According to Andrew, it never would have happened if he had not had a flat tire on Highway 10 last night at about 7:30. He was on his way to attend a three-day sales meeting when he had the flat. tyre. Unfortunately, he did not have a spare, so he pushed the car off the road, locked it up, and managed to thumb a ride back to Pine Grove. It was after eleven o'clock when he finally got home, and it was then that his real problems started.
When Andrew left home at about 5:30, he had told his wife not to expect him back until Thursday or Friday. Knowing that his wife was nervous about staying in the house alone at night, Andrew took the precaution of checking all the windows in the house to be sure they were locked, so that he could report to his wife that the house was secure. He convinced his wife that the house was burglar-proof, and that she would be perfectly safe, providing she bolted （闩上）the front door as soon as he drove away.
Andrew's only thought as he made his way in the dark to his front door was how surprised his wife was going to be to see him, since he was not supposed to be back until Thursday or Friday. He had forgotten about the bolt on the front door. When he turned his key in the lock and the door wouldn't budge, he remembered the bolt. And he remembered that he had carefully locked all of the windows.
Although Andrew didn't know it at the time, a next-door neighbor had seen him approaching the house and had watched him go up the steps to the front door. In the dark, it was impossible for the neighbor to recognize Andrew, and, besides, the neighbor knew that Andrew had gone out-of-town for a three-day meeting. As a matter of fact, Andrew had asked the neighbor to keep an eye on the house while he was gone.
Finding that he couldn't get in, Andrew began pounding（砰砰地敲） on the front door to get his wife to open the door. According to Andrew, however, his wife is a very sound sleeper, and he knew it was going to be hard to wake her up. In the meantime, because of all the noise he had been making, the neighbor was convinced that somebody was trying to break into the house; so she called the police.
When we talked to Andrew at the country jail this morning, he said that he still didn't understand how the police managed to circle the house without his seeing them. He stated that he had decided the only way to get in was to break one of the dining room windows, and that he was about, to hurl his briefcase into the window to break it when two of the officers grabbed him from behind.
Andrew could not make the officers believe that he lived there; so they took him off to jail. Apparently, he did succeed in convincing them that they ought to wake up the woman in the house to check his story. But there was no answer when they knocked at the door. He tried to explain to them that his wife was a very sound sleeper, but they concluded there was nobody in the house.

More than 1.5 billion people around the world live without electricity. Finding better ways to bring light to the poor is the goal of researchers like Professor Irvine. In the late 1990s, he was working in Nepal when his return flight was canceled. A delay gave him time to take a fourteen-day hiking trip in the Himalayas.
One day he looked in the window of a school and noticed how dark it was. This is a common problem for millions of children around the world. Many families use kerosene oil (煤油) lamps. There are many problems with these lamps. They produce only a small amount of light. They are dangerous to breathe. And they are a big fire danger, causing many injuries and deaths each year. Kerosene costs less than other forms of lighting, but it is still costly in poor countries. Professor Irvine says many people spend over 100 dollars a year on the fuel.
When he returned to Canada, he began researching ways to provide safe and clean lighting. He began experimenting with light-emitting diodes (发光二极管), LEDs, at his lab. As a professor of renewable energy, he already knew about the technology. Light-emitting diodes are small glass lamps that use much less electricity than traditional bulbs (灯泡) and last much longer. He used a one-watt bright white LED made in Japan. He found it on the Internet and connected it to a bicycle-powered generator (发电机). He remembers thinking it was so bright that a child could read by the light of a single diode.
In 2000, after much research and many experiments, he returned to Nepal to put the systems into homes. Now the homes of 25,000 people in 51 countries have been equipped with it. “The one-time cost of our system which basically lives forever, as well as the solar panel — is less than one hundred dollars. So, one year of kerosene would pay for a solid-state lighting system,” he said. Now his aim is to develop a lower-cost lighting system. In January, Irvine is leaving the University of Calgary. He has also decided to start his own company in India.
