[1] Scientists in the United States are working on a technology that uses human energy to power devices like cell phones, laptop computers, and GPS systems.

[2] Tom Krupenkin, who teaches electrical engineering at the University of Wisconsin and his team want to reduce dependence on costly and polluting batteries. Instead of using batteries for power, they have turned to human beings and have placed a device in a shoe that collects and stores energy from human motion and turns it into electricity. One part of this device is an energy harvester. It has two small containers filled with thousands of very small drops of liquid. These droplets get pushed back and forth as a person walks and can directly convert it into electric power. Output of this energy is stored in a regular rechargeable tiny battery of the style that we have in cell phones.

[3] The team has also developed a system to permit use of the stored energy by common mobile devices. It does not require connections with wires, and can be used to create a wireless signal. A cell phone that uses the wireless “hotspot” from the shoe would use much less power if   __________   a wireless telephone network. The devices are about the size of a credit card. Professor Krupenkin says the system is always powered. So unlike a traditional battery, this energy harvester never needs to be recharged.

[4] The professor says he does not expect this invention to replace traditional batteries. But it will help reduce dependence on them. He says there are a huge number of possible uses for this technology. Professor Krupenkin thinks the technology would be useful for people in rural areas where there is no electrical power.

[5] He stresses that it makes a lot of sense for people who depend on devices like mobile phones and laptop computers. And he says the technology could be used by soldiers who must carry battery–powered electronic devices into difficult territory(地区).

[1]One Friday night in May 2010, Oliver and Ione Kleven heard angry shouts coming from their front lawn(草坪). Ione, 65, stepped onto the porch（门廊） and saw two men in dark clothes struggling with something on the ground—right where she and her grandson had planted a flower bed the weekend before.

[2] “Go fight somewhere else!” she shouted, worried her plants would get damaged. At the sound of her voice, the face of a boy appeared from beneath the two men. He looked 14. “They’re trying to kill me!” the boy screamed. Ione ran toward them and, without hesitation, caught the boy’s arm, pulling him out.

[3] “Leave him alone!” she shouted. When the men stood up, Ione saw what looked like a sharp object in one man’s hand. When she turned back toward the boy, he was moaning（呻吟） in pain and holding his stomach. The attackers began to move in on the boy again when Ione’s husband shouted: “Get lost!” The two men walked quickly and quietly across the street and drove off in a dark car.

[4]“I have to get to the hospital!” the boy cried. He lifted his shirt, and Ione could see a bloody wound on his stomach. Oliver hugged the trembling(发抖的) boy while Ione caught her cell phone and car keys inside the house. She handed the phone to Oliver. “Call 911,” she told him. “I’m going after them.” Ione took off but was unable to find the car.

[5]The Klevens then learned what had happened . Earlier that night, as the boy waited for his parents to pick him up from the high school across the street from the Klevens’ house, two men approached and demanded his wallet. When he refused, one of the men hit him in the face. The boy ran across the street. The men caught up with him, and one hurt him in the back and stomach with a sharp knife. That’s when Ione stepped in.
