  Onions make you cry,add flavor to food and are praised for their medical benefits. Now the vegetable has another use―powering up green energy.

  A new system was first used on Friday that converted onion juice into electricity at Gills Onions,the largest fresh onion processor in the United States.

The Oxnard,Californiabased company expects its new onionfueled power to reduce its electric bill by $700,000 a year and cut its annual greenhouse gas emissions by up to 30 ,000 tons.

  The happy ending to this green energy tale,however,started with another question：how to get rid of onion waste.

  "When we peel an onion,35 to 40 percent of the onion comes off before we have a usable onion. That's the top,tail and skin around the onion before you get to the meat," said Steven Gill,coowner of the 25-year-old company.

  They used to put the waste into the fields for composting,but that became a problem. Ten years ago,Gill started looking at technology for a solution.

  "We ended up cutting up the skins as they come out of the plant and extracting all the juice,which is very high in sugars,and bacteria love that stuff," Gill said.

In the new system,bacteria produce methane gas from the juice. The gas then goes to two 300-kilowatt fuel cells,creating enough power for 460 homes. The company expects to get 35-40 percent of its electricity from the onsite generator.

  The company invested $9. 5 million in the project and will receive $ 2. 7 million from Southern California Gas Co.，as part of a state program to encourage selfcontained generation by businesses. In addition to cutting its electric bill,the company will save $400,000 in trans?port expense and expects payback in six years.

 Thomas Alva Edison was the most famous inventor in American history. He had 1 ,093 pa?tents in a wide range of fields,including telecommunications,electric power,sound recording,motion pictures,primary and storage batteries,and mining and cement technology. As impor?tant,he broadened the notion of invention to encompass what we now call innovation―inven?tion,research,development,and commercialization and invented the industrial research labora?tory. Edison's role as an innovator is evident not only in his two major laboratories at Menlo Park and West Orange in New Jersey but in more than 300 companies formed worldwide to man?ufacture and market his inventions,many of which carried the Edison name,including some 200 Edison illuminating companies.

  Edison was born in 1847 in the canal town of Milan,Ohio,the last of seven children. He attended school briefly but was principally educated at home by his mother and in his father's li?brary. In 1859 Edison began working on a local branch of the Grand Trunk Railroad,selling newspapers,magazines,and candy. At one point he printed a newspaper on the train,and he also conducted chemical experiments in a baggagecar laboratory. By 1862 he had learned enough telegraphy to be employed as an operator in a local office.

  From 1863 to 1867 he traveled through the Midwest as a telegrapher. During these years he read widely,studied and experimented with telegraph technology.

In the fall of 1878,Edison devoted thirty months to developing a complete system of incan?descent electric lighting. During his lamp experiments,he noticed an electrical phenomenon that became known as the " Edison effect". In World War I,the federal government asked Edison to head the Naval Consulting Board,which examined inventions submitted for military use. Edison worked on several problems,including submarine detectors and gun location techniques.

  By the time of his death in 1931,Edison had received 1 ,093 U. S. patents,a total still un?touched by any other inventor. Even more important,he created a model for modern industrial research.

  There was once a man who had four sons. He wanted his sons to learn not to 1        things too quickly. So he sent them each on a quest,2       ，to go and look at a pear tree that was a great distance 3       . The first son went in the winter,the second in the 4       ,the third in summer,5       the youngest son in the fall.

  6       they had all gone and come back,the father called them together to 7        what they had seen. The first son said that the tree was 8       ,bent,and twisted. The second son said that it wasn't 9        and it was covered with green buds and full of 10.        The third son disagreed;he said it was laden with blossoms that 11        so sweet and looked so beautiful,it was the most 12        thing he had ever seen. The last son 13        with all of them; he said it was 14        and drooping with fruit,15       of life and fulfillment.

  The man then 16        to his sons that they were all right,because they had each seen 17        only one season in the tree's life. He told them that you cannot judge a tree or a 18       by only one season,and that the essence of who they are and the pleasure,joy,anger and 19        that come from that life can only be 20        at the end,when all the seasons are up.
