So does this mean the LED has been lit for a week and the Batt V has not gone down?
If so quite impressive.

How many free watts would that be?
I'm wondering what the antenna does in this circuit. I think that is new from my memory.
With the antenna this circuit is looking more like the Morray/Bruce Perreault work.

Which diode is the LED? 



Thanks

Norman
Yes that's right battery voltage did not decrease in a week.
Which antenna? There is no antenna in the circuit!. If you mean red wire, this wire is only for connecting the transistor collector to the circuit.

what you mean about "Which diode is the LED?"

Thanks Erfandl
the drawing here shows the circuit I refered to.
https://overunity.com/6123/joule-thief/msg552564/#msg552564

and I thought all Joule Thief's had an led... and the photo shows that too.
Did I get something twised up?

This photovoltaic cell 1000 times as efficient could couple as a Photonic reactor to the light mod circuit.

A nested tetrahedron of photo cells and LEDS facing in on each other recycling power would deliver more output per mass and volume then a fusion reactor.

The deodechedron consists of individual Tetrahedrons. The flat surface is superior to a spherical one. Nice shape for a "Photonic Reactor".

A little overestimated ! The "1000 times" more are from 0,0...% basic conversion efficiency from ferroelectric material !


The MLU research findings  I see in correlation with Prof. Naoshi Ikeda et al. https://www.greenoptimistic.com/green-ferrite-solar-cell-japan-20110920/ findings !

crystal of RFe2O4

https://worldwide.espacenet.com/publicationDetails/description?CC=US&NR=2011168967A1&KC=A1&FT=D&ND=3&date=20110714&DB=EPODOC&locale=en_EP

[0117] Considering the voltage value of 20V/cm described above, for example, when the thickness of the crystal of RFe2O4 in the electronic device is 1 μm, the phenomenon of a change in state of electrons as described above is caused to appear by applying a voltage of approximately 2 mV to the crystal of RFe2O4.


 Further, considering the manufacture of an integrated circuit by use of a device having such a property, it is possible to configure an electronic circuit which can be driven by several mV.


If a circuit can be operated at approximately 1/1000 of the voltage for a conventional transistor integrated circuit, to simply calculate, it can be expected that its power consumption is ( 1/1000)<2>, that is approximately parts per million in a circuit composed by use of the above-described electronic device, and the performance that its operation speed is thousandfold is obtained.






Sincerely

How much power would a 12 sided dodecahedron collector box of high performance photovoltaic cells generate over an extended run time with the 220 volt LED bulb fully illuminated inside?

A measurement of intensity in Lumans would permit the summation of theoretical power consumption. The comparison would deliver the  actual overunity COP.

12 sided dodecahedron collector box :   size ? solar cell/modul/panel


high performance photovoltaic cells  :     % efficiency related radiation nm wavelength


220 volt LED bulb                           :   red,blue,white,green ?




Jerry Vollands 5x are similar the spanish inventor Baquero Menendez his PV light chamber with 8x 1,8mtr. 240 W panels and 500 sodium lamp as light source


lumen/Watt difference between CFL and LEDs are in the CFL 1 /LED 2 range ,the CFL consume can be reduced with controler :

The module can be understood to be similarly used in combination with a plurality of parallel incandescent lamps or luminaires. Furthermore, the present invention is suitable for use in a lighting system combined either with a filamentous (e.g. tungsten or tungsten-halogen) lamp or a nonfilamentous lamp such as a pressurized gas lamp as used in street lighting systems.

LS gadget mod self charge finally replicated and I'm happy :)

Start voltage: 2.613, After a week it is still at 2.613 volts.

Hi erfandl,

May I ask;
1. what is the voltage value of the electrolytic cap (10,000uF)? 
2. Also there are two ceramic nonpolar caps valued with .0001uF and 220pF in the schematics. Where would 220pF cap go? What are the voltages of these caps in your circuit?
3. I see a variable resistor right next to the LED.  What is the ohm value of it?

Trying to replicate your circuit. Thanks to you! :)

Hi.
1- it's 35V 10000uF
2- two 100v .0001uF capacitor in parallel
3- 100k variable resistor

I wonder if efect would be still there if replace germanium diodes with Schottky ?


Can you give more details , explain how you wound transformer ?

Can you mark on schematic direction of winding coils ? I see there is no 100k resistor on schematic, can you post correct schematic ?
