Dozens of stars show signs of hosting advanced alien civilisations

Posted by in categories: energy, space

I don’t subscribe but if you do, you’ll get more but the short summary kinda gives a general idea. Astronomers spotted 60 stars with potential Dyson sphered around them but it isn’t 100% verifiable. It could be a simpler explanation they say.


Sufficiently advanced aliens would be able to capture vast quantities of energy from their star using a massive structure called a Dyson sphere. Such a device would give off an infrared heat signature — and astronomers have just spotted 60 stars that seem to match.

ChargePoint debuts the fiercely powerful Megawatt Charging System for electric trucks

Posted by in categories: energy, information science, transportation

ChargePoint’s (NYSE: CHPT) new Megawatt Charging System for commercial electric trucks is capable of dispensing enough energy to power around 1,000 homes.

Hossein Kazemi, ChargePoint’s CTO for hardware, said, “Megawatt charging solves one-half of the electrification equation for trucking. The companies developing electric trucks can now leverage this infrastructure to test and enable their vehicles until they meet – or even exceed – the distances covered by internal combustion trucks.”

The Megawatt Charging System cable and connector will be available on ChargePoint’s Power Link 2000 stations, part of its modular Express Plus DC fast charging platform.

TMSC Announces Low-Power N4e Node, Says It’s Boosting Specialty Nodes by 50%

Posted by in categories: business, energy

It’s unclear what customers or applications might be earmarked for this node, but it’s possible it could be dedicated to IoT and other consumer devices that need to sip power. Typically, these applications use legacy nodes as it would be too expensive to use advanced processes for inexpensive devices, but TSMC is planning for the future since this effort won’t be realized until 2029 or so.

TSMC’s Dr. Kevin Zhang, senior vice president of business development and overseas Operations, says the company has already started building Greenfield, but he didn’t indicate where it’s located. He says the rapid deployment of the Greenfield fab is the first time the company has essentially skipped what we assume is a lengthy review process and put shovels in dirt already.

According to Zhang, TSMC’s move is part of its larger effort to build some resiliency into its global supply chain. That resiliency will be achieved both by building fabs outside of Taiwan and increasing capacity for nodes it thinks will be in demand in the future. Anandtech notes the company’s most advanced low-power node is currently N6e, which is a 6nm/7nm node that uses between 0.4V and 0.9V. For N4e, the company is reportedly looking to drop that all the way down to 0.4V, but it didn’t offer any additional details about its performance or attributes at the symposium.

Rubber-like Stretchable Energy Storage Device Fabricated with Laser Precision

Posted by in categories: chemistry, energy, engineering, wearables

Scientists use laser ablation technology to develop a deformable micro-supercapacitor. Professor Jin Kon Kim and Dr. Keon-Woo Kim from the Department of Chemical Engineering at Pohang University of Science and Technology (POSTECH), in collaboration with Dr. Chanwoo Yang and Researcher Seong Ju Park from the Korea Institute of Industrial Technology (KITECH), have achieved a significant breakthrough in developing a small-scale energy storage device capable of stretching, twisting, folding, and wrinkling. Their research has been published in the electronic engineering journal, npj Flexible Electronics.

The advent of wearable technology has brought with it a pressing need for energy storage solutions that can keep pace with the flexibility and stretchability of soft electronic devices.

Micro supercapacitors (MSCs) have emerged as a promising candidate for deformable energy storage, due to high-power density, rapid charging, and long cycle life.

Explosive Events in the Magnetosphere: Investigating Unusual Substorm in Earth’s Magnetotail

Posted by in category: energy

Using NASA ’s MMS mission data, SwRI explores unusual substorm events in Earth’s magnetotail to better understand magnetic reconnection and its effects on the global magnetosphere.

Southwest Research Institute (SwRI) is investigating an unusual event in the Earth’s magnetotail, the elongated extension of the planet’s magnetosphere trailing away from the Sun. SwRI scientists are examining the nature of substorms, fleeting disturbances in the magnetotail that release energy and often cause aurorae, using data from NASA’s Magnetospheric Multiscale (MMS) mission.
