An integrated plant that will remove 50,000 tonnes of carbon dioxide every year and create new freshwater from salty seawater is planned in the Daesan Industrial Complex in South Korea. When ready, this will be the world’s first such facility.

As countries work on their promises to go carbon neutral in a few decades, there is a strong push for innovative approaches that capture and utilize carbon. Carbon capture facilities work onsite to help reduce the release of carbon into the atmosphere. In contrast, direct air capture (DAC) technology focuses on removing the released carbon dioxide from the atmosphere.

CATL has unveiled Tener, a new large scale energy storage system to compete with Tesla Megapack.

The system has almost twice the energy capacity of the Megapack, and CATL claims zero degradation after 5 years.

Tesla Megapack is the poster boy of large-scale energy storage.

The energy storage device has been used in most of the world’s largest energy storage projects, and it is expanding fast.

Physicists have observed a novel quantum effect termed “hybrid topology” in a crystalline material. This finding opens up a new range of possibilities for the development of efficient materials and technologies for next-generation quantum science and engineering.

The finding, published on April 10th in the journal Natur e, came when Princeton scientists discovered that an elemental solid crystal made of arsenic (As) atoms hosts a never-before-observed form of topological quantum behavior. They were able to explore and image this novel quantum state using a scanning tunneling microscope (STM) and photoemission spectroscopy, the latter a technique used to determine the relative energy of electrons in molecules and atoms.

This state combines, or “hybridizes,” two forms of topological quantum behavior—edge states and surface states, which are two types of quantum two-dimensional electron systems. These have been observed in previous experiments, but never simultaneously in the same material where they mix to form a new state of matter.

SpaceX has shared dramatic slow-motion footage showing a Raptor engine powering down at the end of a recent test fire.

“Shutdown of a Raptor vacuum engine in slow motion,” SpaceX said in a message accompanying the video (below). It added that the engine’s nozzle “is sized for use by Starship in the Earth’s upper atmosphere and outer space, so operation at sea level and low chamber pressures results in flow separation creating visible rings in the exhaust.”

After months of leaks, OpenAI has apparently fired two researchers who are said to be linked to company secrets going public.

As The Information reports based on insider knowledge, the firm has fired researchers Leopold Aschenbrenner — said to be a close ally of embattled cofounder Ilya Sutskever — and Pavel Izmailov.

Both men had worked on OpenAI’s safety team, per the report, though most recently, Aschenbrenner had been working on its so-called “superalignment” efforts while Izmailov was tasked with researching AI reasoning. We’ve reached out to OpenAI and Microsoft, its major investor, for further context.

Tesla has revealed some of its humanoid robot technology through filings for several new patents related to its Optimus robot program.

A few months ago, Tesla unveiled “Optimus Gen 2”, a new generation of its humanoid robot that should be able to take over repetitive tasks from humans.

The new prototype showed a lot of improvements compared to previously underwhelming versions of the robot, and it gave some credibility to the project.
