阅读下面的短文，根据文中信息完成文后表格。（每空一词）
When computer servers (服务器) operate a large program, they can get very hot. Cooling the servers can cost a lot. So some scientists want to know what would happen if the heat created by the servers could be used.
Data (数据) centres of large Internet companies such as Google and Microsoft have
thousands of computer servers. As these servers deal with information, they produce lots of heat, so they need huge cooling systems. These systems send the heat into the air.
A company in Holland (荷兰) thinks paying for electricity to operate (使运行) the servers
and then paying again to cool them are a waste of energy. So it developed a device (装置) called the e-Radiator. It contains a computer server connected to the Internet. By placing these servers inside people’s homes instead of out-the-way data centres, the company hopes to heat homes from excess computer heat, while lowering costs for the computer users.
Five homeowners in Holland are testing the heating system in their homes. Jan Visser is one of them. He says the amount of heat produced by the e-Radiator depends on the work being done by the computer server. “It’s a great help for my family,” he says.
The company says e-Radiators produce heat temperatures of up to 55℃. It says the system
could save its users about $440 in heating costs a year.
