Ford says it has a ‘Skunk Works’ team trying to make lower-cost EVs

Posted by in categories: sustainability, transportation

Ford says it has a top-secret, high-powered team working to design its future electric vehicles. It’s part of a quest to compete profitably against Tesla and lower cost EV makers from China.

People in the market for an electric luxury vehicle can find plenty of options to choose from. That’s because EV technology, particularly batteries, is expensive so it’s easier for automakers to earn a profit on an Audi, Mercedes or Cadillac because people are used to paying more for those luxury car brands.

Even among mainstream auto brands, like Ford, EVs tend to cost more. Take the Mustang Mach-E, for instance, with prices starting around $45,000.

Tesla plans new world’s largest Supercharger, a glimpse at the future of charging

Posted by in categories: sustainability, transportation

Tesla is planning to build a new world’s largest Supercharger station, and it might give us a glimpse at the future of electric car charging.

There’s no doubt that Tesla has the best charging network, the Supercharger network, but it still has room to improve.

It’s not even just about improving but evolving with the different needs of the growing fleet of electric vehicles in North America.

Astrobiologists Suggest the Earth Itself May Be an Intelligent Entity

Posted by in categories: alien life, climatology, sustainability

A group of researchers have posed a fascinating — and downright mind bending — thought experiment: If a planet like Earth can be “alive,” can it also have a mind of its own?

The team published a paper exploring this question in the International Journal of Astrobiology. In it, they present the idea of “planetary intelligence,” which describes the collective knowledge and cognition of an entire planet.

Though it seems like something ripped off the screen of a Marvel movie, they believe that the concept might actually help us deal with global issues such as climate change, or even help us discover extraterrestrial life.

Researchers uncover a key link in legume plant-bacteria symbiosis

Posted by in category: futurism

Legume plants have the unique ability to interact with nitrogen-fixing bacteria in the soil, known as rhizobia. Legumes and rhizobia engage in symbiotic relations upon nitrogen starvation, allowing the plant to thrive without the need for externally supplied nitrogen.

Symbiotic nodules are formed on the root of the plant, which are readily colonized by . The cell-surface receptor SYMRK (symbiosis receptor-like kinase) is responsible for mediating the symbiotic signal from rhizobia perception to formation of the nodule. The activation mechanism of the receptor was until recently unknown.

In this study, appearing in Proceedings of the National Academy of Sciences, researchers have now identified four essential sites that act as the catalyst for the between legume plants and nitrogen-fixing bacteria. The initial steps of the symbiotic pathway at the cell surface are well characterized; however, understanding of how the signal is relayed downstream has eluded the research field for years.

LG Chem is building a $3B EV battery cathode factory — the largest in the US [Update]

Posted by in categories: energy, materials

LG Chem is building a $3 billion battery cathode factory for EVs in Tennessee – and it just inked a multi-billion dollar deal with GM.

LG Chem has secured a long-term cathode material supply contract with General Motors (GM) worth $19 billion. The contract will commence in 2026 – when the factory is expected to come online – and run until 2035.

Ultium Cells, a joint venture between LG Energy Solution and GM, will primarily use the NCMA (nickel, cobalt, manganese, aluminum) cathode materials made at LG’s Tennessee factory.

Hydrogen container ship could slash carbon emissions by 3000 tons

Posted by in categories: energy, transportation

The H2 Barge 2 is a hydrogen fuel-cell powered ship designed to transport containers on the Rhine between Rotterdam (NL) and Duisburg (DE) with zero emissions that could represent a massive reduction in carbon emissions.

Developed by Dutch shipowner Future Proof Shipping (FPS) and funded by the EU Flagships project and the Interreg ZEM Ports NS project, the H2 Barge 2 (formerly Fenny 1 and FPS Waal) was built as a conventionally powered containership before being converted to electric drive – with the 1.2 MW of power to drive the vessel’s motors coming from six PEM fuel cells, hydrogen storage, and a number of battery packs placed below deck.

Compared to its previous incarnations, the H2 Barge 2 is expected to reduce 3,000 tons of CO2 annually while sailing a comparable amount of shipping containers up and down the Rhine. And, in doing so (the company says), the vessel proves that the European river fleet can be, “fully zero emission already today.”
