LVDC: the better way
Challenging the status quo

International Electrotechnical Commission – IEC

IEC standards activities on LVDC for electricity:
"LVDC is still considered as a highly disruptive technology • LVDC needs to be safe and reliable, at least to the same extent as AC systems • There is still a lack of standards, with no consensus on DC voltages, earthing for islanded microgrid arrangements, protection solutions, plugs, sockets, etc."

Challenging the status quo. LVDC: the better way

"A disruptive technology is one that displaces an established technology and shakes up the industry or a ground-breaking product that creates a completely new industry."

AND YES!! The old and disgusting established AC system of 50/60Hz MUST BE DISRUPTED!!

It is part of the establishment and must be disrupted!

It carries within (on a 'higher level') the 'darkness' of the suppression of Tesla's free energy, and of the disgusting economic interest of the interconnected 'wire grid' development.

It should be forbidden (strictly not allowed) in our Islands of Light!

Islands and Areas of Light shall at any cost not allow any 'heritage' which carries (even on a 'multidimensional level') any energy of suppression of any kind!
Stop of the 50/60Hz AC in our Light Communities!

The more off-grid you are, the more '(E)LVDC' have you to be.


Islands and areas of Light MUST be 'DC nanogrids' only.

Cobra's free energy devices have to be LVDC only.

If you are involved in Areas of Lights infrastructure development, then please come forward to discuss some important topics. The AC of 50/60Hz has to have NO ROOM in the upcoming 'Breakaway civilization'. Nothing good has it!

It is an unpermitted 'heritage' of the old and disgusting (and neverending collapsing) system.

It must be avoided at any cost!


Solutions are already in place for small off-grid ELVDC nano-grids.

It seems India is in a top position of day by day development.

Material is put together in our blog. Search the links of interest!

Yes, there is a ELVDC standard in place for India!

It is NOT a joke! It may be used for islanded off-grid communities from anywhere, not only India.

Here it is!

If you are an 'indoctrinated professor', part or not of the disgusting establishment, and threatening your students with fail of examination if they ask or question too much,... then should you know your time is up!
You have either to 'awake' or to 'retire'...


Inform yourself! Prepare yourself! Stay tuned!


Appliances for ELVDC are already on market.

AREAS and ISLANDS of LIGHT – Infrastructure Development

Electricity: The 'return' of the DC (direct Current) – LVDC Miscellaneous


A 'war of voltages' is expected to burst out in the 'DC world'...
It might be even more 'everlasting' than the previous 'war of currents', and there is still an unpredictable result...


And, the more, it is already silently unfolding, thus not yet is it 'loudly' declared. And it might last as long,.. till the 'Ascension' process.

Even the 380V DC voltage has not won in this war. The 350V DC and the 400V DC are still walking around, maybe trying to 'depose' it... 

For now, the 'war of voltages' concerning LVDC distribution, (and above the 'established' values of 12, 24, 48V ELVDC), may unfold (and 'rage') including  LVDC voltages as might be 120, 125, 220, 240, 300, 350, 380, 400, and even 550V DC...

So, outside of this war can be considered the DC (extra low) voltages as are 12V, 24V, 48V DC. And,... in this range, as the case may be, have we to design our stand-alone DC (solar power or other kind of 'free energy') nano-grids. 


However, in this 'war of DC voltages' there are expected some 'happy ends' to occur, on some 'fronts' of interests...

Why seem this particular 'war' a non-destructive one, is that all the 'combatants' have the same interest: promoting a 'DC world' against the currently 'all seeing' AC of 50/60Hz  distribution.

This 'war of DC voltages' may lead in fact to a win-win solution on the  'DC side' of combatants,... and hopely to a 'win-lose' in the favor of DC against the highly disgusting AC of 50/60Hz.

And, as expected, a 'proxy' of this undeclared 'war of DC voltages' is also unfolding in the IEC, in order to set up the needed  LVDC standards, finally with a preferable 'win-win' resolution in the form of a broad range of standardized LVDC voltages.

Endless debates are conducted in the IEC Technical Committees. 
The SEG-4 was formed:

Discussion to continue...
