NOVEL MATERIAL CAPABLE OF 190% QUANTUM EFFICIENCY COULD REVOLUTIONIZE SOLAR POWER SYSTEMS

A new material capable of greatly improving the efficiency of solar power systems reportedly raised the quantum efficiency of solar panels to an unprecedented 190% during recent tests.

A prototype was developed by researchers with Lehigh University with funding from the U.S. Department of Energy, which features an active layer in a solar cell using the material that reportedly also achieved an average photovoltaic absorption of close to 80%.

Photovoltaic (PV) systems are electric systems that can provide usable solar power, usually involving solar panels that collect sunlight and convert it into electricity. Additional components include a solar inverter used to convert the power output into alternating current that can be used to power conventional devices.

Traditional solar cells possess a maximum external quantum efficiency (EQE) of 100%, which means they can generate and collect a single electron for each photon they absorb through sunlight collected. In recent years, advancements in materials used for such systems have shown promise for increased generation and collection of electrons from high-energy photons.

The efficiency displayed by the new prototype tested by the Lehigh University team far exceeds the current theoretical limits for conventional silicon-based materials used in such PV systems and could potentially revolutionize the field involving the quantum materials they rely on.

Chinedu Ekuma, a physics professor specializing in computational condensed matter physics, says experiments with the new material mark a significant leap toward the development of novel energy solutions that are both more sustainable and accessible.

Ekuma and the team behind the discovery attribute the new material’s remarkable capabilities to what the refer to as “intermediate band states,” which involve certain energy levels that are built into the material’s electronic structure, helping to optimize their ability to convert solar energy.

Illegal Alien Tries to Rob Bank in Ohio Using a Translator App Because He Couldn’t Figure Out How to Say “Put the Money in the Bag”

In a bizarre twist to bank robbery attempts, an alleged illegal immigrant tried to rob a bank in Sandusky, Ohio using a translator app on his phone to demand money from the tellers.

The suspect, identified as 20-year-old Yeixon Brito-Gonzalez from Venezuela, found himself in the grips of the law shortly after his failed attempt.

The incident happened on April 4, when local police were alerted to a suspicious individual inside a bank who was attempting to communicate with the tellers via his phone, without speaking, FOX 8 reported.

According to Sandusky Police Chief Jared Oliver, the security footage from the bank clearly showed Brito-Gonzalez using the translator app to convey messages such as “get the money” and “put the money in the bag” to the bank staff.

Despite his efforts, the tellers did not comply with his demands, leading Brito-Gonzalez to leave the premises empty-handed. His departure from the scene was short-lived, however, as Sandusky officers apprehended him nearby shortly after the incident.

DARPA’s Defiant Fully Uncrewed Demonstrator Ship Will Hit The Seas Later This Year

Plans to test a new uncrewed surface vessel are making waves, with the company heading the project targeting the end of this year to put its demonstrator in the water. Serco Inc.’s Defiant testbed has been designed from the ground up with the knowledge that there will never be a human onboard while it’s at sea. Conceived as being capable of operating autonomously for months to years with minimal maintenance, the vessel is already being eyed by the Navy as a path to fielding a fleet of missile-laden drone boats in the future.

Defiant is being procured under the Defense Advanced Research Projects Agency’s (DARPA) No Manning Required Ship (NOMARS) program, which aims to field a new medium uncrewed surface vessel (MUSV) prototype. The NOMARS program was launched in 2020, and Serco’s involvement in it stretches back to that time.

In 2022, the company was awarded a $68.5 million total-value contract to build, test, and demonstrate its solution as the prime contractor. This is all prior to the start of more rigorous at-sea testing, which a representative for Serco confirmed to The War Zone on the floor of the Navy League’s Sea Air Space symposium this week is scheduled to start in January 2025.

Military chiefs scramble to rush UK’s new laser ‘death ray’ into service amid fears over Russian missiles and drones – with hi-tech DragonFire system to be fitted to Royal Navy warships

Military chiefs are to rush devastating laser guns into service to meet the threat posed by Russian drones and missiles.

Royal Artillery troops will test the revolutionary ‘DragonFire’ weaponry, which burns holes through incoming enemy ordnance, during the summer.

The sudden urgency to roll out a suite of ‘directed energy weapons’ follows the Kremlin’s alarming effective use of Unmanned Aerial Vehicles (UAVs) in Ukraine.

British soldiers will also experiment with radio frequency weapons capable of firing magnetic pulses at enemy targets thereby cutting off their power supplies.

Last night, UK Defence Secretary Grant Shapps boasted that Britain is leading the world in the development of these breakthrough technologies.

Mind Reading Technology May be Used For ‘National Security’

An ever-growing list of brain activity monitoring technologies, agencies and programs have given rise to the notion of using what comes out of such ventures – mind reading abilities – for national security threat prevention via pre-crime surveillance.

SFGate reported Tuesday that ‘we may need to rethink freedom of thought’ due to mind reading nanotech, while The Information reported Monday that AI is now being used to read the mind, leading to ‘consequences from the data gold rush’.

During a 2006 congressional discussion regarding the Electronic Surveillance Modernization Act which was aimed at greatly expanding U.S. government surveillance powers, congressman Pete Hoekstra, Republican member of the House Intelligence Committee spoke to the concept of using emerging technologies in the realm of ‘intention understanding’ to scan the public for potential terroristic thoughts.

“Our country needs to rapidly and effectively bring every intelligence tool to bear to find our enemies, detect and understand their intentions, and thwart their hostile and terrorist acts against our country and our people,” Hoekstra said.

The Congressman’s goal of utilizing ‘every’ intelligence tool to ‘detect and understand’ target’s intentions implies knowing what is being thought within the brains of whomever the government deems ‘interesting‘.

GROUNDBREAKING NON-INVASIVE UNIVERSAL BRAIN-COMPUTER INTERFACE LETS PEOPLE PLAY VIDEO GAMES USING ONLY THEIR MIND

In a groundbreaking development, engineers at the University of Texas at Austin recently unveiled a universal brain-computer interface (BCI) technology that allows individuals to control video games solely with their minds. 

This innovative advancement could represent a leap forward in the scientific quest to harness the brain’s potential, possibly revolutionizing how we interact with digital devices and offering new horizons for individuals with motor disabilities.

The core of this new brain-computer interface breakthrough lies in its unique ability to bypass extensive calibration, which has long hampered the mainstream adoption of BCI technologies. Traditional interfaces must consider individuals’ unique neural patterns, thereby demanding that the devices be custom-tuned for each user. 

However, researchers say they’ve developed a “one-size-fits-all” system that uses machine learning to dynamically adapt to users’ needs. The result is a seamless experience and a universal brain-computer interface that can shift from one person to another without the cumbersome need for recalibration. 

“When we think about this in a clinical setting, this technology will make it so we won’t need a specialized team to do this calibration process, which is long and tedious,” Satyam Kumar, a UT graduate student and study co-author, said in a press release. “It will be much faster to move from patient to patient.”

The device uses a cap filled with electrodes to measure electrical signals in the brain. A sophisticated machine learning decoder then translates a user’s neural activity into game actions. Whether navigating the twists and turns of a racing game or balancing a digital bar, researchers say the interface learns and self-calibrates through repetition, making it a universally applicable solution.

Researchers demonstrated their novel universal brain-computer interface by having 18 test subjects play a car racing game similar to Mario Kart. Donning the cap filled with electrodes, participants successfully navigated complex courses using nothing but thought. Study findings were recently published in the journal PNAS Nexus. 

At the South by Southwest Conference in Austin, Texas, from March 8 to 16, researchers showcased the broader potential of the new universal brain-computer interface. During the conference, volunteers quickly learned to control hand and arm rehabilitation robots using only their thoughts and the interface, demonstrating its versatility and user-friendliness.

The universal BCI technology developed by the UT team represents a significant shift away from other BCI technologies, such as Neuralink. Notably, Neuralink made headlines when a 29-year-old man who is paralyzed used their implant to post a tweet on the social media platform X by just thinking about it.

Japan Warns AI Could Cause Total Collapse of the Social Order

Two top Japanese companies have warned that artificial intelligence could cause a total collapse of the social order if it is not rapidly reigned in.

Nippon Telegraph and Telephone (NTT) and Yomiuri Shimbun Group Holdings, the country’s largest telecommunications company and the country’s biggest newspaper, jointly published the AI manifesto.

It warned that if legislation is not passed quickly in major countries across the world, artificial intelligence threatens to decimate democracy and provoke widespread societal unrest.

Pointing to AI programs being developed by US tech giants, the manifesto warns, “In the worst-case scenario, democracy and social order could collapse, resulting in wars.”

The report stated that such technology is designed to seize users’ attention with little regard for morality or accuracy.

Guided by Keio University researchers, the companies called on the Japanese government to pass new laws to protect elections and national security from AI.

As we previously highlighted, programs such as Google’s Gemini AI system caused fury after they openly discriminated against white people and in some cases erased them from history altogether.

OpenAI’s ChatGPT produced equally ludicrous content, in one case saying it would refuse to quietly utter a racial slur that no human could hear in order to save 1 billion white people from a “painful death.”

Manta Ray High-Endurance Underwater Drone Unveiled

Northrop Grumman has completed the construction of its first full-scale Manta Ray uncrewed underwater vehicle, or UUV, prototype. The company is developing the drone under the Defense Advanced Research Projects Agency (DARPA) Manta Ray program, which seeks to demonstrate critical technologies for a new class of very long-endurance payload-capable UUVs. 

The news was announced by Northrop earlier today, along with the release of the first image of its full-size testbed, seen in the feature image of this article. Now that its assembly has been finalized, the next step will be to actually test it, which Northrop has previously said will take place at some stage this year.

While details on the overall dimensions of the prototype have not been made public, Northrop describes it as an “extra-large glider” that draws inspiration from the “graceful glide” of the manta ray. In mimicking the shape and movement of the fish after which it’s named, Northrop’s drone features a lifting body that has sea glider-like properties, but is not a glider in the true sense of the term (i.e., it does not strictly employ variable-buoyancy propulsion alone instead of thrusters or propellers to move it forward).

In the video below, released by Northrop in 2022, we see computer-generated footage of Manta Ray being propelled via four small propellers. Imagery of the full-size testbed released by Northrop today also shows the presence of rear propellers, of which there appear to be two, rather than four.

US company hoping to bring back the dodo and the mammoth – but here’s why it won’t be like Jurassic Park

The idea of scientists bringing pre-historic creatures back to life with some clever DNA trickery might sound familiar to fans of the 1993 Hollywood blockbuster Jurassic Park.

But for Colossal Biosciences – a company that hopes to reintroduce extinct species such as the dodo and the mammoth – it is more than just a film script.

It’s a reality – and one that could be just years away.

“We’ve got all the technology we need,” says Ben Lamm, chief executive of the firm, based in Dallas, Texas.

“It is just a focus of time and funding. But we are 100% confident [we can bring back] the Tasmanian tiger, the dodo, and the mammoth.”

The science behind the project is simple: Work out the genes that make an extinct animal what it is, and then replicate those genes using the DNA of a close existing relative.

“It’s almost reverse Jurassic Park,” says Mr Lamm, speaking to Sky News.

“In the film, they were filling in the holes in the dinosaur DNA with frog DNA.

“We are leveraging artificial intelligence and other tools to identify the core genes that make a mammoth a mammoth and then engineering them into elephant genomes.”
