"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.

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."
