Competition in the burgeoning electric vehicle market is heating up. Green car enthusiasts are already salivating at the chance to test-drive the Nissan LEAF and the Chevrolet Volt when they hit dealerships late this year. Now, it seems an underdog has stepped out from the shadows to give these big hitters a real run for their money.

At this year’s Detroit Auto Show, Chinese automaker BYD announced plans to break into the North American auto market by selling their all-electric e6 in the United States by the end of the year.

While Chevy and Nissan don’t have much to worry about in the short-term — initial rollout is currently slated for the Southern California market only — BYD has some pretty lofty goals that could spell trouble over the next few years. Specifically, BYD (which stands for “Build Your Dreams”) plans on becoming no less than the world’s largest automaker by 2025.

Electrifying transportation is an essential step towards mitigating climate change. To improve the power, efficiency and safety of electric vehicles, researchers must continue to develop better batteries.

All-solid-state lithium batteries (SSBs), which have a solid electrolyte instead of a liquid, are safer than traditional lithium-ion batteries because they are less flammable and more stable at higher temperatures. They could also have higher energy densities than lithium-ion batteries, allowing for longer lasting batteries in smaller sizes for portable electronics and other applications.

A research team led by Joshua Gallaway of Northeastern University in Boston and scientists at the Department of Energy’s (DOE) Argonne National Laboratory recently tested how the composition of thick cathodes affected electrochemical reactions in SSBs. The team used the resources of the Advanced Photon Source (APS), a DOE Office of Science user facility at Argonne. Their discoveries were published in the journal ACS Energy Letters.

It is fireproof and produces 2,500 fewer tonnes of CO2 in comparison to traditional buildings.

Singapore is now home to the largest wooden building in Asia. Named after the Greek goddess of Earth, Gaia is a 6-story structure inside the Nanyang Technological University (NTU) in Singapore. Students and the Nanyang Business School faculty will use the 43,500m square-meter facility.

As per the press release, Gaia is the eighth such project taken up by the university in its bid to install zero-energy structures to support sustainability.

A team of researchers at Duke University and their collaborators have uncovered the atomic mechanisms that make a class of compounds called argyrodites attractive candidates for both solid-state battery electrolytes and thermoelectric energy converters.

The discoveries—and the machine learning approach used to make them—could help usher in a new era of energy storage for applications such as household battery walls and fast-charging electric vehicles.

The results appeared online May 18 in the journal Nature Materials.

It’s as though Musk views in-person work as a kind of hazing ritual — he and others did it, so you have to do it too. Well, as my mom frequently said when I proposed doing something dumb because others did it, “If all your friends jumped off a bridge, would you?”

Picture this: Musk standing on the precipice of the Golden Gate Bridge, urging us all to leap into the frigid waters below simply because he took the plunge. While his bravado might be admired by some, it’s not a practical or sustainable model for the future of work. Here’s a thought: rather than Musk’s daredevil dive into the deep abyss of forced in-office work, perhaps we should consider a more measured, flexible and hybrid approach to work, one that incorporates both remote and in-person options, as I tell my clients.
