        "summary": "China's researchers have achieved a notable advance in space-based solar power, developing a ground-based test system for wireless power transmission and demonstrating 20.8% efficiency at 100 metres, including powering a drone test at 30 metres. The Sun Chasing (Zhuri) project aims to collect solar energy in orbit and beam it back to Earth or to spacecraft, with orbital testing planned as the next step.",
        "content": "<p>Xi\u2019an, China \u2014 Chinese scientists have taken a major step toward\ndeveloping space-based solar power plants that could one day beam energy\nback to Earth or to spacecraft. A research team from Xidian University\nin Shaanxi Province, northwestern China, made significant progress in\nthe Sun Chasing project, or Zhuri in Mandarin. The team has developed a\nground-based test system for wireless power transmission capable of\ncharging several moving targets simultaneously. In recent tests, the\nsystem achieved a wireless power transmission efficiency of 20.8 percent\nfrom direct current (DC) to DC at a distance of 100 metres, delivering\n1,180 watts of power. The researchers have also built a wireless\ncharging system for drones. In one test, a drone flying at 30 kilometres\nper hour was able to receive a stable 143 watts from a distance of 30\nmetres. Space-based solar power plants operate as the name suggests: an\nenormous array of solar panels placed in outer space. The plant would\ncollect sunlight in space, where the Sun is constantly shining, and then\nconvert that energy into microwaves or lasers to be beamed back to Earth\nor directly to satellites and space vehicles. This method could address\ntwo major challenges: supplying uninterrupted power for space missions\nand addressing the energy crisis on Earth. Previously, in 2018, the\nresearch team launched the first phase of the Sun Chasing project to\nbuild a ground test facility. Then in June 2022, they completed a ground\nvalidation system with full link and the world\u2019s first end-to-end system\nfor space-based solar power. Now the team has moved to the second phase.\nThe current aim is to tackle the challenges of generating high power in\nspace and transmitting it efficiently over long distances. According to\nDuan Baoyan, a specialist at Xidian University and an academician of the\nChinese Academy of Engineering, the latest breakthroughs include\nimprovements in the efficiency of solar energy collection and\nconversion, higher precision in microwave beam control to reduce energy\nlosses, and the manufacture of lighter transmitter and receiver\nantennas, which are crucial for space applications. The team has also\nsolved the problem of supplying power to multiple moving targets\nsimultaneously using a single transmitter. This means that in the\nfuture, a single space-based power plant could supply electricity to\nseveral satellites or vehicles on Earth at once, Duan added. Duan noted\nthat there is still a long way to go before space-based solar power\nbecomes commercially viable. The next step, he said, is orbital testing.\nHe hopes to contribute China\u2019s knowledge and solutions to support the\nglobal energy transition and sustainable development.<\/p>",
