Scientists from Massachusetts have learned to convert carbon dioxide into fuel

CO2

To date, there are at least several technologies for ” storing ” atmospheric CO2. However, researchers at the Massachusetts Institute of Technology (MIT) went further. They have learned how to convert the carbon dioxide released from fuel combustion to TPP into raw materials, which can then be processed into fuel for cars and aircraft, as well as into other substances.

Dr. Xiao Yoo Woo, together with Ahmed Guniem and engineering professor Ronald Crane, developed a membrane system based on the compounds of lanthanum, calcium and iron oxide, through which carbon dioxide (CO 2) is converted to monoxide-CO.

The separation process itself occurs at a temperature of 990 ° C. It is very important that the SB continue its “path” through the membrane until it is on the opposite side. This can be achieved with the help of vacuum, but this requires a lot of energy.

An alternative to costly technology can be the use of a stream of hydrogen or methane, since these substances are easily oxidized and do not require a pressure difference for “pumping” oxygen atoms through the membrane.

The resulting carbon monoxide can be used directly as a fuel, and in combination with hydrogen, water or a mixture thereof, to produce a liquid hydrocarbon fuel and other valuable chemical products, methanol, synthesis gas, etc.

Unico

 

It is not known for certain whether the Unico device exists in reality, or it is only a figment of the imagination of designers and engineers. However, the start-up of the fastest toothbrush in the world has successfully collected ten times the amount of requested funds and from day to day must send it to production.

The developers of the gadget claim that it completely cleans all teeth in 1.87 seconds, but according to the results of tests on living people, the time was artificially slowed down by half. Otherwise, people do not have time to understand what happened, although there is nothing complicated in the process. Micropumps feed the cleaning agent onto rotating brushes, which are installed along the teeth.

Unico

The Unico device resembles a boxing cap which must be put on the teeth before work. Then you need to connect an external battery, select the mode and press the button. In the intervals between work Unico must be kept in a sterilizing box with ultraviolet radiation, which looks no less stylish than the docking station for the iPhone.

The authors of the startup promise models for four different sizes of jaws and an application for a smartphone to fine tune the speed and duration of cleaning. The price of one copy will be $ 118, mass production will begin in December 2017, and the sale of “toothbrushes” Unico will arrive in the early days of next year.

FM-2022

The construction of giant stadiums for the World Cup costs billions of dollars, while many of them after the end of the events remain without “work.” With this in mind, the owner of the World Cup in 2022 – Qatar introduced a project of a modular stadium that will solve this problem in an unusual way: after mundialya it can be dismantled and transported to another location and reassembled, but perhaps in a different configuration.

The stadium project Ras Abu Aboud was developed in the design studio Fenwick Iribaren Architets (Spain). The construction is unique primarily because part of its construction consists of sea containers, where all the property of the stadium will be stored after its dismantling in case of moving to another place.

FM-2022

The stadium-transformer can be recreated in several versions – in the original, as well as in the form of smaller sports facilities or cultural centers. The stadium is designed for 40,000 spectators and will be ready by 2020. Organizers of the World Cup-2022 hope that the concept of the stadium Ras Abu Aboud will be further developed, as the design of sports facilities of the future.

Boat Nauti Craft

Those who suffer from seasickness seem to have the opportunity to go to sea without fear of its unpleasant consequences. Company Nauti Craft, located in Dunsboro, Western Australia, has developed a boat, which otherwise can not be called “sea buggy”. It is able to overcome high waves at high speed with the help of a hydraulic suspension, which performs the function of a shock absorber, which significantly reduces the rolling.

The special design made it possible to make the upper part of the case independent of the bottom. The hydraulic “layer” extinguishes the vibrations from collision of the catamaran part of the vessel with the waves and does not transfer them to the deck.

Boat Nauti Craft

Initially, the boat was intended for servicing remote wind farms. However, his commercial prospects became very obvious. Increased stability in rolling conditions in combination with high speed and comfort make it attractive, both in military and civil spheres.

Similar suspension schemes were used by Mitsubishi Motors in the Dakar rally and the Citroen team in the World Rally Championship.

A new and elusive virus is robbing Russian ATMs

bankomaty-pod-ugrozoj.jpg

ATMs under threat

It turns out that in order to thoroughly gut the ATM it is not necessary to install skimmers on it, to blow it up or steal it with a steel cable tied to the car. The Russian banking community again faced the next cyber threat.

The new virus is aimed at stealing money not from customers trying to withdraw money, but from the ATM itself. The malicious code is introduced into the operating system of the ATM through infected computers of specialists of the internal network of banks.

The most horrible and interesting thing is that the virus is almost imperceptible. It is incorporeal, since it is devoid of a file body, therefore, even the most advanced antivirus programs do not respond to it. Taking advantage of its impunity, the virus, in fact, receives a “permanent residence permit” from the ATM.

And then begins in the full sense of the word robbery in broad daylight. Attackers, knowing a special code, withdraw all the contents of the so-called first cassette from the ATM, where the largest denominations of 1 or 5 thousand rubles are located.

While specialists in the field of banking cybersecurity are at a loss and are considering how to protect themselves from this scourge.

The secret of good champagne: the more bubbles, the more delicious it is

uzory-iz-puzyrkov-g1W6.jpg

Bubbles of Champagne

The presence of a constant stream of small bubbles rising upwards is considered to be a sign of high-quality champagne. However, recent studies have made adjustments to this statement. According to them, it is bubbles of a large size that have a beneficial effect on the taste of the famous New Year’s drink.

It is worth recalling that the bubbles are dissolved carbon dioxide, which is formed in the wine during the second stage of fragmentation in the clogged bottle. When the bottle is opened, the gas escapes outward with a characteristic cotton, and sometimes in the form of a jet of foam.

Scientists from the University of Reims, led by Professor Gerard Liger-Beler, found that the presence of large bubbles of about 3.4 mm on the surface dramatically increases the release of aerosols. This means that important aromatic compounds, giving the champagne a unique taste and smell, “hit” in the nose with the first gulp.

Patterns from bubblesLaser tomography of motion of bubbles

On average, there are about a million bubbles in the glass . Using high-speed imaging and imaging, scientists studied their behavior. At the moment when the bubble bursts, a cavity is formed that stretches and deforms adjacent bubbles, creating a pattern similar to flower petals.

According to Professor Liger-Beler, the size of the bubbles can vary from 0.4 to 4 mm in diameter. Their size can be influenced by the viscosity of the drink, the shape and size of the glass. It was found that at a bubble size of 1.7 mm radius, the greatest number of drops emitted to the surface is formed.

The results of the research, according to Liger-Beler, will help winemakers significantly improve the taste of sparkling wines.

Keyboard

British scientists have presented their new development – a unique wireless keyboard . The novelty can easily pretend to be the thinnest keyboard in the world.

Specialists Cambridge company CSR showed a prototype of the thinnest keyboard, which can be used with both tablets and computers. As already mentioned, the uniqueness of the novelty lies in the thickness of its body, which is only half a millimeter. It includes a printed circuit board and a Bluetooth 4.0 chip and is covered with a thin touch layer. The response time of the new keyboard is 12 ms.

Keyboard

A thin keyboard takes up very little space and, if desired, it can even be folded or rolled into a tube.

As the creators note, it’s still too early to talk about the appearance of a new device on the market. Now it is only a prototype, which will be officially presented at the international exhibition IFA 2013, which will be held on September 5 to 6 in Berlin.

Set LaneCruise will turn any car into an unmanned vehicle

x-matik-yroB.jpg

X-Matik

Canadian start-up X-Matik presented its development – robotization module for conventional cars. It consists of controllers for the steering wheel and pedals, a camera and a computer block. This set is enough to endow the machine with autopilot functions without a deep and costly upgrade.

In the company X-Matik claim that their development is universal, compatible with a minimum of two dozen popular models of cars and allows a person to retain control of the machine. This is a stripped-down version of the autopilot, it can not drive completely independently and can not work with navigation devices either. In fact, it’s the assistant driver – LaneCruise can keep a distance in the flow or follow straight ahead on the markup.

X-Matik

Unlike the current drones, this device uses a simple system of visual recognition of objects, so in the absence of signs or other machines can not drive even an empty intersection. The driver is still fully responsible for the behavior of the car on the road, so you do not get a nap behind the wheel. Maximum – listen to music and drink coffee.

The beta version of LaneCruis will appear in limited access in early 2018, and by the end of 2019 you can expect to see the finished product. The price list is still suspended on $ 1,5-2 thousand, but the option of renting the installation with monthly payment is also considered. While the device will be available only in the North American market.

The deepest fish in the world was found in the Mariana Trench

Tomogram of the Mariana Slug with the remnants of his last lunch

A new study of the biosphere of the deepest depression on the planet brought the discovery – scientists found another candidate for the status of the deepest creature. It was dubbed Pseudoliparis swirei and carried to sea slugs or linden. This fish looks like a very strange tadpole, and for that there are compelling reasons.

The maximum depth of the Mariana Trench reaches 11,000 m, and the new slug fish was found at depths of 8,000 and 8170 m. It was first caught in 2014, but only by now there has been sufficient catch to officially announce the discovery. A total of 37 individuals were sacrificed to science, which were taken literally to pieces – numerous studies were carried out, including DNA analysis and computed tomography.

Pseudoliparis swirei

Surprisingly, the fish of Pseudoliparis swirei, living in a harsh environment at colossal pressure, looks too flimsy and plump. Not an armored monster, not a semi-transparent monster, but an overgrown tadpole – as marine biologists explain, there are no predators at this depth and it does not threaten anything. She is on top of her food chain and feels at ease, all the caught specimens were quite well-fed by the standards of the ocean.

Pseudoliparis swirei are perfectly adapted for life in the Mariana Trench. This geological formation has the shape of a funnel, so the sinking carrion accumulates in one place. There, invertebrates feast on it, and slime devours them. He does not even need scales for protection, it’s the king of the depths! Only small and tied to his kingdom, since more such fish were nowhere to be found.
