Mercedes-Benz Backs Off Plan To Only Sell EVs By 2030

In its fourth quarter earnings statement on Thursday, Mercedes-Benz said it is backing off its plan to only sell electric vehicles after 2030. Instead, the company said it "only expects 50 percent of its sales to be all-electric -- a significant drop from the once rosier outlook," reports The Verge. "Gas and hybrid vehicles will remain a part of the company's future for years to come." From the report: "Customers and market conditions will set the pace of the transformation," Mercedes said in its report. "The company plans to be in a position to cater to different customer needs, whether it's an all-electric drivetrain or an electrified combustion engine, until well into the 2030s." Not even in Europe, where EV sales growth outpaces North America's, does Mercedes expect to transition to EV-only sales anytime soon, the company's CEO Ola Kallenius told Reuters. "It's not going to be 100% in 2030, obviously... from the whole European market, but probably from the Mercedes side as well," he said. In 2021, Mercedes was a lot more bullish about plug-in powertrains, saying that by 2030 it would only sell EVs and completely phase out gas-powered vehicles.

Switzerland Calls On UN To Explore Possibility of Solar Geoengineering

Switzerland is advocating for a United Nations expert group to explore the merits of solar geoengineering. The proposal seeks to ensure multilateral oversight of solar radiation modification (SRM) research, amidst concerns over its potential implications for food supply, biodiversity, and global inequalities. The Guardian reports: The Swiss proposal, submitted to the United Nations environment assembly that begins next week in Nairobi, focuses on solar radiation modification (SRM). This is a technique that aims to mimic the effect of a large volcanic eruption by filling the atmosphere with sulphur dioxide particles that reflect part of the sun's heat and light back into space. Supporters of the proposal, including the United Nations environment program (UNEP), argue that research is necessary to ensure multilateral oversight of emerging planet-altering technologies, which might otherwise be developed and tested in isolation by powerful governments or billionaire individuals. Critics, however, argue that such a discussion would threaten the current de-facto ban on geoengineering, and lead down a "slippery slope" towards legitimization, mainstreaming and eventual deployment. Felix Wertli, the Swiss ambassador for the environment, said his country's goal in submitting the proposal was to ensure all governments and relevant stakeholders "are informed about SRM technologies, in particular about possible risks and cross-border effects." He said the intention was not to promote or enable solar geoengineering but to inform governments, especially those in developing countries, about what is happening. The executive director of the UNEP, Inger Andersen, stressed the importance of "a global conversation on SRM" in her opening address to delegates at a preliminary gathering in Nairobi. She and her colleagues emphasized the move was a precautionary one rather than an endorsement of the technology.

Facial-Recognition System Passes Test On Michelangelo's David

An anonymous reader quotes a report from Ars Technica: Facial recognition is a common feature for unlocking smartphones and gaming systems, among other uses. But the technology currently relies upon bulky projectors and lenses, hindering its broader application. Scientists have now developed a new facial recognition system that employs flatter, simpler optics that also require less energy, according to a recent paper published in the journal Nano Letters. The team tested their prototype system with a 3D replica of Michelangelo's famous David sculpture and found it recognized the face as well as existing smartphone facial recognition can. [...] Wen-Chen Hsu, of National Yang Ming Chiao Tung University and the Hon Hai Research Institute in Taiwan, and colleagues turned to ultrathin optical components known as metasurfaces for a potential solution. These metasurfaces can replace bulkier components for modulating light and have proven popular for depth sensors, endoscopes, tomography. and augmented reality systems, among other emerging applications. Hsu et al. built their own depth-sensing facial recognition system incorporating a metasurface hologram in place of the diffractive optical element. They replaced the standard vertical-cavity surface-emitting laser (VCSEL) with a photonic crystal surface-emitting laser (PCSEL). (The structure of photonic crystals is the mechanism behind the bright iridescent colors in butterfly wings or beetle shells.) The PCSEL can generate its own highly collimated light beam, so there was no need for the bulky light guide or collimation lenses used in VCSEL-based dot projector systems. The team tested their new system on a replica bust of David, and it worked as well as existing smartphone facial recognition, based on comparing the infrared dot patterns to online photos of the statue. They found that their system generated nearly one and a half times more infrared dots (some 45,700) than the standard commercial technology from a device that is 233 times smaller in terms of surface area than the standard dot projector. "It is a compact and cost-effective system, that can be integrated into a single chip using the flip-chip process of PCSEL," the authors wrote. Additionally, "The metasurface enables the generation of customizable and versatile light patterns, expanding the system's applicability." It's more energy-efficient to boot.
