Is joule thief circuit gets overunity?

[ltseung888]

I was reading the book "The Chinese Dream" by Helen Wang.  In the book, she mentioned that China should pour much more resources in Research now.  The simple copying or manufacturing period is over.

Energy Research is and will be an area worth much research.  The traditional mode of years of study, peer review papers or confidential laboratories may be outdated.  USA, Japan and other countries are increasing money supply to boost the economy.  Another term is to pump money into "meaningful economic activities". 

The posts and comments in the last few months at least helped to identify the procedures and pitfalls in using a relatively inexpensive oscilloscope to measure Input and Output Power.  It also pointed to the potential "bringing-in" or "leading-out" of electrosmog as a source of energy.  It did not rule out the possibility of another "not yet well understood" source related to oscillation and resonance.

I sow seeds.  The seeds may or may not bear fruit.  But much watering, fertilizing, weeding etc. will be required.  The result of my postings, hopefully, will result in much more resources poured into the energy research field.  The "farmers" or researchers in China are reading other work such as those from Lasersaber etc.

I know my limitations.  I just contribute what I can to the pursuit of "meaningful economic activities".....

God Bless

The "noise" shown on recently posted
photos of the scope display looks very
familiar.  Would your setup be near an
AM radio transmitter perhaps?

While attending Navy Electronics Technician
"A" School at Treasure Island near San
Francisco in 1961 we noticed the same
sort of noise in many of our laboratory
sessions.  Treasure Island was across the
bay from a strong AM Country and Western
station (can't remember the callsign but
the music was pretty good) located right
on the shore at Oakland just north of the
bay bridge about one mile or so distant.

@SeaMonkey,
The various pictures were taken in three different locations.  One was at Zhou's shop amongst thousands of other small electronic stores.  I should say - counters or tables - rather than stores.  The spikes were most noticeable.  Another place was the lab of Dr. Ting who was experimenting with wireless Joule Thief or remote charging.  The third place was my bedroom.  My bedroom was inside a typical residential area of Hong Kong with skyscapters all around.  When one tried to find routers, one could see almost an unending list with at least a dozen showing strong signals.

Thus I did not rule out that the long lighting of the LED at around 0.4V was due to EM noise.  Dr. Ting demonstrated that EM Noise was most probably a factor when he turned on his wireless Joule Thief setup and brought it close to my Joule Thief.  The spikes on the scope were much higher.....

I shall bring the Atten to Mr. T S Lau's place.  His window was facing a Power Line a few hundred meters away.  I shall compare that with a location away from "civilization".....

As I have shown, the noise voltage measured on the scope for the current waveforms does not reflect the actual currents in the circuit when the current magnitudes are well down into the noise level. As the input voltage drops, the current draw is getting lower and lower, so it wouldn't be surprising that the rate of discharge for a battery or a super cap will slow down quite a bit as the input voltage drops into the low range. When the input voltage falls below about .4 volts or so, the power dissipation of the JT circuit is getting quite low, so the power drain on a battery or a super cap will be very little in this operating range.

One experiment you could do to try to determine if ambient noise pickup is having any effect on circuit performance is to decide on an exact circuit configuration and starting input voltage setting such as 20F super caps set to say 0.4V, and then time how long it takes for the LED to turn off in a location with less ambient noise compared to a location with noticeably higher ambient electrical noise. You would have to accurately measure the input starting voltage with a scope or decent multimeter for the test to be valid however. You would probably want to make a least a few test runs at each location to get an indication of how consistent the discharge times are for the same location and same circuit configuration and input voltage. You would want to keep the circuit board away from devices that generate a strong EM field like power supplies that have large power transformers or switch mode power supplies, etc., as we know that devices that have fairly strong EM fields around them will definitely affect the circuit performance. This assumes you are interested in trying to determine the effects of the ambient electrical noise level on circuit performance and not the effect of stronger EM fields that can be generated by certain electronics devices. Just to clarify, I make a distinction between the ambient electrical noise level that exists when one is not close to any electronics devices that have a strong EM field around them, and stronger EM fields that can be encountered around or close to certain types of electronics devices, or AC power lines, etc. No doubt stronger EM fields could very well have some impact on the JT circuit performance, and as we know such stronger EM fields could make the LED light without any power applied to the circuit. I wouldn't call such stronger EM fields 'ambient electrical noise' however.

The EM noise from the Power Lines at T S Lau's home is confirmed.

The Forever Lighted Lamp Project has been started.  The initial goal is lighting the LED with the EM noise for at least 3 months.  Review and improve as needed.

The two presentation files have been shown to people with plenty of time and people with plenty of money.  Team them up and get people with plenty of expertise.....

The "One World" paradigm shift has started???
