New Lantern Is Better Than Solar and Can Be Charged

Posted by in categories: energy, sustainability

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.

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.

Visa to invest $1B in Africa over the next five years

Posted by in categories: business, climatology, government, sustainability

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.

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.

Producing ‘green’ energy from living plant ‘bio-solar cells’

Posted by in categories: biological, chemistry, food, solar power, sustainability

Though plants can serve as a source of food, oxygen and décor, they’re not often considered to be a good source of electricity. But by collecting electrons naturally transported within plant cells, scientists can generate electricity as part of a “green,” biological solar cell.

Now, researchers reporting in ACS Applied Materials & Interfaces have, for the first time, used a succulent plant to create a living “bio-solar cell” that runs on photosynthesis.

In all , from bacteria and fungi to and animals, electrons are shuttled around as part of natural, biochemical processes. But if electrodes are present, the cells can actually generate electricity that can be used externally. Previous researchers have created fuel cells in this way with bacteria, but the microbes had to be constantly fed. Instead, scientists, including Noam Adir’s team, have turned to photosynthesis to generate current.

United Nations General Assembly approves ASAT test ban resolution

Posted by in categories: military, satellites, sustainability

WASHINGTON — The United Nations General Assembly approved a resolution calling for a halt to one type of anti-satellite (ASAT) testing, a largely symbolic move intended to support broader space sustainability initiatives.

The resolution, introduced by the United States and several other nations, was approved by the U.N. General Assembly Dec. 7 among dozens of other resolutions on arms control and related topics with little discussion or debate. A total of 155 nations voted in favor of the resolution, with 9 voting against it and 9 others abstaining.

The resolution calls on countries to halt destructive testing of direct-ascent ASAT weapons, citing concern that such creates large amounts of debris that threaten the safety of other satellites. An example is the November 2021 ASAT test by Russia that destroyed the Cosmos 1,408 satellite, creating nearly 1,800 tracked pieces of debris and likely many more objects too small to be tracked. About a third of the tracked debris from that test was still in orbit nearly a year later.

Becoming a Kardashev Type I Civilization

Posted by in categories: energy, media & arts, space, sustainability

The Kardashev Scale has become a standardized way of classifying (hypothetical) advanced civilizations. The lowest rank, Type 1, is still way ahead of us — but by how much? When will we achieve Type 1 status and exactly how could we plausibly do so? In this video, we go through some estimates of when humanity might become Type 1, and in particular what kind of energy sources we could harness to achieve this feat.
