Editor's introduction: Dun Tianrui is included in the 'Pattern' section not because of his company's scale or wealth, but because he chose a path less traveled—turning high-altitude wind power from science fiction into reality over eight years in the no-man's land of new energy. His pattern is reflected in his foresight of the technological endgame: while the industry focused on ground-based wind power, he saw the potential of high-altitude wind energy; while his peers sought stability, he sold his wedding house and went all in. This belief-driven long-termism and keen judgment of industrial trends are the archival values this section aims to preserve.
Dun Tianrui's entrepreneurial journey began in 2018 when he was studying directing at Communication University of China. Driven by the AI wave and a dream from high school, he decided to drop out and co-found a venture with his high school classmate Weng Hanke to develop high-altitude wind power. Neither had a professional background, but they entered this technological no-man's land by studying literature and visiting research institutions. In the early stages, funding was tight; Dun sold his wedding house to raise 2 million yuan in startup capital. The first aerostat burst upon ascent, but the team persisted, and in 2020 the second aerostat successfully reached 100 meters. In 2022, the team completed core technology validation of the S500 prototype. In June 2023, Beijing Linyi Yunchuan Energy was officially established, with Dun as CEO. That year, they launched the S1500 MW-class commercial floating wind power system, the world's first grid-connected MW-class product, securing orders worth nearly 500 million yuan. In January 2026, the S2000 successfully ascended to 2000 meters and completed grid-connection validation, marking the transition of high-altitude wind power technology from validation to commercial application.

Dun Tianrui's business philosophy centers on 'finding certainty amidst uncertainty' and using technology to create real value. Facing technical challenges, he led the team in a cycle of 'failure, review, and retry,' from the aerostat burst to the successful ascent of the S2000, demonstrating resilience. When funds were tight, he sold his wedding house, showing determination. He emphasizes collaboration with domestic research institutions, partnering with Tsinghua University, the Chinese Academy of Sciences, and the Aerospace Information Research Institute, leveraging China's complete industrial system to jointly develop core components like lightweight motors and DC power systems. The success of the S2000 in 2026 was not only a technical breakthrough but also a result of teamwork and industrial synergy. Dun has set a goal to reduce the levelized cost of electricity to 0.03 yuan by 2028, reflecting his pursuit of cost efficiency. [1]
Dun Tianrui, as a post-95s entrepreneur, is regarded as a rising force in the new energy sector. He led his team to push high-altitude wind power from a sci-fi concept to industrial reality, setting industry records. The successful ascent of the S2000 to 2000 meters and grid-connection demonstrated China's innovative capability in new energy technology. His story inspires many young people, proving that non-professional backgrounds can achieve breakthroughs in hard tech. Linyi Yunchuan Energy's technological achievements have gained support from professional investment institutions and national capital, and collaborations with top research institutions have advanced China's high-altitude wind power technology. Dun's persistence and innovation have opened new possibilities for China's green power and provided a Chinese solution for global new energy development. [1]
The business proposition Dun Tianrui leaves behind is: how to transform cutting-edge technology into a sustainable industry? He spent eight years proving the feasibility of high-altitude wind power, but the real test lies in cost and scalability. The goal to reduce the levelized cost of electricity to 0.03 yuan by 2028 is his projection of the industry's endgame. His story reminds us that true pattern is not about where you start, but about your judgment of the future and your persistence. The wind is high in the sky, and the road is underfoot. Dun's archive records how a young entrepreneur used belief and action to open new possibilities for China's green power.
