Article: A Battery's Nightmare Portable electronics that can be carried about easily are only as good as their batteries and, let's face it, batteries aren't very good, especially when compared with, say, petrol, which packs 100 times a battery's energy into an equal space. That's why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life! When the fuel runs out in your mobile phone, you just fill up and go. The engine---about the size of a ten-cent coin---starts with a combustion chamber that burns hydrogen. Its tiny parts are etched onto silicon wafers in the same manner that computer parts are etched onto integrated circuits . The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply. But the _ in all this nice detail is efficiency. Tiny engine parts don't always behave like the bigger parts of the first engine. Something between the parts can slow down the works, according to Columbia University Professor LucFrechette, one of the engine's designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine. The scientists' goal is to create an engine that will operate 10 times better than batteries operate. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren't likely until at least the end of the next ten years.

Article: Once upon a time a peacock and a tortoise became great friends. The peacock lived in a tree on the bank of the stream in which the tortoise had his home, and every day the peacock danced near the stream and displayed his gay plumage for the amusement of his friend. Unfortunately, one day a bird-catcher caught the peacock and was about to take him away to the market. The unhappy bird begged his captor to allow him to say goodbyeto his friend -- the tortoise. The bird-catcher agreed and took the peacock to the tortoise, who was greatly astonished when he saw his friend become a captive. The tortoise asked the bird-catcher to let the peacock go, but the bird-catcher laughed at his request, saying that was his livelihood. The tortoise then said, "If I give you a handsome present, will you let my friend go?" "Certainly," answered the bird-catcher. So the tortoise dived into the water and in a few seconds came up with a handsome pearl. To the bird-catcher's astonishment, the tortoise handed it to him. This was beyond his expectation, and he let the peacock go immediately. A short time later, the _ man came back and told the tortoise that he thought he had not been paid enough for the release of his friend, and threatened that unless he received another pearl which matched the first one, he would again catch the peacock. The tortoise, who had already advised his friend to go to a distant place on being set free, was greatly enraged at the greed of this man. "Well," said the tortoise, "if you insist on having another pearl like that one, give it to me and I will fish you out an exact match for it." The cupidity of the bird-catcher prevented his reasoning that "one in the hand is equal to two in the bed of the stream", and he quickly gave the pearl to the wily tortoise, who swam out with it, saying, "I am no fool to take one and give two!" and disappeared immediately, leaving the bird-catcher to be sorry for his greed.
