阿里·哈吉米里: 來自太空的無線能源如何為所有設備供電

來自太空的無線能源如何為所有設備供電

現代生活十分依賴無線科技。 如果我們的設備可以無線供電，會是怎樣的景況？ 電氣工程師阿里·哈吉米里（Ali Hajimiri）解釋無線電力傳輸背後的原理，並分享了他的遠大願景：將柔性太陽能電池板發射到太空，收集陽光，轉為電能，然後將其傳回地球。 邀請你來了解這項科技將如何為一切提供動力，並從太空照亮我們的世界。

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.
