Nextracker & BCI Steel Renovate Abandoned Pittsburgh Steel Factory to Serve Growing U.S. Utility-Scale Solar Market

Posted by in categories: solar power, sustainability

This is Nextracker’s third new factory, adding to the company’s new Texas and Arizona factories announced in April and May, towards building 10 GW of annual domestic solar tracker capacity. Courtesy of Nextracker — by Pallavi Singla.


Nextracker LLC, the global market leader in utility-scale solar trackers, and BCI Steel, a Pittsburgh-based steel fabricator, this week announced the reopening of the historic Bethlehem Steel manufacturing factory in nearby Leetsdale to produce solar tracker equipment for large-scale solar power plants.

The steel processing plant will incorporate both BCI Steel’s new and reshored equipment shipped to the U.S. from factories in Malaysia and Brazil. Solar tracker products produced at the factory will serve rapidly growing solar markets in Pennsylvania, Indiana, New York, and Ohio.

An off-grid Starlink user achieves ‘infinite WiFi’ with 300 watts of solar

Posted by in categories: internet, satellites, solar power, sustainability

SpaceX’s Starlink provided the fastest satellite internet in the world.

Starlink has been equally praised in recent months for helping civilians in Ukraine and criticized for making astronomical work harder to the point it might endanger humanity.

Cobalt Anti-MXenes as Promising Anode Materials for Sodium-Ion Batteries

Posted by in categories: sustainability, transportation

The current electric vehicle market is entirely dominated by lithium-ion batteries (LIBs). However, due to the limited and unequal distribution of LIB raw materials on earth, there is a continuous effort to design alternate storage devices. Among the alternatives to LIBs, sodium-ion batteries (NIBs) are at the forefront because sodium resources are ubiquitous worldwide and virtually inexhaustible. However, one of the major drawbacks of the NIBs is their low specific charge capacity. Since the specific charge capacity of a cell can be improved by increasing the specific charge capacity of the anode material, there is a constant effort to find suitable anode materials. Recent studies suggested that a cobalt-boride (CoB) anti-MXene material (a newly discovered two-dimensional material) can yield superior specific charge capacities for LIBs than traditional graphite-based anodes.

Team creates anode-free Na batteries with high energy densities and long cycle lifetimes

Posted by in categories: energy, sustainability

In recent years, engineers worldwide have been trying to devise new battery and energy storage technologies that are more sustainable and cost-effective. One of the solutions attracting particular interest is sodium-based battery technology.

Sodium-ion batteries could have numerous advantages over conventional and widely used lithium-based batteries. Most notably, as is abundant on our planet and can be easily sourced, they could be affordable and easy to produce on a large-scale.

Despite their possible advantages, most developed so far exhibited low energy densities, due to the relatively large atomic size of sodium and its considerable weight. Typically, these batteries exhibit energy densities below 160 Wh kg-1, which is significantly lower than that of .

Aquaculture drives aquatic food yields to new high

Posted by in categories: food, sustainability

The production of wild and farm-raised fish, shellfish and algae reached record levels in 2020, and future increases could be vital to fighting world hunger, the Food and Agriculture Organization said Wednesday.

Driven by sustained growth in aquaculture, and aquatic farming together hauled in 214 million tonnes, the UN agency said in a report.

The total first-sale value of 2020 production topped $400 million, with $265 million coming from aquaculture, a sector poised for further expansion.

Elon Musk acknowledges the advantage of Tesla ads

Posted by in categories: Elon Musk, sustainability, transportation

Elon Musk may be an oddball online, but he helped bring a lot of technology to the world. Happy Birthday Elon Musk! Here’s a Look on the Tech CEO’s Significance in the World.


Elon Musk talked about the advantages of Tesla ads in an interview with Tesla supporters, including the President of Tesla Owners Silicon Valley, the President of My Tesla Adventure, and the Kilowatts founder.

Musk noted that public support for Tesla is appreciated, and the Tesla community’s efforts to shoot down FUD (fear, uncertainty, and doubt) for the company have also been helpful. Musk has opposed the idea of Tesla ads in the past. However, during the interview, he acknowledged that Tesla ads might have some advantages.

Artificial photosynthesis can produce food without sunshine

Posted by in categories: bioengineering, biological, chemistry, food, solar power, sustainability

Photosynthesis has evolved in plants for millions of years to turn water, carbon dioxide, and the energy from sunlight into plant biomass and the foods we eat. This process, however, is very inefficient, with only about 1% of the energy found in sunlight ending up in the plant. Scientists at UC Riverside and the University of Delaware have found a way to bypass the need for biological photosynthesis altogether and create food independent of sunlight by using artificial photosynthesis.

The research, published in Nature Food, uses a two-step electrocatalytic process to convert , electricity, and water into acetate, the form of the main component of vinegar. Food-producing organisms then consume acetate in the dark to grow. Combined with to generate the electricity to power the electrocatalysis, this hybrid organic-inorganic system could increase the conversion efficiency of sunlight into , up to 18 times more efficient for some foods.

“With our approach we sought to identify a new way of producing food that could break through the limits normally imposed by biological photosynthesis,” said corresponding author Robert Jinkerson, a UC Riverside assistant professor of chemical and environmental engineering.

Our universe was made by aliens in a lab, theorises Harvard scientist

Posted by in categories: biological, climatology, genetics, habitats, quantum physics, sustainability

Ever considered the notion that everything around you was cooked up by aliens in a lab? Theoretical physicist and former chair of Harvard’s astronomy department, Abraham ‘Avi’ Loeb, has proposed a wild – if unsettling – theory that our universe was intentionally created by a more advanced class of lifeform.

In an op-ed for Scientific American, “Was Our Universe Created In A Laboratory?”, Loeb suggested that aliens could have created a ‘baby universe’ using ‘quantum tunneling’, which would explain our universe’s ‘flat geometry’ with zero net energy. If this discovery were proven true, then the universe humans live in would be shown to be “like a biological system that maintains the longevity of its genetic material through multiple generations,” Loeb wrote.

Loeb put forward the idea of a scale of developed civilisations (A, B, etc.) and, due to that fact that on Earth we currently don’t have the ability to reproduce the astrophysical conditions that led to our existence, “we are a low-level technological civilisation, graded class C on the cosmic scale” (essentially: dumb). We would be higher up, he added, if we possessed the ability to recreate the habitable conditions on our planet for when the sun will die. But, due to our tendency to “carelessly destroy the natural habitat” on Earth through climate change, we should really be downgraded to class D.

McMaster says AI can help beat adversaries, overcome ‘critical challenges’

Posted by in categories: policy, robotics/AI, security, sustainability

WASHINGTON — Artificial intelligence and related digital tools can help warn of natural disasters, combat global warming and fast-track humanitarian aid, according to retired Army Lt. Gen. H.R. McMaster, a onetime Trump administration national security adviser.

It can also help preempt fights, highlight incoming attacks and expose weaknesses the world over, he said May 17 at the Nexus 22 symposium.

The U.S. must “identify aggression early to deter it,” McMaster told attendees of the daylong event focused on autonomy, AI and the defense policy that underpins it. “This applies to our inability to deter conflict in Ukraine, but also the need to deter conflict in other areas, like Taiwan. And, of course, we have to be able to respond to it quickly and to maintain situational understanding, identify patterns of adversary and enemy activity, and perhaps more importantly, to anticipate pattern breaks.”
