阿里·哈吉米瑞（Ali Hajimiri）: 来自太空的无线能量如何点亮万物

来自太空的无线能量如何点亮万物

当代生活依赖于无线技术。如果为我们的设备供电的能量可以以无线的方式传输，会怎么样？电气工程师阿里·哈吉米瑞（Ali Hajimiri）解释了无线能量传输背后的原理，分享了他的先进畅想：向太空发射柔性的太阳能板，收集太阳光，将其转化成电力，再发射回地球。来听一听这项技术如何点亮万物，从太空点亮我们的世界。

Wireless energy transfer could reshape how the world is powered by sending electricity through the air, much like data travels today. Using synchronized arrays of small antennas, energy can be focused and targeted with precision—enough to power a moving light bulb, a battery-less drone, or even entire communities. Flexible solar panel satellites could someday orbit Earth, harvesting sunlight eight times more efficiently than ground panels and delivering clean power anywhere, even to disaster zones. By turning science fiction into reality, this vision promises to democratize access to energy on a global scale.
