The DC (direct current) 'nano-grid' – a more reliable solution for Areas and Islands of Light

The regular electrical grid is, as nowadays in AC (and using transformers), that one where you have power plants far from where the electricity is consumed, and by using transmission lines to carry the power over long distances.

But it might be also the case where you can also create smaller-sized grids where the generation and consumption of electricity is closer.

Despite, as usual, these smaller grids are also connected to the larger grid, and thus also can operate independently of the outside grid – not this is the case of interest for out Islands and Areas of Light.

What is used as a term as a 'nano-grid', is a grid that is generally small, in the size of a single building.

These small grids can be primarily DC only, and, the more that independent it is and the more the smaller it gets, the more properly it will be of 24/36/48V DC, - (ELVDC)

and also because of the renewable (or 'free') energy that is generated into that area.

"LA REVANCHE" - Rewinning  the War of Currents


The DC (direct current), a more reliable form of power distribution for 'buildings'.

The same: The DC, much more reliable for off-grid dwellings  generally, and for our Islands and Areas of Light particularly...


In nowadays terms, the rewinning of the war of currents means not necessarily Edison against Tesla, but rather, Edison and Tesla on one side, and... the disgusting 50/60HZ wired power grid system (with all which is behind it) on the other side.
https://en.wikipedia.org/wiki/War_of_the_currents
https://study.com/academy/lesson/thomas-edison-george-westinghouse.html

In the terms of these claims, the fight must rewin this war, for DC in favor of Edison, and for wireless transmission, high frequency, and free energy in favor of Tesla, on the same side of the battle.

A kind of particularity of this 'war' is in the sense that it may be won individually, against the system.

So, each off-grid home, which is (independently from the grid system) powered by only DC grid is a winner of this war, may its owners be or not awakened, or part of (what we call) the Light Community.

Electricity - 'The return of DC'

Slow Electricity - The Return of DC Power? "This double energy conversion, which generates up to 30% of energy losses, can be eliminated if the building's electrical distribution is converted to DC. Directly coupling DC power sources with DC loads can result in a significantly cheaper and more sustainable solar system."
https://www.lowtechmagazine.com/2016/04/slow-electricity-the-return-of-low-voltage-dc-power.html


"With the gaining of popularity of concept of distribution generation (DG) and sustainable development, DG with renewable energy (RE) sources is one of the possible ways for building energy supply in the future. The current "DC-AC-DC" route from DG to DC loads via inverters may not be rational from the viewpoint of system simplicity and energy efficiency, a review on the current electrical distribution systems should be made. This paper reviews and evaluates possibilities of using DC electrical distribution systems with increasing RE resources and DC loads."

The Ufer Grounding, a more preferable and more reliable electrical earth grounding for our Areas and Islands of Light.


"The Ufer Ground is an electrical earth grounding method developed during World War II. It uses a concrete-encased electrode to improve grounding in dry areas. The technique is used in construction of concrete foundations." 
https://en.wikipedia.org/wiki/Ufer_ground


https://www.inspectorsjournal.com/topic/1782-grounding-rebar-in-a-foundation/

https://www.ecmag.com/section/codes-standards/solid-ground-defining-and-understanding-ufer-ground

https://www.contractortalk.com/f77/rebar-grounding-electrode-question-77624/


A particular case of Ufer Grounding for our Islands and Areas of Light infrastructure development:
the stone masonry footing with plain concrete bed.

https://theconstructor.org/building/stone-masonry-footing-construction/21549/


The main concern of Areas and Islands of Light has to be the 'rising of consciousness', 'spiritual development' and 'first contact',
but not developing maintenance jobs.

So we have to develop an infrastructure with as less need of maintenance as possible. Isn't it?

We also have to 'forget', to put aside the nowadays 'standards' and 'regulations', at least to the extent at which it does not fit our interest of the Light Communities development...

We have to draw our own instead.

Let's do it together!

ISLANDS and AREAS of LIGHT - Infrastructure Development


Subject: Electricity

The single or three-phase of 220V/50Hz voltage supply, with even a no-active neutral, – a horrible compromise between our new 'breakaway civilization'... and the never ending collapsing world establishment system...

Thus not at all desired, there is a certain likelihood that in the '220V/50Hz world' this power system will be 'forced' to be chosen for our Islands and Areas of Light infrastructure...

Why is it so undesired??

Because it uses an useless high (and dangerous) voltage and an useless low frequency as well, compared to the short distances and small areas in which has it to be utilised.

220V / 50Hz - No Active Neutral

Imagine a world with free energy only, with no reminiscence of an earthling power grid of 50/60Hz 'standardized' voltage supply. Or, try to 'unlearn' (or imagine to forget) all what you learned in school about electricity distribution, and imagine a world in which only Tesla's free energy and wireless power distribution has supposedly been developed.
If it had developed that way, it would have shown it altogether...

Imagine, as an alternative for our Areas and Islands of Light, the 400Hz / 115V system.

So, this might be also the case for Areas and Islands of Light, supplied by free-energy devices (instead  the case for the transportation systems):

“They don’t need to interoperate, for example, with the nearby power grids assembled by other utilities. About the only (inefficient) nod they need to provide to worldwide “mains” standards is, for example, in providing 50 and 60 Hz-compatible power outlets for passengers to use when powering equipment they’ve brought on board, and generated by AC-to-DC rectifiers followed by DC-to-AC inverters. And on that note, 400 Hz has advantages over 50 Hz and 60 Hz from a DC-generation standpoint; the shorter cycle time allows for use of a smaller “droop” capacitor as part of the rectifier circuit.
Keep in mind, too, that the power-carrying wiring harnesses in such transportation systems are hundreds of feet long, not hundreds of miles long; the attenuating effects of series inductance at higher AC frequencies are less of a concern in such cases. Of great concern, conversely, is weight.”

https://www.arrow.com/en/research-and-events/articles/400-hz-power-systems-for-air-sea-and-space

115V / 400Hz - No Active Neutral

Here, a good description of how it may look like:

ISLANDS OF LIGHT


"A prototype will be formed some where in the world. So far the 3 possible locations are Brazil, Crete, and Hungary. The first step is to build an infrastructure."

https://peterpansblog.com/2019/03/27/personal-notes-of-soul-family-conference-budapest/comment-page-1/

AREAS OF LIGHT - GEOMANCY

Geomancy (Greek for "earth divination") is the art of placing or arranging buildings or other sites auspiciously.
The Geomancer engages with contemporary building sites and materials.

Even these kinds of technical issues will be addressed in an 'organic holistic way' as might they arise in the forming of Islands of Light, we consider to make the steps we can, in the respect of the idea that "the first step is to build an infrastructure", as we can do with our knowledge and expertise.

The other spiritual concerns will be brought by someone else whose best expertise is in this area.

And, Yes!... It is not about general electricity, as we know it.
It is about specific issues concerning the living in Islands and Areas of Light. This is its intent, to draw designs of electrical concern in the respect of Areas of Light development.

How do you see the use of electricity, including free energy, in this communities?
Would you use general standards, or would you draw specific ones?
Would you use general apparatus (i.e. lighting units), or would you have some specific ones?
If you can, please give most suggestion you can, so, we take it into consideration…

In any way, it seems very disappointing to seed our breakaway civilization with the disgusting three-phase 3x400/230 voltage supply with active grounded neutral and stray voltages as well, to be used in our geomantic architecture sacred geometry buildings...

"They are the seeds of the future Breakaway civilization on the surface of the planet. The time is now." http://2012portal.blogspot.com/2019/01/bubbles-of-heaven.html


Examples are given in the pages of our blog (some are not public, so you have to keep the link when is given) for some lighting units using preferred natural numbers of sound frequencies, and
'natural occurring' numbers:

https://en.wikipedia.org/wiki/Mathematical_constant#Apéry's_constant_ζ(3)

http://math.ucr.edu/home/baez/constants_table.pdf

Dimension of products are set using these numbers.

This can extend to any kind of design, architecture and else.

Don't say please,... that you can use in a design only the golden ratio, for all the component parts of the design. Or in some cases you need another ratio from some purposes, so you have where to chose from.

Our designs might be also an example in this respects, but not only to be considered as some, let's say, ellipsoidal and 'stumps' or flowers like looking  products...
