When a computer runs a group of programs, it can get very Cooling the computer can cost a lot. So some scientist's wonder what will happen if the heat from the computer can be used.
Large Internet companies (公司) such as Google and Microsoft have thousands of computers. As these computers deal with information, they produce lots of heat, so they need huge cooling systems(系统). These systems send the heat into the air.
A company in Holland (荷兰) thinks paying to make the computers work and then paying again to cool them are a waste of energy. So the company developed a special device—the e-radiator.
Boaz Loupe, the head of the company, says the e-radiator works as a heating system and saves money. He explains that the energy is used twice—once to heat the home and once to cool the computer. So the users don't have to pay to cool their computers.
Five homeowners in Holland are testing the heating system in their homes.
"We pay for the computer using, so, in that way, homeowners get heating for free," Boaz says.
Jan Visor is one of the homeowners. "If you use the computer more the e-radiator produces more heat," he says. "It cannot provide enough heat if you don't use your computer often. "But he is ready to try it. It's a great help for his family.
The company says e-radiators can produce heat at a temperature of 55℃. It says the system can save its users about S 440 a year.
