“If we could see the air we fly in, we wouldn’t,” is a common saying among glider pilots. The invisible turbulent pockets that accompany soaring thermals present hazards to small aircraft, but today’s observational tools struggle to measure such wind features at high spatial resolutions over large distances. Now Yunpeng Zhang of the University of Science and Technology of China and his colleagues demonstrate how adapting a remote-sensing technology called pulsed coherent Doppler lidar (PCDL) enables long-range wind detection with submeter resolution [1].

PCDL senses wind speeds by detecting the frequency shift when a laser pulse scatters off dust particles in the air. By measuring the time taken for this scattered light to return to the detector, the technique allows wide-region profiling of wind speeds. This large-scale sampling comes at the cost of measurement precision, however. Measuring the laser’s travel time requires short-duration pulses, but short pulses transmit little total energy for a given laser power, and this energy is necessarily dispersed over a wide frequency range.

To avoid this trade-off, Zhang and his colleagues imprinted a phase-modulation pattern within each transmitted pulse using an electro-optic modulator. This pattern broke the link between pulse duration and spatial resolution, allowing a more flexible pulse duration. As a result, their setup achieved a spatial resolution of 0.9 m at a distance of 700 m (compared to a 3-m resolution at 300 m for a conventional instrument) and was able to detect the wind from an electric fan on a rooftop 329 m away.

The company also showcased other executives, which could alleviate concern that Musk has been too distracted by his other business ventures. They also talked about “meat and potato” topics like cutting costs, improving margins, and EV-charging infrastructure.

The keys to winning the EV race will come down to product appeal, software or user interface, controlling cost, and consistent execution, he said.

“And Tesla right now is one generation ahead of the other automakers,” Fields said, though rivals like Ford and Hyundai are making a lot of progress. “Tesla still has the leg-up on the competition, and I think they demonstrated that yesterday.”

‘Losing jobs to ChatGPT will never happen. The human mind is the most flexible instrument — so what you should do is, use ChatGPT as the base and then show your creativity!’ says Infosys Founder NR Narayana Murthy on whether ChatGPT is likely to take away coders’ jobs. Speaking to the press on the sidelines of the Nasscom Technology and Leadership Forum, Narayan Murthy said, “In 1977–78 there was a thing called program generators. Everybody said the youngsters will lose all jobs, it didn’t happen… The human mind is the most flexible instrument. It can adapt very well. And all that happened was people start solving bigger and bigger problems, which these program generators could not handle.” Murthy said that ChatGPT is good and one should welcome it…

AI-powered robots will be a bigger business than cars, says the business magnet.

Tesla CEO, Elon Musk, has announced the company’s latest development in AI-powered robots during Tesla’s Investor Day event. Musk said the company’s robot, known as “Optimus,” may outnumber humans in the future. This news has created a buzz in the tech community, as many are eager to see how Tesla’s latest innovation will shape the future of automation.

Modern fabrication tools such as 3D printers can make structural materials in shapes that would have been difficult or impossible using conventional tools. Meanwhile, new generative design systems can take great advantage of this flexibility to create innovative designs for parts of a new building, car, or virtually any other device.

But such “black box” automated systems often fall short of producing designs that are fully optimized for their purpose, such as providing the greatest strength in proportion to weight or minimizing the amount of material needed to support a given load. Fully manual design, on the other hand, is time-consuming and labor-intensive.

Now, researchers at MIT have found a way to achieve some of the best of both of these approaches. They used an automated design system but stopped the process periodically to allow human engineers to evaluate the work in progress and make tweaks or adjustments before letting the computer resume its design process. Introducing a few of these iterations produced results that performed better than those designed by the automated system alone, and the process was completed more quickly compared to the fully manual approach.

The photo showed the rear end of a red Tesla Model S parked in a home garage. A rather large Tesla home charger could be seen on a wall, but it did not seem to be plugged into the all-electric flagship sedan directly at all. Instead, the Model S was parked over what looked like a wireless charging pad. This promptly fueled speculations that Tesla may be looking to roll out a wireless charging system, at least for residential customers, in the future.

A wireless charging system for Teslas would be nothing short of a game-changer. The company’s Supercharger Network already changed the game thanks to its ease of use and convenience. But even manually plugging in a Tesla to a charger is less convenient than just parking over a charging pad. Of course, there are some notable disadvantages to wireless charging, such as slower charging speeds. But if Tesla can figure out a way to roll out a wireless charging system with at least a decent charging rate, the company’s vehicles would likely become even more attractive to consumers.

It took a while, but better late than never.

Tesla has now begun to provide non-Tesla electric vehicle owners in the U.S. with access to some Supercharger stations and has also explained how the stations work, Electrek.

Electric-car maker Tesla Inc. plans to build a manufacturing plant in the northern Mexican industrial hub of Monterrey, President Andrés Manuel López Obrador said Tuesday.

Mr. López Obrador, who spoke several times in recent days with Tesla Chief Executive Elon Musk, added at his morning press conference that details of the investment would be made known Wednesday.
