In April, Tesla Inc TSLA CEO Elon Musk said he was done selling Tesla shares to help finance his ongoing overhaul at Twitter.
Since then, he jettisoned more than $20 billion worth of Tesla stock and has continued the selling spree this week.
As the stock continues to skid, Jim Cramer sees an electric buying opportunity.
The United Kingdom government has announced that Virgin Atlantic will fly a historic net zero London-New York flight in 2023.
“For decades, flying from London to New York has symbolized aviation’s ability to connect people and drive international progress. It’s now going to be at the forefront of cutting carbon emissions from flying,” said British transport secretary Mark Harper.
“Not only will this flight pave the way for future generations, but it will demonstrate just how much we can achieve when we work together on a shared goal — bringing together some of the best businesses and academics in the world and led by a British airline.”
Rolls-Royce Trent 1,000 engines will power the airline’s flagship Boeing 787s as they fly from London Heathrow to New York.

“The toughness of this material near liquid helium temperatures (20 kelvin, −253°C) is as high as 500 megapascals square root metres,” said Robert Ritchie, Professor of Mechanical Engineering at Berkeley and study co-author. “In the same units, the toughness of a piece of silicon is one, the aluminium airframe in passenger airplanes is about 35, and the toughness of some of the best steels is around 100. So, 500, it’s a staggering number.”
The team’s new findings, alongside other recent work on HEAs, may force the materials science community to reconsider long-held notions about how physical characteristics give rise to performance.
“It’s amusing, because metallurgists say that the structure of a material defines its properties, but the structure of the CrCoNi is the simplest you can imagine – it’s just grains,” explained Ritchie.
Making the total amount of sold Tesla stocks nearly $40 billion over the past year.
Tesla CEO, Elon Musk, has been on a selling spree of his company’s stock this year. Earlier this week, Musk sold 22 million shares over a period of three days, a filing with the U.S. financial regulator has revealed, the BBC
Musk, who rose to the top of the world’s wealthiest people list last year riding on Tesla stock price, has spent most of 2022 dealing with this start-again-stop-again campaign to acquire Twitter. Musk, who was quite secretive about acquiring Twitter stock at the beginning of the year, shocked many by declaring his intent to buy out the social media company and take it private.
Next-generation batteries could take on many forms, but one design that scientists are pinning a lot of hope on involves the use of lithium metal. The excellent energy density of this material could see batteries power smartphones for days at a time, and by designing a new electrolyte that can be controlled by an external magnetic fields, scientist in South Korea have edged them a little closer to reality.
A lithium-metal battery is one that would see this material deployed in place of the graphite and copper used in the anode of today’s lithium-ion batteries. This could make for smaller and lighter anodes with far superior energy density, which could see smartphones require far fewer charges each week or an electric vehicle travel much farther on each charge.
But one problem researchers continue to run into is the growth of tentacle-like protrusions on the anode called dendrites, which swiftly cause the battery to fail. There is no shortage of potential solutions when it comes to addressing this issue, and now a team at the Daegu Gyeongbuk Institute of Science and Technology have thrown another bright idea into the mix.
Uber and Cartken have announced a partnership to introduce Miami to a fleet of tiny autonomous delivery vehicles.
Top Tesla investors are growing frustrated with billionaire Elon Musk’s focus on Twitter as the electric car company’s stock prices continue to fall this month.
Standing among solar arrays and power grid equipment at the National Renewable Energy Laboratory (NREL), you might hear a faint, distorted melody buzzing from somewhere. You are not hallucinating—that gray box really is singing the Star Wars Theme, or the ice cream truck song, or Chopin’s Waltz in A minor. Power system engineers are just having some fun with an NREL capability that prevents stability problems on the electrical grid.
Usually, the engineers send another kind of waveform through the inverters and load banks: megawatts of power and voltage vibrations at many frequencies. The purpose of their research is to see how energy devices and the grid interact—to get them “in tune” and prevent dangerous electrical oscillations that show up like screechy feedback or a booming sub-bass.
The engineers can do this analysis at high fidelity with NREL hardware using the lab’s advanced impedance measurement system, and they have also produced a commercially available software called the Grid Impedance Scan Tool or GIST that can do the same with simulated power on device models, allowing any manufacturer or grid operator to certify grid stability with renewable energy resources.

Musk’s attention to Twitter is hurting his bread and butter.
Since September last year, Elon Musk has been regarded as the world’s richest person. The stock price of the electric vehicle-making company Tesla has been the sole reason behind his dramatic rise to the top. With Tesla stock dropping 50 percent value since the beginning of the year, Musk has now dropped to number two on the list of the world’s richest people, Bloomberg.

In April, Musk announced his decision to buy out Twitter and take the social media company private to unlock its true potential. The timing of his offer could not be worse as the U.S. Federal Bank began tightening its fiscal policy to rein in inflation. Within days, Musk’s $44 billion offer seemed a price too high to pay, as the stock prices of tech companies began shrinking with higher interest rates.
