Soon backpackers and/or outdoor geeks will be carrying all of their electronic accessories into the wilderness, or at least that is how one inventor may have wanted it.

It simple. Someone has applied the same kinetic watch concept to a back pack that creates and stores energy. With every up and down movement the backpack creates a charge. The charging backpack was specifically designed to move around such that it can create the necessary motion to harness a charge.

The backpack is no small fry, though. Weighing in at 85 pounds, you will not only have electricity burning in your bag, but a workout to boot. The pack can produce as much as 7 watts of electricity, apparently enough to power a cell phone, MP3 player, GPS, night vision goggles, and a PDA.

The inventors, Lawrence Rome and colleagues at the University of Pennsylvania, theorize that the cost for generating this charge is equivalent to one additional snack. I have a hard time buying this considering the packs very weight, but who cares, its a cool invention that will hopefully slim down once, and if it hits the consumer market.

Grew up back East, got sick of the cold and headed West. Since I was small I have been pushing buttons - both electronic and human. With an insatiable need for tech I thought "why not start a blog focusing on technology, and use my dislikes and likes to post on gadgets."
