Backpacks generating electricity while walking
Scientists from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass., have invented a backpack that makes electricity from energy produced while the wearer walks.
The frame is worn as a jacket at the back, and the pack moves up and down as the person walks. A mechanism with gears collects energy from this motion and transfers it to the electrical generator placed in the pack.
Backpacks can hold a lot of stuff, leaving your hands free to do other things at the same time. Your backpack can also power your MP3 player, charge your cell phone if the battery conks off and can also give you light in the dark to your way home.
The backpack could be useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. As the pack can make its own electricity, users don't need to carry those extra batteries.
With these power-generating backpacks we can do a lot of things like listening to music, playing games at the same time.
Let us wait and watch when these backpacks come out in the market.
