Germany is No 1 in Europe for EV production, No 2 in the world

Germany’s automakers manufactured around 1.27 million BEVs and PHEVs in 2023, putting it at No. 2 behind China, but 2024 will be bumpy.

The German automotive industry association VDA says that 995,000 purely electric vehicles rolled off German assembly lines in 2023.

China dominates global EV production, but most of its cars are sold domestically. By contrast, 76% of German EVs are sold abroad. The US holds the spot for the world’s third-largest EV maker. And Germany, the home of key automakers such as Volkswagen, BMW, and Mercedes-Benz, leads Europe with more EVs produced than second-placed Spain (256,000) and France (225,000) combined.

3D-printed mini-actuators can move small soft robots, lock them into new shapes

If users wish to “freeze” the soft robot’s shape, they can apply moderate heat (64°C, or 147°F), and then let the robot cool briefly. This prevents the soft robot from reverting to its original shape, even after the liquid in the microfluidic channels is pumped out. If users want to return the soft robot to its original shape, they simply apply the heat again after pumping out the liquid, and the robot relaxes to its original configuration.

“A key factor here is fine-tuning the thickness of the shape memory layer relative to the layer that contains the microfluidic channels,” says Yinding Chi, co-lead author of the paper and a former Ph.D. student at NC State. “You need the shape memory layer to be thin enough to bend when the actuator’s pressure is applied, but thick enough to get the soft robot to retain its shape even after the pressure is removed.”

To demonstrate the technique, the researchers created a soft robot “,” capable of picking up small objects. The researchers applied hydraulic pressure, causing the gripper to pinch closed on an object. By applying heat, the researchers were able to fix the gripper in its “closed” position, even after releasing pressure from the hydraulic actuator.

World’s heaviest soaring bird inspires wind power design

When placed at the tip of a turbine blade, the c-shaped “winglet” inspired by the condor reduces drag, potentially increasing the turbine’s efficiency by up to 10% in optimal conditions, according to a study published in the journal Energy.

The wings of soaring birds have also been adapted for use in commercial and military aircraft around the world to increase their lift, says co-author Brian Fleck, a professor of mechanical engineering and expert in fluid dynamics.

“We used to have airplanes with straight wings,” says Fleck. “Now we see them with the tips curled up, and there’s a reason for that.”

Former OpenAI Director Warns There Are Bad Things AI Can Do Besides Kill You

There’s a lot of other ways that AI could really take things in a bad direction.

One of the OpenAI directors who worked to oust CEO Sam Altman is issuing some stark warnings about the future of unchecked artificial intelligence.

In an interview during Axios’ AI+ summit, former OpenAI board member Helen Toner suggested that the risks AI poses to humanity aren’t just worst-case scenarios from science fiction.

“I just think sometimes people hear the phrase ‘existential risk’ and they just think Skynet, and robots shooting humans,” Toner said, referencing the evil AI technology from the “Terminator” films that’s often used as a metaphor for worst-case-scenario AI predictions.

New plasma escape mechanism could protect fusion vessels from excessive heat

By Rachel Kremen, Princeton Plasma Physics Laboratory

The furious exhaust heat generated by a fusing plasma in a commercial-scale reactor may not be as damaging to the vessel’s innards as once thought, according to researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), Oak Ridge National Laboratory and the ITER Organization (ITER).

Apple Teases Immersive ‘3D’ Photos With visionOS 2, Wider Vision Pro Rollout

Apple today teased the first update for its mixed-reality headset, visionOS 2, which includes AI-powered spatial photos and videos for the Vision Pro to give them a more immersive feel.

As part of its WWDC presentation, Apple also unveiled a special “spatial” lens for Canon cameras designed to capture moments viewable on the Vision Pro, as well as a partnership with cinema camera company Blackmagic Design.
