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．

Oceans cover three quarters of the earth’s surface．That would make wave power seem perfect for creating energy around the world．There are some drawbacks, however．

Jamie Taylor said that wave power still cost too much money．He said that its effects on animals in the sea were still unknown．Plus, wave power would get in the way of fishing and boat traffic．

With more research, however, “many of these problems might be overcome,” Taylor said．“Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world．Finding more energy sources is very important, for traditional sources of energy like oil and gas may run out some day．”

In the future, when you turn on a light switch, an ocean wave could be providing the electricity!

　　 About 1966 or so, a NASA (美国航空航天局) team doing work for the Apollo moon mission took the astronauts near Tuba City．There the landscape of the Navajo Reservation (保留地) looks very much like the lunar surface．Among all the trucks and large vehicles were two large figures that were dressed in full lunar space suits．

Nearby a Navajo shepherd (牧羊人) and his son were watching the strange creatures walk about, occasionally being watched over by other NASA workers．The two Navajo people were noticed and approached by the NASA people．Since the shepherd and his son did not know English, they asked the NASA people who the strange creatures were．The NASA people told them that they were just men that were getting ready to go to the moon．The shepherd became very excited and asked if he could send a message to the moon with the astronauts．

The NASA officials thought this was a great idea so they provided a tape recorder．After the man gave them his message, they asked his son to translate．His son would not．

Later, they tried a few more people on the reservation to translate and every person they asked would chuckle (偷偷地笑) and then refuse to translate．Finally, with cash in hand someone translated the message,

“Watch out for these guys, they have come to take your land!”
