    That's y so many ppl come to Perú to get their teeth fixed, it's super cheap compared to other countries. a recommendation if any one of you wants to do some tourism+ at the same time getting ur teeth fixed.although, right now my country is fuvked up and not a good moment to visit(we are in the middle of a possible Civil War going off). But after all that **** is over, 10/10 recommended
    If you feel confident to fly.

    Otherwise, it could be quite a long drive for some!

    Garret Model a scientist at the University of Colorado has developing a functioning "free energy"/ zero point energy technology that uses nanotechnology.

    I was told personally by another scientist that this technology will be released to the GENERAL PUBLIC in 2023. While it is exciting, it is only currently useful for small scale energy generation. Imagine a coin cell battery that you never need to change or charge.

    The future is going to be bright

    Reminds of a long dormant wish. “Attention passengers, is there a pilot on board?” ~8D

    Four decades since I piloted, and then only a 2-seater, but am pretty sure I could navigate and land an airliner — with help via radio, of course, for all the systems and gizmos.

    Now I’m thinking about destinations. Hey nzn, how’s the food in Peru? 😎✈️👻

    A genius new use for a common item: chainsaw chain used as a hand saw.

    Compact storage for car carry, can cut fairly large logs compared to bulkier normal handsaws. Think of tree-fall/log-fall across roads.

    Seems to use standard chain (except for one specialized variant), so a DIY one should be cheaper and readily customized for length (their longer model, 93 cm (36,6 in), costs more).

    Base version: Weight: 132 g (4.7 oz)
    Chain length: 65 cm (25.6 in)
    Number of links with cutter teeth: 33
    Cost: $49. (I assume US$, tho not sure because OP is Canadian)

    I am somewhat amazed that this story is not getting more press, afterall all this is about an infinite supply of fresh water.

    Seawater split to produce green hydrogen



    Researchers have successfully split seawater without pre-treatment to produce green hydrogen.

    The international team was led by the University of Adelaide’s Professor Shizhang Qiao and Associate Professor Yao Zheng from the School of Chemical Engineering.

    “We have split natural seawater into oxygen and hydrogen with nearly 100 per cent efficiency, to produce green hydrogen by electrolysis, using a non-precious and cheap catalyst in a commercial electrolyser,” said Professor Qiao.

    A typical non-precious catalyst is cobalt oxide with chromium oxide on its surface.

    “We used seawater as a feedstock without the need for any pre-treatment processes like reverse osmosis desolation, purification, or alkalisation,” said Associate Professor Zheng.

    “The performance of a commercial electrolyser with our catalysts running in seawater is close to the performance of platinum/iridium catalysts running in a feedstock of highly purified deionised water.

    Quote Our work provides a solution to directly utilise seawater without pre-treatment systems and alkali addition, which shows similar performance as that of existing metal-based mature pure water electrolyser.
    The team published their research in the journal Nature Energy.

    “Current electrolysers are operated with highly purified water electrolyte. Increased demand for hydrogen to partially or totally replace energy generated by fossil fuels will significantly increase scarcity of increasingly limited freshwater resources,” said Associate Professor Zheng.

    Seawater is an almost infinite resource and is considered a natural feedstock electrolyte. This is more practical for regions with long coastlines and abundant sunlight. However, it isn’t practical for regions where seawater is scarce.

    Seawater electrolysis is still in early development compared with pure water electrolysis because of electrode side reactions, and corrosion arising from the complexities of using seawater.

    “It is always necessary to treat impure water to a level of water purity for conventional electrolysers including desalination and deionisation, which increases the operation and maintenance cost of the processes,” said Associate Professor Zheng.

    “Our work provides a solution to directly utilise seawater without pre-treatment systems and alkali addition, which shows similar performance as that of existing metal-based mature pure water electrolyser.”

    The team will work on scaling up the system by using a larger electrolyser so that it can be used in commercial processes such as hydrogen generation for fuel cells and ammonia synthesis.

    I'm currently in the final stages of developing a analog synthesizer sequencer and while it isn't anything groundbreaking technology wise, I think explaining the cost and capabilities of the chips I use is relevant here.

    One type of "computer" that doesn't get talked about much is the microcontroller. Almost every electronic device that a person interacts with contains one or more microcontrollers meaning your cell phone, car, microwave, "smart" lights etc...

    The company ARM used to have a marketing slogan of "You have 8 microcontrollers within ARMS reach right now" this is likely true for half the people reading this, I've got like 20 [mostly in synthesizers] and at least 2 in my phone.

    A microcontroller is basically a miniature computer that can send and recieve both analog and digital information.

    I'm using a microcontroller in order to read digital data ( 1's and 0's) from a LIDAR (laser distance sensor) that represents the distance from my hand to the device.

    The microcontroller then saves these distance readings and plays them back as a sequence by outputting analog voltages.

    The microcontroller makes sure these voltages cause analog synthesizer to play in tune notes from a variety of music scales (major, minor, mixolydian etc)

    What really blew me away was the fact that the microcontroller I'm using only cost $2.00?!?!

    I bought 100 of them for $2.00

    It's clock runs at 64 megahertz meaning information [1 and 0's] move through the microcontroller at 64 million times per SECOND?!?!

    I sure don't need to do anything that fast, it is kinda hard to wrap your head around writing code that actually runs that fast. I often have a feeling that I need to slow the thing down (so it won't get hurt) This is unnecessary of course. I'm self taught with electronics stuff and for a year or 3 I used to intentionally slow down microcontrollers in code (so it would not get hurt...) wouldn't you have done the same ??!?!!

    The LIDAR can only send reading 20,000 times a second, but considering I only need readings at most 960 times a minute[16ths notes at 240bpm] this thing is way more powerful than I need.
    Right now I pay $10 for a LIDAR breakout but I might start making my own which would save a few bucks.

    There are lot more nerdy stats about this thing, but I want bore you.

    The future is now more or less.

    Anyone else here involved in hardware development?

    Hypersonic plane to travel from New York to London in one hour

    The UK Space Agency announced its plan for a "space plane" that will travel between New York and London in one hour, and it's expected to hit the sky by the 2030s. In that case, insanely fast passenger aircraft will fly at Mach 5.4, which means really fast.

    On Tuesday, at the UK space conference in Wales, the UK Space Agency CEO revealed that this high tech plane or rocket shuttle would be powered by a hypersonic engine. These speed capabilities will change air travel, capable of traveling five minutes at the speed of sound.

    And shockingly enough, the Sabre (Synergetic Air-Breathing Rocket Engine) engine is fitted with a complex cooling system, far beyond what any typical aircraft would carry. The engine isn't terrible for the environment, will reportedly make a hypersonic travel option for commercial passengers. The main thing is to start the engine is like a hybrid of a rocket and an aero-engine fuelled by the combination of Oxygen, hydrogen, so it allows a rocket to breathe air. SABRE is supposedly greener and cheaper than current air travel.



    Sabre Advances in Technology and New Trends
    According to the Program Director Shaun Driscoll of Reaction Engines at the conference, heat has been the limiting factor. The pre-coolers are critical in the plane development because it contains liquid helium that can cool engine from more than 10, 000 degree Celsius to room temperature in one-twentieth of a second.

    Sabre is intended to provide a lightweight, efficient propulsion system to create a space plane that draws Oxygen into the engine to use for combustion from take off until it reaches just over 4000 mph. Sabre is intended to carry a much lighter and convenient rocket engine because it would carry less fuel oxidant and a 50% faster engine than the supersonic turbojet Concorde.



    Design of Supersonic Planes Skies Faster Than Sound
    The Government had already invested 74 million dollars into SABRE. In contrast, the Reaction engine continues to use the space plane's experimental engine until it reaches 25 times the sound's speed to enter space.

    However, the company aims to create a reusable vehicle that uses fuel efficiently, like a jet engine with a rocket's power. The hypersonic plane strives to match Rolls-Royce, BAR Systems, and Boeing superfast model to take people or cargo into space and back for just a fraction of the current cost.

    China comes up with the world’s first EV that runs on SODIUM-ion battery!

    China now holds all the top patents & the city of Changsha has become the epicentre of research in this field.

    Sodium is 1/100th as cheap as Lithium. Plus, this battery doesn’t require Cobalt or Nickel.

    Chinese EV giant BYD already has a model (Seagull) that comes with sodium-ion batteries as an option.

    CATL will start mass production of these batteries; and China is expected to have 95% of the market share.

    It’s the next big thing in EV.

This all-electric vehicle is capable of reaching mind-boggling speeds of up to 1000 km/ph (621 mph), surpassing the velocity of numerous private jets and effortlessly outpacing high-speed trains by a factor of three.

    Transpod envisions FluxJet as the centerpiece of its exclusive transport network, aptly named the Transpod line, which will span major cities worldwide. The ultimate objective is to offer frequent departures that facilitate swift, affordable, and secure travel—an experience that remains impervious to the constraints of traffic congestion.

    FluxJet, the epitome of emission-free transportation, boasts a remarkable capacity of accommodating 54 passengers and two wheelchairs. Additionally, it features ample luggage racks to stow passenger bags, with the ability to transport up to ten tonnes of cargo per journey.

    As part of its progressive expansion, Transpod embarks on the next phase of development—the construction of the Transpod Line, which will connect the Canadian cities of Calgary and Edmonton at a staggering cost of US$18 billion. The preliminary assessments for this ambitious project have already commenced, and once construction is underway, it is projected to generate 140,000 jobs while contributing a substantial US$19.2 billion to the region's GDP.



    When the Transpod Line becomes fully operational, it promises to reduce travel costs by an astounding 44 percent in comparison to commercial air travel along the same route. Furthermore, it will spearhead an impressive reduction in carbon emissions, amounting to a remarkable 636,000 tonnes per year. This revolutionary transportation solution offers both sustainability and economic viability as a compelling alternative to short-haul air travel.

    Sebastien Gendron, the visionary co-founder and CEO of Transpod, expresses his enthusiasm, stating, "Years of relentless effort have led us to this momentous milestone where dreams become tangible realities. The technology is tested and proven, and with the unwavering support of investors, governments, and partners, we are poised to redefine transportation in an unprecedented manner."

    Scheduled for launch in 2035, FluxJet's remarkable speed eclipses that of other high-speed ground transport concepts on the horizon. Notably, it surpasses the recently announced world's fastest bullet train in China, set to connect Shanghai and Beijing in a mere four hours, as well as the highly anticipated Virgin Hyperloop, slated to achieve speeds of 600 miles per hour by 2030.

    Prepare to embark on a new era of transportation—a realm where FluxJet seamlessly blends perplexity and burstiness, revolutionizing the way we traverse the globe with unparalleled speed, affordability, and sustainability.

    This isn't an 'invention' (yet), but if this breakthrough if for real it could change everything.
    First Room-Temperature Ambient-Pressure Superconductor Achieved, Claim Scientists

    Someone with a lab please try to reproduce these results so we know if we should pop the champagne.


    Levitation is only one of the properties of superconducting materials.

    South Korean scientists have announced the development of a room-temperature ambient-pressure superconductor. If the claim is verified, this will change the world. Superconductors transmit electricity without resistance and have a series of magnetic properties that make them invaluable in technological applications. Usually, superconductors need to be cooled down to very low temperatures. A superconductor capable of working outside the lab in regular conditions would be revolutionary.

    However, the conditional clauses in the first paragraph are necessary. There have been previous claims of room-temperature superconductivity that have not panned out. The researchers uploaded a paper to arXiv, and it is unclear if it was submitted for peer review to a journal. IFLScience has emailed them to learn more about the research and the new material, which is called modified lead-apatite or LK-99.

    One crucial aspect of superconductivity is critical temperature, the temperature below which the material becomes superconductive. The value stated for LK-99 is 127°C ( 261°F), meaning it could easily be employed in all environments on Earth. If this is confirmed, it would not be the only room-temperature superconductor. But it would be the first to not require enormous pressures to work.

    The team also recorded the critical current in the material, the lack of electrical resistance, the critical magnetic field, as well as the Meissner effect. This is the ability of a superconductor to expel the magnetic field during its transition leading to the capacity to repel nearby magnets, allowing the material to levitate. These properties led the team to claim that LK-99 is indeed a superconductor.

    “All evidence and explanation lead that LK-99 is the first room-temperature and ambient-pressure superconductor. The LK-99 has many possibilities for various applications such as magnet, motor, cable, levitation train, power cable, qubit for a quantum computer, THz Antennas, etc. We believe that our new development will be a brand-new historical event that opens a new era for humankind,” the researchers wrote in the paper.

    The reason for superconductors' lack of electrical resistance is to be found in the electron’s behavior. When the material achieves superconductivity, its electrons overcome their repulsion and pair up, flowing freely without loss of energy. The team argues that this is happening in LK-99 because of the stress caused by copper atoms on the lead, which is not relieved by the structural uniqueness of the material.

    The paper is available at arXiv.

    Comeback for Cold Fusion

    "Major Funding Provided by a US Government Agency

    By Rahul Rao, Popular Science
    https://www.popsci.com/science/cold-...lear-reaction/

    Earlier this year, ARPA-E, a US government agency dedicated to funding advanced energy research, announced a handful of grants for a field it calls “low-energy nuclear reactions,” or LENR. Most scientists likely didn’t take notice of the news. But, for a small group of them, the announcement marked vindication for their specialty: cold fusion.

    Cold fusion, better known by its practitioners as LENR, is the science—or, perhaps, the art—of making atomic nuclei merge and, ideally, harnessing the resultant energy. All of this happens without the incredible temperatures, on the scale of millions of degrees, that you need for “traditional” fusion. In a dream world, successful cold fusion could provide us with a boundless supply of clean, easily attainable energy.

    Tantalizing as it sounds, for the past 30 years, cold fusion has largely been a forgotten specter of one of science’s most notorious controversies, when a pair of chemists in 1989 claimed to achieve the feat—which no one else could replicate. There is still no generally accepted theory that supports cold fusion; many still doubt that it’s possible at all. But those physicists and engineers who work on LENR believe the new grants are a sign that their field is being taken seriously after decades in the wilderness.

    “It got a bad start and a bad reputation,” believes David Nagel, an engineer at George Washington University, “and then, over the intervening years, the evidence has piled up.”

    Igniting fusion involves pressing the hearts of atoms together, creating larger nuclei and a fountain of energy. This isn’t easy. The protons inside a nucleus give it a positive charge, and like-charged nuclei electrically repel each other. Physicists must force the atoms to crash together anyway.

    Normally, breaking this limit needs an immense amount of energy, which is why stars, where fusion happens naturally, and Earthbound experiments reach extreme heat. But what if there were another, lower-temperature way?

    Scientists had been theorizing such methods since the early 20th century, and they’d found a few tedious, extremely inefficient ways. But in the 1980s, two chemists thought they’d made one method work to great success.

    The duo, Martin Fleischmann and Stanley Pons, had placed the precious metal palladium in a bath of heavy water: a form of H2O whose hydrogen atoms have an extra neutron, a form known as deuterium, commonly used in nuclear science. When Fleischmann and Pons switched on an electrical current through their apparatus and left it running, they began to see abrupt heat spikes, or so they claimed, and particles like neutrons.

    Those heat spikes and particles, according to them, could not be explained by any chemical process. What could explain them were the heavy water’s deuterium nuclei fusing, just as they would in a star.
    If Fleischmann and Pons were right, fusion could be achievable at room temperature in a relatively basic chemistry lab. If you think that sounds too good to be true, you’re far from alone. When the pair announced their results in 1989, what followed was one of the most spectacular firestorms in the history of modern science. Scientist after scientist tried to recreate their experiment, and no one could reliably replicate their results.

    Pons and Fleischmann are remembered as fraudsters. It likely didn’t help that they were chemists trying to make a mark on a field dominated by physicists. Whatever they had seen, “cold fusion” found itself at respectable science’s margins.

    Still, in the shadows, LENR experiments continued. (Some researchers tried variations on Fleischmann and Pons’ themes. Others, especially in Japan, sought LENR as a means of cleaning up nuclear waste by transforming radioactive isotopes into less dangerous ones.) A few experiments showed oddities such as excess heat or alpha particles—anomalies that might best be explained if atomic nuclei were reacting behind the scenes.

    “The LENR field has somehow, miraculously, due to the convictions of all these people involved, has stayed alive and has been chugging along for 30 years,” says Jonah Messinger, an analyst at the Breakthrough Institute think tank and a graduate student at MIT.

    Fleischmann and Pons’ fatal flaw—that their results could not be replicated—continues to cast a pall over the field. Even some later experiments that seemed to show success could not be replicated. But this does not deter LENR’s current proponents. “Science has a reproducibility problem all the time,” says Florian Metzler, a nuclear scientist at MIT.

    In the absence of a large official push, the private sector had provided much of LENR’s backing. In the late 2010s, for instance, Google poured several million dollars into cold fusion research to limited success. But government funding agencies are now starting to pay attention. The ARPA-E program joins European Union projects, HERMES and CleanHME, which both kicked off in 2020. (Messinger and Metzler are members of an MIT team that will receive ARPA-E grant funds.)

    By the standards of other energy research funding, none of the grants are particularly eye-watering. The European Union programs and ARPA-E total up to around $10 million each: a pittance compared to the more than $1 billion the US government plans to spend in 2023 on mainstream fusion.
    But that money will be used in important ways, its proponents say. The field has two pressing priorities. One is to attract attention with a high-quality research paper that clearly demonstrates an anomaly, ideally published in a reputable journal like Nature or Science. “Then, I think, there will be a big influx of resources and people,” says Metzler.

    A second, longer-term goal is to explain how cold fusion might work. The laws of physics, as scientists understand them today, do not have a consensus answer for why cold fusion could happen at all.
    Metzler doesn’t see that open question as a problem. “Sometimes people have made these arguments: ‘Oh, cold fusion contradicts established physics,’ or something like that,” he says. But he believes there are many unanswered questions in nuclear physics, especially with larger atoms. “We have an enormous amount of ignorance when it comes to nuclear systems,” he says.

    Yet answers would have major benefits, other experts argue. “As long as it’s not understood, a lot of people in the scientific community are put off,” says Nagel. “They’re not willing to pay any attention to it.”

    It is, of course, entirely possible that cold fusion is an illusion. If that’s the case, then ARPA-E’s grants may give researchers more proof that nothing is there. But it’s also possible that something is at work behind the scenes.

    And, LENR proponents say, the Fleischmann and Pons saga is now fading as younger researchers enter the field with no memory of 1989. Perhaps that will finally be what lets LENR emerge from the pair’s shadow.“If there is a nuclear anomaly that occurs,” says Messinger, 'my hope is that the wider physics community is ready to listen.'

    ... Superconductor breakthrough replicated, twice, in preliminary testing

    Humanity may be in the throes of another breakthrough that's every bit as impactful as the invention of the transistor and the advent (and eventual vindication) of quantum computing. LK-99, as it's been named, is a new compound that researchers believe will enable the fabrication of room-temperature, ambient-pressure superconductors. Initially published by a Korean team last Friday, frantic work is underway throughout the research world to validate the paper's claims. For now, two separate sources have already provided preliminary confirmations that this might actually be the real thing — Chinese researchers have even posted video proof. Strap in; this is a maglev-powered, superconducting ride.

    Superconductors, a wild category of compounds that can conduct electricity without any losses, have been a metaphorical goose chase for years now, with multiple research teams claiming (and then retracting) papers and announcements of its achievement. The reason is simple: Few things come close to the potential of an actual superconductor discovery in terms of what it can do for humanity's current and future technology. Imagine if your 16-core mainstream CPU (which likely requires a competent watercooling solution to avoid incinerating itself) operated without power losses — no current leakage, no electricity waste in the form of heat. Superconductors mean almost perfectly efficient computing.

    Scale that to the world's supercomputers, and you begin to get an idea of the performance impact when trillions of transistors based on superconducting materials work in tandem across GPU and CPU tiles to accelerate things like Artificial Intelligence (AI) workloads. Or scale it in the realm of consumer electronics, quantum computing (where superconductors are important for Josephson junctions), and magnets in general (maglev trains, tokamak fusion reactors, Magnetic Resonance Imaging (MRI), electric motors and generators...)

    If you can dream it and it features an electrical current or magnetism, it's likely a superconducting material would improve most aspects of it while leaving a surplus of previously-wasted energy within humanity's batteries. Environmental sustainability, then, is also a factor.

    There might be more to LK-99 than skeptics expected, as two research teams have already confirmed the superconductivity claims — albeit in preliminary testing. Researcher Sinéad Griffin from the U.S.'s Lawrence Berkeley National Lab pored over the original paper, taking advantage of the supercomputing capabilities within the Department of Energy to simulate the LK-99 material. This complex-yet-simple concoction results from combining the minerals lanarkite (Pb₂SO₅) and copper phosphide (Cu₃P), which are then baked within a 4-day, multi-step, small batch, solid-state synthesis process.

    As a result of the simulations, the researcher published an analysis letter in pre-print form to Arxiv, where she confirmed that the resulting material should manifest the superconduction pathways for electrons to travel through unimpeded and without any resistance. Interestingly, she noticed that these superconducting pathways only form in very specific areas of the compound, namely the highest-energy areas of the resulting crystal lattice.

    Because physics dictates that systems tend to remain stable at their lowest-possible energy states, this means that the amount of superconducting material produced with each "shake-and-bake" manufacturing attempt will result in relatively low quantities of the material. The hope, then, is that further refinements to the fabrication process will yield higher quantities of the material that can then be harvested and put toward building the superconductors themselves.

    But in what's perhaps the most definite sign of a verification, Chinese researchers with the Huazhong University of Science and Technology have claimed to have successfully replicated the superconductor's manufacturing process, posting a video on Twitter as proof (expand the tweet above to see the video).

    The above video showcases the Meissner effect as being definite proof of the material's superconducting capabilities. The Meissner effect refers to the expulsion of a magnetic field due to the superconducting process. It is the reason why the video showcases levitating materials — they are interacting with LK-99's Meissner-induced magnetic field.

    The entire story surrounding this discovery is a scientific rollercoaster ride, with rogue scientists, updated papers, plus cloudy definitions and process descriptions within the paper that make replication efforts more difficult, and even a Russian soil scientist (and anime catgirl) deconstructing the original Korean paper to unveil the trademark levitation of the Meissner effect over her own kitchen counter.

    We've seen movies with much less complex plots than this already. It's eerily appropriate that such a monumental discovery would be rife with drama. And we're still waiting for a definite announcement that yes, humanity has finally produced room-temperature, ambient-pressure superconductors. After that, there are plenty more physics barriers to crash through, as always.
