Munich’s Sono Motors are about to launch the first mass-produced solar powered car in the world, the Sion, with solar panels all over it.

As levels of atmospheric carbon dioxide continue to climb, scientists are looking for new ways of breaking down CO₂ molecules to make useful carbon-based fuels, chemicals and other products. Now, a team of Brown University researchers has found a way to fine-tune a copper catalyst to produce complex hydrocarbons—known as C2-plus products—from CO₂ with remarkable efficiency.

In a study published in Nature Communications, the researchers report a catalyst that can produce C2-plus compounds with up to 72% faradaic efficiency (a measure of how efficiently electrical energy is used to convert carbon dioxide into chemical reaction products). That’s far better than the reported efficiencies of other catalysts for C2-plus reactions, the researchers say. And the preparation process can be scaled up to an industrial level fairly easily, which gives the new catalyst potential for use in large-scale CO₂ recycling efforts.

“There had been reports in the literature of all kinds of different treatments for copper that could produce these C2-plus with a range of different efficiencies,” said Tayhas Palmore, the a professor of engineering at Brown who co-authored the paper with Ph.D. student Taehee Kim. “What Taehee did was a set of experiments to unravel what each of these treatment steps was actually doing to the catalyst in terms of reactivity, which pointed the way to optimizing a catalyst for these multi-carbon compounds.”

Technology that can convert salty seawater or brackish water into safe, clean drinking water has the potential to transform millions of lives across the globe, which is why so many scientists are busy working on projects to do just that.

Now, a new innovation developed by scientists in Australia could be the most promising one yet, with researchers using metal-organic framework compounds (or MOFs) together with sunlight to purify water in just half an hour, using a process that’s more efficient than existing techniques.

It’s cheap, it’s stable, it’s reusable, and it produces water that meets the World Health Organisation (WHO) standards for desalination. Around 139.5 litres (nearly 37 gallons) of clean water can be produced per day from a kilogram (2.2 pounds) of MOF material, based on early testing.

Tesla’s stock (TSLA) is surging 18% over the last few days as investors are getting in just before Battery Day and the important announcements that it will bring. On Wednesday, Tesla announced a 5 for 1 stock split that sent the stock price surging.

Despite stock splits not actually changing the value of a company, they have been known to increase stock prices temporarily as people anticipate higher volume from small investors.

A team of researchers working at the University of Maryland has uncovered the structure of the mysterious blue whirling flame. In their paper published in the journal Science Advances, the group describes using computer simulations to determine the structure of the unique type of flame.

Back in 2016, a team of researchers discovered what they described as a blue whirling flame while they were studying the properties of liquid fuel floating on water. They had added fuel to a tank full of water that was enclosed in a space that generated a vortex. They described a fire that looked at first like a tornado, but then shortly after, settled into what they dubbed a blue whirling flame. They noted at the time that its color suggested it likely was very efficient, burning the fuel without creating soot—a property that might be useful in cleaning up oil spills. Since then, others have looked at the unique type of flame, but no one had tried to understand its structure. In this new effort, the researchers took a closer look at the flame and found it was actually three types of flames that had merged into one.

To learn more about the nature of the blue whirling flame, the researchers created computer simulations using conditions known to generate them. They then slowly adjusted the parameters until they were able to generate the flame virtually. They discovered that the flame was actually the result of three known types of flames merging: those with an invisible outer flame, which happens when there is less fuel than oxygen in the mix—and two that had types of visible inner flames in which higher fuel ratios are more common.

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 potable water for millions of people across the world, researchers were not only able to filter harmful particles from water 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.”

Researchers from Germany sent solar cells into low-Earth Orbit to see how well they might perform in longer, deep space missions.
