Electricity, like clean water, is a resource that’s often taken for granted. But last summer, when blackouts struck much of the northeastern US, Ontario and Rome, consumers on two continents were given a painful reminder of just how easily broken electricity supplies can be. The massive disorder stranded (使陷入困境)commuters, stopped freezers, shut down businesses and refocused attention on where most of the planet’s power comes from:oil-and-gas-fired generators and nuclear plants, These sources not only pollute the environment but also make many consumers feel unacceptable health risks.
Companies are trying to offer an alternative, clean energy from renewable resources that’s plentiful and portable. Lifton’s Medis Technologies, as well as companies like Hydrogenics and Nanosys, is tapping into fuel cells and dolor panels to give people power whenever and wherever they want it, free from dependence on local grids(电网).
The search for alternative energy is nothing new, but the current trend of innovators is focusing on the goal of making clean and sustainable power a mainstream commodity. For example, the fuel cell, which produces electricity from the chemical reaction between oxygen and hydrogen, has been around for about 150 years, though its commercial development did not begin until the 1960s and then only as part of NASA spacecraft. Today this technology is coming down to Earth in places like Tokyo; in nine European cities, from Stockholm to Porto, each operating three hydrogen-fuel-cell buses; and in Iceland, which is trying to create the first fuel free hydrogen economy by 2030.
When hydrogen and oxygen molecules(分子)combine, the reaction produces heat and water. Fuel cells use this reaction to generate electricity. With the cell phone and gadget(小机件)market in mind, Medis has developed a fuel cell with cheap components that produces little heat and effortlessly reduces waste water without turning to energy consuming pumps.

Ron Meyer is the president and COO(首席运营官) of Universal Studios.As one of the most successful business leaders in Hollywood, he heads up Universal Pictures and Universal Parks & Resorts.He's the guy who oversees the production of Multimillion-dollar extravaganzas(作品) like King Kong and Cinderella Man.
Meyer’s story sounds like the plot of one of his motion pictures.He grew up in a modest home where there was little income.It was a big deal to go to a restaurant.At 15, he quit high school and spent his time hanging out with the neighborhood toughs(流氓).He was then a kid quick with his fists who seemed to get into fights somewhat regularly.At one point, he was separated from others with an infectious disease, having no TV and nothing to do.His mother sent him two books.One was The Amboy Dukes, a novel about kids in street gangs.The other was The Flesh Peddlers, about a guy in the talent agency(星探公司)who lived a successful life.“I realized,” he says, “that I was no longer that silly kid I had been, and I wanted to change my life.”
Meyer took any job he could get.He worked as a busboy and short-order cook.He cleaned offices and sold shoes.That attitude made an impression on people.One day he received a call from Paul Kohner, a successful agent who represented stars like John Huston, Charles Bronson and Lana Turner.Their messenger and driver had quit, and they knew Ron was willing to take whatever job they offered. He started the job the next day.
Meyer was lucky to work with a good boss―and he had the brains to make the most of that experience.In nearly six years of driving for Kohner, Meyer became his right-hand man and learned a lot.By the 1970s, Meyer had built many relationships in the business.In 1975, the fate presented an opportunity and he started his own operation Creative Artists Agency, which became a huge success, representing Hollywood legends like Barbra Streisand, Tom Hanks and Tom Cruise.
Twenty years later, Meyer was appointed to run Universal Studios, a position far beyond his youthful dream.But once he saw success was possible, he was driven to achieve it.Today, colleagues regularly owe his success―and theirs―to his humility and perseverance.It’s a level of success that takes determination, personality and intelligence, whether it comes from a college education or from the street.

I had an experience some years ago, which taught me something about the ways in which people make a bad situation worse by blaming themselves. One January, I had to hold two funerals on successive days for two elderly women in my community. Both had died “ full of years”, as the Bible would say. Their homes happened to be near each other, so I paid condolence(吊唁) calls on the two families on the same afternoon.
At the first home, the son of the deceased(已故的)woman said to me, “ If only I had sent my mother to Florida and gotten her out of this cold and snow, she would be alive today. It’s my fault that she died.” At the second home, the son of the other deceased woman said, “ If only I hadn’t insisted on my mother’s going to Florida, she would be alive today.That long airplane ride, the sudden change of climate, was more than she could take. It’s my fault that she’s dead.”
You see that any time there is a death, the survivors will feel guilty. Because the course of action they took turned out bad, they believe that the opposite course—keeping Mother at home, putting off the operation—would have turned out better. After all, how could it have turned out any worse?
There seem to be two elements involved in our willingness to feel guilty. The first is our pressing need to believe that the world makes sense, that there is a cause for every effect and a reason for everything that happens that leads us to find patterns and connections both where they really exist and where they exist only in our minds.
The second element is the view that we are the cause of what happens , especially the bad things that happen. It seems to be a short step from believing that every event has a cause to believe that every disaster is our fault. The roots of this feeling may lie in our childhood.
A baby comes to think that the world exists to meet his needs, and that he makes everything happen in it. He wakes up in the morning and summons the rest of the world to its tasks. He cries, and someone comes to attend to him. When he is hungry, people feed him , and when he is wet, people change him. Very often, we do not completely outgrow that childish view that our wishes cause things to happen.

Due to climate change, Arctic ice is breaking up earlier in the spring, and its area is decreasing. This is creating problems for polar bears that make their homes off northern Alaska and in Hudson Bay.
Polar bears off Alaska normally hunt and raise their young on ice sheets that float on the ocean. But as the ice has melted, the polar bears have been forced to spend more time on land. There, they have begun to frequent beaches, feeding on the remains of whales caught by native hunters. For polar bears, this food is less nutritious than seals that they normally catch on ice sheets. The shrinking(减少) ice has also forced more polar bears into the ocean. In the past, they only had to swim short distances between ice sheets. But as the ice has shrunk, polar bears have been forced to swim longer and longer distances in the open ocean. This poses a severe danger during rough weather, and an increasing number of drowned polar bears have been observed.
In Hudson Bay, the ice breaks up three weeks earlier in the spring now than it did 20 years ago. Polar bears on Hudson Bay fast(绝食) during the summer, waiting for ice to form in the fall to hunt. Every year, the summer gets longer, and the bears get skinnier. Over the past 25 years, the average weight of the female bears has dropped 68 kg. This loss affects their ability to reproduce, and already the number of births has dropped 15 percent. Unless the bears can learn to survive these climate changes, these giants of the ice may one day disappear.
