On January 6, 2022, a Tesla Model S P85 (the oldest performance version) reached an impressive mileage milestone of 1,500,000 km (932,256 miles).
The car is used in Germany by Hansjörg von Gemmingen — Hornberg, who is known in the EV world for setting the highest mileage records in Tesla cars.
All-solid-state batteries are now one step closer to becoming the powerhouse of next-generation electronics, as researchers from Tokyo Tech, National Institute of Advanced Industrial Science and Technology (AIST), and Yamagata University introduce a strategy to restore their low electrical resistance. They also explore the underlying reduction mechanism, paving the way for a more fundamental understanding of the workings of all-solid-state lithium batteries.
All-solid-state lithium batteries have become the new craze in materials science and engineering as conventional lithium-ion batteries can no longer meet the standards for advanced technologies, such as electric vehicles, which demand high energy densities, fast charging, and long cycle lives. All-solid-state batteries, which use a solid electrolyte instead of a liquid electrolyte found in traditional batteries, not only meet these standards but are comparatively safer and more convenient as they have the possibility to charge in a short time.
However, the solid electrolyte comes with its own challenge. It turns out that the interface between the positive electrode and solid electrolyte shows a large electrical resistance whose origin is not well understood. Furthermore, the resistance increases when the electrode surface is exposed to air, degrading the battery capacity and performance. While several attempts have been made to lower the resistance, none have managed to bring it down to 10 Ω cm2 (ohm centimeter-squared), the reported interface resistance value when not exposed to air.
As it pursues the goal of fully autonomous driving, Tesla has bet entirely on cameras and artificial intelligence, shunning other commonly used tools such as laser detection.
Tesla Chief Executive Elon Musk has touted a system built around eight “surround” cameras that feed data into the auto’s “deep neural network,” according to Tesla’s website.
But as with so many other things involving Tesla, there is controversy.
Lithium metal batteries could store much more charge in a given space than today’s lithium-ion batteries, and the race is on to develop them for next-gen electric vehicles, electronics and other uses.
But one of the hurdles that stand in the way is a silent battle between two of the battery’s parts. The liquid between the battery electrodes, known as the electrolyte, corrodes the surface of the lithium metal anode, coating it in a thin layer of gunk called the solid-electrolyte interphase, or SEI.
Although formation of SEI is believed to be inevitable, researchers hope to stabilize and control the growth of this layer in a way that maximizes the battery’s performance. But until now they have never had a clear picture of what the SEI looks like when it’s saturated with electrolyte, as it would be in a working battery.
Aluminium Air batteries have been a thing for a while — but now a UK inventor says he’s solved one of the biggest problems with them — the toxicity of the electrolyte they’ve traditionally used.
Does this make Aluminium Air batteries viable?

Many of these systems are kept out of equilibrium because individual constituents have their own power source — ATP for cells, gas for cars. But all these extra energy sources and mismatched reactions make for a complex dynamical system beyond the reach of statistical mechanics. How can we analyze phases in such ever-changing systems?
Vitelli and his colleagues see an answer in mathematical objects called exceptional points. Generally, an exceptional point in a system is a singularity, a spot where two or more characteristic properties become indistinguishable and mathematically collapse into one. At an exceptional point, the mathematical behavior of a system differs dramatically from its behavior at nearby points, and exceptional points often describe curious phenomena in systems — like lasers — in which energy is gained and lost continuously.
Now the team has found that these exceptional points also control phase transitions in nonreciprocal systems. Exceptional points aren’t new; physicists and mathematicians have studied them for decades in a variety of settings. But they’ve never been associated so generally with this type of phase transition. “That’s what no one has thought about before, using these in the context of nonequilibrium systems,” said the physicist Cynthia Reichhardt of Los Alamos National Laboratory in New Mexico. “So you can bring all the machinery that we already have about exceptional points to study these systems.”
But how electricity will be produced? So solar powered bus will be better option.
New York governor Kathy Hochul just proposed legislation to shift the whole state to 100% electric school buses by 2035.
It’s the first flying car firm to be granted a safety certificate in Japan.
SkyDrive, the Tokyo-based startup developing a personal eVTOL aircraft, revealed its ultra-light compact flying car, the SD-03, on the show floor at the Consumer Electronics Show (CES) this week.
That makes it the first time the company has showcased its technology outside of Japan, a symbol of the global ambitions of the firm, which aims to kickstart a flying taxi service by 2025.
A flying car built for ‘door-to-door’ transportation
**“SkyDrive’s flying car is designed to vertically take off and land with superb stability and this emission-free electric vehicle enables fast and safe door-to-door transportation anywhere, including uses for emergency rescue,” the company said in its release.

If you work out of an office, you know that the coffee machine is the favorite spot in the office to hang out or have conversations at. From giving us the first cup of the day to keeping us awake for late-night meetings, that machine is a lifesaver. But just for a day, try not getting your coffee from the coffee machine. Don’t skip coffee entirely, but instead, go out to your local coffee shop that doesn’t use coffee machines or make yourself a flask at home. You will realize that hand-made coffee is inherently better than the one that is made from a machine. Not just making coffee, but highly creative jobs–like designing an outfit or writing a book–are considered best left to human creators. Many do not think that machines could emulate them. But with the takeover of artificial intelligence, this belief is steadily being challenged. Creativity and AI are together transforming many spaces that were traditionally reserved for the “artists.” In this article, we’ll be exploring these spaces and how AI is making a significant impact on them.
Creativity and AI Are Literally Changing the World When you think “creative,” the first things that come to mind are music, poetry and novels. The best works in these three areas of art have been the results of human imagination and innovation. Every significant progress in these fields has challenged traditional ways of creating art and presented a new side to human creativity. For example, there was a time when classical music was considered to be the peak of musical art, but today, we see hip-hop and K-pop taking over the world, their styles and structures very different from classical music.
