The world's largest rail vehicle manufacturer has rolled out a zero-emissions train running on hydrogen fuel cells with a supercapacitor buffer. The four-car train is capable of 100 mph (160 km/h), making it the fastest hydrogen train to date.

Commissioned to create a science fiction museum in China, Zaha Hadid Architects has produced a building that wouldn't look too out of place in a sci-fi movie itself and is conceived as an expanding nebula cloud with a star at its center.

Researchers at Northwestern Polytechnical University in Xianyang, China, have demonstrated a drone that never needs to land, thanks to a remote charging system that delivers power via an adaptive, target-tracking laser on the ground.

Challenged to create one of China's largest new libraries, MVRDV riffs on its location at the confluence of two rivers to design a nature-inspired building featuring an interior that forms a "canyon of books."

Chinese automaker XPeng has updated the design of its AeroHT flying car – a luxury electric sportster with a fold-out vertical-lift octacopter system on the roof. It looks absolutely nutty, but a two-ton flying prototype indicates this is no joke.

Following an international architecture competition, a proposal from ZHA has been selected for a huge new sports complex in Hangzhou, China, which will feature significant sustainable design and be centered around an eye-catching soccer stadium.

MAD Architects' recently completed Quzhou Stadium stands out with an unusual, almost alien-like form. Likened to a halo hovering over the landscape, it's designed to encourage visitors to explore and climb over over parts of the structure.

The world's largest and, more importantly, most efficient clean compressed air energy storage system is up and running, connected to a city power grid in northern China. It'll store up to 400 MWh of energy and release enough power for 40-60,000 homes.

As the shipping industry moves to decarbonize, huge sails could be making a comeback. The China Merchant Energy Shipping company (CMES) has taken delivery of a new supertanker, whose four large sails will cut down average fuel consumption by nearly 10%.

Foster + Partners has created a new headquarters for drone manufacturer DJI. The ambitious project consists of two adjacent skyscrapers that incorporate dramatically cantilevering sections and host offices, research areas, and drone test areas.

This remarkable anti-ship weapon would run an innovative boron-powered ramjet engine that works in both air and water. Supersonic in the air and supercavitating under the water, it could strike farther and faster than any conventional torpedo.

It seems China's Chang'E-5 robotic Moon mission has discovered more than water on the lunar surface. Scientists have confirmed the discovery of a new mineral, a transparent crystal named Changesite-(Y), as well as a promising potential fusion fuel.
