美国科学家发现一种罕见的金属,能够吸收阳光并以热量的形式无限期存储,需要的时候再将存储的热量释放。这一发现为研制下一代太阳能装置铺平了道路,即能够利用太阳能并无限期存储热量。麻省理工学院的研究人员表示,这种金属可用于制造“可充电的热量电 American scientists discovered a rare metal that absorbs sunlight and stores it indefinitely as heat, releasing stored heat when needed. This discovery paved the way for the development of the next generation of solar devices that would use solar energy and store heat indefinitely. Researchers at the Massachusetts Institute of Technology said the metal can be used to make ”rechargeable calories
