Scottish research Institute for marine energy (EMEC) was the first to produce hydrogen, using the energy of the tides. Located off the coast of the Orkney Islands, the station is going to use hydrogen fuel as an alternative fuel for ferries.
Using the prototype converters tidal energy electrolyser ITM Power is able to separate water into its components, hydrogen and oxygen. The device produces 220 kg of hydrogen every 24 hours, it can store up to 500 kg.
The primary purpose of the acquisition apparatus for electrolysis was the solution to the problem of storing energy on Orkney, EMEC but now going to explore the possibility of developing a hydrogen economy in the region. According to the Director of the centre Neil Kermode, clean hydrogen fuel can, with time, replace fuel for local cars, trucks and ferries.
The main consumer of hydrogen fuel will be the project Surf N Turf, which is going to use two sources of renewable energy: wind turbines on the coast of the island Edey and EMEC tidal station at 500 kW, splitting the water. Hydrogen stored as a compressed gas, and then transported by land to the port Croall, the capital of the Orkney Islands. There they run ferries that transported peat, reports The Engineer.

The interface allows to translate brain activity in real time
Students of the University of the Witwatersrand in South Africa has developed an interface that allows to connect the human brain to the Internet of things in real time. As reported on the website of the University, the development was named Brainternet.
Brainternet works on the basis of the transformation of brain signals in the "direct brain stream", which is then fed to a small computer Raspberry Pi. The data is then transferred to the web site through which anyone can monitor the brain activity of another person.
For registration of brain activity developers used a 14-channel EMOTIV EPOC EEG. It records the electrical activity of the brain in 14 points located in different zones of the cerebral cortex: frontal, temporal, parietal and occipital lobes. To collect data using a wireless plastic "helmet" with electrodes that person to perform everyday tasks. The collected data is processed using an algorithm created on the basis of a support vector machine, one type of supervised learning. Analyzing incoming information, the algorithm connects specific patterns of electrical brain activity with certain types of action. For example, the system can determine when a person goes and when.
One of the objectives of the project — the creation of a system of visualization of brain activity during different actions. The authors Brainternet demonstrated how to change the indicators of electrical activity at multiple points in the frontal lobes of the cortex when lifting the hands.

Scientists from Brunel University in London believe that men are more likely to Troll users of social networks than women. According to the study, the average portrait of the Troll-Narcisse out of 570 investigated social media profiles in 85% of cases is a white working male whose profile data contains at least about 304 online friends, reports life.ru.
According to researchers, the solvent narcissism of white middle-aged men is observed more often than the same behavior of women of the same age and social level. However, it should be noted that the profile study, which resulted in the writing of a user to identify a Troll is a narcissist in social networks, it was compiled exclusively by women. In the work participated Nelli Ferenczi College goldsmiths, University of London, Tara Marshall and Kathrine bejanyan from Brunel University in London.
The reasons of such behavior of men in social networks, scientists have called the previously known features associated with gender differences: men's need to dominate and prove their innocence.
