Tesla is making construction progress on its upcoming lithium refinery in Texas, as shown in photos taken by one drone pilot this week.

Longtime Tesla construction observer Joe Tegtmeyer shared photos of Tesla’s forthcoming lithium plant near Corpus Christi, Texas, on Monday. The photos, as posted on X, show the foundations of what will eventually be Production Line 1, with other superstructure work and the beginnings of construction on Production Line 2, as Tegtmeyer explains.

Construction on the lithium plant was well underway by August, though Tegtmeyer’s latest photos show that the site has come a long way since then. He also points out that a new electrical substation has appeared at the site, while the installation of Rotating Kiln and Cooler Set 1 equipment has mostly been completed.

Imagine never having to change a battery in a device ever again — or, in fact, a battery that could outlive you.

That’s what Betavolt, a Chinese tech company, is claiming with its newly unveiled miniature nuclear battery that it says can keep working for up to 50 years.

The Beijing-based company claims to have entered the “pilot stage” for the battery, which is smaller than a coin and will soon put it into mass production.

The idea of objects seamlessly disappearing, not just in controlled laboratory environments but also in real-world scenarios, has long captured the popular imagination. This concept epitomizes the trajectory of human civilization, from primitive camouflage techniques to the sophisticated metamaterial-based cloaks of today.

Recently, this goal was further highlighted in Science, as one of the “125 questions: exploration and discovery.” Researchers from Zhejiang University have made strides in this direction by demonstrating an intelligent aero amphibious invisibility cloak. This cloak can maintain invisibility amidst dynamic environments, neutralizing external stimuli.

Despite decades of research and the emergence of numerous invisibility cloak prototypes, achieving an aero amphibious cloak capable of manipulating electromagnetic scattering in against ever-changing landscapes remains a formidable challenge. The hurdles are multifaceted, ranging from the need for complex-amplitude tunable metasurfaces to the absence of intelligent algorithms capable of addressing inherent issues such as non-uniqueness and incomplete inputs.

Lethal drones with facial recognition, armed robots, autonomous fighter jets: we’re at the dawn of a new age of AI-powered warfare, says technologist Alexandr Wang. He explores why data will be the secret weapon in this uncharted landscape and emphasizes the need to consider national security when developing new tech — or potentially face all-out AI warfare.
