The largest data-center of Russia will receive energy from the NPP

3 years ago

Kalinin NPP

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.

The seller of Honda arranges test drive on the electric car for one of clients

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.

DIY PowerBank on 17000 fair milliampere-hours

3 years ago
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.

Two-layer translucent photo cells with a film from a perovskite

3 years ago


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.

Production Tesla Model X is begun. The price is from $80000

3 years ago

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.

Plants cyborgs. New polymer turns cages of live plants into electric chains and transistors

3 years ago


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.

The scientific article is published in the Science Advances log.
