Taiwan, South Korea and China have critically low fertility rates below 1.0. Japan is also very low (1.15) and has had low fertility for longer. By 2070, the countries could halve their current populations. A fertility rebound could avert 30-70% of projected population losses by 2100. This might stabilizing societies at near-current sizes—but only if …
China is starting production of a new stealth fighter the J-35. It is less stealthy than the F-35 but is more stealthy than other Generation 4 or 4.5 fighters. The J-35 is a close copy of the F-35 in design (e.g., blended wings, DSI inlets) but is larger, faster (Mach 2.0 vs. 1.6), and twin-engine …
China’s room temperature superconductor research continues. Here is the latest published work from the team from multiple universities and labs. This is the same teams that found stronger magnetic indications of Meissner effect in LK99 variant materials. Through heavily doping sulfur into an apatite framework, chinese researchers synthesized a new blend mainly comprising variant apatite …
The pursuit of room-temperature superconductivity has long been a holy grail in the field of condensed matter physics because it could revolutionize all electricity based technologies and in particular make computers at least hundreds of times faster. In mid-2023, the Korean LK-99 (copper-substituted lead apatite) material provided a controversial possibility of a major breakthrough. Researchers …
South Korea plans a 120 Gigawatt space based solar project which would generate more power than the US nuclear industry’s 95 gigawatt. Two Korean research institutes are designing a space solar power satellite project with the aim of providing approximately 1000 TWh of electricity to the Earth per year. The 95 gigawatts of nuclear in …
Unit 2 of the Shin Hanul nuclear power plant in South Korea has entered commercial operation, Korea Hydro & Nuclear Power (KHNP) announced. The unit is the second of two APR-1400 reactors at the site, with a further two planned. Georgia Power has announced the start of commercial operations at the second of the two …
New video from SCTL Korea room temperature superconductor experimenters claimed to shows a very strong full levitation effect. Full levitation would be evidence of the Meissner effect found only in superconductors. I have shown how the levitation evidence was originally partial levitation. Critics says partial levitation can be from diamagnetics or even some iron contamination. …
One of the Korean researchers working on room temperature superconductors shows a sample with some possible magnetic locking effects. The phenomenon occurred when he found and cut out a part of the sample that was felt to have strong diamagnetism. He does not know if the effect can be explained by Lenz’s law. He thinks …
Investigation of the zero resistance and temperature-dependent superconductivity phase transition in Pb-Cu-P-S-O compound by Huk Geol Kim, Dae Cheol Jeong and Hyun-Tak Kim. Hyun-Tak Kim is one of the lead researchers for the LK99 team. This new paper presents a specific critical temperature for PCPOSOS, demonstrating consistency with the original authors’ data. In this study, …
Motional, a global leader in driverless technology, and Hyundai Motor Group launched IONIQ 5-based robotaxi Motional’s next-generation robotaxi. They added LIDAR and other sensors to all-electric Hyundai IONIQ 5. The IONIQ 5 robotaxi is an SAE Level 4 autonomous vehicle that can safely operate without a driver. It’s a zero tailpipe-emissions robotaxi and represents the …
Two weeks ago the Korean group presented new room temperature superconductivity research and this week the Chinese research group published new research on LK99 type superconductors. Are we at a breakthrough? What has been done in this new research? China has published new research on improved copper and sulfur codoped material with a stronger meissner …
