So researchers asked what would happen if the heat created by the servers could be captured and used Data centers of large Internet panies such as Google and Microsoft have thousands of puter 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 pany 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 puter server that also works as a heating source. Boaz Leupe is the chief executive officer of Nerdalize. He says the e-Radiator saves money because panies don't have to pay to cool their servers. "The kilowatt（千瓦）hour you are using is used twice -- once to heat the home and once to pute the client's task without the cooling overhead." He says five homeowners in the Netherlands are testing the heating device in their homes. "We reimburse the electricity the server uses, and that we can do because of the puter clients on the other side, and, in that way, homeowners actually get heating for free, and puter 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 the e-Radiator depends on the work being done by the puter 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℃. It says the devices could save users up to $440 in heating costs a year. Why did researchers ask what would happen if the heat created by the servers could be captured and used 1 A.
