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?

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

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.

Early SpaceX Starship Will Stay as Moon Bases

Brian Wang | June 10, 2020

Elon has tweeted out that early Starships will stay on the moon as part of moon base alpha.

The SpaceX plan is what Nextbigfuture described in last months article “A Sky Full of Starships”.

The SpaceX Starship will have six Raptor engines but will still be larger and cheaper than the external fuel tanks of the Space Shuttle. Elon Musk has a goal of building Starships for $5 million.

If the steel and salaries are half of the total cost of the rockets then the unit costs at different production levels would be:

Two Starships per month would mean $37 million per Starship
One Starship per week would mean $21 million per Starship
Two Starship per week would mean $13 million per Starship

Elon Musk has tweeted out modifications for the SpaceX Starship that will be used for moon landings.

The XGC-S code is opening 'a big window' for nuclear fusion research by helping train simulators.

Researchers from the US Department of Energy (DoE) and the Princeton Plasma Physics Laboratory (PPPL) have demonstrated that an advanced computer code could help design much more efficient and better nuclear fusion reactors.

Nuclear fusion is an attempt to harness the power of the sun in a reactor, potentially providing near limitless, cheap and clean energy. It is often described as the 'holy grail' of physics.

Now, writing in Physics of Plasmas, the PPPL and DoE researchers said that this code, dubbed XGC-S, will greatly benefit the design of stellarators – one of a fusion reactor's key components.

This twisting magnetic coil is essential to trapping hot, charged plasma gas, but it must be precisely engineered to prevent heat from escaping the plasma core where it stokes the fusion reactions.

"The main result of our research is that we can use the code to simulate both the early, or linear, and turbulent plasma behaviour in stellarators," said Michael Cole, lead author of the paper.

"This means that we can start to determine which stellarator shape contains heat best and most efficiently maintains conditions for fusion."

'A really important development'

In testing, the researchers simulated the behaviour of plasma inside fusion machines shaped like doughnuts, but with pinches and deformations that make the device more efficient, a kind of shape known as quasi-axisymmetric.

By using XGC-S, the simulations showed that a type of disturbance limited to a small area can become complex and expand to fill a larger space within the plasma. This makes the new code substantially more accurate than what was previously possible.

David Gates, head of the Department of Advanced Projects at PPPL, said: "I think this is the beginning of a really important development in the study of turbulence in stellarators. It opens up a big window for getting new results."

They now plan to modify XGC-S further to create an even clearer picture of how turbulence affects heat leakage in a reactor.

Cole added: "Once you have an accurate code and a powerful computer, changing the stellarator design you are simulating is easy."

Israeli-made Flying Cars May be Floating into our Future

By Brian Blum, ISRAEL21c | Jul 5, 2020

Afbeelding

Yavneh-based Urban Aeronautics is adapting its Cormorant unmanned drone to be a kind of Uber of the air, starting with emergency services.

For nearly 60 years, the dream of flying cars that many Baby Boomers grew up on while watching TV’s George Jetson jet around the skyways has remained unfulfilled.

But the dream is still alive. A dozen startups around the world are developing VTOLs (“vertical takeoff and landing”) – the technical term for flying cars.

One of the most intriguing of those companies is right here in Israel. Yavneh-based Urban Aeronautics is adapting its Cormorant unmanned drone to be an eventual “Uber of the air.”

Urban Aeronautics’ CityHawk will have two features that make it stand out from the flying crowd.

First, the CityHawk won’t have wings or external rotors. Urban Aeronautics has spent the last decade and a half perfecting an internal propeller system called Fancraft (named after the large fans at the front and rear of the aircraft) that is safer for passersby and takes up much less space.

Second, the CityHawk will be about the size of a large SUV so that it can land on a sidewalk near your home or office. Alternatively, up to four CityHawks could land on the roof of an office building compared with just a single traditionally sized helicopter.

Emergency Services First
CEO Rafi Yoeli established Urban Aeronautics in 2001 to develop helicopters with internal rotors. It took until 2013 to get the technology to work. The first prototype, now called Cormorant (formerly known as the AirMule) took off in 2015.

Urban Aeronautics has two divisions. Tactical Robotics develops unmanned aircraft mainly used in defense, agriculture, cargo transport and power line maintenance. Metro Skyways develops manned craft like the CityHawk.

The Cormorant and the CityHawk are essentially the same. The Cormorant can carry up to 1,400 pounds of cargo while the CityHawk is being designed with seats for five passengers and the pilot.

Yoeli tells ISRAEL21c that the first deployment of the CityHawk will probably be for emergency services.

“With such a small physical footprint, they serve a critical need: the ability to land anywhere,” he says. “You can bring a doctor directly to a patient or rescue a patient. Helicopters today often must land a kilometer a way, then the medical team runs through the streets. A lot of time is lost.”

In June, Urban Aeronautics signed an agreement with Silicon Valley-based HyPoint to incorporate the latter’s hydrogen fuel-cell technology into the CityHawk.

The Cormorant is powered by standard jet fuel. Hydrogen is more environmentally friendly and packs more bang for the buck, boosting the distance an aircraft can operate by 300 percent over gasoline.

With hydrogen power, the next-generation Cormorant is intended to travel for 100 miles before refueling (depending on weight) at a speed of up to 125 miles per hour. The CityHawk will get up to 200 miles on a tank.

Fuel Cells
Fuel cells convert the chemical energy of a fuel – in this case, hydrogen – and an oxidizing agent (often oxygen, drawn from the atmosphere) into electricity. The only residue is pure water vapor.

Other “flying cars” are trying to incorporate lithium-based electric batteries – similar to the type found in a Tesla. Yoeli thinks that’s a mistake.

“A kilogram of battery has just 5% the equivalent amount of energy as hydrogen fuel cells, plus it’s not 100% sustainable like hydrogen,” he says.

We asked Yoeli why, if hydrogen is so much better, battery-powered electric cars are all the rage these days.

“Hydrogen was tried two decades ago, but it was to power normal internal combustion engines,” he explains. Today, with the advent of fuel cells, the hydrogen goes “into a solid-state box and electricity comes out the other side.”

In this case, modern electric cars can have electric engines even if the fuel source is hydrogen. The Honda Clarity and Toyota Mirai are examples. The same will be true with the CityHawk, which is actually an “eVTOL” – an electric VTOL – because its engine is all electric.

Hydrogen can be refueled in minutes rather than hours for batteries. And hydrogen tanks are lighter than electric batteries. When it comes to flying, every kilo saved is critical.

“If you have a one-ton helicopter and you shave off 70 kilograms, you can carry another ticket-buying passenger,” Yoeli says. “Weight can make or break an aircraft design in terms of useful payload and range.”

Ticket to Ride
The question that readers are undoubtedly asking by now is: When can I ride in an Uber of the air?

The answer: Not until closer to the end of the decade.

“The CityHawk is not in service yet,” Yoeli admits. “We still need to design and build it.” The Cormorant, upon which the CityHawk is based, won’t be ready for another three years.

While a working Cormorant demo has made 300 flights already, “it’s not a production aircraft, it’s a one-off.”

The CityHawk “will be ready two years later,” he adds. “We’re talking 2028 or 2030.”

The lengthy process of applying for and receiving FAA certification alone could take five years. “We’re not in a race,” Yoeli stresses.

Meanwhile, the 20-person company will be raising additional rounds as its aircrafts move toward commercialization. And there are key strategic partnerships to ink. In addition to HyPoint, Urban Aeronautics has agreements with Boeing, with the French manufacturer Safran Helicopter Engines, and with Asian mobility service Ascent.

“We won’t stay 20 people in Yavne,” Yoeli predicts.

Will we eventually see pilotless air taxis, similar to self-driving cars? Yoeli isn’t banking on it.

When you’re driving on the road, “if there’s a problem, you can always stop the car and the driver will continue if needed. You can’t do that in the air.”

24-06-2020, Redactie "Executive People"

De Fugaku-supercomputer die door het Japanse Riken-instituut in gebruik is genomen, is meteen de snelste ter wereld. Het is voor het eerst dat een systeem met ARM-processoren bovenaan de lijst staat.

De Fugaku supercomputer is gebouwd met A64FX-processors van Fujitsu en heeft 7,3 miljoen ARM-cores aan boord. Daarmee haalt het 512 petaflops. Die snelheid plaatst de computer meteen bovenaan de top 500 van de krachtigste supercomputers ter wereld. Het systeem stoot daarmee de Amerikaanse Summit van de troon. Die supercomputer, opgebouwd uit IBM Power9-cpu's met Nvidia GV100-accelerators, haalt tot 200 petaflops. De Fugaku computer verbruikt wel drie keer zoveel stroom als de Summit. Bedoeling van de supercomputer Japan is om rekenwerk te doen voor onderzoek, onder meer naar covid-19. Het systeem zou oorspronkelijk in 2021 ingehuldigd worden, maar door de coronacrisis is die datum vervroegd.

Het is de eerste keer dat er een ARM-systeem bovenaan de lijst staat. De meeste supercomputers worden nu gebouwd met x86-microprocessors, gebaseerd op architectuur van Intel. Enkele supercomputers die gepland zijn voor volgend jaar, en die nog sneller zijn dan Fugaku, gebruiken dat Intel-systeem ook. ARM-architectuur beleeft momenteel wel een oplevering in populariteit, nu ook Apple besloten heeft zijn chips daarop te baseren.

The Pentagon Is Quietly Working on a Military Space Station Outpost

July 17th 20 - Victor Tangermann

Afbeelding

The Department of Defense has quietly awarded a contract for the Sierra Nevada Corporation to turn its Shooting Star cargo spacecraft into a small experimental space station, The Drive reports.

The defense contractor has been developing the spacecraft since 2016 as a way to resupply the International Space Station under NASA’s Commercial Resupply Services program.

The craft is 16 feet long and is designed to carry 10,000 pounds of cargo into orbit. Six thrusters allow it to adjust its orbit independently. SNC’s Dream Chaser, a Space Shuttle lookalike[/url], is designed to carry the capsule into orbit and even as far as Moon’s orbit.

The company is hoping to turn the Shooting Star into a small space station meant for “space assembly, microgravity, experimentation, logistics, manufacturing, training, test and evaluation,” according to a press release.

“We’re excited by the multi-mission nature of Shooting Star,” SNC CEO Fatih Ozmen said in the press release. “The possible applications for Shooting Star are really endless.”

Free-Flying Destination
The company is already looking at sending such a space station to orbits far beyond the ISS, including geosynchronous Earth orbits, and even cislunar orbits.

“We are proud to offer our transport vehicle to DoD as a free-flying destination for experimentation and testing, expanding beyond its current payload service capabilities for Dream Chaser cargo missions,” said senior vice president of strategy for SNC’s Space Systems Steve Lindsey.

While initial Shooting Star capsules will be unmanned, The Drive suggests the Pentagon may be interested in moving on using it as a manned outpost as well.

Published: 15 July 2020

Dr Ioannis Zeimpekis co-led the research in the Mountbatten cleanroom complex
Researchers from the University of Southampton have demonstrated a new material family that will revolutionise optical circuits to replace parts of traditional electronic hardware.

The materials allow rapid reversible switching between two states, known as phase change, which has previously been limited to electronic circuits as standard commercially available materials suffer from large optical losses.

Scientists from the Quantum, Light and Matter group and Optoelectronics Research Centre (ORC) have designed the phase change materials to exhibit no loss of light at telecommunication wavelengths and be switched with very low power.

The technology is compatible with existing silicon photonic circuits and opens the door for more advanced applications. Researchers have published their findings in Advanced Functional Materials.

Lead authors Dr Matthew Delaney and Dr Ioannis Zeimpekis pinpointed the material structure and composition to enable high transparency while exhibiting low power modulation of light. They found that the new composition has 100 times less loss than the current state-of-the-art optical materials.

Their material was deposited on top of optical chips, where a short laser pulse was used to crystalize the material and change the phase of the guided light. The researchers demonstrated this property reversibly thousands of times. Importantly, the material remembers its last state without any applied signals, leading to large potential power savings.

Professor Otto Muskens, Head of the Integrated Nanophotonics group, says: "This new technology will simplify and enable newly emerging applications such as solid-state LiDAR, quantum and neuromorphic computing that are currently limited by the performance of the existing materials.

"Neuromorphic and programmable photonics are set to revolutionise the industry as they offer new paradigms for data processing going far beyond existing hardware. Quantum optical circuits are on the horizon and ultralow loss components are needed to make the next step in controlling and routing quantum information."

Traditional communication electronics consume a huge proportion of their energy at the interconnection level, and their bandwidth is directly limited by the communication length. Using photons instead of electrons alleviates these shortcomings.

Phase change photonics offer much promise for the future of integrated silicon photonic circuits, with some of the world’s largest companies competing in the race for fully integrated optical solutions. However, the high absorption losses in current commercially available materials have prevented their use in larger photonic systems such as in interconnects between data servers, where the photonic technology is projected to excel.

Professor Dan Hewak, ORC co-author who has spent decades on phase change materials, says: "This is a significant breakthrough for optoelectronics. Our team has now demonstrated a material which bridges the gap between electronics and photonics and we expect to see further advances resulting from their discovery."

The new phase change family has been designed as part of a series of research projects funded by the Engineering and Physical Sciences Research Council (EPSRC), including ChAMP, the Manufacturing and Application of Next Generation Chalcogenides (EP/M015130/1), Cornerstone (EP/L021129/1), The Physics and Technology of Photonic Metadevices and Metasystems (EP/M009122/1) and Nanostructured photonic metamaterials (EP/G060363/1). The new materials reside within the chalcogenide family as they combine antimony and sulfur or selenium.

The team is currently working to implement more photonic circuit components with the aim to design a neuromorphic computing photonic chip with in-memory computing capabilities. It is expected that this method will replace current technologies within the next couple of years enabling a leap forward for the technology of photonic computing.

Het is niet ondenkbaar dat ook landen als Turkije, Iran en Indonesië in de nabije toekomst (in het komende decennium) in staat geraken om raketten naar Mars te sturen.

Zie bijvoorbeeld :

Erdogan's Turkey's unbridled space ambitions

Iran places military satellite in orbit

Indonesian space agency dreams of launching rocket

Dus mogelijk wacht ons straks een strijd tegen de islam op Mars.

By Alex McFarland, July 17, 2020

Engineers at MIT are working toward giving robots the ability to follow high-level commands, such as going to another room to retrieve an item for an individual. In order for this to be possible, robots will need to have the ability to perceive their physical environments similar to the way we humans do.

Luca Carlone is an assistant professor of aeronautics and astronautics at MIT.

"In order to make any decision in the world, you need to have a mental model of the environment around you," Carlone says. "This is something so effortless for humans. But for robots it's a painfully hard problem, where it's about transforming pixel values that they see through a camera, into an understanding of the world."

To take on this challenge, the researchers modeled a representation of spatial perception for robots based on how humans perceive and navigate their physical environments.

3D Dynamic Scene Graphs
The new model is called 3D Dynamic Scene Graphs, and it enables a robot to generate a 3D map of its physical surroundings, including objects and their semantic labels. The robot can also map out people, rooms, walls, and other structures in the environment.

The model then allows the robot to extract information from the 3D map, information that can be used to locate objects, rooms, and the movement of people.

"This compressed representation of the environment is useful because it allows our robot to quickly make decisions and plan its path," Carlone says. "This is not too far from what we do as humans. If you need to plan a path from your home to MIT, you don't plan every single position you need to take. You just think at the level of streets and landmarks, which helps you plan your route faster."

According to Carlone, robots that rely on this model would be able to do much more than just domestic tasks. They could also be used for high-level skills and work alongside people in factories, or help locate survivors of a disaster site.

Current Methods vs New Model
The current methods for robotic vision and navigation mainly focus on 3D mapping that allows robots to reconstruct their environment in three dimensions in real-time, or semantic segmentation, which happens when robots classify features in the environment as semantic objects, like a car versus a bicycle. Semantic segmentation is often done on 2D images.

The newly developed model of spatial perception is the first of its kind to generate a 3D map of the environment in real-time and label objects, people, and structures within the 3D map at the same time.

In order to achieve this new model, the researchers relied on Kimera, an open-source library. Kimera was previously developed by the same team to construct a 3D geometric model of an environment, while at the same time encoding what the object likely is, such as a chair versus a desk.

"Like the mythical creature that is a mix of different animals, we wanted Kimera to be a mix of mapping and semantic understanding in 3D," Carlone says.

Kimera used images from a robot's camera and inertial measurements from onboard sensors to reconstruct the scene as a 3D mesh in real-time. In order to do this, Kimera utilized a neural network that has been trained on millions of real-world images. It could then predict the label of each pixel and use ray-casting to project them in 3D.

Through the use of this technique, the robot's environment can be mapped out in a three-dimensional mesh where each face is color-coded, identifying it as a part of objects, structures, or people in the environment.

3D Mesh to 3D Dynamic "Scene Graphs"
Because the 3D semantic mesh model requires a lot of computational power and is time-consuming, the researchers used Kimera to develop algorithms that resulted in 3D dynamic "scene graphs."

The 3D semantic mesh gets broken down into distinct semantic layers, and the robot is then able to view a scene through a layer. The layers go from objects and people, to open spaces and structures, to rooms, corridors, halls, and whole buildings.

This layering method allows the robot to narrow its focus rather than having to analyze billions of points and faces. This layering method also allows the algorithms to track humans and their movement within the environment in real-time.

The new model was tested in a photo-realistic simulator that simulates a robot navigating an office environment with moving people.

"We are essentially enabling robots to have mental models similar to the ones humans use," Carlone says. "This can impact many applications, including self-driving cars, search and rescue, collaborative manufacturing, and domestic robotics.

Carlone was joined by lead author and MIT graduate student Antoni Rosinol.

"Our approach has just been made possible thanks to recent advances in deep learning and decades of research on simultaneous localization and mapping," Rosinol says. "With this work, we are making the leap toward a new era of robotic perception called spatial-AI, which is just in its infancy but has great potential in robotics and large-scale virtual and augmented reality."

The research was presented at the Robotics: Science and Systems virtual conference.
