Seth DeBolt is a plant scientist at the University of Kentucky US. He and other scientists wanted to find a source of fuel that poor people in rural areas of developing countries could use to make electricity.
The United Nations Development Program says a billion and a half people have no electricity. A billion others have an undependable supply.
Professor DeBolt went on a study trip to rural Indonesia. He saw that there was very little waste in the use of agricultural products. Everything that farmers grew was used for something. Even the remains of fruit that people did not eat were fed to chickens.
Little waste meant there was little that could be used for fuel. Growing a separate fuel crop would take land away from food crops. That was something Professor DeBolt did not want to do.
DeBOLT said, "The people at most risk with respect to energy poverty, typically they're the same people who have food insecurity issues as it is. And then any change in availability would be most damaging to that group of people."
But he found one item that was in plentiful supply and would not create competition between food and fuel. Coconut shells are generally thrown out. Yet Professor DeBolt says it has an "excellent" heating value. All someone needs is a way to release that energy.
DeBolt says he and his team see possibilities for coconut power. "Coconuts are growing here and these are the areas where there is possibility for energy poverty to be eased at least in part by these small-scale production systems."
The researchers say these systems could provide as much as thirteen percent of the energy needs of a country like Indonesia. Other tropical countries with large crops of coconuts and similar fruit could benefit, as well.
But DeBolt says this is not a perfect solution. There are technical questions, like how to safely deal with the dangerous waste produced in the process. And there needs to be money to get these projects started.

Some expressions in English can be really puzzling. Have a look at the following to see how it challenges your brainpower.
Homeric laughter
The "Homer" in this expression is the Greek poet. People laugh differently. Some laugh silently, while others tend to laugh loudly. "Homeric laughter" refers to laughter of the latter kind. It is at times uncontrollable, and the entire body shakes during the process. This kind of laughter is called Homeric laughter because this is how the gods laughed in Homer's classics.
A three-ring circus
When you refer to a situation as being a three-ring circus, you are saying that it is a situation of complete confusion. There are so many activities taking place all together that they leave you confused or annoyed. The expression comes from the world of entertainment — the circus. The area where the artists perform their acts is called the "ring". In the past, some of the circuses were so grand that they had three acts taking place simultaneously in three different "rings". The audience had to decide which "ring" they wanted to focus on.
In the swim (of things)
When someone is in the swim of things, the individual is actively participating in the things happening around him, as in "I've been ill, but soon I’ll be back in the swim of thing." In the world of fishing, fishermen use the word "swim" to refer to the section of the lake/river where fish can be found in plenty. So, if you are a fisherman and wish to catch a lot offish, where would you be? You would be "in the swim".
Chickens have come home to roost
The word "roost" refers to the place where birds rest. It could be anything — the branch of a tree, a henhouse, etc. The expression is normally used to mean that the bad things that someone did in the past have come back to bite or upset the individual. In other words, one has to face the consequences of the deeds done in the past. The original form of this 700-year-old expression was "curses are like chickens; they always come home to roost".

Ever since Jerusha started her college, she began to write letters. Through a series of letters, from freshman to senior in college, she shared her life and study with an unknown gentleman, who never wrote back. Here is the very first letter.
|
Dear Mr. Kind, Here I am! I traveled yesterday for four hours in a train. It's a funny experience. I never rode in one before. College is the biggest, most confusing place — I get lost whenever I leave my room. I will tell you more later when I'm feeling less puzzled. Now I want to write a letter first just to get me familiar to you. It seems strange to be writing letters to somebody you don't know. It seems strange for me to be writing letters at all — I've never written more than three or four in my life, so please overlook it if they are not a model kind. Before leaving yesterday morning, Mrs. Lippett and I had a very serious talk. She told me how to behave, especially towards the kind gentleman who is doing so much for me. I must take care to be very respectful. I have been thinking of you a great deal this summer; having somebody take an interest in me after all these years makes me feel as though I had found a sort of family. It seems as though I belonged to somebody now, and it's a very comfortable feeling. I must say, however, that when I think about you, my imaqination has very little to work upon. There are just three things that I know: I .You are tall. II .You are rich. III. You hate girl. I suppose I might call you Dear Mr. Girl-Hater. Only that's rather unpleasant to me. Or Dear Mr. Rich-Man, but that's unpleasant to you, as though money were the only important thing about you. Maybe you won't stay rich all your life; But at least you will stay tall all your life! So I decide to call you Dear Daddy-long-legs. I hope you won't mind. It's just a private pet name — we won't tell Mrs. Lippett. The ten o'clock bell is going to ring in two minutes. Our day is divided by bells. We eat and sleep and study by bells. There it goes! Lights out. Good night. You can see how strictly I obey rules due to my training in the John Grier Home. Yours most respectfully, Jerusha Abbott |

One cold rainy evening last October, as a medical student, I was in a hospital, gathering data
for my graduation paper.
Holding a patient questionnaire 34 some simple yes-or-no questions, I walked towards a 43-year-old patient who lay in bed alone. I was worried whether she would approve of my demands at such a late hour. 35 , she treated it with consideration. Soon I finished and prepared to leave. 36 I could stand up, she spoke up in a weak voice asking where I was from and why I was working so late in the evening.
Then she started talking about herself as well as her 37 , "My husband died about a year ago, 38 me the only breadwinner of my family. My pay as a cleaner is 39 enough for me and my three kids. I don't know what my children would be if something bad happened to me."
I didn't know what to say. I desperately tried to remember the lessons from a communication skills class I had taken years earlier, but my mind was 40.
Without realizing it, I had begun 41 her hand. Now that I didn't have anything to say, I just sat quietly while she talked. That's when it occurred to me that she was not expecting any 42 from me. She 43 wanted me to listen. All 1 did was nod my head as a way of showing my 44.
The conversation went on for about 20 minutes. Finally, she stopped talking. "I'm very sorry for keeping you here to listen to my problems, but I feel 45 now. I had no one to 46 out my problems to. Thank you so much, doctor."
Sometimes patients do not need expensive medicine or advanced technology. 47 , they just need someone with the 48 to lend an ear and spare a little of their time. For me, that is one of the best things a doctor can do for a patient, doesn't it?
