Dahn, a world-renowned battery scientist and NSERC/Tesla Canada Chair, presented the exciting news during his keynote presentation (titled: More than a million miles and a century of life) at the international battery seminar (IBS) held 28–31 March 2022 in Orlando, Florida.

The term “Million Mile” battery first came to life after Dahn’s 2019 open access publication in Journal of The Electrochemical Society (JES) stating “we conclude that cells of this type should be able to power an electric vehicle for over 1.6 million kilometers (1 million miles) and last at least two decades in grid storage”.

You heard that right, it’s time to cool down the solar farms a bit.

It’s a common belief that a solar panel produces more energy on receiving more sunlight but that’s not always true. In fact, a report from the World Economic Forum state that photovoltaic cells on a solar panel (that trap sunlight and convert it into electricity) may start producing less energy if they get overheated.

A new study conducted by a team of researchers from the University of Utah (UU), National Renewable Energy Laboratory (NREL), and Portland State University (PSU), sheds more light on this rarely discussed aspect of solar panels. It mentions that the efficiency of a solar plant goes down by 0.5 percent.

Many solar panel manufacturers suggest that the ideal temperature for commercially used solar panels ranges between 15°C and 35°C, and the PV cells achieve the highest energy efficiency at 25°C. So, if a solar plant experiences a temperature around 50°C, it may suffer energy losses of up to 12 percent.

A key light-activated nanomaterial for the hydrogen economy has been engineered by researchers at Rice University. Using only inexpensive raw materials, scientists created a scalable catalyst that needs only the power of light to convert ammonia into clean-burning hydrogen fuel.

“This discovery paves the way for sustainable, low-cost hydrogen that could be produced locally rather than in massive centralized plants.” —

The research, which was published on November 24 in the journal Science, was conducted by a team from Rice’s Laboratory for Nanophotonics, Syzygy Plasmonics Inc., and Princeton University.

Tesla Semi carried 81,000 pounds for 500 miles on a single charge.

Just a few days before Tesla begins shipping the truck, Elon Musk has verified that Tesla Semi, the company’s Class 8 semi-truck, has successfully completed a crucial voyage.

Although there is no reason to question the outcome, it would be interesting to learn more about speed and energy usage. We are pretty interested in seeing some impartial vehicle tests.

Elon Musk recently tweeted that a Tesla Semi completed an 800-kilometer (500-mile) drive carrying 81,000 pounds (36,740 kilograms), which is nearly 100 percent of its Gross Combination Weight (GCW) of 82,000 pounds.

Elon GOAT Token’s efforts to deliver the statue landed the company on Twitter’s U.S. trending page. Musk purchased the social network last month, causing an upheaval with mass layoffs, departed advertisers and potential changes to the process of obtaining a Twitter Blue check mark.

Costing a total of $600,000, according to Elon GOAT Token, the Musk sculpture is a nod to the billionaire’s fame — a rocket representing SpaceX, the spacecraft company Musk founded; and the literal goat, a word that is also used as an acronym for the phrase “Greatest Of All Time.”

Tesla has plans to ramp its electric vehicle production by a notable degree in the coming years, and with the company’s constant innovations, it would need to secure a lot of resources, from battery raw materials to computer chips.

In this light, reports have emerged suggesting that Tesla has established a semiconductor joint venture in Jinan of eastern China’s Shandong Province. The joint venture is intended to supply automotive chip and electronics solutions. Tesla partnered with Swiss automotive semiconductor company Annex for the joint venture, which boasts a registered capital of $150 million.

As per a report from Chinese tech publication ijiwei, Tesla holds a 5% equity in the company for now, while Annex holds a 55% stake, and the Jinan Zurich Annex Equity Investment Fund Partnership holds a 40% stake. It should be noted that the Jinan Zurich fund acquired Annex this past June in a $5 billion deal.

Now, there’s another flying race car concept in the game. French startup Maca Flight revealed a new hydrogen-powered flying race car concept at the 2022 CES and it’s remarkably similar to the podracers in the Star Wars universe.

A green flying race car concept

Called a carcopter, a portmanteau of the words car and helicopter, Maca S11 is designed for speed and sustainability. And unlike others in its class, it’s powered by a hydrogen fuel cell instead of a conventional battery. The company states that the eVTOL is priced at just over $900,000 and that it will be ready to hit the racetrack in 2023.

The business mogul’s opening up to more ‘free speech’ on Twitter may have ruffled some feathers.

Elon Musk might have just hinted at making Tesla phones (Tesla Pi) a reality if Apple and Google were to “boot” Twitter from their app stores.

“If Apple & Google boot Twitter from their app stores, @elonmusk should produce his own smartphone,” Liz Wheeler, a video podcaster, said in a Twitter thread on Friday.
