①An energy company in Sweden has started a project to heat up the city of Västeras using large underground caves(洞穴) full of warm water — like a huge hot water bottle under the streets.
②The energy company, Mälarenergi, will use large caves that already been there and can hold almost the same amount of water as 120 Olympic- sized swimming pools. Around 40 years ago the caves were used to hold large amounts of oil, in case it was needed for fuel(燃料). However, the caves were emptied in 1985 and they haven't been used to store anything since then.
③Mälarenergi is cleaning the caves before it fills them with water, which will be heated up to 95℃ using heat from Mälarenergi's nearby power station. The thick rock holds the heat and will keep the water warm even in winter. An instrument called a heat exchange r will warm the water and will turn the heat into another liquid(液体) when it is ready to be used. This liquid will then travel into people's heater through the local heating network, which supplies warmth for 98% of the households in Västeras. The town is home to 130,000 people.
④The system should help the company to carry on providing heat for customers, even on really cold days when lots of people turn on the heating. The company hopes it will be a useful way to warm homes, with less waste, because it will be difficult for the heat to run away from underground.
⑤ In Finland, a system like this is already in use, providing 25,000 homes with heat from underground caves. Some scientists think it could be used in the UK. About a quarter of the British population live above coal mines(煤矿) that are no longer used. Over the years, lots of these man- made caves have been covered in water and the natural warmth underground has kept the water at a temperature of around 15℃. The water could be warmed up even more by using a heat machine and sent to nearby houses to heat them. This method has already been used before in England.
①Clean the caves.
②Heat the water up to 95℃.
③Fill the caves with water.
④Send the liquid to people's house.
⑤Turn the heat into another liquid.
Inventions are very important and they can easily change our life. The followings are some great inventions.
