@Tiger-1 Here is an article which will help you out: https://cleantechnica.com/2016/05/3...motor-ideal-choice-21st-century-electric-car/ Nikola Tesla, the inventor from former Yugoslavia, indebted us all in more ways than we can imagine... Here is another one... A 100 year old Tesla's invention suddenly gets a proper review and new applications, as our scientists are still trying to fully understand it.... https://www.independent.co.uk/life-...ZU4IuLubNzpyJV89hUOp2iwAlUCvXCQb2OYXgHNxw1XRc 100-year-old Tesla invention is ‘useful in ways we hadn’t realised’ 100-YEAR-OLD TESLA INVENTION ‘STILL NOT COMPLETELY UNDERSTOOD’ IS USEFUL IN WAYS WE HAD NOT REALISED, SCIENTISTS SAY A 100-year-old Tesla invention is actually useful in ways scientists had not realised, according to new research. Nikola Tesla won a patent for the device he created in 1920, one of many breakthrough inventions created by the engineer and futurist. But more than a century on, scientists have found that the “Tesla Valve” is not only more useful than previously realised, but that it could have other entirely new applications. “It’s remarkable that this 100-year-old invention is still not completely understood and may be useful in modern technologies in ways not yet considered,” said Leif Ristroph, an associate professor in New York University’s Courant Institute of Mathematical Sciences and the paper’s senior author, in a statement. “While Tesla is known as a wizard of electric currents and electrical circuits, his lesser-known work to control flows or fluid currents was truly ahead of its time.” Tesla referred to the device as a “valvular conduit”, though it has since been named after him, and is made up of a series of teardrop-shaped loops attached in a row. He created it as a way of allowing fluids to pass through in only one direction, without requiring any moving parts. Comparison of flows in the reverse direction (right to left) at three different speeds. The water current is visualized with green and blue dyes, showing that the flows are increasingly disrupted at higher speeds (NYU's Applied Mathematics Laboratory) But it could also be used for other functions, researchers say. They found that the device works something like a “switch”: it is only when there is enough liquid coming through that it works to resist flows coming in the wrong direction. Scientists suggest that behaviour could be harnessed in a vareity of new ways, including being used to pump fuel or other liquids inside engines and machinery. They also believe that it could indicate something of what Tesla was looking to achieve when he was working on the invention. “Crucially, this turn-on comes with the generation of turbulent flows in the reverse direction, which ‘plug’ the pipe with vortices and disrupting currents,” said Professor Ristroph.

https://bigthink.com/technology-innovation/flash-graphene?rebelltitem=2#rebelltitem2 Graphene typically costs $200,000 per ton. Now, scientists can make it from trash. Graphene is insanely useful, but very difficult to produce — until now. MATT DAVIS 31 January, 2020 The new technique, developed at Rice University, turns any carbon source into the valuable 2D material in just 10 milliseconds. Jeff Fitlow Graphene is a lattice of carbon atoms arranged in a chicken-wire formation, a structure that makes it very useful for a wide range of applications. However, it's been very difficult and expensive to make. This new technique cuts down on the cost and difficulty by flash heating any carbon-based material, such as used coffee grounds or plastic waste. Recent technology developed at Rice University is taking the idea that one man's trash is another man's treasure to its extreme. Banana peels, coffee grounds, single-use plastic containers, coal — all of these and more are being turned into one of the most valuable materials around: graphene. Chemist James Tour and his team have developed a rapid process that can transform bulk-quantities of junk into flakes of graphene. "This is a big deal," said Tour in a Rice University press release. "The world throws out 30 percent to 40 percent of all food, because it goes bad, and plastic waste is of worldwide concern. We've already proven that any solid carbon-based matter, including mixed plastic waste and rubber tires, can be turned into graphene."
Combine with: https://www.offgridenergyindependen...ally-help-in-the-fight-against-climate-change Can Direct Air Capture Really Help in the Fight Against Climate Change Carbon capture technology may be essential in helping the world in the fight against climate change. By fitting fossil fuel power stations and industrial emitters with carbon capture technology, it is possible to reduce their carbon dioxide emissions by over 90%. Until renewable energy is capable of providing the bulk of the world's power needs, carbon capture may have to play a major role if the world is to meet the 2°C warming target outlined by the Paris Agreement. "Carbon Capture, Utilization, and Storage 2021-2040", a new report by IDTechEx, explores the technical and industrial factors that will play a role in deciding whether carbon capture technology can live up to its potential as a key technology in the fight against climate change. However, capturing CO2 from point sources such as power stations and steel manufacturing plants may not be enough to avoid the worst impacts of climate change. Most scenarios outlined by the Intergovernmental Panel on Climate Change (IPCC) for keeping the world below 2°C of warming require the active removal of CO2 from the atmosphere. Outside of bioenergy with carbon capture and storage (BECCS), which remains highly unproven, this is not possible with point source carbon capture. A potential solution is direct air capture (DAC) technology, which uses carbon capture techniques to strip CO2 from atmospheric air. The technology has generated much excitement around the world, with many hoping it could help to directly reverse the impacts of climate change. However, despite the enthusiasm, the technology is still at a very early stage, is unproven at scale, and is currently far more expensive than point-source carbon capture. So, does DAC justify the excitement or is it doomed to fail? And why not just plant trees instead? electrochemical method for converting atmospheric CO2 into fuels using water, electricity, and carbon nanotube membranes. Other companies such as Infinitree and Skytree are developing innovative solutions for removing CO2 from the local atmosphere. Despite the optimism around DAC, the technology still faces some serious hurdles before it can reach the scale where it has a meaningful impact on climate change. The main issue at the moment is the cost of the technology. Although DAC companies have remained fairly tight-lipped around their current process costs, capturing one tonne of CO2 directly from the atmosphere is believed to cost $600-$1,300 using current technology, compared with $40-$80 for capturing one tonne of CO2 from the flue gas stream of a coal-fired power plant. IDTechEx forecasts that DAC capacity will reach 265 million tonnes of CO2 captured by 2030 and could reach 8% of global carbon capture capacity by 2040, but this will require major levels of investment and technology development. Carbon Capture, Utilization, and Storage 2021-2040" Direct air capture is an exciting technology that has the potential to actively reverse decades of damage to the atmosphere from anthropogenic emissions. However, it is not a silver bullet and DAC alone will not be enough to avoid the worst impacts of climate change. Nor is the future potential of DAC enough to justify inaction over emissions now, in the hope that future technology will solve the problem. Nevertheless, as part of a coordinated system of carbon capture technology, negative emissions technologies, and emissions reduction strategies, DAC could play an important role in creating a sustainable future. For a detailed technical and economic analysis of DAC technology, alongside point source carbon capture, carbon utilization and carbon storage methods, see the recent IDTechEx report, "Carbon Capture, Utilization, and Storage 2021-2040".
https://www.electricvehiclesresearc...istributed-propulsion-aircraft-come-to-market Distributed Propulsion Aircraft Come to Market Multiple thrusters are one thing. In vertical takeoff and landing (VTOL) they reduce the efficiency deficit with helicopters, providing unmatched redundancy and stability in wind. However, the term distributed propulsion (DP) primarily refers to a fundamentally new form of wing that intimately blends aerodynamics with thrust and zero emissions. The many benefits multiply on each other. Consider more than four propellers with their own motors along the wings and sometimes even along the tailplane. That is now affordable, reliable, and practicable. Not so with jet turbines or piston engines. Each propeller leaves a wake behind it. Air is accelerated generating thrust and, over the wing, lift. Newly possible propulsion units along the wing enable a 10% reduction in wing size - a narrower, lower-cost, lighter wing. 10% less friction drag and better control can be taken in short takeoff and landing, longer range, and/or lower aircraft cost. Enjoy enhanced safety from multiple thrust-redundancy. Watch this: https://lilium.com https://lilium.com/jet

In order to deliver this ground-breaking technology, Rolls Royce is planning an £80m investment in ESS over the next decade, that will create around 300 jobs by 2030 and strengthen its position as the leading supplier of all-electric and hybrid-electric power and propulsion systems for aviation. Aerospace-certified ESS solutions from Rolls-Royce will power electric and hybrid-electric propulsion systems for eVTOLs (electric vertical takeoff and landing) in the Urban Air Mobility market and fixed-wing aircraft, with up to 19 seats, in the commuter market. By 2035, Rolls-Royce is planning to integrate more than 5 million battery cells per annum into modular systems. Rolls-Royce says these modules will deliver market-leading energy density levels. (...) Battery pack design is a mechanical, thermal and containment design challenge and there has to be a strong focus on safety and low weight. These aspects are core to all the products that Rolls-Royce has a long history of producing in aerospace. Rolls-Royce and airframer Tecnam are currently working with Widerøe - the largest regional airline in Scandinavia - to deliver an all-electric passenger aircraft for the commuter market, which is planned to be ready for revenue service in 2026. Rolls-Royce will deliver the entire electrical propulsion system including an energy storage system for the new P-VOLT aircraft."
https://www.printedelectronicsworld...ft-electronics-dont-break-even-when-punctured Posted on June 28, 2021 New Soft Electronics Don't Break Even When Punctured Want a smartphone that stretches, takes damage, and still doesn't miss a call? A team of Virginia Tech researchers from the Department of Mechanical Engineering and the Macromolecules Innovation Institute has created a new type of soft electronics, paving the way for devices that are self-healing, reconfigurable, and recyclable. These skin-like circuits are soft and stretchy, sustain numerous damage events under load without losing electrical conductivity, and can be recycled to generate new circuits at the end of a product's life. Led by Assistant Professor Michael Bartlett, the team recently published its findings in Communications Materials, an open access journal from Nature Research. Current consumer devices, such as phones and laptops, contain rigid materials that use soldered wires running throughout. The soft circuit developed by Bartlett's team replaces these inflexible materials with soft electronic composites and tiny, electricity-conducting liquid metal droplets. These soft electronics are part of a rapidly emerging field of technology that gives gadgets a level of durability that would have been impossible just a few years ago. The liquid metal droplets are initially dispersed in an elastomer, a type of rubbery polymer, as electrically insulated, discrete drops. "To make circuits, we introduced a scalable approach through embossing, which allows us to rapidly create tunable circuits by selectively connecting droplets," postdoctoral researcher and first author Ravi Tutika said. "We can then locally break the droplets apart to remake circuits and can even completely dissolve the circuits to break all the connections to recycle the materials, and then start back at the beginning." The circuits are soft and flexible, like skin, continuing to work even under extreme damage. If a hole is punched in these circuits, the metal droplets can still transfer power. Instead of cutting the connection completely as in the case of a traditional wire, the droplets make new connections around the hole to continue passing electricity. The circuits will also stretch without losing their electrical connection, as the team pulled the device to over 10 times its original length without failure during the research. At the end of a product's life, the metal droplets and the rubbery materials can be reprocessed and returned to a liquid solution, effectively making them recyclable. From that point, they can be remade to start a new life, an approach that offers a pathway to sustainable electronics. While a stretchy smartphone has not yet been made, rapid development in the field also holds promise for wearable electronics and soft robotics. These emerging technologies require soft, robust circuitry to make the leap into consumer applications. "We're excited about our progress and envision these materials as key components for emerging soft technologies," Bartlett said. This work gets closer to creating soft circuitry that could survive in a variety of real-world applications."
https://bigthink.com/surprising-science/oxygen-animal?rebelltitem=1#rebelltitem1 Scientists discover animal that doesn't need oxygen to live It's the first time scientists have discovered an animal that doesn't perform aerobic respiration. STEPHEN JOHNSON 28 February, 2020 The animal is a tiny parasite called Henneguya salminicola. The parasite infects salmon and lives within the fish muscle, though scientists aren't quite sure how it breaks down nutrients for survival. The findings are published in the journal PNAS. In the time it takes you to read this article, you're likely to breathe a few dozen times. Some animals don't breathe as often, and they don't require nearly as much oxygen. The Loggerhead sea turtle, for example, can take one breath and stay underwater for about 10 hours. Still, it's long been thought that all animals need to breathe oxygen to stay alive. But then scientists discovered Henneguya salminicola, an 8-millimeter parasite that doesn't need oxygen to live, and cannot process it as other animals do. The findings are published in a paper in the journal PNAS. All other animals have mitochondria, which are organelles that act as the "powerhouse" of the cell by breaking down nutrients and converting them into energy. One way mitochondria do this is by converting oxygen into a fuel called adenosine triphosphate (ATP), which drives processes like muscle contraction, nerve impulse propagation, and chemical synthesis. This conversion process is called aerobic respiration. H. salminicola inside of a salmon Michal Maňas But H. salminicola — a cnidarian animal related to jellyfish and coral — don't have mitochondria, and therefore can't perform aerobic respiration. Lead study author Dorothée Huchon discovered this as she was sequencing mitochondria across Myxozoa (a class of parasites). "My goal was to assemble mitochondrial genome to study its evolution in Myxozoa and... Oops, I found one without a genome," she told Vice. "I first thought that the lack of mitochondrial genome among the DNA sequence was the result of a bug in genome analyses. But then I realized that it has lost not just the mitochondrial genome but the whole set of protein genes that interact with the mitochondrial genome and all the majority of genes involved in respiration."
And then, there's thinking... as in serious thinking... https://www.bloomberg.com/news/arti...=socialflow-twitter-climate&utm_medium=social The EU argues that the urgency of the climate crisis requires drastic action, and that residents will ultimately experience positive outcomes. “We have one decade to fundamentally change how we generate energy, move around and produce things we need,” said EU Energy Commissioner Kadri Simson. “There will be a direct impact on everybody’s life, from more electric vehicles on the roads to greener buildings, cleaner air and healthier environment.” A solar park in Laudun L’Ardoise, France. Photographer: Jeremy Suyker/Bloomberg The Fit for 55 proposal includes measures to shield the most vulnerable households from higher costs. The Climate Action Social Facility, financed with revenues from the new carbon market, will provide funding to support people who struggle to access energy or transport -- a population the EU estimates could be as large as 34 million today. Privacy Policy and Terms of Service. Strengthening the carbon market is also set to become a divisive topic for member states with varying levels of wealth that rely on different energy sources. The rapid price increases in the current ETS have already led to complaints -- mostly from eastern European countries -- that the soaring costs will undermine their ability to invest in clean technologies. One way to protect these local companies, the Commission will suggest, is to impose a carbon price on some imported goods by introducing the world’s first carbon border levy. The tool would help level the playing field for European manufacturers so their rivals from countries with looser environmental rules can’t undermine them on price. Read: The World’s First Carbon Border Tariff, Explained But companies want more help. Steel producers argue the levy should come on top of free permits to emit CO2, while the Commission says it should be one or the other. The tax, called the Carbon Border Adjustment Mechanism, is also causing diplomatic unease with countries from China to Russia, who warn that it could violate World Trade Organization rules. “The proposal today is just the first chapter of the story,” Tagliapietra said. “We will see a lot of friction and tension over the next two to three years. Europe is set to become a global laboratory for deep decarbonization and the world will have an opportunity to learn how to achieve climate targets.”
https://www.offgridenergyindependen...stal-layer-produces-thousand-times-more-power Solar Cells: Three Crystal Layer Produces Thousand Times More Power The photovoltaic effect of ferroelectric crystals can be increased by a factor of 1,000 if three different materials are arranged periodically in a lattice. This has been revealed in a study by researchers at Martin Luther University Halle-Wittenberg (MLU). They achieved this by creating crystalline layers of barium titanate, strontium titanate and calcium titanate which they alternately placed on top of one another. Their findings, which could significantly increase the efficiency of solar cells, were published in the journal Science Advances. Electric crystals do not require a so-called pn junction to create the photovoltaic effect, in other words, no positively and negatively doped layers. This makes it much easier to produce the solar panels. For further information see the IDTechEx report on Energy Harvesting Microwatt to Gigawatt: Opportunities 2020-2040. However, pure barium titanate does not absorb much sunlight and consequently generates a comparatively low photocurrent. The latest research has shown that combining extremely thin layers of different materials significantly increases the solar energy yield. "The important thing here is that a ferroelectric material is alternated with a paraelectric material. Although the latter does not have separated charges, it can become ferroelectric under certain conditions, for example at low temperatures or when its chemical structure is slightly modified," explains Bhatnagar. Bhatnagar's research group discovered that the photovoltaic effect is greatly enhanced if the ferroelectric layer alternates not only with one, but with two different paraelectric layers. Yeseul Yun, a PhD student at MLU and first author of the study, explains:// "We embedded the barium titanate between strontium titanate and calcium titanate. This was achieved by vaporising the crystals with a high-power laser and redepositing them on carrier substrates. This produced a material made of 500 layers that is about 200 nanometres thick." When conducting the photoelectric measurements, the new material was irradiated with laser light. The result surprised even the research group: compared to pure barium titanate of a similar thickness, the current flow was up to 1,000 times stronger - and this despite the fact that the proportion of barium titanate as the main photoelectric component was reduced by almost two thirds. "The interaction between the lattice layers appears to lead to a much higher permittivity - in other words, the electrons are able to flow much more easily due to the excitation by the light photons," explains Akash Bhatnagar. The measurements also showed that this effect is very robust: it remained nearly constant over a six-month period. Further research must now be done to find out exactly what causes the outstanding photoelectric effect. Bhatnagar is confident that the potential demonstrated by the new concept can be used for practical applications in solar panels. "The layer structure shows a higher yield in all temperature ranges than pure ferroelectrics. The crystals are also significantly more durable and do not require special packaging."

@ Time crystals The article states that perpetual motion is physicly impossible and then goes on to claim ' Time crystals ' do it ? Then it goes on to tell us that time crystals would / could solve ' all ' of inhumanitys problems ? and that we can use them for ' Many future technologys from teleportation to perpetual motion reactors that can power the planet without useing fuel or energy ' !!!! < ---- That sentace dissapears up its own arse . Teleportation is impossible , theres no such thing as perpetual motion and energy / power ftom a process that doesnt use , loose or create energy is impossible .
Wikipedia is a bit better Under thermodynamics Time crystals do not violate the laws of thermodynamics: energy in the overall system is conserved, such a crystal does not spontaneously convert thermal energy into mechanical work, and it cannot serve as a perpetual store of work. But it may change perpetually in a fixed pattern in time for as long as the system can be maintained. They possess "motion without energy"[34]—their apparent motion does not represent conventional kinetic energy.[35 ------- Also: In July 2021 a collaboration consisting of Google and physicists from multiple universities reported the observation of a discrete time crystal on Google's sycamore processor, a chip of 20 qubits was used to obtain a many body localization configuration of up and down spins and then stimulated with a laser to achieve a periodically driven "Floquet" system where all up spins are flipped for down and viceversa in periodic cycles which are multiples of the laser’s, no energy is absorbed from the laser so the system remains in a protected eigenstate order.[37][38]
