The mobility rEVolution: Microgrid for EV charging, hydrogen fueling, backup power

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

Kaizen Clean Energy (KCE) and ZincFive have come together to develop an integrated distributed energy solution for EV charging, hydrogen fueling and backup power. The new solution is said to provide the lowest delivered cost for hydrogen fueling, as well as up to 2,300 kg/day of hydrogen production, which is equivalent to 38 MWh of usable energy, in a 40-foot, movable containerized solution. It can be islanded or grid-connected, with no risk of battery thermal runaway and a small volume of hydrogen stored on site. The system integrates KCE’s hydrogen generator, ZincFive’s immediate power nickel-zinc batteries, and fuel cells from Power Cell to offer customers modular, scalable economic fueling as a service. Robert Meaney, co-founder of KCE, told pv magazine that the energy input comes from methanol. He said the system is essentially the clean version of a diesel generator. It uses the ZincFive battery for immediate demand response as the methanol-to-hydrogen system ramps up to full production over the first 15 minutes. After entering full production mode, the batteries shut off and the reformer takes over the full power demand. The system is charger agnostic and can support multiple DC fast chargers at once. KCE has started accepting pre-orders and plans to deploy a 20-foot, 150 kW solution with pilot customers in the fourth quarter of 2022.

Lightyear has launched the final design of its long-range, production-ready solar car. The model, which has been renamed “Lightyear 0,” has a Worldwide Harmonized Light Vehicle Test Procedure (WLTP) range of 625 kilometers and consumption of 10.5 kWh per 100 kilometers. However, the Dutch startup claims that a theoretical range of 695 kilometers could be achieved, with a battery pack capacity of 60 kWh. “The optimized solar roof and holistic design mean that the car can drive for weeks, even months, without charging,” the company said. Lightyear is already readying its second solar electric car, which will be available by late 2024 or early 2025.

Closed-loop additive manufacturing fueled by upcycled plastic

Posted by in categories: 3D printing, chemistry, transportation

Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed an upcycling approach that adds value to discarded plastics for reuse in additive manufacturing, or 3D printing. The readily adoptable, scalable method introduces a closed-loop strategy that could globally reduce plastic waste and cut carbon emissions tied to plastic production.

Results published in Science Advances detail the simple process for upcycling a commodity plastic into a more robust material compatible with industry 3D-printing methods.

The team upgraded , or ABS, a popular thermoplastic found in everyday objects ranging from auto parts to tennis balls to LEGO blocks. ABS is a popular feedstock for fused filament fabrication, or FFF, one of the most widely used 3D-printing methods. The upcycled version boasts enhanced strength, toughness and chemical resistance, making it attractive for FFF to meet new and higher performance applications not achievable with standard ABS.

Renowned carver adopts solar power as clean-energy alternative to diesel on not-so-sunny Haida Gwaii

Posted by in categories: energy, sustainability, transportation

Over the years, Masset, B.C., master carver Jaalen Edenshaw has advocated for clean energy use on the archipelago, a region that is disconnected from B.C. Hydro’s main electricity grid and mainly reliant on diesel.

Since last October, the Haida carver has been teaming up with brother Gwaai to carve a totem pole in honour of Kaay’ahl Laanas hereditary chief Watson Price (Gaahlaay) at a workshop in Masset powered by 18 solar panels that can generate as much as 40 kWh of electricity a day — enough to fully charge a small electric car.

Edenshaw, a member of the Ts’aahl Eagle Clan, is renowned for his traditional creations, including masks, canoes, and 13-metre high red cedar totem poles that are on display in galleries around the world.

All-attosecond pump-probe spectroscopy

Posted by in categories: particle physics, transportation

An international team of researchers from the Max Born Institute in Berlin, University College London and ELI-ALPS in Szeged, Hungary, has demonstrated attosecond-pump attosecond-probe spectroscopy to study non-linear multi-photon ionization of atoms. The obtained results provide insights into one of the most fundamental processes in non-linear optics.

The detailed experimental and theoretical results have been published in Optica (“Attosecond investigation of extreme-ultraviolet multi-photon multi-electron ionization”).

Fig. 1: Two intense attosecond pulse trains (white) interact with an atom, resulting in the emission of three electrons (yellow). During this process four photons (blue) are absorbed. The probability of this process can be controlled by varying the temporal and the spatial overlap between the two attosecond pulses. (Image: Balázs Major)

Tesla Model Y with new 4680 cells shows impressive potential for faster charging

Posted by in categories: energy, sustainability, transportation

Early experiences with the new Tesla Model Y with 4,680 cells and a structural battery pack are showing some impressive potential for faster charging and better energy density.

When Tesla delivered its first made-in-Texas Model Y vehicles, we noted that it was strange that Tesla didn’t reveal any details – like specs and pricing – about the new version of the electric SUV.

A new battery design could last for an entire 100 years

Posted by in categories: sustainability, transportation

Tesla’s battery research arm based in Canada published a paper earlier this month that provides details of a battery design that could serve us for 100 years, Electrek reported.

As the world looks to reduce carbon emissions, electric transportation is one of the ways that is being touted to achieve emission targets that countries have set themselves. To ensure this can be sustainable, countries need to switch to renewable sources of power, while electric vehicle makers need to ensure that the cars themselves do not become a cause of concern.

AI’s Threats to Jobs and Human Happiness Are Very Real

Posted by in categories: economics, education, employment, existential risks, finance, robotics/AI, transportation

There’s a movement afoot to counter the dystopian and apocalyptic narratives of artificial intelligence. Some people in the field are concerned that the frequent talk of AI as an existential risk to humanity is poisoning the public against the technology and are deliberately setting out more hopeful narratives. One such effort is a book that came out last fall called AI 2041: Ten Visions for Our Future.

The book is cowritten by Kai-Fu Lee, an AI expert who leads the venture capital firm Sinovation Ventures, and Chen Qiufan, a science fiction author known for his novel Waste Tide. It has an interesting format. Each chapter starts with a science fiction story depicting some aspect of AI in society in the year 2041 (such as deepfakes, self-driving cars, and AI-enhanced education), which is followed by an analysis section by Lee that talks about the technology in question and the trends today that may lead to that envisioned future. It’s not a utopian vision, but the stories generally show humanity grappling productively with the issues raised by ever-advancing AI.

IEEE Spectrum spoke to Lee about the book, focusing on the last few chapters, which take on the big issues of job displacement, the need for new economic models, and the search for meaning and happiness in an age of abundance. Lee argues that technologists need to give serious thought to such societal impacts, instead of thinking only about the technology.

Conflux Reaches for Mass Customization with New 3D Printed Heat Exchanger Line

Posted by in category: transportation

Conflux has specialized in making heat exchangers since its inception. Previously, the company collaborated with GKN to make its technology available in Europe. We interviewed CEO Michael Fuller, including on the 3DPOD. We also saw how the startup obtainined a series A round. The next step in Conflux’s development is the mass customization of its heat exchange products.

So far, Conflux offers individually designed heat exchangers to order. Usually for F1 teams and high-end industrial applications, these high-value heat sinks have all been unique and made specifically for their applications. That’s all well and dandy, of course, but it won’t really scale.

Now. the company has developed an annular water charge air cooler (WCAC) heat exchanger. WCAC heat exchangers are all the rage in automobiles now because they can potentially be more efficient in engine cooling than plate or other heat exchangers. WCACs could potentially improve mileage, top speed, and reduce A/C consumption in passenger cars. In racing, they probably won’t focus too much on the A/C consumption, but would be very pleased with the other potential advantages.
