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.

Unfortunately now, Stefan Hartmann is very ill and He needs our help
Stefan wanted that I have all these massive data to get it back online
even being as ill as Stefan is, he transferred all databases and folders
that without his help, this Forum Archives would have never been published here
so, please, as the Webmaster and Creator of this Forum, I am asking that you help him

Thanks to ALL for your help!!

Vladok:'Using Wolfram metall  (Electon capturer - high eV) coated with recomended Ag-O-C'

Ag-O-Cs has very low wf(around 0.1ev).it stretches into the room-temperature far-infrared. What happens to tungsten's wf if you put electric field of 2000v across plates.it plummets.big clues

Good article, shame about the very low current.

Imagine ionizing some rarefied gas and using the same principle to isolate fast from slow molecules with a magnet and an electric field.


Cold and hot electrodes as a result. Maxwels demon!

Low current, true. It will better serve as near 100% thermal converter in high temperature surroundings, like molten salt of thermal storage of thermo-solar powerplants. Number of thermal electrons rise considerably with higher temperature.

FETE.field enhanced thermionic emission.Schottky emission. Schottky effect:
In electron emission devices, especially electron
guns, the thermionic electron emitter will be biased
negative relative to its surroundings. This creates an
electric field of magnitude F at the emitter surface.
Without the field, the surface barrier seen by an
escaping Fermi-level electron has height W equal to
the local work-function. The electric field lowers the
surface barrier by an amount Δ W, and increases the
emission current. This is known as the Schottky
effect (named for Walter H. Schottky) or field
enhanced thermionic emission. It can be modeled
by a simple modification of the Richardson
equation, by replacing W by (W − ΔW).big clues
