Tesla to provide Virtual Power Plant (VPP) services to Texas grid

Posted by in categories: energy, sustainability

A recent press release from the Public Utility Commission of Texas (PUCT) has revealed that Tesla will be providing Virtual Power Plant (VPP) services to the state’s grid. The program is part of the Aggregate Distributed Energy Resource (ADER) project that the PUCT pushed last year.

With the VPP in place, Texas could now evaluate how consumer-owned small energy devices, such as home battery units, can be virtually aggregated to provide grid-scale services. Similar programs have been launched by Tesla in California and Australia, to much success.

As per the PUCT’s press release, the two ADERs that are launching the initiative involve Tesla Electric customers who have Powerwall batteries in their homes. The participants of the program have agreed to sell their surplus power in the ERCOT market, and will be compensated for doing so. One ADER is comprised of Houston-area CenterPoint Energy customers, while the other is comprised of Dallas-area customers served by Oncor Electric Delivery Company.

A $10k satellite built by students can help clean space junk

Posted by in categories: satellites, sustainability

SBUDNIC was a small cube satellite, about the size of a bread loaf, that was launched on a SpaceX rocket in May 2022.

Space junk is a serious issue that threatens the safety and sustainability of orbital activities. To address this problem, a team of students from Brown University designed and built a low-cost cube satellite that successfully deorbited itself after completing its mission. The satellite, named SBUDNIC, used a simple plastic drag sail to increase its atmospheric drag and hasten its reentry.

As per the press release, the small cube satellite has burned up high above Turkey after 445 days in orbit. Its reentry into Earth’s atmosphere on Tuesday, Aug. 8, marked the successful conclusion of a low-cost experiment aimed at reducing space debris, five years ahead of schedule.

Meyers Manx 2.0 Electric Buggy Pricing Announced, Starts At $74,000

Posted by in categories: sustainability, transportation

Meyers Manx, the original maker of the Volkswagen Beetle-based, fiberglass-bodied beach buggy from the 1960s, just published the starting price for its all-new, all-electric Manx 2.0 electric buggy, and it’s not exactly cheap.

Revealed last year at The Quail, A Motorsports Gathering, the company’s first all-new vehicle in nearly 20 years starts at $74,000 for the base variant with the 20-kilowatt-hour battery pack and yet-to-be-released performance figures. That’s almost as expensive as the recently introduced Tesla Model S Standard Range, which starts at $78,490 and offers a 320-mile range.

The base MSRP came with no extra information and was casually thrown in a sentence at the end of the press release for the company’s new Resorter Neighborhood Electric Vehicle (NEV), which debuted last week at The Quail, so we still don’t know how much the top-of-the-line model will set prospective customers back.

This Universal Charger Could Charge Any Electric Vehicle

Posted by in categories: sustainability, transportation

In a recent advance, researchers have created a novel battery charger that can support present and future generations of battery packs for EVs across a vast range of voltages: anything between 120 and 900 volts. The new tech is described in a study published in the September edition of theIEEE Transactions on Power Electronics.


These next-generation batteries will bring shorter charging times while also weighing less, which means that EVs can be ready to drive sooner and travel farther on a full charge. “However, charging these high-voltage batteries with existing chargers degrades the efficiency, due to operating at twice the rated voltage,” says Deepak Ronanki, an assistant professor at the Indian Institute of Technology Madras, in Chennai, India, and an IEEE senior member who was involved in the study.

Ronanki and doctoral research scholar Harish Karneddi created a universal charger capable of supporting voltages between 120 and 900 V—something they say had not yet otherwise been achieved.

New system captures fog and turns it into clean water

Posted by in categories: chemistry, particle physics, solar power, sustainability

People living in dry but foggy areas can benefit from this technology.

Researchers from ETH Zurich have developed a system that captures fog in the atmosphere and simultaneously removes contaminants while running using solar power.

The harvesting and water treatment system consists of a metal wire mesh with a solar-light-activated reactive coating that captures the fog. The droplets of water then trickle down into a container below. The mesh is coated with a mixture of specially selected polymers and titanium dioxide, which acts as a chemical catalyst and breaks down the molecules of the pollutants into harmless particles.

Powering Ahead: Nobel-Winning Chemistry Unleashes Next-Generation Energy Storage Devices

Posted by in categories: chemistry, energy, sustainability, transportation

Flexible polymers made with a new generation of the Nobel-winning “click chemistry” reaction find use in capacitors and other applications.

Society’s increasing demand for high-voltage electrical technologies – including pulsed power systems, cars, electrified aircraft, and renewable energy applications – requires a new generation of capacitors that store and deliver large amounts of energy under intense thermal and electrical conditions.

A new polymer-based device that efficiently handles record amounts of energy while withstanding extreme temperatures and electric fields has now been developed by researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and Scripps Research. The device is composed of materials synthesized via a next-generation version of the chemical reaction for which three scientists won the 2022 Nobel Prize in Chemistry.

Making big leaps in understanding nanoscale gaps

Posted by in categories: chemistry, nanotechnology, physics, solar power, sustainability

Creating novel materials by combining layers with unique, beneficial properties seems like a fairly intuitive process—stack up the materials and stack up the benefits. This isn’t always the case, however. Not every material will allow energy to travel through it the same way, making the benefits of one material come at the cost of another.

Using cutting-edge tools, scientists at the Center for Functional Nanomaterials (CFN), a U.S. Department of Energy (DOE) User Facility at Brookhaven National Laboratory, and the Institute of Experimental Physics at the University of Warsaw have created a new layered structure with 2D materials that exhibits a unique transfer of energy and charge. Understanding its may lead to advancements in technologies such as solar cells and other optoelectronic devices. The results were published in the journal Nano Letters.

Transition metal dichalcogenides (TMDs) are a class of materials structured like sandwiches with . The meat of a TMD is a , which can form with electrons on their outermost orbit or shell, like most elements, as well as the next shell. That metal is sandwiched between two layers of chalcogens, a category of elements that contains oxygen, sulfur, and selenium.

How “Smart Rust” Nanoparticles Are Revolutionizing Water Cleanup

Posted by in categories: nanotechnology, particle physics, sustainability

Researchers have developed “smart rust,” iron oxide nanoparticles that clean water by attracting pollutants such as oil, nano-and microplastics, glyphosate, and even estrogen hormones.

Pouring flecks of rust into water typically makes it dirtier. However, a groundbreaking development by researchers has led to the creation of “smart rust,” a type of iron oxide nanoparticle that can purify water. This smart rust has the unique ability to attract various pollutants, such as oil, nano-and microplastics, and the herbicide glyphosate, depending on the particles’ coating. What makes it even more efficient is its magnetic nature, which allows easy removal from water using a magnet, taking the pollutants along with it. Recently, the team has optimized these particles to capture estrogen hormones, which can be detrimental to aquatic life.
