Toyota CEO: “Our Ammonia Engine Is the End of EV’s”

In a world that seems inexorably drawn towards an all-electric future, Toyota has consistently taken a different road. The Japanese automaker remains skeptical about an exclusive reliance on electric vehicles (EVs). While it’s true that Toyota has some exciting EVs in the pipeline for the upcoming year, they are also actively exploring alternative energy sources. However, a recent development could potentially turn the tables on the EV revolution — an ammonia-powered engine for passenger vehicles.

Durable, inexpensive electrocatalyst generates clean hydrogen and oxygen from water

A new electrocatalyst made of nickel (Ni), iron (Fe) and silicon (Si) that decreases the amount of energy required to synthesize H2 from water has been manufactured in a simple and cost-effective way, increasing the practicality of H2 as a clean and renewable energy of the future.

Hydrogen is a highly combustible gas that can help the world achieve its clean energy goals if manufactured in an environmentally responsible way. The primary hurdle to creating hydrogen gas from water is the large amount of energy required for the electrolysis of water, or splitting into hydrogen gas (H2) and oxygen (O2).

Most H2 produced today is derived from fossil fuels, which contributes to global warming. Manufacturing H2 from water through the (HER) requires the use of a catalyst, or agent that lowers the amount of energy required for a chemical reaction. Until recently, these catalysts were made up of , like platinum, reducing the cost-efficiency and practicality of clean hydrogen production.

Using the world’s three most powerful particle accelerators to reveal the space-time geometry of quark matter

Physicists from the Eötvös Loránd University (ELTE) have been conducting research on the matter constituting the atomic nucleus utilizing the world’s three most powerful particle accelerators. Their focus has been on mapping the “primordial soup” that filled the universe in the first millionth of a second following its inception.

Intriguingly, their measurements showed that the movement of observed particles bears resemblance to the search for prey of marine predators, the patterns of climate change, and the fluctuations of stock market.

In the immediate aftermath of the Big Bang, temperatures were so extreme that atomic nuclei could not exists, nor could nucleons, their building blocks. Hence, in this first instance the universe was filled with a “” of quarks and gluons.

AI: A tool for climate resilience and farming

AI probably won’t replace the need for humans in the climate change fight, but it could make their work faster and more effective.

But a Silicon Valley startup called ClimateAi uses artificial intelligence to help farmers cope with the warming temperatures. The startup has created a platform to assess any place’s climate, water, and soil conditions and forecast its suitability for growing crops in the next 20 years.

Tesla exec shares Cybertruck first delivery event details

Tesla Investor Relations (IR) Head Martin Viecha has provided some key details about the upcoming Cybertruck first delivery event, which is scheduled to be held at Gigafactory Texas this Thursday, November 30, 2023. Contrary to other Tesla events like the Cyber Rodeo, the Cybertruck’s first deliveries will be starting notably earlier.

As noted by Martin Viecha, the Tesla Cybertruck delivery event will be starting at 1 p.m. CT (11 a.m. PST). Expectations are high that Tesla will be live-streaming the event, though the executive has not provided information about when the livestream for the occasion will go live.

“The Cybertruck delivery event starts at around 1 p.m. CT on Thursday, in case someone’s unsure. I’ve noticed that few people thought it’s an evening event,” Viecha clarified on X, the social media platform formerly known as Twitter.

New design for a rechargeable hydrogen-chlorine battery in a wide temperature range

A research team led by Prof. Chen Wei from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) designed a rechargeable hydrogen-chlorine (H2-Cl2) battery that can operate in temperatures ranging from −70°C to 40°C. The study was published in Journal of the American Chemical Society as the cover article.

Hydrogen fuel cells are a promising technology valuable for their sustainability and the abundance of hydrogen, among which H2-Cl2 fuel cells stand out due to fast electrochemical kinetics, high redox potential and high specific capacity of Cl2/Cl- redox couple. However, the volatile chlorine gas cannot be retained during the charging process, resulting in poor Coulombic efficiency (CE) and reversibility. There is an urgent need to develop aqueous chlorine batteries with and applicability at different temperatures.

The research team first discovered that due to the lack of binding sites with strong affinity to Cl2, traditional adsorptive cathodes have difficulty immobilizing Cl2, causing low reversibility. To tackle this problem, the team designed a hierarchically porous carbon composed of highly micro-/mesoporous carbon (HPC) and macroporous carbon felt (CF), effectively confining the Cl2 on the cathode and improving the reversibility.

Utility Personal Transporter is set to be the smartphone of EVs

Remember back before smartphones existed, when you had to buy a separate cell phone, camera, music player, calculator and calendar? Well, the Utility Personal Transporter may one day do for electric vehicles what smartphones did for gadgets.

Currently in functional prototype form, the Utility Personal Transporter (UPT) is being developed by Canadian electric mobility company Envo Drive Systems. In a nutshell, it’s a four-wheel-drive electric platform that can be adapted to serve multiple purposes.

Envo unveiled the vehicle to the media last Friday, at an event that also showcased the new Veemo velomobile. That said, the UPT more closely resembles one of the company’s longer-established products, the e-ATV.
