Bridgestone’s airless tires near production, testing to begin soon

Posted by in categories: sustainability, transportation

Its concept is maintenance-free, recyclable, and offers low rolling resistance.

The concept of airless tires is getting closer to production, with Bridgestone’s version going in for testing in February 2023. The firm’s product is based on its “Air Free Concept,” a technology that eliminates the need for tires to be inflated with air to support the weight using a unique structure of spokes stretching along the inner sides of tires.

Microstructure and defect engineering improves performance of lithium-ion batteries

Posted by in categories: energy, engineering, sustainability, transportation

A new North Carolina State University study, performed in collaboration with battery testing researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory, shows that extremely short pulses from a high-powered laser can cause tiny defects in lithium-ion battery materials—defects that can enhance battery performance.

The technique, called nanosecond pulsed laser annealing, lasts for only 100 nanoseconds and is generated by the same type of laser used in modern-day eye surgeries. Researchers tested the technique on graphite, a material widely used in lithium-ion battery anodes, or positive electrodes. They tested the technique in batches of 10 pulses and 80 pulses and compared the differences in current capacity; power is calculated by multiplying voltage by current.

Lithium-ion batteries are widely used in portable electronic devices and electric cars. With further improvements, these batteries could have a major impact on transportation and as storage devices for renewable energy sources like wind and solar.

Airless, Puncture-Proof Tires Created By GM and Michelin

Posted by in category: transportation

Could a tire be puncture-free, better for the environment, and minimize danger on roads? It sounds almost too good to be true. Back in 2017, General Motors (GM) and Michelin teamed up to execute exactly that, creating an airless tire.

The tire, called ‘Unique Puncture-proof Tire System’ or Uptis in short, is due to launch in 2024. The aim is for a complete reshuffle of conventional wheels and tires so that they are fully replaced as an assembly unit for passenger cars.

Samsung hires former Qualcomm VP who is a semiconductor expert

Posted by in categories: mobile phones, robotics/AI, transportation

Samsung has been on a hiring spree of top executives from reputed companies in the last few months. About a week ago, we reported that Samsung had hired two former Ericsson executives to its Samsung Networks team. Last December, Samsung roped in an ex-Mercedes designer, Hubert H. Lee, to lead its smartphone design team. Now, Samsung has now hired former Qualcomm Vice President Benny Katibian.

Benny previously worked for Qualcomm as the Vice President of the company’s engineering division. After joining Samsung, Benny will serve as the head of the Samsung Austin Research Center (SARC) and the Advanced Computing Lab (ACL), which are the core R&D centers of Samsung Electronics USA, as per Business Korea.

According to reports, Benny Katibian is an expert in semiconductors and was in charge of self-driving systems, including ADAS (Advanced Driving Assistance Systems) at Qualcomm. Later, he also served as the COO of the North American Cooperation in Xiaopeng, a Chinese electric car company. He also worked as the head of the development of self-driving chips.

Netanyahu aims to fill West Bank with high-speed tunnels, in vision laid out

Posted by in categories: Elon Musk, engineering, transportation

Prime Minister Benjamin Netanyahu has proposed building a network of underground highway systems across the West Bank to enable the maintenance of territorial contiguity for both Israeli settlements and Palestinian towns, The Times of Israel’s sister site, Zman Yisrael, reported Saturday.

Netanyahu is aiming for high-speed tunnels routes designed ostensibly to address the problems of traffic jams and congestion, per the vision of the billionaire Elon Musk, and his engineering firm Boring Company.

Netanyahu presented his plans during a conversation Friday with French investors in Paris at the hotel where he spent the weekend.

San Francisco Tries To Slow Down Waymo And Cruise Robotaxi Expansion. Should They Go Elsewhere?

Posted by in categories: government, robotics/AI, transportation

In the world of self-driving, the strong leaders are now Google/Alphabet’s Waymo, and GM’s Cruise. Both are headquartered in the San Francisco Bay Area, and both have thus been keen to deploy in the city of San Francisco itself. No wonder, it’s their hometown. Driving it is a challenge but an important one to handle. On the other hand, it doesn’t snow, though it faces fog. It’s a city that already has many people who don’t own cars, and it was the birthplace of ride-hail, first with the now-defunct Sidecar, then Lyft and Uber. It makes a lot of sense that they both want to be there.

Even so, the city of San Francisco and it’s agencies have not been too happy with the pilot deployments of these companies and recently wrote letters hoping to slow them down. This article examines the conflict between the companies and their city, considering not just the particular points of contention, but also what sort of relationship makes sense here and how to resolve conflicts going forward.

San Francisco doesn’t have the authority to regulate driving. That’s the California DMV. Ride services are under the authority of the California Public Utilities Commission. The federal government regulates the making, importing and selling of vehicles and keeping them safe.

Fully autonomous passenger planes are inching closer to takeoff

Posted by in categories: robotics/AI, transportation

The world’s biggest commercial aircraft makers seem increasingly convinced that autonomous passenger flight is a question of when, not if.

Where it stands: Flying today’s high-tech passenger jets is often a matter of setting up and overseeing their autopilot and other automated systems — but we’re not yet at a point where computer systems can entirely replace human pilots.

Driving the news: “Autonomy is going to come to all of the airplanes eventually,” Boeing CEO Dave Calhoun told Bloomberg TV at an event this week marking the delivery of the last commercial 747.
