Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Bad form Sir !!  >:(

Are you multi lingual ??

Wesley has helped us in so many ways. I feel you owe him an apology !!

Grumage.

100% agreed.  Good post Sir.

Apparently the ferrite pot cores are not necessary. Akula has shown several different versions that don't use the pot core.... it is another Red Herring in my opinion. Good that you are trying them though... but I am building this version which does not include the pot core, just an ordinary flyback transformer ferrite. Of course Russian ferrites are special..... aren't they?

Yes the russian ferrites must be special ;)
I also do not understand Akula, first he makes kilowat device and now he makes a led circuit because it's popular in forums. Also Delamorto made device with 2 bright leds last year in russian forums, now he starts over to convince us with one led. I bed there is a small hidden battery maybe in capacitor.

Хорошо я объясню принцип резонанса и как его найти. Только от этого мой карман тяжелее не станет  :-\.
Я показывал в "Фонарик видео 1" как я нашел резонанс с ферритовыми чашками, сейчас объясню подробно.
На каркас мотается катушка, ее индуктивность в чашках должна быть 115 uH, на чашки наклеивается медная фольга, к ней подключаете осцилограф. Генератором прямоугольника ищите резонансную частоту феррита, так как он сегнетоэлектрик то в резонансе у него синус будет увеличиваться, максимальная амплитуда синуса- наша частота. Это способ узнать частоту любого феррита в домашних условиях  :). Далее все просто, чтоб использовать этот резонанс - нужно его снимать, для этого мотается контур LC на эту частоту резонанса. Один конец контура всегда подключен на входящий конденсатор, а второй коммутируется ключом. Вот так это работает, да на советских ферритах это просто.

Well , I will explain the principle of resonance and how to find it . Only from my pocket harder will not  :-\ .
I showed in the " Фонарик видео1" I found resonance with ferrite cups, now explain in detail .
On the frame is wound coil , its inductance in cups should be 115 uH, cups on a copper foil glued to it connect oscilloscope . Generator rectangle looking resonant frequency ferrite , as it is in resonance ferroelectric his sinus will increase, the maximum amplitude of the sine - our band. It is a way to learn any frequency ferrite at home :) . Then everything is simple to use this resonance - you need to take it off , this teeter LC circuit for the frequency of resonance. One end of the circuit is always connected to the incoming capacitor , and the second key is switched . Here 's how it works , but on the Soviet ferrites is easy.

Молодец что рассказал, но поясню что в генераторе импульсов есть dc-dc преобразователь в принципиальной схеме которую ты кинул.
