Early experiences with the new Tesla Model Y with 4,680 cells and a structural battery pack are showing some impressive potential for faster charging and better energy density.

When Tesla delivered its first made-in-Texas Model Y vehicles, we noted that it was strange that Tesla didn’t reveal any details – like specs and pricing – about the new version of the electric SUV.

Tesla’s battery research arm based in Canada published a paper earlier this month that provides details of a battery design that could serve us for 100 years, Electrek reported.

As the world looks to reduce carbon emissions, electric transportation is one of the ways that is being touted to achieve emission targets that countries have set themselves. To ensure this can be sustainable, countries need to switch to renewable sources of power, while electric vehicle makers need to ensure that the cars themselves do not become a cause of concern.

There’s a movement afoot to counter the dystopian and apocalyptic narratives of artificial intelligence. Some people in the field are concerned that the frequent talk of AI as an existential risk to humanity is poisoning the public against the technology and are deliberately setting out more hopeful narratives. One such effort is a book that came out last fall called AI 2041: Ten Visions for Our Future.

The book is cowritten by Kai-Fu Lee, an AI expert who leads the venture capital firm Sinovation Ventures, and Chen Qiufan, a science fiction author known for his novel Waste Tide. It has an interesting format. Each chapter starts with a science fiction story depicting some aspect of AI in society in the year 2041 (such as deepfakes, self-driving cars, and AI-enhanced education), which is followed by an analysis section by Lee that talks about the technology in question and the trends today that may lead to that envisioned future. It’s not a utopian vision, but the stories generally show humanity grappling productively with the issues raised by ever-advancing AI.

IEEE Spectrum spoke to Lee about the book, focusing on the last few chapters, which take on the big issues of job displacement, the need for new economic models, and the search for meaning and happiness in an age of abundance. Lee argues that technologists need to give serious thought to such societal impacts, instead of thinking only about the technology.

Dutch company Lightyear has unveiled what it claims is the world’s first production-ready solar car. The Lightyear 0 is a family sedan with 5 sq m (53.8 sq ft) of solar panels built in, capable of generating up to 70 km (44 miles) of charge-free driving a day.

Having scaled its workforce up to 500 people and hooked up deals with more than 100 suppliers, Lightyear is deadly serious about this venture and ready to start manufacturing. Its first car is this four-door fastback electric sedan, with enough onboard battery to deliver a very solid 560 km (348 miles) of freeway driving at 110 km/h (68 mph), even without the sun shining.

Conflux has specialized in making heat exchangers since its inception. Previously, the company collaborated with GKN to make its technology available in Europe. We interviewed CEO Michael Fuller, including on the 3DPOD. We also saw how the startup obtainined a series A round. The next step in Conflux’s development is the mass customization of its heat exchange products.

So far, Conflux offers individually designed heat exchangers to order. Usually for F1 teams and high-end industrial applications, these high-value heat sinks have all been unique and made specifically for their applications. That’s all well and dandy, of course, but it won’t really scale.

Now. the company has developed an annular water charge air cooler (WCAC) heat exchanger. WCAC heat exchangers are all the rage in automobiles now because they can potentially be more efficient in engine cooling than plate or other heat exchangers. WCACs could potentially improve mileage, top speed, and reduce A/C consumption in passenger cars. In racing, they probably won’t focus too much on the A/C consumption, but would be very pleased with the other potential advantages.

NASA said it was interested in UAPs from a security and safety perspective. There was no evidence UAPs are extraterrestrial in origin, NASA added. The study will begin this fall and is expected to take nine months.

The team will gather data on “events in the sky that cannot be identified as aircraft or known natural phenomena — from a scientific perspective,” the agency said.

After nine years working at NASA Jet Propulsion Laboratory, Oliver Toupet is developing cutting-edge AI algorithms that enable the self-driving zoox vehicle to understand and make decisions based on its surroundings, and to optimize trajectories to reach its destination safely and comfortably.

Learn why he says the work he’s doing at Zoox is, in some ways, more challenging than his previous work.

Electro-optic modulators, which control aspects of light in response to electrical signals, are essential for everything from sensing to metrology and telecommunications. Today, most research into these modulators is focused on applications that take place on chips or within fiber optic systems. But what about optical applications outside the wire and off the chip, like distance sensing in vehicles?

Current technologies to modulate light in free space are bulky, slow, static, or inefficient. Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), in collaboration with researchers at the department of Chemistry at the University of Washington, have developed a compact and tunable electro-optic modulator for free space applications that can modulate light at gigahertz speed.

“Our work is the first step toward a class of free-space electro-optic modulators that provide compact and efficient intensity modulation at gigahertz speed of free-space beams at telecom wavelengths,” said Federico Capasso, Robert L. Wallace Professor of Applied Physics and Vinton Hayes Senior Research Fellow in Electrical Engineering, senior author of the paper.
