Silicon, the standard semiconducting material used in a host of applications—computer central processing units (CPUs), semiconductor chips, detectors, and solar cells—is an abundant, naturally occurring material. However, it is expensive to mine and to purify.
University of Cambridge, working with colleagues from Austria, found a new way to make a possible replacement for rare-earth magnets: tetrataenite, a ‘cosmic magnet’ that takes millions of years to develop naturally in meteorites.
Previous attempts to make tetrataenite in the laboratory have relied on impractical, extreme methods. But the addition of a common element — phosphorus — could mean that it’s possible to make tetrataenite artificially and at scale, without any specialised treatment or expensive techniques.
The results are reported in the journal Advanced Science. A patent application on the technology has been filed by Cambridge Enterprise, the University’s commercialisation arm, and the Austrian Academy of Sciences.
During an interview with BBC journalist Amol Rajan, Bill Gates argued against accusations he’s a hypocrite for using a personal private jet while also investing in climate change solutions.
On a cold winter day, the warmth of the sun is welcome. Yet as humanity emits more and more greenhouse gases, the Earth’s atmosphere traps more and more of the sun’s energy and steadily increases the Earth’s temperature. One strategy for reversing this trend is to intercept a fraction of sunlight before it reaches our planet. For decades, scientists have considered using screens, objects or dust particles to block just enough of the sun’s radiation—between 1 or 2%—to mitigate the effects of global warming.
A University of Utah-led study explored the potential of using dust to shield sunlight. They analyzed different properties of dust particles, quantities of dust and the orbits that would be best suited for shading Earth. The authors found that launching dust from Earth to a way station at the “Lagrange Point” between Earth and the sun (L1) would be most effective but would require astronomical cost and effort. An alternative is to use moondust. The authors argue that launching lunar dust from the moon instead could be a cheap and effective way to shade the Earth.
ABB is today launching an innovative all-in-one Electric Vehicle (EV) charger, which provides the fastest charging experience on the market.
ABB’s new Terra 360 is a modular charger which can simultaneously charge up to four vehicles with dynamic power distribution. This means that drivers will not have to wait if somebody else is already charging ahead of them. They simply pull up to another plug. The new charger has a maximum output of 360 kW and is capable of fully charging any electric car in 15 minutes or less, meeting the needs of a variety of EV users, whether they need a fast charge or to top their battery up while grocery shopping.
“With governments around the world writing public policy that favors electric vehicles and charging networks to combat climate change, the demand for EV charging infrastructure, especially charging stations that are fast, convenient and easy to operate is higher than ever,” said Frank Muehlon, President of ABB’s E-mobility Division. “The Terra 360, with charging options that fit a variety of needs, is the key to fulfilling that demand and accelerating e-mobility adoption globally.”
Amazon founder Jeff Bezos’ space firm, Blue Origin, announced it has developed a method for producing solar cells and transmission wire using only lunar regolith.
Blue Origin famously filed a legal complaint against NASA after it snubbed its lunar lander design in favor of awarding SpaceX a contract for a modified Starship lander.

The 2021 IPCC report, however, urged scientists and engineers to double down on renewable energy efforts and consider all options.
Feb 14 (Reuters) — Tesla chief executive Elon Musk donated shares worth $1.95 billion in the world’s most valuable automaker to charity last year, a filing with the U.S. Securities and Exchange Commission (SEC) showed on Tuesday.
Musk donated about 11.6 million shares between August and December last year, according to the filing, which did not say which organization or organizations were the recipients.
The world’s second-richest person now owns around 13% of Tesla.

The losses for short-sellers betting against Elon Musk’s electric vehicle company have ballooned to $7.6 billion over the past month, making it the least profitable short position for hedge funds, according to data from S3 Partners.
The swift one-month surge in Tesla stock has wiped out about half of the gains short-sellers made last year betting against the company. At the end of December, short-sellers had made a $15 billion profit in 2022, making Tesla the most profitable short of the year.
Shares of Tesla have been on a rollercoaster following vehicle price cuts and a weaker-than-expected fourth-quarter delivery number. But on the company’s most recent earnings call, Musk reaffirmed the company’s long-term growth target of 50%.
