British households told to prepare for blackouts as coronavirus lockdown goes on | The Independent

Vulnerable people told to ‘keep a torch, hat, gloves and blanket handy’

Customers are advised to keep a “torch handy” as well as “a hat, gloves and blanket” and to trap heat inside their property by closing curtains and doors to any unused rooms.

Vulnerable customers, including those who are elderly, have a disability or medical condition, or have children under the age of five, are told they should keep a power bank fully charged in case their mobile phone battery dies and to use a corded telephone if they can.
Oh my giddy aunt!

Made a cheap and powerful germicidal unit (Quarzlamp, Ozonator) today.
A germicidal lamp is a special type of lamp which produces ultraviolet (UVC) light. This short-wave ultraviolet light disrupts DNA base pairing causing formation of pyrimidine dimers and leads to the inactivation of bacteria, viruses, and protozoa. It can also be used to produce ozone for water disinfection.


Сделал дешёвую и мощную бактерицидную установку (кварцевую лампу, озонатор) сегодня.
Бактерицидная лампа - это специальный тип лампы, которая производит ультрафиолетовый свет. Этот коротковолновый ультрафиолетовый свет разрушает пары оснований ДНК, вызывая образование пиримидиновых димеров и приводит к смерти бактерий, вирусов и простейших. Его также можно использовать для производства озона для дезинфекции воды.
The word "made" is not quite appropriate in this case, because in order to get it, i had to break the 400 watt mercury lamp.


Слово "сделал" не совсем уместно в этом случае, так как чтобы её получить - пришлось разрушить осветительную 400 ваттную ртутную лампу.

It was a standard mercury-vapor 400 E40 lamp (400W, 3.25A, 115V). I put it in a cellophane bag, a foam bag and hit it very carefully with a rubber hammer. As a result, it broke with a ringing slap.


Это была стандартная лампа ДРЛ 400 E40 (400Вт, 3,25А, 115В). Положил её в целофановый пакет, пакет на пенёк и очень осторожно ударил резиновым молотком. В результате она разбилась со звонким хлопком.

In order for illuminating lamp to become germicidal - you only need to break the outer shell without damaging the internal heater containing mercury.


Чтобы из осветительной лампа стала ртутной - нужно разбить только внешнюю оболочку, не повередив внутренний нагреватель, содержащий ртуть.

With pliers removed the glass residue from the lamp base.


Плоскогубцами удалил остатки стекла с цоколя.

On Kreosan's recommendation, i thoroughly wiped the flask with vodka. If don't do that, he says - the flask could explode.


По рекомендации Креосана тщательно протёр колбу водкой. С его слов - если этого не сделать - колба может взорваться.

One of the edges of the flask broke off when the lamp was destroyed, but the integrity of the mercury flask itself was not damaged. In this photo, you can see the mercury inside it.


Один из краёв колбы откололся при разрушении лампы но целосности самой ртутной колбы это не повредило. На этом фото видно ртуть внутри неё.

Powerful mercury lamps of this kind will not be able to operate simply by connecting to the AC mains, but it necessary to use a massive and expensive device known as a throttle (choke) to start them up. I decided to use this simple circuit to start and heat this 400-watt lamp.

Подобные мощные лампы ДРЛ не смогут работать просто от подключения к сети переменного тока, для их запуска используют массивное и дорогостоящее устройство, известное как "дроссель". Для запуска и прогрева этой 400-ваттной лампы я решил использовать эту простую схему.

Found this schematic here. Theoretically, using incandescent bulbs as a load reduces the life of the mercury lamp. But considering that a germicidal lamp will not be used for permanent lighting, but for occasional work for a maximum of 1 hour is a very acceptable solution. Here's the result after connection. Used firewood as a base, where i fixed the lamp holders.


Нашёл эту схему здесь. Теоретически, использование ламп накала в качестве нагрузки снижает срок службы ртутной лампы. Но учитывая что кварцевая лампа будет использовать не для постоянного освещения, а для эпизодической работы неболее 1 часа - это вполне приемлемое решение. Вот результат после подключения. Использовал дрова в качестве основы, куда закрепил ламповые патроны.

Twisted out all the incandescent bulbs before connecting them to the mains. After connecting to the mains - screwed in one of those lamps.


Перед подключением к сети выкрутил все лампы накаливания. После подключения к сети - вкрутил одну из ламп.

The germicidal lamp (located in another room during the test run) began to flicker and began to gradually heat up.


Бактерицидная лампа (расположенная в другой комнате во время пробного запуска) начала мерцать и постепенно нагреваться.

After a few minutes, i screwed in a second incandescent bulb. Here is a video of the load creation process for a similar lamp.


Через несколько минут я вкрутил вторую лампочку накаливания. Здесь видео процесса создания нагрузки для аналогичной лампы.

After 10 minutes, the mercury lamp was shining at full power, there was no need to use a third incandescent lamp for a load.
400-watt mercury lamps for germicidal purposes are much more powerful than commercial market options. According to some claims, in half an hour it can destroy not only mushrooms, but even insects. For mammals, such radiation is also very dangerous, so you need to leave the room during treatment, do not look at the light and ventilate room well (even after a few minutes of work there is a clear smell of ozone).


Уже через 10 минут ртутная лампа светила в полную мощность, использовать третью лампу накаливания для нагрузки не потребовалось.
400-ваттная ртутная лампы для обеззараживания помещений - гораздо мощнее чем, коммерческие варианты на рынки. По некоторым утверждениям, за полчаса работы она способна уничтожить не только грибы, но даже насекомых. Для млекопитающих подобное излучение тоже весьма опасно, поэтому нужно покидать помещение во время обработки, не смотреть на свет и хорошо проветривать (даже после нескольких минут работы остаётся явный запах озона).

Since i have a spectrophotometer, i decided to look at the spectrum of this radiation at the same time.


Так как у меня есть спектрофотометр, решил заодно и посмотреть на спектр этого излучения.

All the components for this powerful bactericide unit cost me less than $10. I did this installation not because of paranoia, giving in to the id2020 promotional campaign, but because i found the fungus/mold spreading in one of the greenhouses before the season started. Theoretically, half an hour of UV treatment will destroy all protozoa, potentially threatening for cultural plants. This kind of radiation easy destroys viruses. In the USSR, they illuminated children in kindergartens for prevention. However, under current conditions, this cargo cult often ends deplorably - there is a known cases when not taking all precautions - a group of children received visible damage to vision. This is a very dangerous procedure for any living creature, think several times before such practices.

Все компоненты для этой мощной бактерицидной установки обошлись мне менее чем в $10. Сделал эту установку не из-за паранои, поддавшись рекламной кампании id2020, а из-за того, что обнаружил распространение грибка/плесени в одной из теплиц перед началом сезона. Теоретически полчаса обработки излучением уничтожит всех простейших, потенциально угрожающих культрным растениям. Вирусов такое излучение на раз истребляет. В СССР обрабатывали им детей в детских садах для профилактики. Правда, в нынешних условиях, этот карго-культ часто заканчивается плачевно - известны случаи, когда не приняв все меры предосторожности - группа детей получала заметные повреждения зрения. Это весьма опасная процедура для любых живых существ, несколько раз подумайте перед подобными практиками.

Made a fairly energy efficient heating system in my room based on cheap ceramic infrared heaters.
Сделал достаточно энергоэффективную систему отопления в своём жилище на основе дешёвых керамических инфракрасных обогревателей:


It has enough a wire and a ceramic lamp sockets to work, and i have also made special protective covers made of metal mesh.
Для их работы достаточно провода и керамических патронов, а также я сделал специальные защитные кожухи из металлической сетки:


Installed 5 x 25-watt heaters on the lower tier of my 10-square-meter room (under dastarkhan).
Развесил 5 25-ваттных обогревателей на нижнем ярусе моей комнаты, площадью 10кв.м. (под дастарханом):


This electric heating system, which consumes only 125 watts per hour of electricity, can provide a temperature difference of up to 20 degrees compared to the outside temperature (exclusive of ventilation).
Такая система электрического обогрева, потребляя всего 125 ватт-час электроэнергии, может обеспечивать разницу температур до 20 градусов, по сравнению с внешней температурой (без учёта проветривания).


The main thing, of course, in this case is that the heated room is well insulated and the generated heat remains in the room.
Главное, конечно, в таком случае - это, чтобы отапливаемое помещение было хорошо утеплено, и генерируемое тепло оставалось в помещении.


The temperature on the heated surface of the 25-watt heater is about 150 degrees Celsius.
Температура на нагреваемой поверхности 25-ваттного обогревателя - около 150 градусов Цельсия.


The temperature of the surfaces closest to the heater does not exceed 50 degrees Celsius.
Температура ближайших к обогревателю поверхностей не превышает 50 градусов Цельсия.


Last year i used similar heaters (they were more powerful) to heat my greenhouse in early spring. When switching on and off regularly with a relay - a few of them failed in less than a season. It turned out that the service life of this type of heaters is influenced by the way they are switched on and off. It is desirable that switching on and off takes place gradually and smoothly. For this purpose i use a simple dimmer, it also allows to regulate the power consumption and acts as a manual heater regulator.
В прошлом году я использовал подобные обогреватели (они были мощнее) для обогрева теплицы ранней весной. При регулярном включении и выключении с помощью реле - несколько штук вышли из строя менее чем, за сезон. Выяснилось, что на срок службы этого типа обогревателей влияет то, как они включаются и выключаются. Желательно чтобы включение и выключение происходило постепенно и плавно. Для этого я использую простейший диммер (светорегулятор), также он позволяет регулировать потребляемую мощность, выполняет роль ручного регулятора обогрева.


In the near future i am going to purchase a powerful digital potentiometer and automate the switching on, off and temperature control depending on the temperature sensor data using a microcontroller.
Also, in case of severe frost, if 5x25W heaters give insufficient heat - i replace one of them with a more powerful 100W.
В скором времени я собираюсь приобрести мощный цифровой потенциометр и автоматизировать включение, выключение и регулирование температуры, в зависимости от данных датчика температуры с помощью микроконтроллера.
Также, в случае сильных морозов, если 5х25ватт обогревателей дают недостаточное количество тепла - я заменяю один из них более мощным 100-ваттным.

How the World's First Digital Circuit Breaker Could Completely Change Our Powered World



This week the world’s first and only digital circuit breaker was certified for commercial use. The technology, invented by Atom Power, has been listed by Underwriters Laboratories (UL), the global standard for consumer safety. This new breaker makes power easier to manage and 3000 times faster than the fastest mechanical breaker, marking the most radical advancement in power distribution since Thomas Edison.

Picture the fuse box in your basement, each switch assigned to different electrical components of your home. These switches are designed to break a circuit to prevent the overloaded wires in your wall from overheating and causing a fire. When this happens, you plod down to your mechanical room and flick the switches on again.

Now multiply that simple system in your home to city high rises and industrial buildings, which might have 250 circuit breakers on any given floor, each one ranging from 15 to 4000 amps at higher voltages. At this scale, the limitations and dangers of a manually controlled power system become much more evident—and costly.
Ready for the scary part, the one involving phones?
“Now I have no moving parts. Now I have the ability to connect things like iPhones and iPads for remote power management, which increases safety and improves efficiency. I can set the distribution panel to a schedule so the flow of power is seamless, unlimited, and shifts between sources automatically. You literally wouldn’t notice. The lights wouldn’t even flicker.”

New #Technique Makes Electricity-Producing #Bacteria More Useful Than Ever

Deeps in mines, at the bottom of lakes, and even in your own gut, bacteria are hard at work producing #electricity in order to survive in environments low in oxygen. These potent little #power producers have been used in speculative experiments and one day may power everything from #batteries to “biohomes.”

There are many types of bacteria capable of producing electricity but some are better at it than others. The trouble with these bacteria is that they are difficult and expensive to grow in a lab setting, slowing down our ability to develop new technologies with them. A new technique developed by #MIT engineers makes sorting and identifying electricity-producing bacteria easier than ever before which may make them more readily available for us in technological applications...
