A global research team has been able to transform brackish water and seawater into safe, clean drinking water in less than 30 minutes using metal-organic frameworks (MOFs) and sunlight.

In a discovery that could provide for millions of people across the world, researchers were not only able to filter harmful particles from and generate 139.5L of clean water per kilogram of MOF per day, but also perform this task in a more energy-efficient manner than current desalination practices.

The World Health Organization suggests good quality drinking water should have a total dissolved solid (TDS) of 600 parts per million (ppm). Researchers were able to achieve a TDS of 500 ppm in just 30 minutes and regenerate the MOF for reuse in four minutes under sunlight.

Tesla’s highly-anticipated Battery Day is still several weeks away, but CEO Elon Musk appears to have started posting cryptic teasers about some of the innovations that would be introduced at the event. Based on a recent post on Twitter, it appears that Tesla’s Plaid Model S, and perhaps even the Plaid Model X, may be unveiled at Battery Day.

Ever the internet’s resident meme lord, Elon Musk recently posted a photo of Herbert Ruggles Tarlek, Jr., a character on the television situation comedy WKRP in Cincinnati, which ran from 1978 to 1982. The character was noted for his loud plaid suits, which were usually dominated by bold colors and patterns. Musk’s tweet noted that “One day soon, I will wear this outfit.”

What if you could solve two of Earth’s biggest problems in one stroke? UC Riverside engineers have developed a way to recycle plastic waste, such as soda or water bottles, into a nanomaterial useful for energy storage.

Mihri and Cengiz Ozkan and their students have been working for years on creating improved materials from sustainable sources, such as glass bottles, beach sand, Silly Putty, and portabella mushrooms. Their latest success could reduce plastic pollution and hasten the transition to 100% clean .

“Thirty percent of the global car fleet is expected to be electric by 2040, and high cost of raw battery materials is a challenge,” said Mihri Ozkan, a professor of electrical engineering in UCR’s Marlan and Rosemary Bourns College of Engineering. “Using from landfill and upcycling could lower the total cost of batteries while making the battery production sustainable on top of eliminating plastic pollution worldwide.”

Researchers at Argonne National Laboratory say they’ve found a breakthrough way to recycle carbon dioxide into energy-rich ethanol fuel. The secret is an electrified catalyst made from copper and carbon, which the researchers say can be powered using low-cost off-peak or renewable energy. What results is a process that’s more than 90 percent effective, which they say is far higher than any similar existing process.

Northern Illinois University professor and participating Argonne researcher Tao Xu says the new catalyst isn’t just a single stop that can produce ethanol—it’s the first step down a possible long list of ways to turn carbon dioxide into other useful chemicals. Despite the obvious plenitude of carbon dioxide, recycling it effectively into new things has been hard because of how stable and chemically stubborn the molecules are.

Tesla studies the possibility of becoming an energy supplier in Europe, offering photovoltaic, storage and electric car charging in one package.

Tesla doesn’t just sell cars. Among the various sectors in which it operates, domestic energy is perhaps the one with the widest growth margins. After launching its photovoltaic products, both solar panels, and tiles, and after the famous PowerWall accumulation, Musk’s company is studying the possibility of offering all its assets in a single offer, even becoming an electricity provider in the world.

It would be a very important step, which would allow Tesla to manage all the variables in an integrated way, including the charging of electric cars. The novelty was discovered through a survey that the same company distributed to customers in Germany, with questions that left room for few doubts:

Tesla is going to work with spaceships too. Enhanced partnership with SpaceX.

This is revealed by a new job position, for future designers who will range from electric cars to spaceships for Mars.

A couple of days ago SpaceX tested a prototype of the future Starship, the spacecraft that will be flying to the Moon and Mars. It was a rather raw reproduction, just slightly reminiscent of the style used in the digital rendering presentation. Today we discover that, as demonstrated by a new job place, Tesla’s may be called into the final design.

Tesla, in fact, looking for new experts, specifies that the tasks for future designers who will range from electric cars to spaceships for Mars. The growing collaboration between the two Elon Musk companies is therefore evident.

BYD, one of the world’s largest electric bus manufacturer, boasted recently that its zero-emission buses already covered more than 13 million miles (21 million km) in the U.S.

The buses sold in North America are made in Lancaster, California, where local transit agency — the Antelope Valley Transit Authority (AVTA) — just crossed the 3-million-mile mark of zero-emission operations using BYD buses.

Overall, the company sold buses to more than 50 customers across the country. According to BYD, the total mileage translated into:

NASA’s Perseverance Mars rover launched from Cape Canaveral, Florida, on 30 July, carrying a host of cutting-edge technology including high-definition video equipment and the first interplanetary helicopter.

Many of the tools are designed as experimental steps toward human exploration of the red planet. Crucially, Perseverance is equipped with a device called the Mars Oxygen In-Situ Resource Utilization Experiment, or MOXIE: an attempt to produce oxygen on a planet where it makes up less than 0.2 percent of the atmosphere.

Oxygen is a cumbersome payload on space missions. It takes up a lot of room, and it’s very unlikely that astronauts could bring enough of it to Mars for humans to breathe there, let alone to fuel spaceships for the long journey home.

#SpaceWatchGL Opinion: Space Traffic Management – Impact of Large Constellations on Military Operations in Space.

🌚 #SpaceWatchGL

As part of the partnership between SpaceWatch. Global and Joint Air Power Competence Centre, we have been granted permission to publish selected articles and texts. We are pleased to present “Space Traffic Management – Impact of Large Constellations on Military Operations in Space”, originally published by the Joint Air Power Competence Centre for the Conference Read Ahead 2020.

by Mr. Marc Becker, DLR Space Administration, Bonn, Germany

As Space Actors Consolidate their Approaches to Space Traffic Management, What is the Role of the Military?

Space Traffic Management (STM) is currently one of the hottest topics in space policy. While a consensual definition of the term is yet to emerge, it becomes increasingly clear that the international community has to find ways to protect space infrastructure and guarantee the safe and sustainable use of outer space in the long run, amid an ever-growing number of actors and objects in the space domain.
