After years of false starts, with the first commercial sales possible within months, a new industry selling motor fuel made from waste is getting a big push in the United States. Many companies have announced plans to build plants that would take in material like wood chips, garbage or crop waste and turn out motor fuels. For decades scientists have known it was possible to convert waste to fuel. But success is far from assured. Some of the latest announcements come from small companies whose dreams may be bigger than their bank accounts.They are counting on billions in government funds. Big technological problems remain, and even if they can be solved, no one is sure what unintended consequences will emerge or what it will really cost to produce this type of fuel. Virtually any material containing hydrogen, carbon and oxygen could potentially be turned into motor fuel.That includes plastics, construction debris (废渣), forest and lawn trimming (修剪下来的废料), wood chips, wheat straw and many other types of agricultural waste.The potential fuels include ethanol(乙醇), which can be blended with gasoline, or other liquids that could displace gasoline entirely. Much of the new money flowing into the fields is coming from Silicon Valley, where the venture capitalists who gave the world the Internet revolution see an opportunity to do something similar with the fuel supply. What has been done is small in the scheme of American fuel demand, but it may set the stage for important growth if those first projects prove that the economics can work.

What is happiness? Most researchers agree that it involves an assessment(评价) of the good and bad in our lives. It is the emotional balance sheet we keep that allows us to say honestly whether we are living a happy life, in spite of bad things now and then. Marriage has taken a lot of hits since the 1960s. It has been said to hold many people, especially women, back from their full potential to be happy. Don’t believe it. In 2004, 42 percent of married Americans said they were very happy. Just 23 percent of never-married people said this.The happiness numbers were lower for other groups: only 20 percent of those who were widowed (死了丈夫或妻子的), 17 percent of those who were divorced, and 11 percent of those who were separated but not divorced said they were happy. Overall, married people were six times more likely to say that they were very happy than to report that they were not too happy. And generally speaking, married women say they are happy more often than married men. Marriage isn’t just associated with happiness—it brings happiness, at least for a lot of us. One 2003 study that followed 24,000 people for more than a decade showed a significant increase in happiness after people married. For some, the happiness increase wore off in a few years, and they ended up back at their pre-marriage happiness levels. But for others, it lasted as long as a lifetime.
