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.

Scientists discover new plants that could lead to ‘climate-proof’ chocolate

Posted by in categories: climatology, economics, sustainability

Scientists have found three new species that are close relatives to the plant from which chocolate is produced—a discovery that could pave the way for climate-proof chocolate. The team’s research has been published in the journal Kew Bulletin.

The , discovered in the rain forests of South America, are closely related to Theobroma cacao, the tree that bears which are of tremendous economic importance.

The research team comprising scientists from University College Cork (UCC), the University of São Paulo and New York Botanical Garden say their finding is significant as it indicates that there is much work still to be done in characterizing Earth’s biodiversity.

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.

Giant Clams Are Models of Solar-Energy Efficiency

Posted by in categories: food, solar power, sustainability

A theoretical model for the illumination of photosynthesizing algae in giant clams suggests principles for high efficiency collection of sunlight.

Crops on a farm capture only about 3% of the available solar energy, much less than the 20%–25% captured by large solar arrays. Now a research team has used a theoretical model to explain efficiencies as high as 67% for photosynthesizing algae hosted by giant clams [1]. The researchers argue that clams achieve this performance with an optimized geometry. The mollusks may also adjust the algae clusters’ spacing according to changing light conditions. The researchers hope that an understanding of clams’ solar efficiency might help other scientists improve the efficiency of solar technology and explain aspects of the photosynthetic behavior of other ecosystems such as forests.

A photosynthetic cell can convert nearly every incoming photon to usable energy, says biophysicist Alison Sweeney of Yale University. But efficiency is much lower in larger systems such as agricultural fields. “Can we achieve near-perfect efficiencies over large land areas? This is an urgent question” as researchers try to reduce reliance on fossil fuels, Sweeney says.

Solar Power Investment Will Overtake Oil for the First Time Ever This Year

Posted by in categories: biotech/medical, climatology, nuclear energy, sustainability

Year 2023 Basically solar will last several billion years and make type 0 civilization resources obsolete by making trillions of dollars in profits with nearly zero emissions.


Between the Covid-19 pandemic, the Ukraine conflict, inflation, and the renewables transition, the 2020s have been a volatile decade for energy. The pandemic reduced demand for electricity and oil all over the world, causing prices to plummet. Then the Ukraine invasion brought sanctions on Russian oil and gas, pushing energy prices up and leaving European countries scrambling (particularly for natural gas). High energy prices have since contributed to inflation, and in many places utility costs are far surpassing inflation. All the while, worry over climate change has continued to mount, with calls to reduce our dependence on fossil fuels growing ever louder.

In short, the energy situation in the US and around the world is a mess. But the International Energy Agency released some good news in its recent World Energy Investment report. The report is compiled annually, and the 2023 version came out at the end of May. For the first time ever, it found that investment in renewables—specifically solar power—will overtake spending on oil.
