Visualizing the World in 2090

In some ways, the world in 2090 may resemble the world we live in today. Yet, two key areas will almost certainly change: the natural world and technology. Will our thirst for consumption ultimately deplete the world’s most critical natural resources? Or will technology help us persevere? And how will innovation change the way we move, work, and explore? Today, we’ll take a deep dive into these captivating questions.

Nikola Tesla Secret Inventions That Were Lost or Censored

While there is still much mystery surrounding the life and death of Nikola Tesla, perhaps the most intriguing of mysteries lay in his inventions that never fully saw the light of day. Inventions such as the Death Ray, the Earthquake machine, his flying vehicles, and much more. With the intellect and creative prowess he possessed, we can only begin to imagine the thoughts and ideas he had but never shared.

What we do have, is a small fraction, a record of the incredible inventions that he either discussed, began building, or had actual working prototypes. These were never fully developed or deployed, at least not to the public knowledge, but had the potential to be world-changing… some for better and some for worse… Narration: Petra Ortiz — http://petraortiz.com Scences from History Channel were used under Fair Use.

Cyberthreats lurk at Messi vs. Mbappé FIFA World Cup final match as 5 billion prepare to watch

More than 15,000 cameras have been placed throughout the eight stadiums and along roads and transportation infrastructure in Doha.

As Lionel Messi faces Kylian Mbappé in Argentina vs France World Cup final match in Qatar, which billions prepare to watch, cybersecurity experts warn that the event may be a hotspot for cyber threats.

“With major sporting events becoming increasingly digitized, the attack surface for threat actors has also increased,” a recent ZeroFox report on World Cup threats stated.

Cyberthreats lurk as five billion people prepare to watch the World Cup final, according to an article by Dark Reading published on Friday.

Could Twitter Be Elon Musk’s ‘Greatest Investment Ever’? Jim Cramer Isn’t Betting Against The ‘Underestimated’ Tesla CEO

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.

World’s first net-zero transatlantic flight: Fly London to New York on used cooking oil

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.

Scientists find material with highest toughness ever recorded

“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.

Elon Musk sells nearly $3.6 billion of Tesla stock this week

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.

Magnetically stirred electrolyte puts high-density batteries in the mix

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.
