Morning exercises of the apartment on the exercise bike

2 years, 10 months ago


The executive director of the company 5-hour Energy Manodzh Bkhargava (Manoj Bhargava) became the founder of new business of Free Electric. Now it is going to do exercise bikes. But not normal, and with the electric generator and the accumulator. At the same time there will be enough 60 minutes of training for power supply of the small house or the apartment within a day.

Start of ITER is postponed a minimum for 6 years

2 years, 10 months ago

Current status of construction of the reactor

In May of last year on Geektimes news that production of parts for the thermonuclear reactor ITER at last began was published. The term of launch of the reactor — was specified 2019 in the official plan. Start of ITER, unfortunately, is postponed for 6 years, that is somewhere for 2025.

Participants of the command developing ITER are going to specify date still. For this purpose need to gather delegations from China, the EU, Russia, India, Japan, the USA, South Korea. At the same time, the plan of works for 2016-2017 is already ready. This plan (or will not be) in June, 2016 will be approved — for this date the general appointment is made.

Relsotron on 27 kilojoules

2 years, 11 months ago

The most powerful amateur relsotron


Relsotron is an electric accelerator of masses. The shell is located between two electrodes which are connected to a source of a direct current. The shell closes electrodes and purchases acceleration owing to Lorentz force. Relsotron is a pulse device. In practice often functioning is ensured by condensers which are discharged during a moment of second.

By means of a relsotron the shell can give very big acceleration. This acceleration can be far higher, than in the traditional weapon in which the bullet is set in motion by chemical energy of reaction of burning of gunpowder. Relsotron is the perspective weapon. In certain cases the speed of a shell is measured by thousands of meters per second that promises enormous destructions, high range of firing and complexity of protection against defeat. At the moment any country in the world is not armed with relsotron. Now there are only test samples. In particular, over relsotrony for ship arms the fleet of the USA works.

Relsotron is two rails, a shell and a current source. The general simplicity of construction attracts fans. Somebody collected by Xtamared the wearable sample. Energy of a shot makes 1,8 kilojoules of energy. (It is digit of energy of a charge in condensers. Losses are huge and to compare to energy of a shot of the boss of AK-74 of caliber 5,45×39 mm — about 1,3 kJ — are not necessary.) The group of other handymen collected the relsotron, and its power is far higher — is in condensers to 27 kJ of energy. As showed tests, the shot from this relsotron is already deadly.

Galvanic isolation. Who, if not an optron?

2 years, 11 months ago

There is in electronics such concept as galvanic isolation. Its classical determination — transmission of energy or a signal between electric chains without electric contact. If you the beginner, then this formulation seems to very general and even mysterious. If you have engineering experience or just well remember physics, then most likely already thought about transformers and optrons.

Article under a cat is devoted to different methods of galvanic isolation of digital signals. Let's tell why it in general is necessary and as vendors implement an insulating barrier "in" modern chips.

The robot bug "eats" microbes to purify water and to receive energy for work

2 years, 11 months ago
Command of scientists made Row-bot of University of Bristol — a prototype of the robot which is intended for movement on a surface of the polluted reservoirs and eating of microbes. The robot uses microbes for receipt from them of energy and further work.

Гигафабрика Tesla будет вторым по величине зданием в мире

Издание Fast Company взяло большое Гигафабрика". Хотя фотография строящегося здания всего одна, журналист узнал массу подробностей относительно проекта: к 2020 году, когда строительство будет закончено, здание фабрики будет лишь немногим меньше сборочного цеха компании Boeing в городе Эверетт(штат Вашингтон), имеющего рекордный мировой объём 13.3 миллиона м3. Впрочем, и это ещё не всё — Маск не собирается на этом останавливаться и пообещал журналисту, что «фабрика взорвёт ему мозг». «Увидишь и поймёшь, насколько это невероятно», — заметил он.

Great Britain will close all coal power stations within 10 years

2 years, 11 months ago

The last fifty coal power stations of Great Britain will be closed within ten years — plans of the government of the country are that. Representatives of appropriate authorities already declared that it will help to move in the direction of more "safe, admissible and pure power sources". Since 2023 prohibitions on all power plants which burn coal will be entered, and in 2025 all remained stations will close.

Now Great Britain receives the majority of the electric power by combustion of combustible minerals. A coal share here — 28% while the most part of energy, 48%, receive from natural gas. The NPPs give another 16% of energy, but by 2023 the majority of the NPP of the country will already become outdated and also will be gradually closed. The government looks for now an opportunity to invest means in more reliable forms of atomic energy (perhaps, the thermonuclear reaction means).

Retro a find — Prima batteries A 316

2 years, 11 months ago
Last Friday sorting blockages of the safe of times of the USSR at office, found the sealed packaging from 4kh "finger-type" batteries. In total nothing, but it were Prima batteries A 316 releases 08.89g (to the word is only 2 years younger than me). Naturally I recognized them, remembered as being a kid asked the father to purchase to me them more for some electronic toy. And, of course, I could not keep and took several pictures.



It is more than photo under a cat.

The accumulator Li-ion prototype offered Huawei is loaded 10 times quicker than the existing analogs

2 years, 11 months ago
We welcome you on pages of the blog iCover! We hurry to share extraordinary news from the market of rechargeable batteries. This time tries to please the target audience and to afflict competitors the Huawei company which provided on November 13, 2015 on the 56th annual Symposium on electric batteries in the Japanese city of Nagoya (Nagoya) the vision of lithium-ion cells of new generation. Testing of prototypes confirmed their capability to accumulate a charge much quicker than the existing analogs with saving of a resource and initial technical characteristics.

Journalists were invited to look at a new campus of Amazon under construction in Seattle which feature will be both an unusual futuristic architecture, and a heating method — hot water for the building will be delivered from Westin Building data-center. This method is rather effective to warm more than 370 000 sq.m of Amazon Square and nearby office buildings then cooled water will come back in a data-center. This concept was called by the city authorities "what area".
