With its focus on reducing waste and utilizing environmentally friendly materials, Nike's new Air Jordan XX3 could well be the very first "green" shoe to drop in the team sports footwear market. Rather than using environmentally toxic adhesives and glues, the shoe is constructed with a pioneering system of interlocking panels - a design that required brand new machines for production.

Indispensable for the student or professional whose computer must always be charged, this solidly designed and comfortable backpack sports three sturdy, waterproof solar panels that provide power via a custom battery pack.
