We gaan dus vliegende auto's op de Nederlandse wegen zien rijden. Over 2 jaar.
Maar gaan we ook die auto's echt zien vliegen is ons luchtruim? Of wordt het de zoveelste vliegende auto die komende is maar waarover we later nooit meer horen?
In het filmpje zie je hem vliegen maar het is mij niet duidelijk is dit echt is of een animatie. Iemand?

Aangezien het filmpje uit 2018 is kijk ik al naarstig naar de lucht. Dan kan ik in elk geval weten of nu.nl onder dezelfde categorie als CNN.com kan worden gerangschikt.

Engineering the Scorpion: Mark Hempsell
DeltaVeeMedia - 28 apr. 2020


Scorpion is a result of a study into a large general purposed spacecraft that can deliver crew and payload to high Earth orbits, the Moon and everywhere between Venus and Mars. It has provisions for six people and has six payload attach points which enable it to carry several hundred tonnes to high Earth orbit.

The performance to achieve this comes from a nuclear engine called the Serpent. It means that the Scorpion can travel to the Moon’s surface with twenty tonnes of payload and return, while protecting the crew with full solar storm shielding and is even capable of spinning to provide the crew with artificial gravity.

Its key constraint was that the technology either currently exists or, it was in development before the 1980s but the programme was never completed. The talk will work though the key engineering decisions showing their heritage and feasibility, a showing that the Scorpion represents a system that could have been operational in the 2000- 2010 timeframe.

Researchers develop groundbreaking new rocket-propulsion system

by University of Central Florida, April 30, 2020

A University of Central Florida researcher and his team have developed an advanced new rocket-propulsion system once thought to be impossible.

The system, known as a rotating detonation rocket engine, will allow upper stage rockets for space missions to become lighter, travel farther, and burn more cleanly.

The result were published this month in the journal Combustion and Flame.

"The study presents, for the first time, experimental evidence of a safe and functioning hydrogen and oxygen propellant detonation in a rotating detonation rocket engine," said Kareem Ahmed, an assistant professor in UCF's Department of Mechanical and Aerospace Engineering who led the research.

The rotating detonations are continuous, Mach 5 explosions that rotate around the inside of a rocket engine, and the explosions are sustained by feeding hydrogen and oxygen propellant into the system at just the right amounts.

This system improves rocket-engine efficiency so that more power is generated while using less fuel than traditional rocket energies, thus lightening the rocket's load and reducing its costs and emissions.

Mach 5 explosions create bursts of energy that travel 4,500 to 5,600 miles per hour, which is more than five times the speed of sound. They are contained within a durable engine body constructed of copper and brass.

The technology has been studied since the 1960s but had not been successful due to the chemical propellants used or the ways they were mixed.

Ahmed's group made it work by carefully balancing the rate of the propellants, hydrogen and oxygen, released into the engine.

"We have to tune the sizes of the jets releasing the propellants to enhance the mixing for a local hydrogen-oxygen mixture," Ahmed said. "So, when the rotating explosion comes by for this fresh mixture, it's still sustained. Because if you have your composition mixture slightly off, it will tend to deflagrate, or burn slowly instead of detonating."

Ahmed's team also had to capture evidence of their finding. They did this by injecting a tracer in the hydrogen fuel flow and quantifying the detonation waves using a high-speed camera.

"You need the tracer to actually see that explosion that is happening inside and track its motion," he said. "Developing this method to characterize the detonation wave dynamics is another contribution of this article."

William Hargus, lead of the Air Force Research Laboratory's Rotating Detonation Rocket Engine Program, is a co-author of the study and began working with Ahmed on the project last summer.

"As an advanced propulsion spectroscopist, I recognized some of the unique challenges in the observation of hydrogen-detonation structures," Hargus said. "After consulting with Professor Ahmed, we were able to formulate a slightly modified experimental apparatus that significantly increased the relevant signal strength."

"These research results already are having repercussions across the international research community," Hargus said. "Several projects are now re-examining hydrogen detonation combustion within rotating detonation rocket engines because of these results. I am very proud to be associated with this high-quality research."

Revolutie in personenvervoer? ‘Zwevende magneet-pod is veilig en veel zuiniger dan elektrische auto’

Erik Kouwenhoven, 07-05-20, 20:00

Afbeelding

Onderzoekers aan de Radboud Universiteit werken aan een zwevende module, die aangedreven wordt door magneten in het wegdek. Ze denken dat deze vorm van 'magneto-transport’ kan zorgen voor een revolutie in het personenvervoer.

De modules of ‘pods’ worden voortgestuwd door een rij gekantelde elektromagneten net onder het oppervlak van het wegdek, die precies op het juiste moment een puls afgeven wanneer de module over ze heen zweeft. Op die manier wordt zowel het zweven als de aandrijving door één enkele bron geleverd.

Centrale computer
De module is voorzien van de nieuwste locatie-detectie hardware en communiceert volgens de universiteit voortdurend met een centrale computer. Hiermee kunnen passagiers hun bestemming kiezen en de gewenste route, om zich vervolgens vloeiend en snel naar hun eindbestemming te kunnen laten vervoeren over het wegennetwerk.

Geen remmen
Volgens hoofdonderzoeker Nigel Hussey zou het systeem niet alleen tweemaal zo energiezuinig zijn als een elektrische auto, maar ook veiliger. ,,Er is geen motor, geen wielen, geen remmen, geen ophanging, niet eens een accu. Doordat een centraal systeem de bewegingen en locaties van alle modules regelt, worden botsingen met andere modules voorkomen. Eventuele ongelukken zouden minder fataal aflopen dan wanneer je door een zware auto van zo’n anderhalve ton wordt geraakt.”

Werkend prototype
Het komende jaar zijn Hussey en zijn team bezig om te bepalen hoe kansrijk dit systeem is als een alternatief transportsysteem. Er is al een werkend schaalmodel gebouwd, maar ze willen ook een groter volledig werkend prototype bouwen, dat alle belangrijke functies incorporeert. Naast de technologie, werken de onderzoekers in Nijmegen ook aan de vele politieke, economische, maatschappelijke en milieuvraagstukken die zouden kunnen ontstaan.

By Kayla Wiles, May 13, 2020

A team of Purdue University engineers have created hardware that can learn skills using a type of AI that currently runs on software platforms. Sharing intelligence features between hardware and software would offset the energy needed for using AI in more advanced applications such as self-driving cars or discovering drugs.

"Software is taking on most of the challenges in AI. If you could incorporate intelligence into the circuit components in addition to what is happening in software, you could do things that simply cannot be done today," said Shriram Ramanathan, a professor of materials engineering at Purdue University.

AI hardware development is still in early research stages. Researchers have demonstrated AI in pieces of potential hardware, but haven't yet addressed AI's large energy demand.

As AI penetrates more of daily life, a heavy reliance on software with massive energy needs is not sustainable, Ramanathan said. If hardware and software could share intelligence features, an area of silicon might be able to achieve more with a given input of energy.

Ramanathan's team is the first to demonstrate artificial "tree-like" memory in a piece of potential hardware at room temperature. Researchers in the past have only been able to observe this kind of memory in hardware at temperatures that are too low for electronic devices.

The results of this study are published in the journal Nature Communications.

The hardware that Ramanathan's team developed is made of a so-called quantum material. These materials are known for having properties that cannot be explained by classical physics.

Ramanathan's lab has been working to better understand these materials and how they might be used to solve problems in electronics.

Software uses tree-like memory to organize information into various "branches," making that information easier to retrieve when learning new skills or tasks.

The strategy is inspired by how the human brain categorizes information and makes decisions.

"Humans memorize things in a tree structure of categories. We memorize 'apple' under the category of 'fruit' and 'elephant' under the category of 'animal,' for example," said Hai-Tian Zhang, a Lillian Gilbreth postdoctoral fellow in Purdue's College of Engineering. "Mimicking these features in hardware is potentially interesting for brain-inspired computing."

The team introduced a proton to a quantum material called neodymium nickel oxide. They discovered that applying an electric pulse to the material moves around the proton. Each new position of the proton creates a different resistance state, which creates an information storage site called a memory state. Multiple electric pulses create a branch made up of memory states.

"We can build up many thousands of memory states in the material by taking advantage of quantum mechanical effects. The material stays the same. We are simply shuffling around protons," Ramanathan said.

Through simulations of the properties discovered in this material, the team showed that the material is capable of learning the numbers 0 through 9. The ability to learn numbers is a baseline test of artificial intelligence.

The demonstration of these trees at room temperature in a material is a step toward showing that hardware could offload tasks from software.

"This discovery opens up new frontiers for AI that have been largely ignored because implementing this kind of intelligence into electronic hardware didn't exist," Ramanathan said.

The material might also help create a way for humans to more naturally communicate with AI.

"Protons also are natural information transporters in human beings. A device enabled by proton transport may be a key component for eventually achieving direct communication with organisms, such as through a brain implant," Zhang said.

Although many questions remain to be answered, it looks as if the dream of a hydrogen-boron fusion reactor has a serious chance of becoming a reality.

Hora has put forward a roadmap of research and development aimed at building a prototype hydrogen-boron power plant over the next 8-10 years. This prototype would be much smaller and far simpler to build and operate than ordinary nuclear plants, and poses no significant safety issues. According to Hora the price tag would be about $80-100 million. That is peanuts compared with the cost of building a prototype for a new fission reactor design.

15 May 2020 Sydney - Light is emerging as the leading vehicle for information processing in computers and telecommunications as our need for energy efficiency and bandwidth increases.

Already the gold standard for intercontinental communication through fibre-optics, photons are replacing electrons as the main carriers of information throughout optical networks and into the very heart of computers themselves.

However, there remain substantial engineering barriers to complete this transformation. Industry-standard silicon circuits that support light are more than an order of magnitude larger than modern electronic transistors. One solution is to 'compress' light using metallic waveguides - however this would not only require a new manufacturing infrastructure, but also the way light interacts with metals on chips means that photonic information is easily lost.

Now scientists in Australia and Germany have developed a modular method to design nanoscale devices to help overcome these problems, combining the best of traditional chip design with photonic architecture in a hybrid structure. Their research is published in Nature Communications.

"We have built a bridge between industry-standard silicon photonic systems and the metal-based waveguides that can be made 100 times smaller while retaining efficiency", stated lead author Dr. Alessandro Tuniz from the University of Sydney Nano Institute and School of Physics.

This hybrid approach allows the manipulation of light at the nanoscale, measured in billionths of a metre. The scientists have shown that they can achieve data manipulation at 100 times smaller than the wavelength of light carrying the information.

"This sort of efficiency and miniaturisation will be essential in transforming computer processing to be based on light. It will also be very useful in the development of quantum-optical information systems, a promising platform for future quantum computers", stated Associate Professor Stefano Palomba, a co-author from the University of Sydney and Nanophotonics Leader at Sydney Nano.

"Eventually we expect photonic information will migrate to the CPU, the heart of any modern computer. Such a vision has already been mapped out by IBM."

On-chip nanometre-scale devices that use metals - known as "plasmonic" devices - allow for functionality that no conventional photonic device allows. Most notably, they efficiently compress light down to a few billionths of a metre and thus achieve hugely enhanced, interference-free, light-to-matter interactions.

"As well as revolutionising general processing, this is very useful for specialised scientific processes such as nano-spectroscopy, atomic-scale sensing and nanoscale detectors", stated Dr. Tuniz also from the Sydney Institute of Photonics and Optical Science.

However, their universal functionality was hampered by a reliance on ad hoc designs.

"We have shown that two separate designs can be joined together to enhance a run-of-the-mill chip that previously did nothing special", Dr. Tuniz stated.

This modular approach allows for rapid rotation of light polarisation in the chip and, because of that rotation, quickly permits nano-focusing down to about 100 times less than the wavelength.

Professor Martijn de Sterke is Director of the Institute of Photonics and Optical Science at the University of Sydney. He stated: "The future of information processing is likely to involve photons using metals that allow us to compress light to the nanoscale and integrate these designs into conventional silicon photonics."

New technique turns junk into valuable graphene

Matt Davis - 31 January, 2020

Afbeelding

Graphene is insanely useful, but very difficult to produce — until now.

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."

What is graphene?
Graphene's value is mainly due to its incredible strength and the wide variety of industrial applications it possesses. This material consists of a single layer of carbon atoms connected to one another by six chemical bonds, creating a lattice that resembles chicken wire.

Not only is graphene extremely useful in scientific experiments due to its high reactivity and strength, it can also be added to all sorts of other materials to improve their strength or to make them more lightweight, such as concrete or metals. It is the most conductive material, making it invaluable for use as a heat sink in, for instance, LEDs or smartphones. It could also be used in battery technology, in paints, in sensors, and many more — there are quite literally too many applications for this material to cover in this article alone.

What is 'flash graphene'?
Despite its high utility, graphene isn't a part of our everyday lives yet. Part of the reason why is because of its prohibitive cost. Graphene is difficult to produce in bulk, with "the present commercial price of graphene being $67,000 to $200,000 per ton," said Tour. Common techniques include exfoliation, in which sheets of graphene are stripped away from graphite, or chemical vapor deposition, in which methane (CH4) is vaporized in the presence of a copper substrate that grabs the methane's carbon atoms, arranging them as graphene.

The new technique, called flash Joule heating, is far simpler, cheaper, and doesn't rely on any hazardous solvents or chemical additives. Simply put, a carbon-based material is exposed to a 2,760°C (5,000°F) heat for just 10 milliseconds. This breaks every chemical bond in the input material. All atoms aside from carbon turn into gas, which escape in this proof-of-concept device but could be captured in industrial applications. The carbon, however, reassembles itself as flakes of graphene.

What's more, this technique produces so-called turbostatic graphene. Other processes produce what's known as A-B stacked graphene, in which half of the atoms in one sheet of graphene lie over the atoms of another sheet of graphene. This results in a tighter bond between the two sheets, making them harder to separate. Turbostatic graphene has no such order between sheets, so they're easier to remove from one another.

The most obvious use case for what the researchers have termed "flash graphene" is to use these graphene flakes as a component in concrete. "By strengthening concrete with graphene," said Tour, "we could use less concrete for building, and it would cost less to manufacture and less to transport. Essentially, we're trapping greenhouse gases like carbon dioxide and methane that waste food would have emitted in landfills. We are converting those carbons into graphene and adding that graphene to concrete, thereby lowering the amount of carbon dioxide generated in concrete manufacture. It's a win-win environmental scenario using graphene."

Concrete is a major application for this material, one that would both be economically and environmentally sound, but many others exist too. As this method and others for producing graphene in bulk mature, we can hope to see a future with increasingly stronger, more lightweight, more advanced, and less environmentally destructive materials and technologies.

by Kim Martineau, Massachusetts Institute of Technology, April 30, 2020

As more artificial intelligence applications move to smartphones, deep learning models are getting smaller to allow apps to run faster and save battery power. Now, MIT researchers have a new and better way to compress models.

It's so simple that they unveiled it in a tweet last month: Train the model, prune its weakest connections, retrain the model at its fast, early training rate, and repeat, until the model is as tiny as you want.

"That's it," says Alex Renda, a Ph.D. student at MIT. "The standard things people do to prune their models are crazy complicated."

Renda discussed the technique when the International Conference of Learning Representations (ICLR) convened remotely this month. Renda is a co-author of the work with Jonathan Frankle, a fellow Ph.D. student in MIT's Department of Electrical Engineering and Computer Science (EECS), and Michael Carbin, an assistant professor of electrical engineering and computer science—all members of the Computer Science and Artificial Science Laboratory.

The search for a better compression technique grew out of Frankle and Carbin's award-winning Lottery Ticket Hypothesis paper at ICLR last year. They showed that a deep neural network could perform with only one-tenth the number of connections if the right subnetwork was found early in training. Their revelation came as demand for computing power and energy to train ever larger deep learning models was increasing exponentially, a trend that continues to this day. Costs of that growth include a rise in planet-warming carbon emissions and a potential drop in innovation as researchers not affiliated with big tech companies compete for scarce computing resources. Everyday users are affected, too. Big AI models eat up mobile-phone bandwidth and battery power.

The Lottery Ticket Hypothesis triggered a series of mostly theoretical follow-on papers. But at a colleague's suggestion, Frankle decided to see what lessons it might hold for pruning, in which a search algorithm trims the number of nodes evaluated in a search tree. The field had been around for decades, but saw a resurgence after the breakout success of neural networks at classifying images in the ImageNet competition. As models got bigger, with researchers adding on layers of artificial neurons to boost performance, others proposed techniques for whittling them down.

Song Han, now an assistant professor at MIT, was one pioneer. Building on a series of influential papers, Han unveiled a pruning algorithm he called AMC, or AutoML for model compression, that's still the industry standard. Under Han's technique, redundant neurons and connections are automatically removed, and the model is retrained to restore its initial accuracy.

In response to Han's work, Frankle recently suggested in an unpublished paper that results could be further improved by rewinding the smaller, pruned model to its initial parameters, or weights, and retraining the smaller model at its faster, initial rate.

In the current ICLR study, the researchers realized that the model could simply be rewound to its early training rate without fiddling with any parameters. In any pruning regimen, the tinier a model gets, the less accurate it becomes. But when the researchers compared this new method to Han's AMC or Frankle's weight-rewinding methods, it performed better no matter how much the model shrank.

It's unclear why the pruning technique works as well as it does. The researchers say they will leave that question for others to answer.
As for those who wish to try it, the algorithm is as easy to implement as other pruning methods, without time-consuming tuning, the researchers say.

"It's the pruning algorithm from the 'Book,'" says Frankle. "It's clear, generic, and drop-dead simple."

Han, for his part, has now partly shifted focus from compression AI models to channeling AI to design small, efficient models from the start. His newest method, Once for All, also debuts at ICLR. Of the new learning rate method, he says: "I'm happy to see new pruning and retraining techniques evolve, giving more people access to high-performing AI applications."

Dit is een historische vlucht omdat er voor het eerst een bemande ruimtevlucht (naar het ISS, dus in omloopbaan) wordt gemaakt door een commerciële organisatie.

VS lanceert voor het eerst in ruim negen jaar zelf bemande ruimtevlucht

30 mei 2020 21:26

Ruimtevaartbedrijf SpaceX heeft zaterdag om 21.22 uur (Nederlandse tijd) de Crew Dragon-capsule gelanceerd, met twee Amerikaanse astronauten aan boord. Deze lancering is historisch: niet alleen is het de eerste keer sinds 2011 dat Amerikaanse astronauten vanaf Amerikaanse bodem opstijgen, het is ook de eerste commerciële astronautenlancering naar het internationaal ruimtestation (ISS) ooit.

Het was nog even spannend of de missie door zou gaan: net als woensdag dreigde er slecht weer langs de kust van Florida. Eerder zaterdag werd de kans op gunstig weer voor een lancering op 50 procent geschat. Ongeveer drie kwartier voor lancering werd duidelijk dat het weer goed genoeg was verklaard voor lancering.

Astronauten Bob Behnken en Doug Hurley werden rond 18.00 uur naar lanceercomplex 39A gebracht, op de lanceerbasis Kennedy Space Center bij Cape Canaveral in de Amerikaanse staat Florida. Rond 19.20 uur werd het luik van de Dragon-capsule achter de astronauten gesloten.

Na ongeveer twee uur werden de motoren van de Falcon 9-raket ontstoken en verlieten Behnken en Hurley de aarde. Ongeveer tien minuten na de lancering landde de draagraket van deze missie op het drijvende landingsplatform "Of Course I Still Love You".

Lancering moest woensdag plaatsvinden
Eigenlijk had de lancering afgelopen woensdag plaats moeten vinden. Vanwege slecht weer werd de missie echter uitgesteld. De missieleiding vond het te risicovol om de lancering door te zetten. Ongeveer een kwartier voor het opstijgen werd het commando gegeven om te stoppen.

De lancering hoort bij het Commercial Crew-programma van NASA, waarbij de organisatie lanceercontracten af heeft gesloten met de commerciële partijen SpaceX en Boeing. De astronautencapsule van Boeing laat nog op zich wachten, een test met deze capsule afgelopen december mislukte doordat deze niet het ISS kon bereiken.

Dragon meert na ongeveer 19 uur aan bij ISS
Behnken en Hurley moeten ongeveer negentien uur doorbrengen in de capsule, totdat zij kunnen aanmeren bij het ISS. Dit zou nog eerder of later kunnen gebeuren, afhankelijk van hoe goed alles gaat en of NASA en SpaceX nog extra controles uit willen voeren.

Zodra de Dragon aanmeert bij het ISS, gaan Behnken en Hurley aan boord en blijven ze voor 30 tot 119 dagen aan boord. Dat hangt af van het werk dat ze aan boord moeten gaan doen. Na 119 dagen zouden de zonnepanelen van de Dragon mogelijk aangetast kunnen worden.

Dragon vertrekt vanaf zelfde platform als maanastronauten
Lanceercomplex 39A heeft veel historische waarde voor de Amerikaanse ruimtevaart. De Apollo-astronauten die in de jaren zestig en zeventig voet zetten op de maan, vertrokken vanaf dit complex. Later vertrokken ook spaceshuttles vanaf dit platform, waaronder de laatste spaceshuttlemissie ooit: STS-135. Sindsdien leaset SpaceX, het bedrijf van Tesla-topman Elon Musk, het platform en heeft het vanaf complex 39A meerdere eigen raketten de ruimte ingebracht.

Astronaut Doug Hurley was crewlid van STS-135 en dus een van de laatste Amerikanen die vanaf 'eigen' bodem naar het ISS werd gebracht. Zaterdag is hij een van de eersten geworden die weer vanuit de VS naar de ruimte gaat, en een van de eersten die met een commerciële capsule naar het ISS afreist.

Met het succes van de lancering zijn de Verenigde Staten en Rusland de enige landen die actief astronauten naar de ruimte kunnen vervoeren. China werkt zelf ook aan een ruimtevaartprogramma voor astronauten.
