Chinese firm launches water-based eVTOL vertiport to boost low-altitude transport​

The system is made in collaboration with CATL, and is the eVTOL sector’s first integrated sea-air

AutoFlight’s new system combines a “zero-carbon water vertiport” with eVTOL aircraft to expand air mobility across large water areas. By tackling challenges like limited site options, slow infrastructure deployment, and complex take-off and landing processes, the solution makes low-altitude transport more practical and scalable.

The water-based vertiport can be deployed quickly, offering a flexible alternative to traditional land-based hubs and helping move the low-altitude economy from concept to real-world operation.​

CATL-backed system aims to expand eVTOL infrastructure​

The system is made in collaboration with CATL, and is the eVTOL sector’s first integrated sea-air solution. The vertiport operates entirely on electricity, its wide deck doubles as a landing pad covered in solar panels, while the cabin functions as both a departure lounge and a technical control room. Together, these elements create a flexible vertiport capable of supporting eVTOL takeoffs, landings, and charging. The system also enables intelligent coordination and data sharing with aircraft.

The water-based vertiport supports multiple flagship eVTOL models, including the industrial “White Shark” the 2-ton cargo aircraft “CarryAll” and the 6-seat passenger craft “Prosperity” Combined, these vehicles and the vertiport create a fully integrated land–sea–air system, enabling fast point-to-point transport across diverse applications – from cargo delivery to passenger commuting – while expanding the reach and flexibility of low-altitude air mobility.

Interesting potential applications for law enforcement and coast guard use.

US-China Tension Fuels Decoupling in Tech Research, Study Shows
US-China collaboration in technology research has fallen steadily to the lowest in 20 years, a shift an Australian think tank warns could reshape global innovation vital to security and economic growth.
Only a quarter of China’s collaborations involve American researchers, down from over half a decade ago, according to the Australian Strategic Policy Institute’s Critical Technology Tracker, which analyzed over 7 million papers across 74 critical fields. Collaboration intensity — the share of co-authored work relative to overall output — has dropped back to 2005 levels, according to the report released Wednesday.
The retreat comes at a time when China now generates almost 40% of global research output and dominates most critical technologies. Past collaborations between the world’s two largest economies have produced advances ranging from genomics and earthquake monitoring to energy efficiency and agricultural productivity.
The Tracker also shows declining collaboration between China and US allies including Canada, Australia and the Netherlands, even as Chinese researchers deepen ties with partners including Pakistan, Saudi Arabia and Belarus.
Pakistan rose from virtually no collaboration in 2005 to become China’s seventh most significant research partner in 2019, driven by nanomaterials research. Saudi Arabia advanced to eighth place in 2024 from 46th in 2005, while Belarus climbed to 20th from 41st.
“The risk of bifurcation is not simply that democracies lose access to Chinese research; it is that they lose the ability to steer global technological development,” said Stephan Robin, the report’s author. “Avoiding that outcome, it demands recoupling on new terms, built around trusted networks.”
The decline in US-China research collaborations began after the US Justice Department launched the China Initiative in 2018, subjecting such work to national-security scrutiny aimed at curbing intellectual property theft and curbing technology transfer. Although the Biden Administration dismantled the China Initiative in 2022, restrictions have continued.
Congress is now weighing measures to revive the China Initiative and impose sweeping bans on joint research. That would further accelerate the decoupling trend, even as China consolidates its lead in 57 of the 64 tracked technologies, spanning advanced materials, manufacturing and telecommunications.
This disengagement extends beyond the US, as America’s allies also become cautious about working with China. In Australia, growing concerns prompted various initiatives between 2018 and 2024 to strengthen risk assessment frameworks and funding for research projects involving China-based collaborators declined from a peak of A$90 million ($58.2 million) in 2019 to A$33 million in 2024. In the UK, similar risk assessment has also led to significant funding cut to collaborative research projects with China.

The largest international vaccine deal for a Chinese pharmaceutical firm so far:
Sinovac Clinches USD700 Million Brazil Deal, Setting New Record for Chinese Vaccine Exports
...
Sinovac will work with its local partner Tecpar, the technology institute for the Brazilian state of Paraná, and Eurofarma, a major pharmaceutical company in the South American country, to build a vaccine industrial platform and supply about 60 million doses of chickenpox and rabies vaccines, the Beijing-based company said yesterday.

Interesting way to say that they make a carbon-based nanoparticles that absorb radar energy.

A tried-and-true playbook, executed at bigger scale.

Many in the West don’t want to accept the fact that many of the essential ingredients in China’s manufacturing domination are

. The country has closely followed the proven economic model of the Asian Tigers, only this time with an order of magnitude increase in population and scale. Acknowledging and addressing this simple business model reality is the key to developing an effective American response.

Over the decades, Japan, Singapore, South Korea, Taiwan, and China all adopted the same economic development formula: excellent mass education, elite technical training, a compliant and low-cost workforce, substantial subsidies, government R&D support, a manufacturing export focus, initially protected domestic markets, access to foreign investment and intellectual property, modern infrastructure, high savings, low crime, an effectively engaged state, and especially bottom-up industry strategies initially focused on low-end commodity products.

Chinese Academy of Sciences achieves breakthrough in large-aperture, high-field, general-purpose superconducting magnet technology.​


Recently, a research team from the Institute of Electrical Engineering, Chinese Academy of Sciences, has achieved a breakthrough in the technology of large-aperture, high-field, general-purpose superconducting magnets. The team successfully developed a large-aperture, high-field, general-purpose superconducting magnet with a central magnetic field strength of 16.5 Tesla and an inner diameter of 150 mm. This achievement sets a new record for the highest magnetic field of similar large-aperture, general-purpose superconducting magnets in China to date.

Large-aperture, high-field general-purpose superconducting magnets serve as a key platform for scientific research in strong magnetic fields, providing a large-space, high-intensity magnetic field environment and demonstrating application prospects in many fields.
During the research and development process, the team adopted layered and graded current density technology and superconducting phase ratio control design methods to improve the magnetic field utilization efficiency and high field stability of the superconducting coil. They also comprehensively applied new technologies such as vacuum speed-controlled diffusion heat treatment, high-strength glass fiber composite binding and directional strengthening, densely wound coil partitioned vacuum pressure impregnation, and micron-level high-resolution online fine winding control of the superconducting coil to solve the problem of high stress and high strain faced by large-diameter high-field niobium-tin magnets in service, thereby improving the magnetic field strength at the center of the magnet.

According to authoritative third-party testing, all technical indicators of the magnet meet the design requirements and can operate stably for a long period of time. This achievement was independently developed by my country and possesses complete independent intellectual property rights.
