Tong Wei and Liu Hanyuan discuss nuclear fusion power generation: they hope it happens, but also worry about it happening.

News on November 19th. At the First Photovoltaic CTO Summit and Technology Innovation Conference of the 8th China International Solar and Energy Storage Industry Conference in 2025, Liu Hanyuan, the chairman of Tongwei Group's board of directors, talked about nuclear fusion. He said that the prospect of artificial sun generating electricity in the laboratory at low cost and high efficiency is both hoped for and worrisome. Hoping for it to happen is hoping for technological breakthroughs, but worrying is that it would revolutionize the solar industry and everyone would have to change careers. He mentioned that Chinese scientists have progressed from the first generation to the second generation and are currently building the third generation of Tokamak devices. It is possible that by the end of next year or the year after, a commercial fusion reactor producing 20 to 200 megawatts of electricity could be completed, which sounds exciting but also precarious. "The materials aspect is still very terrifying, scientists are working on superconducting coils and new loop paths, and the construction and development look very impressive overall. If we make progress a bit slower, when fusion energy becomes a reality, we won't need to install solar panels anymore," Liu Hanyuan said. "Perhaps the era still leaves this opportunity for us."
