Most of our readers are familiar with the structure and principles of operation of fire extinguishers. talk About it at school, lectures on civil defense and labor protection, conducted at the industrial enterprises, etc. However, knowing something in theory is not what to be able to use this in practice. In order to bridge the gap between theory and practice, NEC and MX Mobiling Co Ltd has developed a virtual reality system that will allow people to take up training and fire extinguisher to take part in fighting virtual fire, write novostiit System, which was called “Fire Extinguishing VR Experience Simulator”, does not require the use of any special tools. Thus, it can simulate the fire in different places, indoors and outdoors, for example. The system is...

A Group of scientists-astronomers from the University of Oklahoma have discovered a rather rare system consisting of two white dwarf stars SDSS J082239.546+304857.19 and SDSS J104336.275+055149.90, rotating around each other at very close orbits with a period of 40 and 46 minutes. White dwarfs are the remnants after supernova explosions of Sun-like stars within our galaxy, the milky Way galaxy, very often of a binary system consisting of two white dwarfs. But only a small number of such systems of stars are very close to each other. At the same time, the vast majority of binary “dwarf” systems with orbital period less than one hour, was found by a group of astronomers from the University of Oklahoma, led by Machimina a Kylix, write novostiit “short-period...

Famous German company Siemens in 2012 introduced the idea of electrified motorways eHighway. the Hybrid diesel-electric truck when they reached the highway eHighway, raises special pantograph (a device-a current collector) and continues to move only on electricity, charging, in parallel, their batteries. Last year, Siemens built an experimental section of the main eHighway near Stockholm, Sweden. And now is preparing to build a 10-km stretch of the eHighway, which will cover part of the A5 motorway in Germany, write novostiit the construction of the first electrified piece is held with the permission of the administration of the district of Hesse and it, construction must be completed by the end of next year. The beginning section will be located in the...

Modern information processing centers, data centers consume an enormous amount of energy, which leads to high requirements to used in their cooling systems. To solve this problem, the company Kolos plans to build the world's largest center of data storage and processing in the North of Norway, where the cold Arctic climate will create the most efficient cooling system, and the abundance of renewable clean energy will partially solve the problem of energy supply of the servers located in a new datacenter, write novostiit At the time, we told our readers that Microsoft has tried to solve the problem of cooling of information centre, dropping servers on the seabed. However, the climate for the border of the Arctic circle offers more favorable conditions for...

Thanks to the photographers and video operators, making shooting expanses of Land with a helicopter or airplane, there are pictures, recorded from the height of bird flight. Extraordinary, fascinating and beautiful photos often appear before our eyes. For shooting with "sky" use of aircraft is quite expensive. So was invented a compact, functional camera – quadcopter with certain tasks. For each model of the device calculated the weight of an attached camera, set the duration of the flight. the Quadcopter and its functions Customers, from the height of any object or action, today quite a lot. Shooting weddings, commercials, study area with height is considered to be a complex process. Aerial photography with a quadcopter allows you to take pictures or hold...
