Jerome Kelty of Boulder County, CO was so concerned about how much carbon dioxide was being released into the air simply by the charging of iPhones® and iPod Touches®, that he decided to build his own solar charger for them and a range of other devices with USB ports. He won a new 'green' Mac computer, and you win his DIY instructions for the solar charger!
The Rescue Reel is a safety device designed for use in skyscraper catastrophies. Escape through the window and rapel down the side of the building down to safety much quicker than you could ever do in the emergency exits.

Solar panels that track the sun currently involve the use of motors and electronic control systems to move them and convert the power to energy. But a team of engineering students at MIT, inspired by heliotropic plants that move in the direction of the sun all day (like a sunflower), have developed a new method of motivation for the photovoltaic cells to move. Their invention won first place in MIT's Making and Designing Materials Engineering Contest (MADMEC) -- a $100,000 prize!
