Making Electricity Cheaper: A Cellphone-Sized Device Automatically Adjusts a Home’s Power Use to Save Money

Posted by in categories: climatology, economics, mobile phones, sustainability

A cellphone-sized device automatically adjusts a home’s power use up or down to save the consumer money and increase the resiliency of the electric grid.

The effects of climate change are pushing electrical grids around the world to their limits. Last year, unprecedented cold weather caused people in Texas to turn up their thermostats, which overwhelmed the power grid and caused days-long power outages. And in California, the power is turned off before there is a high possibility of a fire.

To combat the electric grid’s vulnerabilities and cut down on the use of non-renewable sources of energy, researchers at the Department of Energy’s SLAC National Accelerator Laboratory have developed technology that automatically adjusts a home’s power use up or down in response to fluctuating prices that are established by real-time market demand.

Scientists Discover a Massive Groundwater System in Sediments Below Antarctic Ice

Posted by in categories: climatology, sustainability

Many researchers believe that liquid water is a key to understanding the behavior of the frozen form found in glaciers. Meltwater is known to lubricate their gravelly bases and speed up their march toward the sea. In recent years, scientists in Antarctica have discovered hundreds of interconnected liquid lakes and rivers cradled within the ice itself. And, they have imaged thick basins of sediments under the ice, potentially containing the biggest water reservoirs of all. But so far, no one has confirmed the presence of large amounts of liquid water in below-ice sediments, nor investigated how it might interact with the ice.

Now, a research team has for the first time mapped a huge, actively circulating groundwater system in deep sediments in West Antarctica. They say such systems, probably common in Antarctica, may have as-yet unknown implications for how the frozen continent reacts to, or possibly even contributes to, climate change. The research was published in the journal Science on May 5, 2022.

Rechargeable Molten Salt Battery Freezes Energy in Place for Long-Term Storage

Posted by in categories: climatology, materials

Creating a battery that can withstand repeated cycles of heating and cooling is no small feat. Temperature fluctuations cause the battery to expand and contract, and the researchers had to identify resilient materials that could tolerate these changes. “What we’ve seen before is a lot of active research to make sure you do not have to go through that thermal cycle,” says Vince Sprenkle, a strategic advisor in energy storage at PNNL and a co-author of the new paper. “We’re saying, ‘We want to go through it, and we want to be able to survive and use that as a key feature.’”

The result is a rechargeable battery made from relatively inexpensive materials that can store energy for extended periods. “It’s a great example of a promising long-duration energy-storage technology,” says Aurora Edington, policy director of the electricity industry association GridWise Alliance, who was not involved with this research. “I think we need to support those efforts and see how far we can take them to commercialization.”

The technology could be particularly useful in a place such as Alaska, where near-constant summer sunlight coincides with relatively low rates of energy use. A battery that can store energy for months could allow abundant summer solar power to fulfill winter electricity needs. “What is so attractive about the freeze-thaw battery is that seasonal shifting capability,” says Rob Roys, chief innovation officer at Launch Alaska, a nonprofit organization that works to accelerate the deployment of climate technologies in the state. Roys hopes to pilot the PNNL battery in a remote part of his state.

Army of seed-firing drones will plant 100 million trees by 2024

Posted by in categories: climatology, drones, sustainability

That’s 25 times faster, at 80 percent the cost of conventional means.

Combating climate change and biodiversity loss is a complicated matter, causing prolonged and perhaps tedious conversations. But what if there was a cooler way to achieve all that?

Enter Australian start-up AirSeed Technology and their swarms of seed-firing drones that are planting 40,000 trees a day to fight deforestation. The company and its incredible technology were featured Wednesday on * Euro Green News*. drone that can plant 40,000 trees a day could be essential in fighting deforestation.

Gaia-Based Theosophy: Conception and Birth of the Living Earth

Posted by in categories: biological, climatology, evolution, neuroscience, sustainability

“The Earth has entered a radically new era, understood by scientists as the Anthropocene: a time when humanity reckons with massive geologic and biospheric forces we, as anthropos, have set in motion. The agency of Nature and the reality of humanity as a collective geologic force is becoming understood differently, even within the Western paradigm. It is a new world our children will inherit, for if humanity is to survive, we must come into new realizations of our place within the planetary life-support systems. To lay a path for future generations through the evolutionary steps that humanity must now take to learn to live in balance with the planet, science must come to balance with Spirit.” ―Oberon Zell, GaeaGenesis.

In the early 1970s, celebrated philosopher and mystic Oberon Zell was the first to propose the radical idea that the biosphere of Earth was a single living superorganism. His initial article on the subject electrified the emerging modern movement of Earth-based spirituality, generating volumes of correspondence, lecture tours, and further articles in various journals and books.

‘Tornado of Fire’ Is Latest Sight on the Sun’s Tumultuous Surface

Posted by in category: climatology

The sun is moving into the hyperactive phase of its roughly 11-year cycle when sunspots, solar flares and all other sorts of tumultuous heliocentric happenings become more common. Case in point: A vortex of fire as tall as 10 Earths stacked on top of each other could be seen doing a quick dance on the sun’s surface late Tuesday.

NASA’s Solar Dynamics Observatory caught an eruption from the sun that swirled like a tornado as it produced a bright coronal mass ejection, or CME. Astronomer Tony Phillips clipped the below footage for

CMEs are blasts of charged plasma that often accompany solar flares. When they’re directed at Earth, they can produce bright auroras when they collide with our magnetosphere. This particular CME that started with the rare solar twister was not directed at Earth.

Recycled glass waste used as sand replacement in 3D printing

Posted by in categories: 3D printing, climatology, sustainability

Researchers from Nanyang Technological University, Singapore (NTU Singapore) have developed the capability to use recycled glass in 3D printing, opening doors to a more environmentally sustainable way of building and construction.

Glass is one material that can be 100% recycled with no reduction in quality, yet it is one of the least recycled waste types. Glass is made up of silicon dioxide, or silica, which is a major component of sand, and therefore it offers significant untapped potential to be recycled into other products.

At the same time, due to growing populations, urbanization and , the world is facing a shortage of sand, with calling it one of the greatest sustainability challenges of the 21st century.

Survey: Trust in science is high, but misinformation is a threat

Posted by in categories: climatology, health, science, sustainability

Trust in science is rising worldwide, according to a 3M-backed survey released Tuesday, and more people expect it to solve the world’s problems.

But the fifth annual 3M State of Science Index also showed many are worried that misinformation could lead to more , greater societal divisions and lack of action on climate change.

“It’s really good to see that trust in is high, and that’s true in America and around the world, but misinformation threatens scientific credibility,” Jayshree Seth, 3M’s corporate scientist and chief science advocate, said in an interview. “It’s not simply a matter of communicating facts, data and evidence. We need to build that relationship with the public.”
