Stu­dent de­signs a cheap home heater

China Daily (Hong Kong) - - NATION DIGEST -

A col­lege stu­dent in Nan­ning de­signed an eco­nom­i­cal way to raise a room’s tem­per­a­ture us­ing or­di­nary can­dles, bricks and flow­er­pots. He posted pic­tures show­ing the step-bystep pro­ce­dure on the In­ter­net. The sim­ple com­bi­na­tion can in­crease the tem­per­a­ture of a 10-square-me­ter room by 12.5 C in 40 min­utes. The in­for­ma­tion has spread widely on the In­ter­net.
