The team has successfully tested a sustainable membrane-based seawater electrolyzer.

A research team in China has developed a device to split salty seawater to produce hydrogen directly. The device, a membrane-based seawater electrolyzer, helps address the side-reaction and corrosion problems of traditional methods.

Why traditional methods are not sustainable.

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.

Colombian renewable energy startup E-Dina developed a wireless lantern, called WaterLight, that converts salt water into electricity and is more reliable than solar-powered lamps, a Dezeen article explains. And it can also be charged by urine in emergency situations.

The portable device acts as a mini generator that produces light using ionization — by filling it with 500 milliliters of seawater, the salt in the water reacts with magnesium and copper plates inside the device, converting it into electrical energy.

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 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 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 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.

Global payments giant Visa says it will invest $1 billion by 2027 to expand its investments in Africa amidst a digital payments boom on the continent.

Visa chief Al Kelly announced this pledge on Wednesday during the U.S.-Africa Business Forum, a sub-event in the broader U.S.-Africa Leaders Summit, a three-day event where U.S. President Joe Biden invited heads of state and senior government officials from Africa to discuss several issues ranging from food security to climate change.

“Visa has been investing in Africa for several decades to grow a truly local business, and today our commitment to the continent remains as firm and unwavering as ever,” said the Visa CEO in a statement.

MSM and Experts fail to see the logic in how Elon Musk is taking over Twitter. They think it’s chaos, a mess, he’s out of his depth. But Elon is just working AGILE, and AGILE always seems like a mess to onlookers used to traditional work!
The video describes Elon’s Agile Takeover of Twitter and shows the opportunity worth BILLION$ that Elon Musk has ALREADY unlocked.
