Al Gore would have been proud of us this week. Not only did we profile three (count 'em!) solar-powered gadgets — a "stylish" visor, a panel for your house, and a totally wireless surveillance camera — but we also encouraged folks to find more environmentally friendly ways of getting around, from personal blimps to futuristic electric cars. Meanwhile, we took a hard look at waking up via a sleep-analyzing watch, and fired up the crystal ball to see what the future holds for Apple's new Time Machine data-backup application, coming to Macs everywhere soon. Other buzz generators this week:

Monday: Apple unveils Mac Pro tower, does not cure cancer
Tuesday: Sony unveils Mylo wireless media player
Wednesday: Virtual Girlfriend/Boyfriend keeps real girlfriends/boyfriends at a distance
Thursday: Ballbot rolls around and balances with ease
Friday: Flip remote brings phone design to the living room
