Last Tuesday we made a small selection of inexpensive interesting gadgets to which each geek will be glad. The selection was pleasant to much so we decided to continue to share our knowledge in this area and created a selection from 15 interesting things + a bonus. Went.
1. Power Bank on 30000mah which is loaded with the sun of $12.70 (3491 persons liked)
Rosenergoatom started construction of the data-center, largest in the country. Data-center power on completion of construction will make about 80 MW, and the quantity of racks will reach 10000. The data-center is under construction in the Tver region, near the Kalinin NPP. If more precisely, then the station is located in the station satellite town to Udomlya.
Will build a data-center the TsHD Engineering company which ensures "turnkey" functioning, laying power supply, water supply, heating, ventilation and conditioning, plus constructs even roads and other infrastructure facilities. 10% of a data-center will be reserved under needs of Rosenergoatom, and other capacities will be able to lease the third-party companies. Earlier the state company suggested to transfer personal data of Russian-speaking users to the data-center, to communications in entry into force of the federal law on a personal data storage in the territory of Russia.

Formula E and Kinetik 27 of November, 2015 signed the agreement on partnership for the purpose of start of a world pilotless racing series of electric cars. The new championship under the name "Roborace" will provide a platform for a running in of pilotless solutions. Large players from an automobile industry, and also the leading technical universities will take part in it.
The plan consists that Roborace will be race of support of the championship of the Formula E, since a season of 2016-2017. Races will pass before arrivals of the Formula E, on the same routes, in the large cities worldwide (the current calendar of a formula E consists of ten races, the Grand Prix are accepted by such cities as Beijing, Buenos Aires, Paris, Berlin, London and Moscow and dr). Ten commands, everyone with two pilotless cars, will compete in hour race during the whole season. All commands will use identical cars, and competition will consist in the used algorithms of calculations in real time and technologies of artificial intelligence.

Приветствуем вас на страницах блога iCover! Сегодня мы расскажем вам о новой простой и доступной в реализации технологии, позволяющей преобразовать энергию фотонов невидимого инфракрасного света в энергию излучения синего и ультрафиолетового спектра. По мнению авторов разработки, их продукт – многослойная наночастица с уникальными рабочими характеристиками, найдет применение в самых разных областях, начиная с возможности создания более эффективных солнечных преобразователей и элементов систем безопасности — и оканчивая биоимиджингом на принципиально новом уровне…

The electrobicycle in style of a chopper Archont is made to order manually, on a total charge the bike will pass 99 kilometers, and its maximum speed — 80 kilometers per hour. The largest model in length reaches three meters, and its weight makes 55 kilograms.
By the preorder such bike will cost seven thousand American dollars, and later the price will grow to ten and a half thousand.

About seven years ago the U.S. President urged to provide emergence of one million electric vehicles on roads of this country by 2015. Vendors of electric cars received a number of preferences, and electric vehicles had a large number of admirers eventually. And really — there are no emissions, it is not necessary to be spent for gasoline or diesel fuel. For the owner, it seems, one pluses. At the same time now a number of large car makers already let out or are only going to release own electric vehicles. And we do not remember Tesla Motors from it more yet, than ambitious plans.
So how many now electric vehicles on roads of the same America? It appears, not one million, and not two million, but only 330 thousand. What? Why so? It appears it is not the high price of separately taken electric vehicle or other reasons. The main stumbling block — car dealers. They just do not want to sell electric cars, enthusiasm at dealers about it much less, than at the others.

There came the winter if suddenly who did not notice, and it means that in an hour of use of phone on the street it turns into pumpkin. For prevention of this event external accumulators, an aka of PowerBank, an ak "banks" are since ancient times used.
But with present dollar rate began to purchase a good can a little, em, risky because of threat of amfibiotropny asphyxia because only one good accumulator of 18650 type costs more than 8 dollars. And their really capacious can is necessary 6. Plus a case — still to add dollars 8-12. Total ~ 60 dollars.
Yes, there are Chinese shops which trade like original Xiaomi of dollars for 25. But all problem is that they that "type original" and that actually will arrive — is not known to anybody.
the problem of cheap Chinese cans consists in that to show such digits, and an ambush that they are typed disgusting quality by accumulators.
It is dangerous to develop photo cells from a perovskite in Russia. But in other countries very actively study this mineral which shows promising results. For example, specialists from the Swiss federal laboratory of materials science and technology (EMPA) suggest to produce two-layer photo cells: a high translucent layer from a perovskite, and the second — on the basis of silicon. As each material absorbs light of a different range, overall effectiveness significantly increases.
Only in September the head of Tesla Motors Ilon Mask provided new model of the car, Tesla Model X. And now the electric vehicle came to production. At the same time the price is already known officially — for the buyer basic model, Tesla Model X 70 D, will cost $80000. It is the price without options, discounts and any incentive bonuses. At 70D the complete drive, the accumulator with a capacity of 70 kWh and all other buns promised earlier.
It is interesting that the cost of models 90D and P90D is unknown, will provide price policy concerning these Tesla models a bit later. But all models have a key feature: doors open up in a special way — the computer system evaluates a surrounding situation, managing doors so that not to touch the cars (or other objects) which are nearby.
Scientists managed to manufacture electronic circuits in a plant (rose) of university of Linchyopinga. The technology is rather unique: live vessels become impregnated with recently discovered PEDOT-S:H polymer then begin to carry out electric current. Or to change light at different strength of current (a kind of PEDOT polymer), creating the "live" display. In principle, it is attempt to turn a plant into the biological computer with chips and the screen.
