However, the IMO warned that lava may still continue to flow beneath this solidified crust toward the protective barriers near the Blue Lagoon, though its advance has significantly slowed.
Over the last week, the constant flow of the lava has gradually engulfed the tourist destination’s car park and continues to grow in size.
The Blue Lagoon was evacuated ahead of the lava’s arrival, as were 50 homes in the town of Grindavík, which is home to 3,800 residents.
CycloTech’s all-electric flying vehicle is capable of controlled descents even in stormy weather with motors similar to those used for tug boats.
In the simplest terms, nearly every modern car on the planet uses disk brakes: a rotor attached to a hub with a caliper with brake pads fixed to the control arm at each wheel. The driver presses the brake pedal and hydraulic fluid is pushed down the brake lines into the caliper, expanding the pistons and pushing the brake pads against the rotor, slowing down the rotation of the rotor connected to the hub, thus slowing down the wheel.
There are other systems, like drum brakes, air brakes, band brakes, the Flintstones method, et cetera, that have also been around since the dawn of the automotive industry. The concept almost always remains the same: using friction to slow down. And so it doesn’t go unsaid, yes, there are compression brake systems as well, but that’s entirely different.
Mercedes-Benz has put a new spin on an age-old concept with what it calls “in-drive brakes” for electric vehicles. The system being developed at the company’s research and development department in Sindelfingen, Germany, integrates the brakes right into the drivetrain, in an arrangement that works very much like a transmission brake. It resembles clutch plates – but with a unique twist.
On a cool morning this summer, I visited a former shopping mall in Mountain View, California, that is now a Google office building. On my way inside, I passed a small museum of the company’s past “moonshots,” including Waymo’s first self-driving cars. Upstairs, Jonathan Tompson and Danny Driess, research scientists in Google DeepMind’s robotics division, stood in the center of what looked like a factory floor, with wires everywhere.
At a couple of dozen stations, operators leaned over tabletops, engaged in various kinds of handicraft. They were not using their own hands—instead, they were puppeteering pairs of metallic robotic arms. The setup, known as ALOHA, “a low-cost open-source hardware system for bimanual teleoperation,” was once Zhao’s Ph.D. project at Stanford. At the end of each arm was a claw that rotated on a wrist joint; it moved like the head of a velociraptor, with a slightly stiff grace. One woman was using her robotic arms to carefully lower a necklace into the open drawer of a jewelry case. Behind her, another woman prized apart the seal on a ziplock bag, and nearby a young man swooped his hands forward as his robotic arms folded a child’s shirt. It was close, careful work, and the room was quiet except for the wheeze of mechanical joints opening and closing. “It’s quite surprising what you can and can’t do with parallel jaw grippers,” Tompson said, as he offered me a seat at an empty station. “I’ll show you how to get started.”
Using the European XFEL free-electron laser, researchers demonstrate terawatt-scale, attosecond hard X-ray pulses. Ten pulse trains per second, each containing hundreds of pulses at megahertz repetition rates, are achieved. Such short and intense pulses at high repetition rate enable unprecedented damage-free X-ray measurements with attosecond temporal resolution.
Discovery enables manufacturing of ultrathin solar panels, advanced optoelectronics.
By creating a new way for light and matter to interact, researchers at the University of California, Irvine have enabled the manufacturing of ultrathin silicon solar cells that could help spread the energy-converting technology to a vast range of applications, including thermoelectric clothing and onboard vehicle and device charging.
The development, subject of a paper recently published as the cover story in the journal ACS Nano, hinges on the UC Irvine researchers’ conversion of pure silicon from an indirect to a direct bandgap semiconductor through the way it interacts with light.
At some point in the early 1900s, cars started showing up among all the horses in Austin. It must have been a strange time, fraught with concerns about how vehicles and horses would share the streets.
Somehow, we got through it — although, occasionally, you can still spot a horse downtown.
But a new dynamic is taking shape now. While autonomous vehicles are nothing new for Austin — they’ve been tested here for nearly a decade — many people are still being caught off guard when a car with no one in it cruises by.
The automaker built a demonstration production line to figure out how to make affordable, high-density solid-state batteries for EVs and everything else.
The biggest battleground in the robotaxi race may be winning public trust.
Autonomous vehicles are already clocking up millions of miles on public roads, but they face an uphill battle to convince people to climb in to enjoy the ride.
A few weeks ago, I took a tour of San Francisco in one of Waymo’s self-driving cars. As we drove around the city, one thing that struck me was how comfortable people had become with not seeing a driver. Not only were there multiple driverless vehicles on any given street at any given time, but tourists no longer had their mouths agape as one drove by. The technology has become a familiar sight.
That will get battery costs below the point needed to achieve EV price parity with gasoline vehicles.
