英语播客 A Cup of English 61 A Glowing 'Starpath'

'Luminous', 'glowing', 'radiating' are the words which came to my mind(1) after reading an article about a very special, new technology. It's called 'Starpath', an earth-friendly(2), inexpensive, and efficient way to light our streets. A company in England called Pro-Teq Surfacing, has developed a material made out of ultraviolet particles. These particles are spread onto a path, where they absorb sunlight during the day, and then they glow(3) blue at night. The first public demonstration of this took place in the city of Cambridge. I found a photograph of the path in the newspaper called 'The Telegraph', and it does show the path glowing at night. This is a very exciting development in lighting because it is clean, sustainable(4), and very cheap. I can imagine the cost of lighting our streets with traditional street lamps. However, this Starpath technology could cut our national lighting costs by hundreds of millions each year. We certainly cannot do without(5) light at night, to keep us safe, to help us find our way home, and to discourage crime. What a fantastic development. And this is just the beginning. Starpath technology offers the possibility of different colors of light as well. Also, the material used can last up to seventy years, so it is very sustainable stuff. As councils are turning off street lamps to save money and to meet carbon emissions targets, Starpath could be a valuable solution to both problems.
