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 waves as power.
Believed to be a world first, the team claims it could eventually get rid of the need for conventional batteries. The university has now applied for a patent(专利) 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---in theory, these waves could be used to create power.
“The new 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 pattern 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 leave somewhere between 20,000 and 30,000 tons of batteries in landfill(垃圾填埋)sites every single year-that is poisonous chemicals going into the ground.”
He added that development of the product could also be “commercially(商业) 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 carrying out creating research.”

Zoos divide opinion: there are those who think it is cruel to keep animals locked up while others believe zoos are essential for the survival of endangered species.
To argue that zoos imprison animals is to misunderstand what zoos are about. Without zoos many of the creatures we love and admire would no longer exist. Every single day, over one hundred animal species vanish. Scientists predict that as early as 2050 one quarter of the Earth’s species will become extinct.
Some animals are in danger because they are hunted. Alarmingly the population of tigers has already fallen by ninety-five percent. Other species are in danger because of a lack of food. For example, there are fewer than 1300 giant pandas left in the wild.
Zoos have special breeding programmes to help those animals at risk. These breeding programmes are proving extremely successful. As Irene Shapiro from Zoo and Wildlife Support says, “the Puerto Rican Parrot has grown in numbers from just thirteen to about eighty-five and the Golden Lion Tamarin Monkey, which has almost ceased to exist twenty years ago, has been reintroduced back into the wild.”
Unfortunately not everyone understands this important role zoos play. For example, Brian Featherstone from the Anti-Zoo Forum says, “I can’t believe we take animals from the wild and put them in cages for the entertainment of the public! We should view them on film or TV in their natural environment.”
However, this misses the point. A zoo does more than display animals to the public. It ensures their survival. Without zoos you would not be able to see many of these animals on TV or anywhere else!

Britain is very fortunate in its system of public lending-libraries. These libraries have a of some 115 million books. And about one-third of the population are of public libraries. This lending and reference library service is, with some limitation, free.
Public libraries not only lend books, music scores(乐谱) and records, but also supply special libraries to , among children, patients in hospital and prisoners, and they in many kinds of extra activities, reading, lectures, film shows, music circles and cooperation in adult education.
The greatest and most famous library in Britain is that of the British Museum, which over six million books. A copy of every book, magazine, newspaper, etc. in Great Britain, must be sent to the British Museum. The reading room of the Museum is famous for the of scholars and people who have studied in it. The British Museum Library is not, by the way, a library.
The second library in Britain is the Bodleian Library at Oxford. The National Library of Scotland, Cambridge University Library, and the National Library of Wales are also famous and may a copy of every new issued in Britain. There is also a National Library for the blind, over 300,000 books in a specially type.
