Elon Musk confirms a new low-cost Tesla model is coming in 2025

Posted by in categories: Elon Musk, sustainability, transportation

Tesla is reportedly working on compact crossover EV codenamed “Redwood” with production set to start in June 2025, sources familiar with the matter told Reuters. The company is said to have sent requests for quotes for the new model to suppliers last year, predicting a weekly production volume of 10,000 vehicles.

Elon Musk has confirmed that a “next-generation low-cost” Tesla EV is in the works and is “optimistic” that it’ll arrive in the second half of 2025, he said in an earnings call yesterday. He also promised “a revolutionary manufacturing system” for the vehicle that’s far more advanced than any others in the world by a “significant margin.”

An article yesterday from Reuters indicated that the new vehicle would be a small crossover codenamed “Redwood.” Tesla reportedly sent requests to suppliers for quotes, predicting a weekly production volume of 10,000 vehicles. Musk previously stated that the automaker is working on two new EV models that could sell up to 5 million per year, combined.

Tesla confirms new Model 3 Performance configuration is coming

Posted by in categories: sustainability, transportation

Tesla has confirmed a new Model 3 Performance configuration is coming, but the big questions of when it is and what changes it will have remain up in the air.

Early in 2024, Tesla removed the Performance configuration from the Model 3’s list of available trims. It was the most expensive of the three Model 3 offerings, but it still qualified for the EV Tax Credit.

With the rollout of the new Model 3 ‘Highland’ globally, Tesla has not yet finalized a Performance version of the vehicle. Currently, it only offers two variants: the Rear-Wheel-Drive and Long Range.

Invisible Armor for Steel: How hBN Coating Is Reinventing Metal Durability

Posted by in categories: solar power, sustainability

Hexagonal boron nitride coatings on metal alloys enhance durability, reduce friction, and protect against harsh conditions, paving the way for improvements in solar panels, semiconductors, and aerospace components.

Researchers demonstrated that stainless steel and other metal alloys coated with hexagonal boron nitride, or hBN, exhibit non-stick or low-friction qualities along with improved long-term protection against harsh corrosion and high-temperature oxidation in air.

Metal alloys — mixtures of two or more metals — are created to be strong, durable, and resistant to corrosion or oxidation. By adding coatings, or “armor,” to make those materials even tougher, scientists could enhance existing products and enable the creation of new, innovative ones.

Beyond Silicon: New Sustainable Method for Creating Organic Semiconductors

Posted by in categories: solar power, sustainability

Researchers at Linköping University, Sweden, have developed a new, more environmentally friendly way to create conductive inks for use in organic electronics such as solar cells, artificial neurons, and soft sensors. The findings, published in the journal Nature Communications, pave the way for future sustainable technology.

Organic electronics are on the rise as a complement and, in some cases, a replacement to traditional silicon-based electronics. Thanks to simple manufacturing, high flexibility, and low weight combined with the electrical properties typically associated with traditional semiconductors, it can be useful for applications such as digital displays, energy storage, solar cells, sensors, and soft implants.

Challenges in Organic Electronics.

Cornell researchers develop breakthrough EV battery that charges under 5 mins

Posted by in categories: engineering, sustainability, transportation

A research team led by Lynden Archer, professor and dean of Cornell Engineering, has developed a new lithium battery that can charge in as little as five minutes. This could help address anxiety associated with the charging time of electric vehicles (EVs) and increase their adoption.

In their bid to reduce emissions from transportation, countries worldwide are looking to electrify various modes of transport. Road-based transport such as cars, buses, and trucks have led this transformation, aiming to even ban the sale of fossil fuel-powered cars in the next decade.

With technological advances, the fastest commercial charger can charge up an EV in no less than 30 minutes. While this might be a major improvement over the 8-hour charge cycles of a typical home-based charger, it still needs to be improved for large-scale adoption of EVs.

Researchers grow a twisted multilayer crystal structure for next-gen materials

Posted by in categories: computing, quantum physics, solar power, sustainability

Researchers with the Department of Energy’s SLAC National Accelerator Laboratory, Stanford University and the DOE’s Lawrence Berkeley National Laboratory (LBNL) have grown a twisted multilayer crystal structure for the first time and measured the structure’s key properties. The twisted structure could help researchers develop next-generation materials for solar cells, quantum computers, lasers and other devices.

“This structure is something that we have not seen before—it was a huge surprise to me,” said Yi Cui, a professor at Stanford and SLAC and co-author of a paper published in Science describing the work. “A new quantum electronic property could appear within this three-layer twisted structure in future experiments.”

New Fuel Cell Harvests Energy from Microbes in Soil to Power Sensors, Communications

Posted by in categories: biological, chemistry, food, sustainability

A Northwestern University-led team of researchers has developed a new fuel cell that harvests energy from microbes living in dirt.

About the size of a standard paperback book, the completely soil-powered technology could fuel underground sensors used in precision agriculture and green infrastructure. This potentially could offer a sustainable, renewable alternative to batteries, which hold toxic, flammable chemicals that leach into the ground, are fraught with conflict-filled supply chains and contribute to the ever-growing problem of electronic waste.

To test the new fuel cell, the researchers used it to power sensors measuring soil moisture and detecting touch, a capability that could be valuable for tracking passing animals. To enable wireless communications, the researchers also equipped the soil-powered sensor with a tiny antenna to transmit data to a neighboring base station by reflecting existing radio frequency signals.
