21．（6分） A rainy day can be a chance to recharge. While you relaxed on the sofa with a movie, the raindrops falling on your windows might one day provide the power for your TV. This is the idea behind an invention that harvests energy from water.The technology is based on the triboelectric (摩擦电的)effect. An engineer at the University of Hawaii, David Ma knew that it’s possible to generate electricity by rubbing two things together. So, he thought, “Why don’t we use water?”A drop of water sliding across a surface coated with two different materials would generate enough friction to create an electrical charge. By placing metal wires that the drop of water touched as it moved, it should be possible to harvest electricity, he reasoned.It worked. In fact, the researchers lit up 15 LED bulbs with a single moving water drop.This is not the first time that scientists have got electricity from water-generated friction( 摩 擦 ). Earlier experiments, though, harvested the charge produced in a surface by a sliding drop of water. There, the surface had acted as an electrode(电极). This is different. The energy of friction is being harvested from the water itself.“It turns out,” Ma says, “the charge in the water drop is way more than the charge produced in the other electrode.” In fact, his team’s model generated almost 100 times more power than previous experiments from a single drop of water.“The tech。
