我们大家在夏日深夜都可能有过这样的经历,尽管太阳早已落山,但公园露天的水泥凳子照样还是烫乎乎的,让人难以落座。据此科学家设想:利用水泥装置先将太阳能以热能形式储蓄起来,然后到夜里再利用储蓄起来的热能发电。目前,德国科研人员已成功开发了一种水泥蓄热装置,可以把白天的太阳能储蓄到温度可达400℃的液态介质中。 All of us may have had such an experience in the middle of the summer. Despite the fact that the sun has long fallen, the open-air cement stools in the park are still hot and hard to seated. Based on this, scientists envisaged that the use of cement plant to save the form of solar energy in the form of heat, and then use the stored heat to generate electricity at night. At present, German researchers have successfully developed a cement heat storage device that can store solar energy in the daytime into liquid media at temperatures up to 400 ° C.
