Flat Holm, a small island in Britain's Bristol Channel, has no permanent residents and minimal infrastructure（设施）. The pretty land mass is now, however, becoming increasingly popular with tourists wishing to explore the rural landscape and view the island's seabird colonies.

    Though this is welcome news, meeting the island's growing energy needs without ruining its environment poses a challenge. Flat Holm team leader Natalie Taylor says, “As we promote the island more and we get more visitors here, there's going to be a lot more demand for electricity so it's really important that we've got a really high functioning system that can provide for those people. From an environmental point of view, we want to reduce the use of diesel（柴油）generators so that we can have as small ecological footprints as possible.”

    While the Cardiff Council, which oversees the island, considered traditional solar and hydroelectricity, it was reluctant to carry out either, due to their high cost and permanent nature. According to energy and sustainability manager Gareth Harcombe, the officials were seeking a portable option that could be moved if the site was needed for another purpose.

    Fortunately, the UK-based company Renovagen had the perfect solution. A small panel can provide 11kW of power within two minutes. A more extensive version, unrolled from a shipping container, can yield 300kW of electricity in less than an hour.

    The solar panel “carpets”, laid on the island in early October, are being used to provide electricity to its sole pub and lighthouse. The Cardiff Council also plans to use them to charge two Nissan e-NV200 electric vehicles in the future.

    In addition to providing power to remote islands like Flat Holm, Hingley hopes the Rapid Roll technology will be useful in areas affected by natural disasters. A good example is Puerto Rico, where most residents have been without electricity since Hurricane Maria destroyed the power lines in late September.

    US people are overweight, eat lots of fast food and fill their homes with pets. At least that's what 21 European teenagers think.

    The students, 18 from Germany and 3 from France, are exchange students. They are studying in the US for a year. After a few days in the US, they said what they thought about the country.

    Most talked about the amount of fast food US people eat. It's not that the students don't eat fast food. They just don't eat as much.

    Laetitia Villeneuve from France said she eats fast food, usually McDonald's, only once or twice a year.

    "I like it," said Nora Koeberle from Germany. "But I couldn't eat it every day. I'd get fat. "

    Students are surprised at how big US people seem.

    "There are fat people in Germany," said Antonia Greimel from Germany. "But not as many as there are here."

    They also spoke about the animals. Silvana Wolfram from Germany said she had heard about how people had lots of pets in the US.

    Other ways of US high schools interested the students.

    For example, Koeberle said she wouldn't be able to play an instrument or sports as part of her classes in Germany. She can in the US.

    But the best thing about US high schools is something the European kids can't get back home. "I do wish we had parties," Koeberle said.

    As anyone who freelances (做自由职业) knows, there are lots of advantages of working at home alone. But there are drawbacks too, like the potential loneliness. No wonder co-working spaces are becoming so popular, they permit self-employed individuals to feel like they are part of all office environment, while making them get some work done too. But renting a co-working space does cost money.

    Now a Swedish project is aiming to change that by turning people's under-used homes into temporary co-working spaces, available to freelancers for free. Hoffice was started by freelancers Christofer Gradin Franzen and Johline Zandra about a year ago in Stockholm when they invited a few people into their home office to work together. It was a great success, and the project has since spread to a number of cities in Europe, North and South America, Australia, India and Japan. Anyone can sign up and offer their home space as a free co-working space, or go find a Hoffice near them.

    On a Hoffice day, everyone arrives and starts work at a certain hour. After 45 minutes，everyone gets up to take a break, stretch, do qigong or yoga for 10 to 15 minutes. Afterwards， people can gather around again, and re-state their intentions and goals for the rest of the work day, as a way to motivate each other. Meals can be eaten together at a certain hour, potluck-style (家常饭) or by bringing their own lunch.

    This process creates an encouraging and supportive work environment. As some freelancers describe, "By working at Hoffice, we give ourselves and each other the gift to spend our days in a social working environment, where we are extremely productive without ignoring our other human needs. We also make sure to give ourselves and each other what we need to feel calm, happy, inspired and creative during the working day."

    So Hoffice is not just about sharing space; it's also about a free exchange of ideas. And perhaps the best thing is that Hoffices are free to use.

    As the international demand for narrative(叙事的) film/TV content continues to increase with popular streaming services like Netflix and others the two questions then come: will the coming generations receive most of their entertainment through visual means rather than through the written word and will such an increase of narrative film/ TV reduce the importance of reading?

    Growing examples of this trend include the diminishment(减少) of fiction in the common core (核心的)curriculum, the ever－rising culture of computer games, the wave of streaming services of wide international reach, and movies filled with special effects made for children and teenagers. Nor must we ignore the economic dangers that lie ahead for the written word. The narrative film industry is a moneymaker that dwarfs(使相形见绌) the publishing industry.

    The other underlying question, of course, is "does it really matter if the written word bows to the world of film/TV?" From my point of view, any diminishment of fiction delivered by words is a loss for mankind.

    There is no greater human feature than the imagination. It lies at the very soul of the human species. It is the brain's most powerful engine. It is the essential muscle of life and like all muscles it must be exercised and strengthened.

    Writing and reading are the principal tools that inspire, create and empower our imagination. Anything that diminishes that power is the enemy of mankind.

    It should be known that I am not opposed to new media and technological advances. Instead, I have always felt it necessary to adapt to advancing technology. In fact, a number of my novels are in various stages of development for film, TV, and live stage productions. My hope is that the written word will only stand to be complemented(补充)by its visual counterparts(对应物), not pushed to the edge of extinction.

    Of course, there are those who will present arguments for the superiority of the moving image over the written word. Each has its place. My argument is for finding the right balance between it and the moving image.

    Still seeking a destination for your weekend break? There are some places which are probably a mere walk away from your college.

    King's Art Centre

    A day at the Centre could mean a visit to an exhibition of the work of one of the most interesting contemporary artists on show anywhere. This weekend sees the opening of an exhibition of four local artists.

    You could attend a class teaching you how to learn from the masters' or get more creative with paint—free of charge.

    The Centre also runs two life drawing classes for which there is a small fee.

    The Botanic Garden

    The Garden has over 8,000 plant species；it holds the research and teaching collection of living plants for Cambridge University.

    The multibranched Torch Aloe here is impressive. The African plant produces red flowers above bluegreen leaves, and is not one to miss.

    Get to the display house to see Dionaea muscipula a plant more commonly known as the Venus Flytrap that feeds on insects and other small animals.

    The Garden is also a place for wildlife enthusiasts. Look for grass snakes in the lake. A snake called ‘Hissing Sid' is regularly seen lying in the heat of the warm sun.

    Byron's Pool

    Many stories surround Lord Byron's time as a student of Cambridge University.  Arriving in 1805, he wrote a letter complaining that it was a place of "mess and drunkenness". However, it seems as though Byron did manage to pass the time pleasantly enough. I'm not just talking about the pet bear he kept in his rooms. He spent a great deal of time walking in the village.

    It is also said that on occasion Byron swam naked by moonlight in the lake, which is now known as Byron's Pool. A couple of miles past Grantchester in the south Cambridgeshire countryside, the pool is surrounded by beautiful circular paths around the fields. The cries of invisible birds make the trip a lovely experience and on the way home you can drop into the village for afternoon tea. If you don't trust me, then perhaps you'll take it from Virginia Woolf—over a century after Byron, she reportedly took a trip to swim in the same pool.
