Building a better supercomputer is something many tech companies, research outfits, and government agencies have been trying to do over the decades. There’s one physical constraint they’ve been unable to avoid, though: conducting electricity for supercomputing is expensive.

Not in an economic sense—although, yes, in an economic sense, too—but in terms of energy. The more electricity you conduct, the more resistance you create (electricians and physics majors, forgive me), which means more wasted energy in the form of heat and vibration. And you can’t let things get too hot, so you have to expend more energy to cool down your circuits.

Whoop Energy and XCel Power have ceased trading – affecting around 550 customers.

Consumers from both energy firms will be designated a new supplier by market regulator Ofgem – through its supplier of last resort process.

Whoop Energy (Whoop) provides gas and electricity to 262 customers, including 50 households (domestic consumers).

New applications in energy, defense and telecommunications could receive a boost after a team from The University of Texas at Austin created a new type of “nanocrystal gel”—a gel composed of tiny nanocrystals each 10,000 times smaller than the width of a human hair that are linked together into an organized network.

The crux of the team’s discovery is that this is easily tunable. That is, it can be switched between two different states by changing the temperature. This means the material can work as an , absorbing different frequencies of light depending on whether it’s in a gelled state or not. So, it could be used, for example, on the outside of buildings to control heating or cooling dynamically. This type of optical filter also has applications for defense, particularly for thermal camouflage.

The gels can be customized for these wide-ranging applications because both the nanocrystals and the molecular linkers that connect them into networks are designer components. Nanocrystals can be chemically tuned to be useful for routing communications through fiber optic networks or keep the temperature of space craft steady on remote planetary bodies. Linkers can be designed to cause gels to switch based on ambient temperature or detection of environmental toxins.

Award Helps Move Cost-Effective, Productive, Robust Wave Energy Design a Step Closer to Commercialization and Widespread Use

In 1974, Stephen Salter, a professor at the University of Edinburgh, sent his “ducks” into the Scottish seas, launching the world’s first major wave energy project. But the ocean’s rough heaves and surges proved too much for his house-sized, floating generators. Like the more recent Pelamis’ P-750 model and Aquamarine’s Oysters, they succumbed to the power they were meant to harness.

“We have to ask ourselves,” said Krish Thiagarajan Sharman, the endowed chair in renewable energy at the University of Massachusetts Amherst, “why have we been working on this for so long? Why don’t we have grid-ready, commercial-scale wave energy systems out in the world?”

Electronic components applied to implement IoT based smart farming systems, ranging from processors, sensors, signal conditioning, power management, connectivity, and positioning.

The IoT systems in smart farming have been depicted in six main sections by EET India, which are processors, sensors, signal conditioning, power management, connectivity, and positioning. Common use cases like automatic fertilization, automatic irrigation, crop management, precision farming, and livestock monitoring all can be realized through IoT systems. After sensors detect the environmental phenomena and target objects, the information will be transmitted to controlled processors through wireless connectivity. Then, the processors can collect and analyze these data, or even help farmers with further decision making.

Quaise Energy, a startup based in Cambridge, Massachusetts, has announced its intentions to revolutionize how conventional power plants produce electricity. They have developed a new type of drilling technology that they claim will allow virtually any power plant to convert to geothermal as a fuel source.

The new technology uses a gyrotron-powered that vaporizes a borehole by emitting millimeter-sized energy waves from the tip of a drill bit. Engineers at Quaise have been working to perfect the technology for the past decade. The energy waves pulverize the rock as the hole is dug, allowing for digging much deeper than conventional drills. The energy waves, notably, are generated on the surface—their frequency is near to that used by microwaves.

Once the hole is excavated, water can be pumped into its depths, where the heat from the Earth will convert it to steam that rises back up out of the hole like a geyser. Also, the well can be used indefinitely to produce electricity using a geothermal source of energy, making it cheaper to produce electricity than conventional methods.

Researchers from the Institute of High Energy Physics of the Chinese Academy of Sciences examined the validity of the theory of relativity with the highest accuracy in a study entitled “Exploring Lorentz Invariance Violation from Ultrahigh-Energy γRays Observed by LHAASO,” which was published in the latest issue of Physical Review Letters.

According to Einstein’s of relativity, the fastest speed of matter in the Universe is the speed of light. Whether that limit is breachable can be tested by examining Lorentz breaking or Lorentz invariance violation.

“Using the world’s highest energy gamma rays observed by the Large High Altitude Air-shower Observatory (LHAASO), a large-scale cosmic ray experiment in Daocheng, Sichuan province, China, we tested Lorentz symmetry. The result improves the breaking energy scale of Lorentz symmetry by dozens of times compared with the previous best result. This is the most rigorous test of a Lorentz symmetry breaking form, confirming once again the validity of Einstein’s relativistic space-time symmetry,” said Prof. Bi Xiaojun, one of the paper’s corresponding authors. Prof. BI is a scientist at the Institute of High Energy Physics and a member of the LHAASO collaboration.

In the quest for the perfect battery, scientists have two primary goals: create a device that can store a great deal of energy and do it safely. Many batteries contain liquid electrolytes, which are potentially flammable.

As a result, solid-state lithium-ion batteries, which consist of entirely solid components, have become increasingly attractive to scientists because they offer an enticing combination of higher safety and increased energy density—which is how much energy the battery can store for a given volume.

Researchers from the University of Waterloo, Canada, who are members of the Joint Center for Energy Storage Research (JCESR), headquartered at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, have discovered a new solid electrolyte that offers several important advantages.
