With less than three weeks until the R2 is finally unveiled, Rivian (RIVN) confirmed it will bring the more affordable electric SUV to Europe.
After opening the R2 website last week, Rivian gave us our first look at the new EV during a teaser video.
The shadowy image shows a smaller-looking version of the R1S, aligning with what we’ve seen in the past. A patent filed by Rivian last month showed a more compact electric SUV with slightly smaller headlights and a rear quarter panel.
UCLA spinout Equatic has developed a carbon removal technology it believes can help the world meet its climate change goals — by converting CO2 in the ocean into seashell dust.
The challenge: To prevent the worst predicted effects of climate change, experts say we need to not only slash our carbon emissions, but also remove and permanently store some of the CO2 that’s already been released.
The ocean does this naturally: it already absorbs about 31% of human-made carbon emissions, but there’s a limit to the amount of CO2 that seawater can absorb before it starts to release the carbon back into the atmosphere. Absorbing CO2 from the air also causes ocean acidification, resulting in further environmental damage.
The Cactus ransomware gang claims they stole 1.5TB of data from Schneider Electric after breaching the company’s network last month.
25MB of allegedly stolen were also leaked on the operation’s dark web leak site today as proof of the threat actor’s claims, together with snapshots showing several American citizens’ passports and non-disclosure agreement document scans.
As BleepingComputer first reported, the ransomware group gained access to the energy management and automation giant’s Sustainability Business division on January 17th.
Sun Bear, an enormous solar and battery storage installation in the Four Corners region of Colorado, will have more than two million solar panels spread across 5,500 acres of land belonging to the Ute Mountain Ute Tribe, part of the Weenuche Band of the Ute Nation. The primary developer is the Canigou Group, which styles itself as a global leader in renewable energy. “We are active throughout Europe, Australia and North America where we work with partners at the local level to provide a holistic solution,” it says on its website. The Sun Bear facility will cost up to $1.5 billion and produce peak power of 975 MW. There is no information currently available about the size of the battery storage system or who will supply the batteries for it.
There are several reasons why the site in southwest Colorado, which borders New Mexico, Arizona, and Utah, was chosen for this large scale solar project. Carigou Group says “Sun Bear is well positioned for harnessing the sun with its large unobstructed sky, high annual solar irradiance, and low seasonal variability. The site is located close to a confluence of transmission systems which provide access to customers via both transmission and distribution interconnection.”
Inspired by the distribution of sunflower seeds, a group of scientists say they have developed a new city-pattern that ensures the best distribution of solar energy utilization “in low solar radiation countries.”
“Our new city-plan bears close resemblance to the distribution of seeds in sunflowers. This distribution ensures the best utilization of solar energy,” says Dr. Ammar A. T. Alkhalidi, University of Sharjah’s Associate Professor of Sustainable and Renewable Energy Engineering.
Dr. Alkhalidi is the lead author of a new study titled “Sunflower-inspired urban city pattern to improve solar energy utilization in low solar radiation countries.” The study is published in journal Renewable Energy Focus.
Sandia National Laboratories researchers have developed a fundamentally new type of rotary electrical contact. The technology is called Twistact, and it will eliminate the need for expensive rare-earth magnets in large wind turbines.
Sandia is now ready to partner with the energy industry to develop the next generation of direct-drive wind turbines.
Sandia’s Twistact is a novel approach to transmitting electrical current between a stationary and rotating frame, or between two rotating assemblies having different speeds or rotational directions. This method is ideal for use in wind turbines.
Odysseus is one of the first landers to participate in NASA’s Commercial Lunar Payload Services (CLPS) program, which aims to deliver science and technology payloads to the lunar surface using commercial partners. The CLPS program is a key component of NASA’s Artemis program, which plans to establish a sustainable human presence on the moon by the end of the 2020s.
Intuitive Machines successfully transmitted its first IM-1 mission images to Earth on February 16, 2024. The images were captured shortly after separation from @SpaceX’s second stage on Intuitive Machines’ first journey to the Moon under @NASA’s CLPS initiative. pic.twitter.com/9LccL6q5tF — Intuitive Machines (@Int_Machines) February 17, 2024
Odysseus is carrying six NASA experiments and technology demonstrations, along with six private payloads, on its current IM-1 mission. The lander is expected to touch the moon on February 22, near the lunar equator.
Researchers from Ohio State University have developed an innovative method to capture carbon dioxide (CO2) directly from the atmosphere. Powered by geothermal energy, the team’s method poses a climate-friendly alternative to traditional carbon capture technologies. It highlights the synergy between Direct Air Carbon Dioxide Capture (DACC) technologies and renewable energies from beneath the Earth’s surface.
The approach, named Direct Air CO2 Capture with CO2 Utilization and Storage (DACCUS), promises a significant decrease in atmospheric CO2 levels, a major contributor to global warming.
Climate change primarily results from increased CO2 levels in the Earth’s atmosphere, largely due to human activities like burning fossil fuels for heat, electricity, and transportation.
In this study, a novel rapid diagnostic method was developed for optimizing the production of transplutonium isotope through high flux reactor irradiation. The proposed method was based on the concept of “Single Energy Interval Value (SEIV)” and “Energy Spectrum Total Value (ESTV)”, which significantly improved the production efficiency of isotopes such as 252Cf (by 15.08 times), 244Cm (by 65.20 times), 242Cm (by 11.98 times), and 238Pu (by 7.41 times). As a promising alternative to the traditional Monte Carlo burnup calculation method, this method offers a more efficient approach to evaluate radiation schemes and optimize the design parameters. The research discovery provides a theoretical basis for further refining the analysis of transplutonium isotope production, leading to more efficient and sustainable production methods. Future studies could focus on the implementation of energy spectrum conversion technology to further improve the optimal energy spectrum.
The production of transplutonium isotope, which are essential in numerous fields such as military and space technology, remains inefficient despite being produced through irradiation in a high flux reactor. Past studies on the optimization of transplutonium isotope production through irradiation in a high flux reactor have been limited by the computational complexity of traditional methods such as Monte Carlo burnup calculation. These limitations have hindered the refinement of the evaluation, screening, and optimization of the irradiation schemes. Hence, this research aimed to develop a rapid diagnostic method for evaluating radiation schemes that can improve the production efficiency of isotopes such as 252Cf, 244Cm, 242Cm, and 238Pu. The outcome of the study showed great potential in advancing the production of transplutonium isotope, which have numerous applications in fields such as military, energy, and space technology.
