Joule Thief

[freepow]

Hello, I'm finally back !
Question... If I am running a  285,000 MCD LED rated at (3 volts, 100 ma) from 3volt battery source,
Could I with that 100 ma current running through the LED...charge another 3 volt battery, just like its self recharging, Then when the first battery is flat, switch the batterys over and start again ?
I heard that the LED is not using up the 100 ma, its just going through it !

 :)Me again !
Also I strung up a 90 foot long wire outside for an antenna, its about 6-7 feet off the ground, also a nice galv-iron pipe in the ground for a good ground connection, I have the antenna comming inside also the ground pipe connected seperatly comming inside also...
I connected the antenna to the (+) input of a simple joule thief, then the ground pipe connection to the
(-) input of the simple joule thief, and to my surprise I am getting just over
3 volts AC, just over 2.5 volts DC, and only 3.14 ma. Its free power but not sure how to raise the current higher so I can light a LED !   Any ideas would be appreciated, thanks !

Just use a germanium transistor.  They will turn on with almost no ma!!  I believe Pirate and Gadgetmall have done this already.

I believe that Gadgit has done that

I have came close ......but  I have been  feeding  the  power back to the  original  battery



Do not  put the  LED  in the original  JT position.
Use  secondarys for everything .



About  your  antenna  collector
I have read that the higher  the wire is  the higher  the voltage gets .
I believe that a longer  wire  will  give you more power .

I have not  expermented   with that kind of system  because  I see no way to  protect  the system from lightning .       
Power  collectors are good ..........lightning collectors  connected to your  electronic stuff is not  good .

My 90 foot long, 6-7 foot high long wire antenna + my ground pipe connection gives me as follows...
5 volts (AC) and only .06 ma  NIGHTIME measurement
6 volts (AC) and only .13 ma  DAYTIME  measurement

When i use this to power simple joule thief it measures as follows...
3.1 volts (AC) and 2.6 volts (DC) and 3.14 ma NIGHTIME measurement
3.6 volts (AC) and 2.9 volts (DC) and 3.45 ma DAYTIME  measurement !

Why a higher voltage and current during daytime ? Anybody know why ?

Any way to raise current higher so i can light LED ?

This is free power that I am getting from this system !  Anyone tried this ?
