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!When the fuel runs out in your laptop or mobile phone, 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 work, 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 10 times better than batteries do. 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 available until at least the end of the next ten years.
