Cooling the servers can be costly. So researchers asked what would happen if the heat created by the servers could be captured and used? Data centers of large Internet companies such as Google and Microsoft have thousands of computer servers. As these servers process information, they create large amounts of heat, so they need huge cooling systems. These systems send the heat into the air. The Dutch company Nerdalize thinks paying for electricity to operate the servers and then paying again to cool them is a waste of energy. So it developed a device called the e-Radiator. It is a computer server that also works as a heating source. Boaz Leupe is the 1225 chief executive officer of Nerdalize. He says the e-Radiator saves money because companies don't have to pay to cool their servers. \kilowatt(于瓦）hour you are using is used twice-once to heat the home and once to compute the client's task without the cooling overhead. \He says five homeowners in the Netherlands are testing the heating device in their homes. \reimburse the electricity the server uses, and that we can do because of the computer clients on the other side, and, in that way, homeowners actually get heating for free, and computer users don't have to pay for the overhead of the data center. \Jan Visser is one of the participants in the year-long experiment. He says the amount of heat produced by thee-Radiator depends on the work being done by the computer server. He says it cannot be used as the primary source of heat. But he is ready to try it. He says if it provides enough warmth, he will be able to use his home's heating system less, which will save him money. Nerdalize says e-Radiators create heat temperatures of up to 55°C. It says the devices could save users up to $ 440 in heating costs a year. 21. Why did researchers ask what would happen if the heat created by the servers could be captured and used? A. Because computers can get very hot. B. Computer servers is a complex program. C. Cooling computer servers costs a lot of money. 22. The computer servers in large Internet companies such as Google and Microsoft can A. create large amounts of information B. create large quantity of heat C. manage the huge cooling systems 23. Nerdalize developed the e-Radiator because A. e-Radiator cost less energy C. e-Radiator can create cold air for free 24. According to Jan Visser, the amount of heat produced by thee-Radiator A. depends on the work being processed by PC B. cannot be used as the home's heating system C. cannot be used as the main source of heat 25. The best title for this passage wonld be \A. The New Way to Heat Homes B. The New Way to Cool Homes C. Hot Computers Could Be Used for Free 1226 _. B. e-Radiator can cool the servers for free \
