Liquid Air Energy Storage: A Power Grid Battery Using Regular Old Ambient Air

Posted by in categories: energy, sustainability

When you think of renewable energy, what comes to mind? We’d venture to guess that wind and solar are probably near the top of the list. And yes, wind and solar are great as long as the winds are favorable and the sun is shining. But what about all those short and bleak winter days? Rainy days? Night time?

Unfavorable conditions mean that storage is an important part of any viable solution that uses renewable energy. Either the energy itself has to be stored, or else the means to produce the energy on demand must be stored.

One possible answer has been right under our noses all along — air. Regular old ambient air can be cooled and compressed into a liquid, stored in tanks, and then reheated to its gaseous state to do work.

Unusual nanoparticles could benefit the quest to build a quantum computer

Posted by in categories: biological, chemistry, climatology, computing, engineering, nanotechnology, quantum physics, sustainability

Imagine tiny crystals that “blink” like fireflies and can convert carbon dioxide, a key cause of climate change, into fuels.

A Rutgers-led team has created ultra-small dioxide crystals that exhibit unusual “blinking” behavior and may help to produce methane and other fuels, according to a study in the journal Angewandte Chemie. The crystals, also known as nanoparticles, stay charged for a long time and could benefit efforts to develop quantum computers.

“Our findings are quite important and intriguing in a number of ways, and more research is needed to understand how these exotic crystals work and to fulfill their potential,” said senior author Tewodros (Teddy) Asefa, a professor in the Department of Chemistry and Chemical Biology in the School of Arts and Sciences at Rutgers University-New Brunswick. He’s also a professor in the Department of Chemical and Biochemical Engineering in the School of Engineering.

Space technology is improving our lives and making the world a better place. Here’s how

Posted by in categories: climatology, habitats, internet, satellites, sustainability

“We need to go to space to help us here on Earth. Satellites have played an enormous role in improving the state of the world, and will do even more”.


I’m often asked: ‘Why are you building satellites for space when there are so many problems to fix here on Earth?’ It’s a perfectly rational question. The short answer is that we need to go to space to help us here on Earth. Satellites have played an enormous role in improving the state of the world, and will do even more as an explosion of technology innovation enables large new fleets of small satellites to be deployed with radical new capabilities.

New Integrated 3D-Circuit Architecture With Spiraling Memory for More Efficient AI

Posted by in categories: climatology, information science, robotics/AI, sustainability

Researchers from the Institute of Industrial Science at The University of Tokyo designed and built specialized computer hardware consisting of stacks of memory modules arranged in a 3D-spiral for artificial intelligence (AI) applications. This research may open the way for the next generation of energy-efficient AI devices.

Machine learning is a type of AI that allows computers to be trained by example data to make predictions for new instances. For example, a smart speaker algorithm like Alexa can learn to understand your voice commands, so it can understand you even when you ask for something for the first time. However, AI tends to require a great deal of electrical energy to train, which raises concerns about adding to climate change.

Now, scientists from the Institute of Industrial Science at The University of Tokyo have developed a novel design for stacking resistive random-access memory modules with oxide semiconductor (IGZO) access transistor in a three-dimensional spiral. Having on-chip nonvolatile memory placed close to the processors makes the machine learning training process much faster and more energy-efficient. This is because electrical signals have a much shorter distance to travel compared with conventional computer hardware. Stacking multiple layers of circuits is a natural step, since training the algorithm often requires many operations to be run in parallel at the same time.

Clothing Made Of Mushrooms Might Just Be The Future — And It’s Actually Pretty Cool

If you don’t like mushrooms, it might be because you haven’t tried them yet in dress or jacket form. Believe it or not, mushrooms can now be fashioned into flexible leather-like clothing, purses, pants, and even durable furniture and building bricks for a cleaner, more sustainable planet. Phil Ross and his team at the San Francisco-based MycoWorks, a group of engineers, designers, and scientists, are developing products inspired by fungi’s lattice-like “roots,” called mycelium. According to the MycoWorks website, mycelium are carbon-negative and can also be naturally dyed any color, so your mushroom dress or house can be bright purple, fuchsia, or Cerulean blue if tan seems too subtle.

According to the website of Italy’s Mogu agency, which specializes in developing and scaling-up a range of mycelium-based technologies for the production of naturally-grown biomaterials and products, mushroom-based fabric can be tweaked to be as hard as enamel and shell-like or as soft and porous as a sponge, depending on the amount of light, humidity, exchange of gas, temperature, and types of “food” the mushroom is given (hemp, straw, etc.), rendering it as the ideal creative material for whatever you envision forging.

Researchers advance fuel cell technology

Posted by in categories: bioengineering, chemistry, energy, nanotechnology, sustainability, transportation

Washington State University researchers have made a key advance in solid oxide fuel cells (SOFCs) that could make the highly energy-efficient and low-polluting technology a more viable alternative to gasoline combustion engines for powering cars.

Led by Ph.D. graduate Qusay Bkour and Professor Su Ha in the Gene and Linda Voiland School of Chemical Engineering and Bioengineering, the researchers have developed a unique and inexpensive nanoparticle catalyst that allows the to convert logistic liquid fuels such as gasoline to electricity without stalling out during the electrochemical process. The research, featured in the journal, Applied Catalysis B: Environmental, could result in highly efficient gasoline-powered cars that produce low carbon dioxide emissions that contribute to global warming.

“People are very concerned about energy, the environment, and global warming,” said Bkour. “I’m very excited because we can have a solution to the energy problem that also reduces the emissions that cause global warming.”

Water vapor in the atmosphere may be prime renewable energy source

Posted by in categories: climatology, sustainability

The search for renewable energy sources, which include wind, solar, hydroelectric dams, geothermal, and biomass, has preoccupied scientists and policymakers alike, due to their enormous potential in the fight against climate change. A new Tel Aviv University study finds that water vapor in the atmosphere may serve as a potential renewable energy source in the future.

The research, led by Prof. Colin Price in collaboration with Prof. Hadas Saaroni and doctoral student Judi Lax, all of TAU’s Porter School of the Environment and Earth Sciences, is based on the discovery that materializes in the interaction between and . It was published in Scientific Reports on May 6, 2020.

“We sought to capitalize on a naturally occurring phenomenon: electricity from water,” explains Prof. Price. “Electricity in thunderstorms is generated only by water in its different phases— , water droplets, and ice. Twenty minutes of cloud development is how we get from water droplets to huge electric discharges—lightning—some half a mile in length.”

The World’s First Open-Source Nuclear Reactor Blueprint Is Coming Online

Posted by in categories: climatology, nuclear energy, sustainability

To advance his vision, last week EIC launched the OPEN100 project, which Kugelmass says will provide open-source blueprints for the design, construction, and financing of a 100-megawatt nuclear reactor. He claims the reactor can be built for $300 million in less than two years, significantly decreasing the per-kilowatt cost of nuclear power.

“Nuclear power isn’t just part of the solution to addressing climate change; it is the solution,” Kugelmass said in a press release. “OPEN100 will radically change the way we deploy nuclear power plants going forward, offering a substantially less expensive and less complicated solution.”

The logic behind the idea is that the biggest barrier to the widespread use of nuclear is the cost of building reactors, which most experts would agree is a major problem for the industry. Kugelmass thinks that’s because we’ve been focused on large, overly complicated reactors that take far too long to build. His solution is to go back to tried and tested pressurized water reactors from the previous century, and bring their cost down even further through standardization and a focus on speedy construction.
