A Battery's Worst Nightmare(噩梦)

  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! W hen the fuel runs out in your laptop or mobilephone, you just fill up and go.

  The engine, about the size of a ten-cent coin, starts with a combustion chamber(燃烧室)that burns hydrogen(氢). Its tiny parts are etched onto silicon wafers(硅片) in the same manner that computer parts are imprinted onto integrated circuits(集成电路). 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 devil in all this nice detail is efficiency(效率). Tiny engine parts don't always behave like their scaled-up parts of the first engine. Something between the parts can slow down the works, according to Columbia University professor Luc Frechette, 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 at 10 percent efficiency-that is, 10 times better than batteries operate. Frechette says that a complete system, with all parts of place and working, will be set up in the next couple of years, but commercial models aren't like until at least the end of the next ten years.

1.According to the passage, the title suggests that ________.

[  ]

Howling is a behavior commonly observed among a wolf nark. An animals, wolves work together to hunt and rely on howling was an important means of communication each other. There are different explants of a wolf’s howl and it appears that there may be more to discover.      One theory is that wolves howl to bend better together. It’s almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together . But this theory may be wrong, explains Fred H. Harington, a professor who studies wolf behavior.     Indeed, there have been tines when wolves have been seen one moment howling in a exhorts, and the next, quarreling anions each other. It appears that usually the lowest-tanking menthes of the pack may actually be “punished” for
Joining in the churs at times. So is howling a way to strcagthen a social boad or just a way to reconfirm status among its members? ——Why do welves howl for sure?
What is cleat, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that woloves may separate from one another at times. When this happens, howling appcars to be an ercellent means of gathering.
Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occat in the morning, as if wolves were doing some sotr of “roll rall”where wolves all howl togeter to howl, very likely others will follow.
