Selfrunning cold electricity circuit from Dr.Stiffler

[BEP]

I find this thread fascinating and have no unique explanation for SEC.

However, I have been wondering if the minor photovoltaic effect, found in most LEDs, is part of the process. I've searched the thread and found no mention of it.

Before this post I connected different LEDs to my scope and all had some output under light with the output going to near zero with no light. I ruled out induction by using a small flashlight as the source (sure, some induction there but couldn't be enough to show on a scope.) The LEDs I have are pretty much garden variety and all colors I'm aware of.

Outputs varied from a few hundred micro-volts to almost half a volt under bright light.

Just curious during breaks from another project.

   I ran into a circuit for a solar tracker that used two garden variety green led's for the sensors. Just depends on what you use them for.

Today I tried a simple test placing the whole SEC circuit using the Thomas driver inside a deep aluminum pan. The 36 watt lamp tube and battery pack are elevated above the circuit by five inches. The AV plug is connected to earth ground. The 12v AA battery pack is just sitting on top of the lamp. 60 white LED's are lit bright as well as the 36w lamp. The battery pack is reading 11 volts and the current is 110ma. With this configuration touching anything (pan, battery, lamp tube) dims the lights a bit. The only conventional way I know of to light these tubes without wires is by using RF energy, almost like a compact florescent lamp. The oscillations in the lamp light are curious, some kind of heterodyne or harmonic pattern perhaps? I'm not sure what the amp hour rating of this AA battery pack is, I imagine the circuit would operate until the battery is exhausted, there just seems to be a lot of light production for a one watt power use.

For those interested do a Google on the peak frequency of atmospheric noise (~12Mhz range) and how it varies during the day @amigo this may be a partial answer to your observations.

Thanks for the pointer doc, will read up on the subject more now that I know what to look for

60 white LED's are lit bright as well as the 36w lamp. The battery pack is reading 11 volts and the current is 110ma.

Hmm, some calculation based on my tests with white LED:

One LED @ 1mA takes 2.7mW, @10mA takes 31mW
60 LED @ 1mA -> 162mW; @10mA 1860mW
In your setup the input power is 1.21W -
If we assume that LED and tube emits the same amount of
light - and additional state that the efficiency is almost the same -
we have 600mW for the LED and 600mW for the tube.
This would give a rms current of 4mA for the LED.
It would be interesting to have a reference LED which is operated
with a DC current source as a reference for the electrical
power which operates the LEDs.

Another question is - does the rf field directly excite the phosphor
on the tube - or does it really initiate the gas discharge ?
This would explain the pattern on the tube - this want happen
with gas discharge !?

I?m not sure about the camera used for the photo - but I would say
that this tube is operated in the range of 1 or 2 Watt, not more.

Keep in mind that the human eye adapts in a logarithmic way to the light,
means - the 17mW of optical emission of a normal white LED operated @ 50mA
looks only a little bit brigther than the 4mW operated @ 10mA.
-> you cannot trust your eyes if it comes to optical power.
