Novel device harvests drinking water from humidity around the clock

Posted by in categories: energy, space, sustainability

Freshwater is scarce in many parts of the world. While currently there is enough fresh water on earth to support consumption, it is not available in a way where supply meets demand. To solve this issue, engineers at ETH Zurich have developed a new device that can harvest drinking water 24 hours around the clock, with no energy input, even under the blazing sun.

It consists of a specially coated glass pane, which both reflects solar radiation and also radiates away its own heat through the atmosphere to outer space. The resulting device thus cools itself down to as much as 15 degrees Celsius below the ambient temperature. At the bottom of the pane, the moisture in the air condenses into the water which is collected.

The glass pane is coated with layers of a specially designed polymer and silver, which allows it to firstly reflect sunlight away to prevent it from heating up. The coating causes the pane to emit infrared radiation at a specific wavelength window to the outer space, with no absorption by the atmosphere nor reflection back onto the pane.

Making A Future Better Together. A Vision Of A Pathway

Posted by in categories: energy, futurism

Are we governed by donkeys? COP26 was just a farce of vested interests kissing the butts of fossil fuel legacy industries that are so out of date that they cannot compete anymore and need underhand, secret handshake deals just to keep themselves in the luxury they enjoy…at our expense. So here is my Manifesto for the next decade. It is time to start voting for the right people and harassing your representatives to get them to make the right decisions that will benefit the majority, not a few CEO’s who are so corrupt it is like the plot of a new film…

Exclusive: IBM achieves quantum computing breakthrough

Posted by in categories: energy, quantum physics, supercomputing

IBM has created a quantum processor able to process information so complex the work can’t be done or simulated on a traditional computer, CEO Arvind Krishna told “Axios on HBO” ahead of a planned announcement.

Why it matters: Quantum computing could help address problems that are too challenging for even today’s most powerful supercomputers, such as figuring out how to make better batteries or sequester carbon emissions.

Driving the news: IBM says its new Eagle processor can handle 127 qubits, a measure of quantum computing power. In topping 100 qubits, IBM says it has reached a milestone that allows quantum to surpass the power of a traditional computer.

Reaction Engines assembles partners for its ammonia aviation project

Posted by in categories: economics, energy, transportation

The UK’s Reaction Engines has announced a joint venture to create compact, lightweight ammonia reactors it says can be used to decarbonize difficult sectors like shipping and off-grid energy generation – and surprisingly, also aviation.

We’ve written before about ammonia’s potential in the clean transport sector; check out our ammonia clean fuel primer piece from September. Compared against hydrogen, ammonia’s much easier and cheaper to store and transport, and although it only carries about 20 percent as much energy as hydrogen by weight, it carries about 70 percent more energy than liquid H2 by volume.

The weight issue generally rules ammonia out of aviation discussions; at less than half the specific energy of jet fuel it looks less attractive than hydrogen. But hydrogen’s volume issues must also be taken into account. Today’s airliners are built for jet fuel so retro-fitting large-volume long-range hydrogen tanks can mean you lose seats. And anyone who’s flown economy can attest, airlines really like fitting in as many seats as they can.

Space startup wants to sling satellites into orbit with a huge centrifuge

Posted by in categories: energy, satellites

In a nutshell: In the 21st century, there’s a new space race, primarily between Tesla (SpaceX) and Amazon (Blue Origin). Both are concentrating on traditional methods of launching satellites into space—namely, big rockets. However, a small space startup called SpinLaunch is developing a cheaper and environmentally cleaner way of launching satellites.

SpinLaunch is using a gigantic centrifuge to shoot stuff into space. By “stuff,” we mean things that can withstand the G-force created by being spun at 5,000 miles per hour (over 10,000 Gs), which is a category of stuff that does not yet include satellites. However, it did launch a missile-like projectile tens of thousands of feet into the air last month, using only 20 percent of the accelerator’s power.

Newly developed compound may enable sustainable, cost-effective, large-scale energy storage

Posted by in categories: chemistry, energy, engineering, sustainability

To produce a cost-effective redox flow battery, researchers based at the South China University of Technology have synthesized a molecular compound that serves as a low-cost electrolyte, enabling a stable flow battery that retains 99.98% capacity per cycle. They published their approach on August 14 in the Energy Material Advances.

Comprising two tanks of opposing liquid electrolytes, the battery pumps the positive and negative liquids along a membrane separator sandwiched between electrodes, facilitating ion exchanges to produce energy. Significant work has been dedicated to developing the negative electrolyte liquid, while the positive electrolyte liquid has received less attention, according to corresponding author Zhenxing Liang, professor in the Key Laboratory of Fuel Cell Technology of Guangdong Province, School of Chemistry and Chemical Engineering, South China University of Technology.

“Aqueous redox flow batteries can realize the stable electrical output for using unsteady solar and wind energy, and they have been recognized as a promising large-scale energy storage ,” Liang said. “Electroactive organic merit of element abundance, low cost and flexible molecular control over the electrochemical features for both positive and negative electrolytes are regarded as key to developing next-generation redox flow batteries.”
