Magnetically stirred electrolyte puts high-density batteries in the mix

Posted by in categories: mobile phones, sustainability, transportation

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.

Singing inverters show electrical harmony for renewable power systems

Posted by in categories: energy, finance, sustainability, transportation

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.

Tesla’s sinking stock price pushes Elon Musk to #2 on the world’s richest list

Posted by in categories: Elon Musk, policy, sustainability, transportation

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.

Elon’s AGILE Takeover (of Twitter) | Experts don’t get Elon bc Experts don’t get AGILE!

Posted by in categories: bioengineering, business, Elon Musk, sustainability, transportation

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.

A new electric car battery material could dramatically boost charging times

Posted by in categories: sustainability, transportation

The technology could help make EVs more affordable as well as easier to charge.

A collaboration between researchers at the Yokohoma National University in Japan and the University of New South Wales Sydney, Australia has led to the development of a new electrode material that can be used in solid-state batteries. Thus the electrode doesn’t diminish after multiple charges and discharge cycles and can help in manufacturing durable batteries for electric vehicles.

As the world is turning over to electric modes of transportation in its bid to reduce carbon emissions, the battery has become a focal area of development.

This gold-based transparent coating will end glasses fog forever

Posted by in category: transportation

This gold coating is the perfect weapon to kill fog.

What if there was a way to keep our eyeglasses, windows, and car windshields free of fog all the time? Of course, we can use those anti-fog sprays, but the problem with such applications is that we have to apply them again and again.

A team of researchers at the Swiss Federal Institute of Technology (ETH Zurich) has the perfect long-lasting solution to our fog problem. They recently filed a patent application for an ultrathin and 100 percent transparent coating that performs defogging (removing existing fog on a surface) and anti-fogging (preventing the formation of fog on a surface).
