As technologists search for approaches to reduce our global carbon footprint and stave off the worst ravages of climate change, they are turning to an old friend—hydrogen. The potential of hydrogen fuel cells for generating power is enormous although not without issues. Published in the International Journal of Sustainable Aviation, a team from the UK and Romania […]
The Galaxy Ring is still technically under wraps, though that hasn’t meant limited previews haven’t been available. In a new FCC filing for the Galaxy Ring, Samsung has included a couple of key details and images regarding some of its ring sizes. During MWC 2024, the Galaxy Ring debuted in a very limited capacity to […]
Google’s search algorithm is perhaps the most consequential system on the internet, dictating what sites live and die and what content on the web looks like. But how exactly Google ranks websites has long been a mystery, pieced together by journalists, researchers, and people working in search engine optimization. Now, an explosive leak that purports […]
The integration of all-solid-state batteries with sulfide electrolytes is emerging as a promising electrochemical system with potential advances in energy density. The demand for thin sulfides, especially those with high flexibility, superior ionic conductivity, and strong interfacial stability, is critical. The prevailing preference for solvent-free technology is well justified due to its environmental friendliness, cost […]
Researchers at Oak Ridge National Laboratory used additive manufacturing to produce the first defect-free complex tungsten parts for use in extreme environments. The accomplishment could have positive implications for clean-energy technologies such as fusion energy. Tungsten has the highest melting point of any metal, making it ideal for fusion reactors where plasma temperatures exceed 180 […]
Nearly six months since McDonald’s opened its first CosMc’s location, the hours-long drive-thru lines have died down, but the chain is just getting started. The burger giant created the spinoff using one of its lesser-known McDonaldland mascots, CosMc, an alien who loves McDonald’s cheeseburgers. While unveiling CosMc’s at an investor event in December, McDonald’s CEO Chris Kempczinski said […]
“An engine reborn.” That’s how Japanese automaker Toyota introduced plans to cast a futuristic spin on the traditional internal combustion engine. During a three-hour presentation at a Tokyo hall Tuesday, the car manufacturer giant announced it would offer lean compact engines that also run on so-called green fuels like hydrogen and bioethanol, or get paired […]
What if a common element, rather than scarce expensive ones, was a key component in electric car batteries? A collaboration co-led by an Oregon State University chemistry researcher is hoping to spark a green battery revolution by showing that iron instead of cobalt and nickel can be used as a cathode material in lithium-ion batteries. […]
In the early 2010s, LightSquared, a multibillion-dollar startup promising to revolutionize cellular communications, declared bankruptcy. The company couldn’t figure out how to prevent its signals from interfering with those of GPS systems. Now, Penn Engineers have developed a new tool that could prevent such problems from ever happening again: an adjustable filter that can successfully […]
The design of battery technologies with increasingly longer lifespans could help to meet the growing needs of the electronics and automotive industry. Lithium (Li) batteries are the most widely used rechargeable batteries worldwide. Thus, devising strategies that can increase their longevity could be far easier than designing entirely new batteries. Li-metal batteries, batteries with a […]
The Florida Office of Energy is planning to repeal goals for utilities statewide to transition to cleaner energy, including that 100% of the state’s energy come from renewable sources by 2050. The proposal to roll back the goals was crafted by the director of the Office of Energy, Brooks Rumenik, and has been approved by […]
Owners of Spotify’s soon-to-be-bricked Car Thing device are begging the company to open source the gadgets to save some the landfill. Spotify hasn’t responded to pleas to salvage the hardware, which was originally intended to connect to car dashboards and auxiliary outlets to enable drivers to listen to and navigate Spotify. Spotify announced this week that it’s bricking all purchased […]
