The Russians are working on an atomic train

Russians are no longer enough modern trains moving on the magnetic cushion and want to continue to run for the future. They are working on a train powered by a nuclear reactor.

The Russian Federal Atomic Energy Agency, and Russian Railways, have announced joint plans to build a nuclear propulsion train. For now, this is a mere dream, as not only are the costs of this venture known, but the ways in which it is used to protect passengers are unknown, because the reactor is, however, much more dangerous to drive than a normal diesel engine and in the event of a rail disaster, it would be uninteresting.

Nevertheless, the originators claim that this idea is possible, and that such an atomic locomotive could easily be transformed into a mobile power plant, providing energy to saunas, laundries and green homes.

The concept of vehicles powered by nuclear reactors is not new. Ford Motor Company already in 1958 created an atomic car project, driven by a small reactor located in the rear of the vehicle. Of course the car never came into production. It was similar with the design of the atomic vacuum cleaner.

So it seems that the idea of ​​the Russians will end only on the project and we will not hear more of it.…

New shape memory polymer

The University of Rochester researchers have succeeded in creating a completely new polymer that can play an important role in the future in the field of medical applications. The new material has the ability to preserve its shape, but it can also return to its original shape, and the process is activated only by body temperature.

Memory-form materials are not uncommon today, are used in various industries and can be found in sleeping mattresses or headphones. Such material has been developed by scientists from the University of Rochester, but their invention is somewhat more advanced.

The new polymer created by the researchers has quite unusual properties. It can be tampered with, giving a new shape that will be preserved by him. Just touch it to the body, and then the heat will make the material return to its original shape. This is not important, but the fact that it returns huge amounts of stored energy when it returns to its original shape.

There are really many and experiments have shown that at this time the polymer can lift a mass 1000 times its own weight. During one of the tests, a shoelace sized piece was able to carry a liter bottle of water.…

ESA tests the printed antenna to the satellite

3D printing technology makes it possible to produce items that are much more accurate than traditional methods of making them. In addition, the production of more complex objects is much easier, not to mention the lower cost of their production. That is why 3D printers are increasingly being used in the space industry.

The European Space Agency plans to use it to produce components that will significantly improve the process of building satellites in the future and will reduce their costs. Currently in the Dutch Compact Antenna Test Facility in Noordwijk, testing of the first component from a 3D printer is under way, with a new radio antenna, providing satellite communication with the command center.

The antenna, despite its complex geometry, can be printed out in its entirety, eliminating the need for subsequent assembly. Moreover, this also eliminates the potential risk of later problems that may be related to inaccurate assembly of all components.…

Ford cars tested by robots

In 2013, the American company Ford announced the creation of a robot that was designed to test new vehicles and test their behavior in all driving conditions. After two years of construction, it is getting closer to completion, and Autonomous Solutions, Inc. is helping to create it.

Every new model car must go through exhaustive, multi-month tests before it goes into production, in which the vehicle is tested under various road conditions, in burning heat and high temperatures, on slippery and dry surfaces, In other words, you need to make sure that all of its components work properly, will not break down when you leave the living room, and will also manage the slippery road, that is simply eliminating all the weak points.

Nowadays this task is handled by factory drivers, but maybe in a few years, they will replace their robots. Ford engineers, along with Autonomous Solutions, Inc., are designing such a test-driven vehicle to simulate years of use in the real world.

The machine that replaces a human will be able to perform tests without interruption and to do so much more accurately, which during long-term tests of new models will certainly be a much cheaper solution than test drivers.

The test performed by the machine will simulate normal use of the car, and as the Ford engineers say, a few months’ test will be a simulation of a 10-year vehicle operation under standard conditions. This will allow you to assess the life of components and make the necessary adjustments to your car’s design.

The developed robot controls the car in the same way as a man does, ie, turns the steering wheel, uses accelerator pedal, brake and clutch pedal as well as gear lever. With special software, the machine will be able to perform specific tasks by repeating the desired number of steps.…

Quizzes on Facebook threat to privacy?

Many people love playing intellectual and sitting in front of the computer, often looking at Facebook to solve quizzes available there. Experts warn against this form of entertainment, because the applications available there may pose a threat to your privacy by collecting too much information about it.

Comparitech, which has reviewed several popular quiz apps available on a popular social networking site, found that they collect not only our personal information, but also their date and place of residence, education, information about their favorite sites or photos, browser information, language , An IP address, and even a list of friends tied to Facebook. It’s a lot of information for a simple game and so much data is gathering most applications.

Some applications give the user the ability to choose which information they want to share, but in many cases the program does not work properly if we try to restrict access to our data.

The biggest problem, however, is not that applications collect data, but for what they do. For example, the company, the creator of Most Used Words on Facebook, has a record in its rules that gives it the right to use the information even if the user deletes the account. They can also be stored on servers around the world, including in places where there is no legal protection of personal data. Although the company ensures that it will not share your data without informing you, but there is a record in the rules that can be considered as such notification. In other words, the company can freely sell the data to sell to whom it wants.…

Ryanair is testing streaming movies on airplanes

Irish airline Ryanair is testing a brand new service to improve flight comfort by providing entertainment on longer journeys. The new idea is to stream movies and TV programs directly to mobile devices belonging to passengers.

Most airlines have built-in screens built into the seats to keep passengers entertained and do not get bored during long hours. Low cost airlines can not afford such luxury, because for low ticket prices they have to save on everything. This does not mean, however, the need to give up small pleasures.

Most passengers have their own laptops, smartphones or tablets, so Ryanair came up with the idea to stream movies and series to such devices. This is a cheaper solution than screen installation and is equally functional. Moreover, the carrier does not intend to charge any extra fee, which is a very nice surprise. But there is nothing free, so the lines will want to compensate by displaying ads.…

Experimental unit, invisible to radars

Sea Shadow is one of the most exciting floating structures ever built. This experimental machine was supposed to check how much you can hide against the enemy radars. Its construction was commissioned to Lockheed Martin under the supervision of DARPA and US Navy.

The construction of the Sea Shadow unit in practice has tested the possibility of solving the problems of the American leadership at the turn of the 1970s and 1980s with the use of the stealth technology of the F-117 Nighthawk, or possibly the greatest automation of ship handling to reduce the crew needed to a minimum. It also tested how the new hull type will be tested in the ocean.

Completed in 1984, the ship, until 1993, remained a strictly secret project. He has never been officially accepted to service, despite the presence in the US Navy’s records. By the end of his days he remained an experimental unit that was not intended to carry out any mission.

Sea Shadow had nearly 600 tons of displacement, a length of 50 meters, and its engine was able to disperse the unit to 14 knots (26 km / h). The crew was only ten seamen. Its main problem was the very small space reserved for the crew. On board we could find 12 places on bunk beds, microwave, small fridge and a table.…

Microsoft server underwater servers

Large technology companies such as Google, Facebook and Microsoft have to constantly expand their server rooms not only to keep growing their customer data, but also to offer more and more cloud services. The problem, however, is the issue of cooling them, so Microsoft is working on a project called Project Natick, which aims to build server rooms under water.

Gigantic server rooms, consisting of thousands of computers, produce enormous amounts of heat. Delicate electronics does not like high temperatures, so it has to be cooled, and it generates enormous costs. So technology companies are looking for different solutions to provide cheap cooling, and that’s why Facebook built one of these under the Arctic Circle, so that ordinary air is used for cooling.

However, Microsoft has developed a slightly different cooling method. The company, which already owns more than a hundred server rooms scattered all over the world, is planning to go down with them now. Engineers have developed a concept for underwater servers located on the ocean floor and enclosed in sealed capsules, which are naturally cooled through water. Capsules with land would connect properly reinforced optical fibers for data transmission.

What’s more, such a solution would not only cool servers, but also power them, using marine-wave energy systems. And the added advantage of such an idea would be to reduce data delays because containers would be close to residential areas.…
