Intel introduces approach to Boost Power Efficiency, Reliability of Packaged Chiplet Ecosystems

The integration of electronic chips in commercial devices has significantly evolved over the past decades, with engineers devising various integration strategies and solutions. Initially, computers contained a central processor or central processing unit (CPU), connected to memory units and other components via traditional communication pathways, known as front-side-bus (FSB) interfaces.

Technological advances, however, have enabled the development of new integrated circuit (IC) architectures relying on multiple chiplets and more sophisticated electronic components. Intel Corporation played a crucial role in these developments, by introducing new architectures and specifications for the design of systems with multiple packaged chiplets.

Researchers at Intel Corporation Santa Clara recently outlined a new vision for further boosting the performance of systems developed following universal chiplet interconnect express (UCIe), a specification to standardize the connections between multi-function chiplets in modern System-in-Package (SiP). Their proposed approach, presented in a paper in Nature Electronics, entails reducing the frequency in these circuits to boost their power efficiency and performance.

Kia to begin EV9 production in the US by May, expects $7,500 EV tax credit eligibility by 2025

Kia’s first three-row electric SUV is off to a good start. However, Kia will accelerate EV9 momentum with plans to begin US production by May. Kia expects the EV9 will qualify for the full $7,500 EV tax credit by early next year.

After launching the EV9 in the US late last year, Kia has handed over 3,839 models in the US. Starting under $55,000, Kia calls its electric family move an “industry wake-up call.”

Despite the strong start, Kia expects the momentum to pick up. Kia currently builds the EV9 in Korea but expects to move production to the US by the end of May.

Fuel-cell train travels more than 1,700 miles on one tank of hydrogen

A hydrogen fuel-cell passenger train developed by Swiss rail vehicle maker Stadler Rail has achieved a new Guinness World Record, traveling for almost two days around the clock for a distance of 1,741.7 miles.

Efforts to clean up dirty trains are already well underway, with heavy investment in electrifying networks around the world as well as rolling out battery-electric locomotives such as the FLXDrive, the Blues train and the Flirt Akku.

That last example is made by Stadler Rail AG, and managed to achieve a Guinness World Record in 2021 for the longest per-charge battery-only journey of 224 km (~140 miles), on a route between Berlin and Warnemünde during a freezing local winter – not bad for a train that was designed with an operational per-charge range of 80 km.

Tesla Supercharger NACS access clarified by TSLA Exec

Tesla executive Rohan Patel clarified some facts about Supercharger NACS access for non-Tesla vehicles like Rivian and Ford.

Patel—Tesla’s Vice President of Public Policy and Business Development—recently replied to a question from Teslavangelist, who questioned the number of Supercharger stalls non-Tesla owners actually had access to with NACS connectors.

Tesla recently opened the Supercharger Network to Ford and Rivian electric vehicles (EVs) through its NACS connecter. Both automakers claim that NACS connectors provide Ford and Rivian owners access to over 15,000 Tesla Supercharger locations. Teslavangelist pointed out that non-Tesla EV owners only have access to V3 and V4 Superchargers, doubting they have access to 15,000 Supercharger stalls.

Dutch hyperloop center aims to advance futuristic transport technology

VEENDAM, Netherlands (AP) — A 420-meter (quarter-mile) white steel tube running alongside a railway line in the windswept northern Netherlands could usher in a new era in the transportation of people and freight.

The tube is the heart of the new European Hyperloop Center that opens Tuesday and will be a proving ground in coming years for developers of the evolving technology.

Hyperloop, once trumpeted by Elon Musk, involves capsules floating on magnetic fields zipping at speeds of arund 700 kph (435 mph) through low-pressure tubes. Its advocates tout it as far more efficient than short haul flights, high-speed rail and freight trucks.

World’s first mass-produced 900V EV drive system rolls out with 5 minute fast charge

The first mass-produced 900V drive system rolled off the production line Wednesday. Chinese EV maker NIO’s (NIO) “Thunder” 900V electric drive system (EDS) can add over 150 miles (255 km) with five-minute fast charge.

NIO announced the milestone Wednesday after building its one-millionth EDS. NIO’s Porsche-rivaling ET9 premium EV will be the first to feature the new tech.

The ET9 was unveiled in December aimed at “the new generation of high-end business users.” NIO packed the luxury EV with its latest tech for a “perfect package of flagship-style exterior, spacious interior, immersive experience, efficient recharging.”

Swiss hydrogen-powered train sets 1741-mile record for nonstop travel

The attempt began on the evening of March 20, and GWR officials were present at the test site. Engineers from Stadler drove the train in shifts over the night and the following day. When the train stopped at 5:23 pm on March 22, it had traveled 1,741.7 miles (2,803 km) over 46 hours, all on a single fuel tank.

This is six times the distance of FLIRT H2’s advertised range – 285 miles (460 km). However, it is unlikely to be replicated in real-life scenarios since the train did not stop and start multiple times during the record attempt, nor did it travel on different inclines. Nevertheless, it showcased the ability of hydrogen fuel as a potential power source for trains.
