates energy from cow manure, and a new, ultradorky take on the electric car. Our weekly column, Shift, kicked off by picking the upcoming Nintendo Wii game console as a winner. Among the other stories that caught and held our ADD-afflicted gazes in the past five days:

Tuesday: 2second tent: pitched before it hits the ground
Wednesday: Ricoh announces dual-format HD player
Thursday: Embrio combines motorcycle, unicycle, balls
