Shoes can produce electricity

走在路上，突然时尚的iPod播放器没电了，你该怎么办？别着急，一家日本公司发明了一款可以为电子产品充电的新鞋。一起来看看这款“马力强劲”的酷鞋吧！

We all know that walking is good for our health. But do you know walking can also produce electricity? A Japanese company says it has found a way to power the iPod music players just by walking.

The company is developing shoes that can produce electricity as people are walking. The shoes have a small generator (发电机) and water-filled soles (鞋底). When people are walking, the steps make the water move fast. Then the small generator changes the power into electric power. Now the shoes can produce enough electricity to run an iPod music player as long as the wearer keeps walking.

The company predicts the shoes will be able to produce enough electricity to run a mobile phone in the future. “You will be able to power your mobile phone or talk on it if you connect the phone to your shoes and just keep walking,” says the spokesman (发言人) of the company.

What will this kind of shoes be like? We are not sure. But one thing is sure — when we have such a pair of shoes, we will never worry about our mobile phones running out of power.
