China Plans Ambitious 'Three Gorges Dam of Space' for Solar Power

CN
Published:

China has announced an ambitious initiative to construct a massive solar power array in geostationary orbit, referred to as the 'Three Gorges Dam of Space.' The concept, outlined by renowned Chinese rocket scientist Long Lehao, involves deploying a solar array one kilometer wide and positioned 36,000 kilometers above Earth. This project aims to harness solar energy uninterrupted by the planet's day-night cycle and weather conditions.

Long compared the potential energy generation of this space-based solar initiative to that of the Three Gorges Dam, which currently generates around 100 billion kilowatt-hours annually. He stated, "The energy collected in one year would be equivalent to the total amount of oil that can be extracted from the Earth."

To realize this project, advancements in China's space technology will be necessary, including the development of super heavy rockets. Long's team is working on the Long March-9 rocket, which is expected to reach a height of 110 meters and carry up to 150 tonnes to low Earth orbit. This surpasses the lifting capacity of NASA's Saturn V and Space Launch System heavy-lift rockets.

While space-based solar power has been a topic of discussion in scientific circles for decades, China's plan represents a significant step towards making this concept a reality.

Scientists Discover Chorus Waves Farther from Earth Than Ever Before

A groundbreaking study has revealed the presence of chorus waves, typically known to occur 32,000 miles from Earth, at an unprecedented distance of 102,500 miles, more than three times further than previously recorded. According to researchers at Beihang University in China, who published their findings in the journal *Nature*, these waves potentially indicate that energetic electrons and related phenomena could be widespread in the universe, wherever magnetic fields exist. Chorus waves are disturbances in the Earth's magnetic field that generate fast-moving electrons, often referred to as "killer electrons," which pose risks to spacecraft by potentially damaging their systems. James Burch, principal investigator for NASA’s Magnetospheric Multiscale (MMS) mission, underscored the significance of this research, emphasizing its implications for future space missions to the Moon, Mars, and beyond. The discovery implies that the effects of these energetic particles are more extensive than previously recognized, necessitating enhanced shielding against them for human space exploration.

Chinese AI Firm DeepSeek Stuns Silicon Valley with Advanced Model

Chinese artificial intelligence company DeepSeek has captivated Silicon Valley following its launch of a powerful AI model that challenges U.S. technological dominance. Despite U.S. restrictions on exporting advanced chips to China, DeepSeek's founder Liang Wenfeng revealed that the company had stockpiled between 10,000 and 50,000 Nvidia A100 chips before the ban. This inventory allowed DeepSeek to develop a model at a fraction of the cost compared to American counterparts. According to experts, while the U.S. government's export controls posed significant challenges, they have also prompted innovation within the Chinese tech sector. Marina Zhang, an associate professor at the University of Technology Sydney, noted that these restrictions have driven companies like DeepSeek to maximize resources and foster creativity. Liang, 40, is hailed as an "AI hero" in China, leading a team of fewer than 140 engineers—most sourced from elite universities. The release coincided with heightened tensions in U.S.-China relations, signaling Beijing's resolve to position itself as a tech superpower. However, the long-term efficacy of DeepSeek amid new restrictions remains uncertain.

Scientists Discover 'Killer Electrons' Farther Than Ever From Earth

A new study led by Beihang University scientists reveals that "chorus waves," which produce dangerously high-energy electrons, have been detected more than three times further from Earth than previously thought—at an astonishing distance of 165,000 kilometers (approximately 102,500 miles). These findings, published in the journal Nature, suggest that chorus waves can be generated by changes in magnetic field frequencies, rather than only near planetary magnetic fields, according to co-author James Burch, principal investigator of NASA’s Magnetospheric Multiscale (MMS) mission. Previously, researchers detected chorus waves only at a maximum distance of 51,000 kilometers (about 32,000 miles). These high-speed, energy-laden particles can penetrate spacecraft shielding, posing a significant risk for human spaceflight missions to destinations like the Moon and Mars. “This is a new source of energetic electrons that we didn’t know about that can occur everywhere,” Burch stated, emphasizing the implications for future exploration. Understanding the behavior of these particles will be crucial for ensuring the safety of astronauts in deep space.
