Researchers at the University of Bedforshire have developed a new technique for powering electronic device(装置). The system, developed by Professor Ben Allen at the Centre for Wireless Research, uses radio(无线电) waves as power.
Believed to be a world first, the team claims it could eventually eliminate (or get rid of )the need for conventional batteries. The university has now filed a patent application to secure the only rights to the technique.
Professor Allen and his team have created a system to use medium wave frequencies to replace batteries in small everyday devices like clocks and remote controls.
The new technique uses the “waste” energy of radio waves and has been developed as part of the university’s research into “power harvesting”. Professor Allen said that as radio waves have energy―like light waves, sound waves or wind waves―then, in theory, these waves could be used to create power.
“The emerging(新兴的)area of power harvesting technology promises to reduce our reliance on conventional batteries,” he said. “It’s really exciting way of taking power from sources other than what we would normally think of.”
The team is now waiting for the results of the patent application to secure recognition of the technique. Professor Allen said that the team’s achievements had all been done in their “spare time”. “Our next stage is to try and raise some real funds so that we can take this work forward and make a working prototype(模型)and maybe partner up with the right people and take this to a full product in due course,” he said.
“Power harvesting has a really important part in our future, because, just in this country, we dispose of somewhere between 20,000 and 30,000 tonnes of batteries in landfill(垃圾填理)sites every single year-that is toxic chemicals going into the ground.”
He added that development of the product could also be “commercially beneficial”. “The market for this is several billion pounds. We’ve seen market predictions for 2020 which have these kinds of figures, so there’s a lot of commercial potential in this area,” he said.
Pro-Vice Chancellor at the University of Bedfordshire, Professor Carsten Maple, said, “This type of work is a reflection of the university’s growing reputation and experience in conducting innovative(创新的)research.”

请阅读以下中学生的信息,然后匹配各中学生和他或她要选修的课程:
Mike spent his childhood mostly in his father’s study, where he read novels by British and American writers. Next term he will become a senior student. He thinks it’s time that he read more of their works and learned to write about them.
Joseph is good at the language arts, and in his spare time he likes to write short stories. It is his wish that his stories would be printed in local newspapers. So he is thinking of taking a course to develop his writing skills such as wording and paragraph organization.
Anna takes an active part in social activities. She is trying to write reports for newspapers about what she sees and hears. But few of them are accepted because of poor organization of information. She feels the need to improve her writing and communication skills next term.
Jan traveled worldwide with his parents when he was very young. Under their influence, he becomes greatly interested in stories of travel and adventure. He hopes to write his own stories in the future. So next term, he will choose a course to study the best writing of this type.
Susan comes from China. As a junior back home, she wrote quite a lot of short stories, some of which were published in newspapers. Her parents hoped she read some classics by Asian and Western writers. She thinks it helpful in her writing. So she is going to take a course of this kind next term.
