on 22nd the morning, the Fengning subdistrict office has held the technical week activity in the parental affection plot, had demonstrated from Kunming 24 several junior high pupils the energy conservation reduces the row of technical small invention. Besides the demonstration science and technology creation, schoolmates and the related staff also introduced for the resident reduces the row of technical knowledge about the energy conservation.
In the technological activity week,unique baby gifts make, the Kunming 24 students to the resident were introducing that they conserve energy reduce the platoon the small invention - - to conserve energy the water tank.
9:30 am activities just started, Kunming 24 third day student Dong Yang and his schoolmate lifts a saving water installment went on stage, although this hydraulic engine insufficient 1 meter high, actually has many pipes. It gathers the water tank is with the aluminum system,recommended baby dolls, the behind also some power point. and the temperature demonstration idea, lays aside together the machine under the sunlight merely several seconds time then feels the aluminum system water tank very scald one's hand.
According to Schoolmate Dong foreign introduced that this hydraulic engine's water tank can install 5 kilograms water, the hydraulic engine gathers depends entirely on this aluminum system water tank hotly, if the sunlight suffices,little girls clothes, so long as this hydraulic engine more than 1 hours, the water temperature may amount to 80 degrees. Sun's undercapacity, but may also use electricity carries on the heating. This machine they spent a half year to complete, was a Taiwan Telegraphic Transmission adds the water heater and solar-powered water heater's mix, the superiority lets each water drop is hot. Because the traditional solar energy the pipe exposes to air in the air,（Related Articlesluxury gifts for kids How to implement in the fami）, will therefore have the massive cold water will be before the hot water emits, has wasted the water resources enormously. This festival hydraulic engine has established a return line, carries on the heating once more this part of cold water backflow to the water tank, like this flows out Shui Jiudu was hot. In addition, so long as periodic cleaning water tank, then not only may use for after the heating water to wash rice, cooks a meal and so on, but may also drink.
