Tesla Giga Berlin expansion gets approval from authorities: report

Posted by in categories: sustainability, transportation

Recent reports have noted that Tesla Germany has received permission to expand Giga Berlin from the Brandenburg State Office for the Environment, as per the Ministry of the Environment. With the approval in place, Tesla could start construction work ahead of schedule.

The Ministry of the Environment noted that the early start of construction involves the buildout of an asphalted logistics area for new vehicles, the construction of underground lines and staircases at the press shop, and the installation of rooftop solar panels. As per German publication Stern, Chancellor Olaf Scholz (SPD) has expressed his support for the Tesla Model Y factory’s expansion.

The approval for Giga Berlin’s expansion is expected to pave the way for the facility to increase its vehicle production output. It should be noted, however, that the approval that Tesla Germany was able to secure was only for expansion of the existing Giga Berlin facility. Further forest clearing activities, which are required for Tesla’s plan to build a railway station in the complex, still require permissions.

Posted by in categories: climatology, satellites, sustainability

New research has unraveled the complex dynamics of the planetary boundary layer, enhancing satellite detection of atmospheric pollutants and aiding environmental management and climate modeling efforts.

A new study has provided groundbreaking insights into Earth’s planetary boundary layer (PBL), a crucial area that affects air quality and climate. By analyzing satellite data, researchers have explored how the temperature gradient from the surface to the atmosphere impacts the identification of atmospheric pollutants, offering a deeper understanding of atmospheric thermal contrasts (TC).

The endeavor to keep tabs on and curb air pollution has been stymied by the enigmatic nature of the planetary boundary layer (PBL). This atmospheric strip, in constant caresses with the Earth’s surface, is a hotbed for pollutants. Yet, its mercurial dance through time and across geographies presents a formidable scientific puzzle. Given these hurdles, an in-depth dissection of the thermal contrast (TC) that delineates this layer is imperative.

Shining a light on oil fields to make them more sustainable

Posted by in categories: electronics, sustainability

One of the most common problems is spills of the salty brine that’s a toxic byproduct of pumping oil. Another is over-or under-pumping that can lead to machine failure and methane leaks. (The oil and gas industry is the largest industrial emitter of methane in the U.S.) Then there are extreme weather events, which range from winter frosts to blazing heat, that can put equipment out of commission for months. One of the wildest problems Sebastien Mannai SM ’14, PhD ’18 has encountered are hogs that pop open oil tanks with their snouts to enjoy on-demand oil baths.

Mannai helps oil field owners detect and respond to these problems while optimizing the operation of their machinery to prevent the issues from occurring in the first place. He is the founder and CEO of Amplified Industries, a company selling oil field monitoring and control tools that help make the industry more efficient and sustainable.

Amplified Industries’ sensors and analytics give oil well operators real-time alerts when things go wrong, allowing them to respond to issues before they become disasters.

Tesla Model Y tops Sweden auto registrations in the first half of 2024

Posted by in categories: climatology, life extension, sustainability

The Tesla Model Y has topped Sweden’s automotive registrations regardless of powertrain type in the first half of 2024, as shown in new data.

The Model Y was the most-registered vehicle in Sweden in the first six months of this year, according to data from Mobility Sweden reported by Carup on Monday. The Model Y topped the charts overall with 7,386 units registered, despite a 20 percent decline in overall EV sales. The Model 3 landed 14th overall in the six-month period, while electric options from Volvo, Toyota, Polestar, and Volkswagen were also some of the most registered.

“It is gratifying that the proportion of electric cars reached the best for the year in June, but at the same time we see a stagnant market, which leads to a gradually aging vehicle fleet,” said Mattias Bergman, CEO of Mobility Sweden. “In order to meet the climate goals and strengthen Sweden’s competitiveness, it is crucial that electrification is accelerated.”

Permaculture found to be a sustainable alternative to conventional agriculture

Posted by in categories: climatology, existential risks, sustainability

RPTU University of Kaiserslautern-Landau has shown for the first time, in a joint study with BOKU University, that permaculture brings about a significant improvement in biodiversity, soil quality and carbon storage.

In view of the challenges of climate change and species extinction, this type of proved to be a real alternative to conventional cultivation—and reconcile and .

Permaculture uses natural cycles and ecosystems as blueprint. Food is produced in an agricultural ecosystem that is as self-regulating, natural and diverse as possible. For example, is integrated into the cultivation of crops or the diversity of beneficial organisms is promoted in order to avoid the use of mineral fertilizers or pesticides.

Optoelectronics gain spin control from chiral perovskites and III–V semiconductors

Posted by in categories: computing, solar power, sustainability

A research effort led by scientists at the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL) has made advances that could enable a broader range of currently unimagined optoelectronic devices.

The researchers, whose previous innovation included incorporating a perovskite layer that allowed the creation of a new type of polarized (LED) that emits spin-controlled photons at room temperature without the use of magnetic fields or ferromagnetic contacts, now have gone a step further by integrating a III-V semiconductor optoelectronic structure with a chiral halide perovskite semiconductor.

That is, they transformed an existing commercialized LED into one that also controls the spin of electrons. The results provide a pathway toward transforming modern optoelectronics, a field that relies on the control of light and encompasses LEDs, solar cells, and telecommunications lasers, among other devices.
