Millions of people could suddenly lose electricity if a ransomware attack just slightly tweaked energy flow onto the U.S. power grid.

No single power utility company has enough resources to protect the entire grid, but maybe all 3,000 of the grid’s utilities could fill in the most crucial gaps if there were a map showing where to prioritize their security investments.

Purdue University researchers have developed an to create that map. Using this tool, regulatory authorities or cyber insurance companies could establish a framework that guides the security investments of power utility companies to parts of the grid at greatest risk of causing a blackout if hacked.

Portland General Electric (PGE), a public utility, has partnered with NextEra Energy Resources to create a 350 megawatt (MW) clean energy project that combines wind, solar, and battery storage. Wheatridge Renewable Energy Facility, located at the northern edge of Oregon, has the capacity to serve 100,000 homes.

Although great progress is being made with scaling up renewables, intermittency remains a significant issue – since wind does not always blow, and the Sun does not always shine. Falling costs and improvements in technology mean that batteries are increasingly a realistic option for utilities, but we are still a long way from such systems being able to fully handle the demands of national electrical grids.

The newly operational Wheatfield facility is among the most notable advances in battery storage to date in the U.S. It consists of 120 turbines (a mix of 2.3 MW and 2.5 MW machines) generating 300 MW, alongside a 50 MW photovoltaic solar array, for a total of 350 MW. An accompanying battery storage facility is charged using power from the grid and provides 30 MW of continuous power for four hours, i.e. 120 megawatt-hours (MWh). When combined, this is enough to supply nearly 60% of the power generated by the Boardman Coal Plant, which became the last coal-fired plant in Oregon before its demolition a few weeks ago.

Tesla is finally planning to expand the Gigafactory Nevada building after years of being “stuck” at about “30% of its final size.”

Tesla Gigafactory Nevada was the first major step in Tesla’s effort to secure battery cell supply for its ambitious growth.

The automaker partnered with Panasonic to deploy new battery cell production capacity at the facility, and Tesla used those cells to build battery packs for its vehicles and energy storage products.

Desalination plants discharge brine and wastewater, which can also kill nearby aquatic life if the process is not done properly. And generating the large quantity of energy that the plants consume has its own environmental impacts until it can be done carbon-free, which is still years off in most cases.

Unaffordable Water From Costly Plants

Cost is another major hurdle. In most areas, the cost of ocean desalination is projected to remain considerably higher than the cost of feasible alternatives such as conservation for the next several decades, the timeline that utilities use when planning new investments. My colleagues and I found this in our research comparing water supply alternatives for Huntington Beach, even though we made favorable assumptions about ocean desalination costs.

LAS CRUCES, N.M., May 16, 2022 /PRNewswire/ — In four weeks of continuous live-fire exercises, an industry team led by Raytheon Intelligence & Space, a Raytheon Technologies (NYSE: RTX) business, and Kord, a wholly owned subsidiary of KBR, defeated multiple 60mm mortar rounds with a 50kW-class high energy laser integrated on a Stryker combat vehicle.

The directed energy weapon system — part of the U.S. Army’s Directed Energy Maneuver-Short Range Air Defense, or DE M-SHORAD — acquired, tracked, targeted and defeated multiple mortars and successfully accomplished multiple tests simulating real-world scenarios.

Continuing to put the DE M-SHORAD system to the test, the recent operational assessment at White Sands Missile Range also included defeating several small, medium and large drones.

Capturing combustion on a large scale is now possible.

The first cross-sectional photos of carbon dioxide in a jet engine exhaust plume were taken by researchers using brand-new near-infrared light imaging technology.

The research was published in Applied Optics’ 28th issue.

Regent has released video of its remarkable Seaglider prototype in flight testing. The first machine to combine the efficiency advantages of ground effect and hydrofoiling in a single design, it promises revolutionary speed and range in coastal areas.

Wing-in-ground effect (WIG) aircraft such as the Soviet-era Ekranoplan have shown promise in the past, but they’re yet to take off, so to speak, as a mainstream form of transport. These low-flying birds ride on a cushion of air between their wings and the surface, which gives them a significant lift and efficiency boost over regular planes flying higher in the air – as long as they stay within their own wingspan of the surface beneath. This extreme altitude restriction means that while ground-effect aircraft could fly over land, it’s too dangerous for regular operations, and they typically stay over water.

The numbers haven’t been attractive enough to date, but the era of electrification brings a set of new incentives to the game. Electric boats are struggling to prove their worth; batteries simply don’t hold enough energy to push through the tough medium of water for long distances. Early electric aircraft struggle to deliver useful range with a decent number of passengers on board, too. Regent looked at this, and saw a situation where the efficiency of the old ground-effect vehicle could give it a genuine commercial advantage, if paired with another, more recent technology.

The 100 MW Dalian Flow Battery Energy Storage Peak-shaving Power Station, with the largest power and capacity in the world so far, was connected to the grid in Dalian, China, on September 29, and it will be put into operation in mid-October.

This energy storage project is supported technically by Prof. Li Xianfeng’s group from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences. And the system was built and integrated by Rongke Power Co. Ltd.

The Dalian Flow Battery Energy Storage Peak-shaving Power Station was approved by the Chinese National Energy Administration in April 2016. As the first national, large-scale storage demonstration project approved, it will eventually produce 200 megawatts (MW)/800 megawatt-hours (MWh) of electricity.

Bjarke Ingels Group and Barcode Architects collaborated to create ‘Sluishuis’ – an angular residential complex placed above the IJ Lake in Amsterdam. The structure’s sharp geometric ends meet in the air, water, and land, creating a mesmerizing structure that seems to be jutting into the sky while resembling the bow of a ship! It is constructed on an artificial island in the IJ Lake and forms a geometrically-intriguing gateway from the lake.

In the future, many computers will most likely be based on electronic circuits made of superconductors. These are materials through which an electrical current can flow without energy losses, could be very promising for the development of high-performance supercomputers and quantum computers.

Researchers at University of California Santa Barbara, Raytheon BBN Technologies, University of Cagliari, Microsoft Research, and the Tokyo Institute of Technology have recently developed a magneto-optic modulator—a device that control the properties of a light beam through a . This device, introduced in a paper published in Nature Electronics, could contribute to the implementation of large-scale electronics and computers based on superconductors.

“We are working on a new technology that can speed up high-performance supercomputers and quantum computers based on superconductor technology,” Paolo Pintus, the researcher who led the study, told TechXplore. “Superconductors work properly only at low temperatures, generally just above absolute zero (−273.15° Celsius). Because of this, circuits made of these materials must be kept inside a dedicated refrigerator.”
