A pair of shorts that charges your phone when you walk.

Scientists have invented a pair of shorts which store energy to charge wearer's phone battery while they are on their move. An average person wearing the power shorts and going for a stroll can generate enough energy to charge a battery for four hours. The power shorts are made using a fabric which changes walking to electrical power. Gaps in the clothes are squashed together during normal movement and energy created is then converted into juice for your mobile. In addition to the shorts the scientists have also come up with a sleeping bag to charge your smartphones when you are asleep. The mechanism to charge in this is similar to the power shorts but instead of movement turns body heat into battery for a mobile. And after a person sleeps for eight hours he stores enough energy to power their mobiles for the rest of the day.
