In summer, millions of people will head for the beach.And while the ocean can be a great place to swim and play, it may also be useful in another way.Some scientists think that waves could help make electricity.
“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave? Or have you jumped in the water and felt the energy as waves crashed over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland.“There is certainly a lot of energy in waves.”
Scientists are working on using that energy to make electricity.Most waves are created when winds blow across the ocean.“The winds start out by making little ripples (波纹) in the water, but if they keep on blowing , those ripples get bigger and bigger and turn into waves, ”Taylor said.“Waves are one of nature’s ways of picking up energy and then sending it off on a journey.”
When waves come towards the shore, people can set up dams or other barricades to block the water and send it through a large wheel called a turbine (涡轮) .The turbine can then power an electrical generator (发电机) .
The United States and a few other countries have started doing research on wave energy , and it is already being used in Scotland.
The resource is huge.We will never run out of wave power, besides, wave energy does not create the same pollution as other energy sources, such as oil and coal.
