    Lattice Confinement Fusion NASA Detects Lattice Confinement Fusion A team of NASA researchers seeking a new energy source for deep-space exploration missions, recently revealed a method for triggering nuclear fusion in the space between the atoms of a metal solid. Their research was published in two peer-reviewed papers in the top journal in the field, Physical Review C, Volume 101 (April, 2020): “Nuclear fusion reactions in deuterated metals” and “Novel nuclear reactions observed in bremsstrahlung-irradiated deuterated metals.” Nuclear fusion is a process that produces energy when two nuclei join to form a heavier nucleus. “Scientists are interested in fusion, because...

    ORLANDO, Fla. — Temporarily blinded Saturday morning by a laser pointed at him from 1,000 feet below, a Florida Highway Patrol pilot alerted other aircraft about the flying hazard then landed his plane and began an investigation that led to the arrest of a Kissimmee man at a multi-story construction site. Guillermo Negron Roque, 47, was jailed pending a charge of pointing a laser light at a pilot, a second-degree felony. The bright flash of green light startled FHP pilot J.C. Pollock as he was flying west of Interstate 4 about 6:30 a.m. “At first I thought I was about...
  • Researchers create light waves that can penetrate even opaque materials

    Why is sugar not transparent? Because light that penetrates a piece of sugar is scattered, altered and deflected in a highly complicated way. However, as a research team from TU Wien (Vienna) and Utrecht University (Netherlands) has now been able to show, there is a class of very special light waves for which this does not apply: for any specific disordered medium—such as the sugar cube you may just have put in your coffee—tailor-made light beams can be constructed that are practically not changed by this medium, but only attenuated. The light beam penetrates the medium, and a light pattern...

    It can generate 250 terabytes of random bits per second. In fact, it was so fast that the team behind it struggled to record its output using a high-speed camera. According to the researchers, their system trumps physical random number generators both in speed and through its ability to create many bitstreams simultaneously. The results are published in the journal Science. The new invention utilizes a tiny laser, just one millimeter long, which bounces light between mirrors positioned at either end of an hourglass-shaped cavity before exiting the device, reports Science News. Unlike previous laser-based systems, the new process can...

    After decades of toiling and dead-ends, the dream of operational laser weaponry is about to become a reality. So, what changed that made what had been bulky systems go from clumsy pipe dreams to hardened, miniaturized, and reliable weapons that will be able to be deployed even in the harshest of conditions? We recently had an in-depth interview with Dr. Rob Afzal, Lockheed Martin Senior Fellow, Laser and Sensor Systems, where I pressed him on everything related to laser weaponry and the emerging military applications that go along with it. In the course of answering my maelstrom of queries, Dr....

    Image by Northrup Grumman, from, scaled and cropped by Dean Weingarten In my 30+ year career in Army Research, Development, Testing and Evaluation, (RDT&E), there was some exposure and support of laser weapons. A principle concern with lasers is how the interact with the atmosphere. That is where my old outfit came in.Lasers have been used in weapons systems since shortly after their development, for ranging and sensing, and information technology. I am writing about weapons that burn, shoot down, and blow things up.My team supported a laser weapons test about 1975 as I recall. This correspondent was not...

    The Defense Department expects to stand up its first battalion of Stryker vehicles outfitted with high-powered laser weapons by some time next year, Army officials say.“Expect to have the first battalion fielded in 2021 with four battalions by 2023,” U.S. Army Space and Missile Defense Command chief Lt. Gen. Dan Karbler told the audience at the virtual Space Missile Defense symposium on Tuesday The so-called "laser battalion," as Defense One described it, would eventually deploy the new 50 kw Directed Energy-Maneuver Short-Range Air Defense (DE-MSHORAD) Stryker that the Army is working to field by 2022, a ten-fold power increase over the 5 kw-class system...

    Once again I'm tapping the collective brain trust of Free Republic to get some answers concerning Laser Eye Protection. If you're up on current events, and if you're a Freeper, you are. You've seen antifa and blm terrorists blinding people with lasers. I just saw a video of a woman on her front porch surrounded by these terrorists and her face was green. There must have been at least 15 lasers pointed at her eyes. This does worry me and I've been researching laser protective eye protection and can't really seem to find a definitive answer as to what type...

    The U.S. Federal Protective Service is spending $125,000 on sunglasses to protect federal officers' eyes from lasers shone at them by protesters, according to a procurement request. The July 10 document cites the use of lasers by Portland protesters as a reason to buy 1,000 pairs of Stingerhawk FT-2 Laser Protective Eyewear. "Our FPS personnel saw these lasers used firsthand in Portland," the request says, "and had discussions with Seattle Police Officers who felt the effects on the first night of rioting and then utilized laser resistant safety glasses and expressed that they were very effective."

    At least three federal officers could be left permanently blind after they were attacked with lasers by protesters in Portland this week. The officers, part of the Federal Protective Service, were injured during rioting in the city on Monday night as they attempted to keep anti-government demonstrators from gaining entrance to a federal courthouse in the city's downtown area. “When officers responded to put out these fires, glass bottles were thrown and lasers – which can cause permanent blindness – were shined in their eyes,” said Deputy Director of Operations Richard Cline. “We have three officers who currently have eye...

    As astronauts explore the Moon during the Artemis program, they may need to make use of the resources that already exist on the lunar surface. Take water, for instance: Because it's a heavy and therefore expensive resource to launch from Earth, our future explorers might have to seek out ice to mine. Once excavated, it can be melted and purified for drinking and used for rocket fuel. But how much water is there on the Moon, and where might we find it? This is where NASA's Lunar Flashlight comes in. About the size of a briefcase, the small satellite —...
  • Squeezing Light Out of Silicon A hexagonal crystal could lead to lasing

    IEEE Spectrum ^ | 4/8/20 | Neil Savage
    Scientists have been chasing silicon-based lasers for years—they’d provide a faster, cheaper way to move data across or between computer chips. Now researchers say they’ve gotten efficient light emission from silicon by forcing it into a new shape. Replacing copper wires with beams of light makes it possible to send data from one transistor on a chip to another, or from one chip to another, at higher speeds and with less power, without having to worry about the excess heat generated by electrical resistance. Other types of lasers can do that, but the semiconductors they’re made of are more expensive...

    Florida man was arrested last week after he was caught on video pointing a laser — attached to an AR-15 — at a police helicopter flying overhead, the Martin County Sheriff’s Office said Friday. The sheriff’s office chopper was working with Port St Lucie Police on an unrelated burglary last Saturday when the incident took place, the sheriff’s office said. A video camera onboard the helicopter captured Norman Flaxman walking outside his home, pointing the rifle directly at the helicopter and “deploying the laser two to three times,” deputies said.
