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.

3 LEDs in series, lighting brilliantly on less than 0.2 volts, finally go out at around 0.140 V or so:

Sorry, no hyperefficient SMDs in use, just discrete components and serendipity. Current draw? Well, to get power for practical light at those low voltages of course the current draw must be relatively high. But I think you can see that at 0.2 volts supply from the 1F capacitor the 3 series LEDs are definitely bright enough for some practical uses.

Wow!  Nice work!

Here is the schematic, and an alternate variation that is more efficient.  The original circuit produces sine waves.  The alternate circuit is trapezoidal with fast edges.

Hi all,

I really like those circuits.  Anyway to get those down from .7 to .3 volts.  I've been looking for a .3v JT without coils.  Glad to see TKs JT runs at .3v even though it uses coils.

Yeah... but it doesn't have any centrifugal-centripetal multispiral dielectric vortices either. That should count for something.

LOL.. I really like your circuit.. thanks for sharing!
