Bright ideas
Do you have bright ideas? Ideas or inventions that change society or, at least, make life easier for somebody? Perhaps we all do sometimes, but we don’t often make the idea a reality. Recently, in Britain, there was a competition called British designers for tomorrow. The competition encourages young people to carry out their bright ideas. There were two groups in the contest; group one was for schoolchildren under 16; group two fro schoolchildren over 16. And there were eleven prize-winners altogether.
Neil hunt, one of the prize-winners, was called “sunshine superman”. It’s important when people study the weather to be able to record sunshine accurately. We need to know how many hours of sunshine we have and how strong it is. Most sunshine recorders only record direct sunlight. Neil’s is more accurate (精确的) and this is very important for research into the way of using solar (太阳的) power.
You can do so much with cartoon. Look at Simon West’s idea for animated(动画的) road signs. He uses pictures which appear to move as you go nearer to or father from them. This isn’t a new idea. But it is new to use these pictures on road signs. “We found that people were more likely to see moving signs,” said Simon. So now, you can really see rocks falling, trains moving, horses running or a car falling over the edge of a cliff (悬崖). Quite a warning!
The ideas in the competition were so inventive that we are surprised that British industry doesn’t ask more schoolchildren for suggestions. Perhaps this will be the start of “pupil power!”
